“In the Sherman Act, Congress tasked courts with enforcing a policy of competition on the belief that market forces“yield the best allocation” of the Nation’s resources. National Collegiate Athletic Assn. v. Board of Regents of Univ. of Okla., 468 U. S. 85, 104, n. 27 (1984). The plaintiffs before us brought this lawsuit alleging that the National Collegiate Athletic Association (NCAA) and certain of its member institutions violated this policy by agreeing to restrict the compensation colleges and universities may offer the student-athletes who play for their teams. After amassinga vast record and conducting an exhaustive trial, the district court issued a 50-page opinion that cut both ways. The court refused to disturb the NCAA’s rules limiting undergraduate athletic scholarships and other compensation related to athletic performance. At the same time, the court struck down NCAA rules limiting the education-related benefits schools may offer student-athletes—such as rules that prohibit schools from offering graduate or vocational school scholarships. Before us, the student-athletes do not challenge the district court’s judgment. But the NCAA does. In essence, it seeks immunity from the normal operation of the antitrust laws and argues, in any event, that the district court should have approved all of its existing restraints. We took this case to consider those objections.

From the start, American colleges and universities have had a complicated relationship with sports and money. In 1852, students from Harvard and Yale participated in what many regard as the Nation’s first intercollegiate competition—a boat race at Lake Winnipesaukee, New Hampshire. But this was no pickup match. A railroad executive sponsored the event to promote train travel to the picturesque lake. T. Mendenhall, The Harvard-Yale Boat Race 1852– 1924, pp. 15–16 (1993). He offered the competitors an all expenses-paid vacation with lavish prizes—along with unlimited alcohol. See A. Zimbalist, Unpaid Professionals 6–7 (1999) (Zimbalist); Rushin, Inside the Moat, Sports Illustrated, Mar. 3, 1997. The event filled the resort with “life and excitement,” N. Y. Herald, Aug. 10, 1852, p. 2, col. 2,and one student-athlete described the “‘junket’” as an experience “‘as unique and irreproducible as the Rhodian colossus,’” Mendenhall, Harvard-Yale Boat Race, at 20.

Life might be no “less than a boat race,” Holmes, On Receiving the Degree of Doctor of Laws, Yale University Commencement, June 30, 1886, in Speeches by Oliver Wendall Holmes, p. 27 (1918), but it was football that really caused college sports to take off. “By the late 1880s the traditional rivalry between Princeton and Yale was attracting 40,000 spectators and generating in excess of $25,000 . . . in gaterevenues.” Zimbalist 7. Schools regularly had “graduate students and paid ringers” on their teams. Ibid.

Colleges offered all manner of compensation to talented athletes. Yale reportedly lured a tackle named James Hogan with free meals and tuition, a trip to Cuba, the exclusive right to sell scorecards from his games—and a job as acigarette agent for the American Tobacco Company. Ibid.; see also Needham, The College Athlete, McClure’s Magazine, June 1905, p. 124. The absence of academic residency requirements gave rise to “‘tramp athletes’” who “roamed the country making cameo athletic appearances, moving onwhenever and wherever the money was better.” F. Dealy, Win at Any Cost 71 (1990). One famous example was a law student at West Virginia University—Fielding H. Yost—“who, in 1896, transferred to Lafayette as a freshman just in time to lead his new teammates to victory against its arch-rival, Penn.” Ibid. The next week, he “was back at West Virginia’s law school.” Ibid. College sports became such a big business that Woodrow Wilson, then President of Princeton University, quipped to alumni in 1890 that “‘Princeton is noted in this wide world for three things: football, baseball, and collegiate instruction.’” Zimbalist 7.

By 1905, though, a crisis emerged. While college footballwas hugely popular, it was extremely violent. Plays like the flying wedge and the players’ light protective gear led to 7football fatalities in 1893, 12 deaths the next year, and 18 in 1905. Id., at 8. President Theodore Roosevelt responded by convening a meeting between Harvard, Princeton, andYale to review the rules of the game, a gathering that ultimately led to the creation of what we now know as the NCAA. Ibid. Organized primarily as a standard-settingbody, the association also expressed a view at its founding about compensating college athletes—admonishing that“[n]o student shall represent a College or University in any intercollegiate game or contest who is paid or receives, directly or indirectly, any money, or financial concession.” Intercollegiate Athletic Association of the United States Constitution By-Laws, Art. VII, §3 (1906); see also Proceedingsof the Eleventh Annual Convention of the National Collegiate Athletic Association, Dec. 28, 1916, p. 34.

Reality did not always match aspiration. More than two decades later, the Carnegie Foundation produced a reporton college athletics that found them still “sodden with the commercial and the material and the vested interests that these forces have created.” H. Savage, The Carnegie Foundation for the Advancement of Teaching, American College Athletics Bull. 23, p. 310 (1929). Schools across the country sought to leverage sports to bring in revenue, attract attention, boost enrollment, and raise money from alumni. The University of California’s athletic revenue was over$480,000, while Harvard’s football revenue alone came in at $429,000. Id., at 87. College football was “not a student’sgame”; it was an “organized commercial enterprise” featuring athletes with “years of training,” “professional coaches,” and competitions that were “highly profitable.” Id., at viii.

The commercialism extended to the market for student-athletes. Seeking the best players, many schools actively participated in a system “under which boys are offered pecuniary and other inducements to enter a particular college.” Id., at xiv–xv. One coach estimated that a rival team “spent over $200,000 a year on players.” Zimbalist 9. In 1939, freshmen at the University of Pittsburgh went onstrike because upperclassmen were reportedly earning more money. Crabb, The Amateurism Myth: A Case for aNew Tradition, 28 Stan. L. & Pol’y Rev. 181, 190 (2017). In the 1940s, Hugh McElhenny, a halfback at the University of Washington, “became known as the first college player ‘ever to take a cut in salary to play pro football.’” Zimbalist 22–23. He reportedly said: “‘[A] wealthy guy puts big bucks under my pillow every time I score a touchdown. Hell, I can’t afford to graduate.’” Id., at 211, n. 17. In 1946, a commentator offered this view: “[W]hen it comes to chicanery, double-dealing, and general undercover work behind the scenes, big-time college football is in a class by itself.” Woodward, Is College Football on the Level?, Sport, Nov. 1946, Vol. 1, No. 3, p. 35.

In 1948, the NCAA sought to do more than admonish. It adopted the “Sanity Code.” Colleges Adopt the ‘Sanity Code’ To Govern Sports, N. Y. Times, Jan. 11, 1948, p. 1,col. 1. The code reiterated the NCAA’s opposition to “promised pay in any form.” Hearings before the Subcommittee on Oversight and Investigations of the House Committee on Interstate and Foreign Commerce, 95th Congress, 2d Sess.,pt. 2, p. 1094 (1978). But for the first time the code also authorized colleges and universities to pay athletes’ tuition. Ibid. And it created a new enforcement mechanism— providing for the “suspension or expulsion” of “proven offenders.” Colleges Adopt ‘Sanity Code,’ N. Y. Times, p. 1, col. 1. To some, these changes sought to substitute a consistent, above-board compensation system for the varying under-the-table schemes that had long proliferated. To others, the code marked “the beginning of the NCAA behaving as an effective cartel,” by enabling its member schools to set and enforce “rules that limit the price they have to pay fortheir inputs (mainly the ‘student-athletes’).” Zimbalist 10.

The rules regarding student-athlete compensation haveevolved ever since. In 1956, the NCAA expanded the scopeof allowable payments to include room, board, books, fees, and “cash for incidental expenses such as laundry.” In re National Collegiate Athletic Assn. Athletic Grant-in-Aid Cap Antitrust Litig., 375 F. Supp. 3d 1058, 1063 (ND Cal.2019) (hereinafter D. Ct. Op.). In 1974, the NCAA beganpermitting paid professionals in one sport to compete on anamateur basis in another. Brief for Historians as Amici Cu6riae 10. In 2014, the NCAA “announced it would allow athletic conferences to authorize their member schools to increase scholarships up to the full cost of attendance.” O’Bannon v. National Collegiate Athletic Assn., 802 F. 3d 1049, 1054–1055 (CA9 2015). The 80 member schools of the “Power Five” athletic conferences—the conferences with the highest revenue in Division I—promptly voted to raise their scholarship limits to an amount that is generally several thousand dollars higher than previous limits. D. Ct. Op., at 1064.

In recent years, changes have continued. The NCAA has created the “Student Assistance Fund” and the “Academic Enhancement Fund” to “assist student-athletes in meeting financial needs,” “improve their welfare or academic support,” or “recognize academic achievement.” Id., at 1072. These funds have supplied money to student-athletes for “postgraduate scholarships” and “school supplies,” as well as “benefits that are not related to education,” such as “lossof-value insurance premiums,” “travel expenses,” “clothing,” and “magazine subscriptions.” Id., at 1072, n. 15. In 2018, the NCAA made more than $84 million available through the Student Activities Fund and more than $48 million available through the Academic Enhancement Fund. Id., at 1072. Assistance may be provided in cash or in kind, and there is no limit to the amount any particularstudent-athlete may receive. Id., at 1073. Since 2015, disbursements to individual students have sometimes been tens of thousands of dollars above the full cost of attendance. Ibid.

The NCAA has also allowed payments “‘incidental to athletics participation,’” including awards for “participation orachievement in athletics” (like “qualifying for a bowl game”)and certain “payments from outside entities” (such as for“performance in the Olympics”). Id., at 1064, 1071, 1074. The NCAA permits its member schools to award up to (but no more than) two annual “Senior Scholar Awards” of

Opinion of the Court
$10,000 for students to attend graduate school after their athletic eligibility expires. Id., at 1074. Finally, the NCAAallows schools to fund travel for student-athletes’ family members to attend “certain events.” Id., at 1069.
Over the decades, the NCAA has become a sprawling enterprise. Its membership comprises about 1,100 colleges and universities, organized into three divisions. Id., at 1063. Division I teams are often the most popular and attract the most money and the most talented athletes. Currently, Division I includes roughly 350 schools divided across 32 conferences. See ibid. Within Division I, the most popular sports are basketball and football. The NCAA divides Division I football into the Football Bowl Subdivision (FBS) and the Football Championship Subdivision, with the FBS generally featuring the best teams. Ibid. The 32 conferences in Division I function similarly to the NCAA itself,but on a smaller scale. They “can and do enact their own rules.” Id., at 1090.

At the center of this thicket of associations and rules sits a massive business. The NCAA’s current broadcast contract for the March Madness basketball tournament is worth $1.1 billion annually. See id., at 1077, n. 20. Its television deal for the FBS conference’s College Football Playoff is worth approximately $470 million per year. See id., at 1063; Bachman, ESPN Strikes Deal for College Football Playoff, Wall Street Journal, Nov. 21, 2012. Beyondthese sums, the Division I conferences earn substantial revenue from regular-season games. For example, the Southeastern Conference (SEC) “made more than $409 million inrevenues from television contracts alone in 2017, with its total conference revenues exceeding $650 million that year.” D. Ct. Op., at 1063. All these amounts have “increased consistently over the years.” Ibid.

Those who run this enterprise profit in a different way than the student-athletes whose activities they oversee.The president of the NCAA earns nearly $4 million per year. Brief for Players Association of the National Football League et al. as Amici Curiae 17. Commissioners of the top conferences take home between $2 to $5 million. Ibid. College athletic directors average more than $1 million annually. Ibid. And annual salaries for top Division I college football coaches approach $11 million, with some of their assistants making more than $2.5 million. Id., at 17–18.

B The plaintiffs are current and former student-athletes in men’s Division I FBS football and men’s and women’s Division I basketball. They filed a class action against the NCAA and 11 Division I conferences (for simplicity’s sake, we refer to the defendants collectively as the NCAA). The student-athletes challenged the “current, interconnectedset of NCAA rules that limit the compensation they mayreceive in exchange for their athletic services.” D. Ct. Op.,at 1062, 1065, n. 5. Specifically, they alleged that theNCAA’s rules violate §1 of the Sherman Act, which prohibits “contract[s], combination[s], or conspirac[ies] in restraint of trade or commerce.” 15 U. S. C. §1.After pretrial proceedings stretching years, the districtcourt conducted a 10-day bench trial. It heard experts and lay witnesses from both sides, and received volumes of evidence and briefing, all before issuing an exhaustive decision. In the end, the court found the evidence undisputedon certain points. The NCAA did not “contest evidence showing” that it and its members have agreed to compensation limits on student-athletes; the NCAA and its conferences enforce these limits by punishing violations; and these limits “affect interstate commerce.” D. Ct. Op., at 1066. Based on these premises, the district court proceeded to assess the lawfulness of the NCAA’s challenged restraints. This Court has “long recognized that in view of the common law and the law in this country when the Sherman Act was passed, the phrase ‘restraint of trade’ is best read to mean‘undue restraint.’” Ohio v. American Express Co., 585 U. S. ___, ___ (2018) (slip op., at 8) (brackets and some internal quotation marks omitted). Determining whether a restraint is undue for purposes of the Sherman Act “presumptively” calls for what we have described as a “rule of reasonanalysis.” Texaco Inc. v. Dagher, 547 U. S. 1, 5 (2006); Standard Oil Co. of N. J. v. United States, 221 U. S. 1, 60– 62 (1911). That manner of analysis generally requires a court to “conduct a fact-specific assessment of market power and market structure” to assess a challenged restraint’s “actual effect on competition.” American Express, 585 U. S., at ___–___ (slip op., at 8–9) (internal quotation marks omitted). Always, “[t]he goal is to distinguish between restraints with anticompetitive effect that are harmful to theconsumer and restraints stimulating competition that arein the consumer’s best interest.” Ibid. (brackets and internal quotation marks omitted).

In applying the rule of reason, the district court began byobserving that the NCAA enjoys “near complete dominanceof, and exercise[s] monopsony power in, the relevant market”—which it defined as the market for “athletic services in men’s and women’s Division I basketball and FBS football, wherein each class member participates in his or hersport-specific market.” D. Ct. Op., at 1097. The “most talented athletes are concentrated” in the “markets for Division I basketball and FBS football.” Id., at 1067. There are no “viable substitutes,” as the “NCAA’s Division I essentially is the relevant market for elite college football and basketball.” Id., at 1067, 1070. In short, the NCAA and its member schools have the “power to restrain student-athletecompensation in any way and at any time they wish, without any meaningful risk of diminishing their market dominance.” Id., at 1070.

The district court then proceeded to find that the NCAA’scompensation limits “produce significant anticompetitive
effects in the relevant market.” Id., at 1067. Though member schools compete fiercely in recruiting student-athletes, the NCAA uses its monopsony power to “cap artificially the compensation offered to recruits.” Id., at 1097. In a market without the challenged restraints, the district court found,“competition among schools would increase in terms of thecompensation they would offer to recruits, and student-athlete compensation would be higher as a result.” Id., at 1068. “Student-athletes would receive offers that would more closely match the value of their athletic services.” Ibid. And notably, the court observed, the NCAA “did notmeaningfully dispute” any of this evidence. Id., at 1067; see also Tr. of Oral Arg. 31 (“[T]here’s no dispute that the—the no-pay-for-play rule imposes a significant restraint on a relevant antitrust market”).

The district court next considered the NCAA’s procompetitive justifications for its restraints. The NCAA suggestedthat its restrictions help increase output in college sports and maintain a competitive balance among teams. But the district court rejected those justifications, D. Ct. Op., at 1070, n. 12, and the NCAA does not pursue them here. The NCAA’s only remaining defense was that its rules preserve amateurism, which in turn widens consumer choice byproviding a unique product—amateur college sports as distinct from professional sports. Admittedly, this assertedbenefit accrues to consumers in the NCAA’s seller-side consumer market rather than to student-athletes whose compensation the NCAA fixes in its buyer-side labor market. But, the NCAA argued, the district court needed to assess its restraints in the labor market in light of their procompetitive benefits in the consumer market—and the districtcourt agreed to do so. Id., at 1098.

Turning to that task, the court observed that the NCAA’sconception of amateurism has changed steadily over the years. See id., at 1063–1064, 1072–1073; see also supra, at 3–7. The court noted that the NCAA “nowhere define[s] the nature of the amateurism they claim consumers insist upon.” D. Ct. Op., at 1070. And, given all this, the court struggled to ascertain for itself “any coherent definition” of the term, id., at 1074, noting the testimony of a former SEC commissioner that he’s “‘never been clear on . . . what is really meant by amateurism.’” Id., at 1070–1071.

Nor did the district court find much evidence to supportthe NCAA’s contention that its compensation restrictionsplay a role in consumer demand. As the court put it, theevidence failed “to establish that the challenged compensation rules, in and of themselves, have any direct connectionto consumer demand.” Id., at 1070. The court observed, for example, that the NCAA’s “only economics expert on the issue of consumer demand” did not “study any standard measures of consumer demand” but instead simply “interviewed people connected with the NCAA and its schools, who were chosen for him by defense counsel.” Id., at 1075. Meanwhile, the student-athletes presented expert testimony and other evidence showing that consumer demand has increased markedly despite the new types of compensation the NCAA has allowed in recent decades. Id., at 1074, 1076. The plaintiffs presented economic and other evidencesuggesting as well that further increases in student-athlete compensation would “not negatively affect consumer demand.” Id., at 1076. At the same time, however, the district court did find that one particular aspect of the NCAA’s compensation limits “may have some effect in preserving consumer demand.” Id., at 1082. Specifically, the court found that rules aimed at ensuring “student-athletes do not receive unlimited payments unrelated to education” could play some role in product differentiation with professional sports and thus help sustain consumer demand for college athletics. Id., at 1083.

The court next required the student-athletes to show that“substantially less restrictive alternative rules” existed that “would achieve the same procompetitive effect as the challenged set of rules.” Id., at 1104. The district court emphasized that the NCAA must have “ample latitude” to run its enterprise and that courts “may not use antitrust laws to make marginal adjustments to broadly reasonablemarket restraints.” Ibid. (internal quotation marks omitted). In light of these standards, the court found the student-athletes had met their burden in some respects but not others. The court rejected the student-athletes’ challenge to NCAA rules that limit athletic scholarships to thefull cost of attendance and that restrict compensation and benefits unrelated to education. These may be price-fixingagreements, but the court found them to be reasonable inlight of the possibility that “professional-level cash payments . . . could blur the distinction between college sports and professional sports and thereby negatively affect consumer demand.” Ibid.

The court reached a different conclusion for caps on education-related benefits—such as rules that limit scholarships for graduate or vocational school, payments for academic tutoring, or paid posteligibility internships. Id., at 1088. On no account, the court found, could such education-related benefits be “confused with a professional athlete’s salary.” Id., at 1083. If anything, they “emphasize that the recipients are students.” Ibid. Enjoining the NCAA’s restrictions on these forms of compensation alone, the courtconcluded, would be substantially less restrictive than the NCAA’s current rules and yet fully capable of preservingconsumer demand for college sports. Id., at 1088.

The court then entered an injunction reflecting its findings and conclusions. Nothing in the order precluded the NCAA from continuing to fix compensation and benefits unrelated to education; limits on athletic scholarships, for example, remained untouched. The court enjoined the NCAAonly from limiting education-related compensation or benefits that conferences and schools may provide to student-athletes playing Division I football and basketball. App. to Pet. for Cert. in No. 20–512, p. 167a, ¶1. The court’s injunction further specified that the NCAA could continue to limitcash awards for academic achievement—but only so long as those limits are no lower than the cash awards allowed for athletic achievement (currently $5,980 annually). Id., at 168a–169a, ¶5; Order Granting Motion for Clarification of Injunction in No. 4:14–md–02541, ECF Doc. 1329, pp. 5–6 (ND Cal., Dec. 30, 2020). The court added that the NCAA and its members were free to propose a definition of compensation or benefits “‘related to education.’” App. to Pet. for Cert. in No. 20–512, at 168a, ¶4. And the court explained that the NCAA was free to regulate how conferences and schools provide education-related compensationand benefits. Ibid. The court further emphasized that itsinjunction applied only to the NCAA and multi-conference agreements—thus allowing individual conferences (and theschools that constitute them) to impose tighter restrictionsif they wish. Id., at 169a, ¶6. The district court’s injunctionissued in March 2019, and took effect in August 2020.

Both sides appealed. The student-athletes said the district court did not go far enough; it should have enjoined all of the NCAA’s challenged compensation limits, includingthose “untethered to education,” like its restrictions on the size of athletic scholarships and cash awards. In re National Collegiate Athletic Assn. Athletic Grant-in-Aid Cap Antitrust Litig., 958 F. 3d 1239, 1263 (CA9 2020). The NCAA, meanwhile, argued that the district court went too far by weakening its restraints on education-related compensation and benefits. In the end, the court of appeals affirmed in full, explaining its view that “the district courtstruck the right balance in crafting a remedy that both prevents anticompetitive harm to Student-Athletes while serving the procompetitive purpose of preserving the popularity of college sports.” Ibid.

C Unsatisfied with this result, the NCAA asks us to reverse to the extent the lower courts sided with the student-athletes. For their part, the student-athletes do not renew their across-the-board challenge to the NCAA’s compensation restrictions. Accordingly, we do not pass on the rulesthat remain in place or the district court’s judgment upholding them. Our review is confined to those restrictions now enjoined.Before us, as through much of the litigation below, some of the issues most frequently debated in antitrust litigation are uncontested. The parties do not challenge the district court’s definition of the relevant market. They do not contest that the NCAA enjoys monopoly (or, as it’s called on thebuyer side, monopsony) control in that labor market—such that it is capable of depressing wages below competitive levels and restricting the quantity of student-athlete labor.Nor does the NCAA dispute that its member schools compete fiercely for student-athletes but remain subject to NCAA-issued-and-enforced limits on what compensationthey can offer. Put simply, this suit involves admitted horizontal price fixing in a market where the defendants exercise monopoly control.Other significant matters are taken as given here too. No one disputes that the NCAA’s restrictions in fact decrease the compensation that student-athletes receive compared to what a competitive market would yield. No one questionseither that decreases in compensation also depress participation by student-athletes in the relevant labor market—so that price and quantity are both suppressed. See 12 P. Areeda & H. Hovenkamp, Antitrust Law ¶2011b, p. 134 (4th ed. 2019) (Areeda & Hovenkamp). Nor does the NCAA suggest that, to prevail, the plaintiff student-athletes mustshow that its restraints harm competition in the seller-side (or consumer facing) market as well as in its buyer-side (or labor) market. See, e.g., Mandeville Island Farms, Inc. v. American Crystal Sugar Co., 334 U. S. 219, 235 (1948); Weyerhaeuser Co. v. Ross-Simmons Hardwood Lumber Co., 549 U. S. 312, 321 (2007); 2A Areeda & Hovenkamp ¶352c,pp. 288–289 (2014); 12 id., ¶2011a, at 132–134.

Meanwhile, the student-athletes do not question that theNCAA may permissibly seek to justify its restraints in the labor market by pointing to procompetitive effects they produce in the consumer market. Some amici argue that “competition in input markets is incommensurable with competition in output markets,” and that a court should not “tradeoff ” sacrificing a legally cognizable interest in competitionin one market to better promote competition in a different one; review should instead be limited to the particular market in which antitrust plaintiffs have asserted their injury.Brief for American Antitrust Institute as Amicus Curiae 3, 11–12. But the parties before us do not pursue this line.

With all these matters taken as given, we express no views on them. Instead, we focus only on the objections the NCAA does raise. Principally, it suggests that the lower courts erred by subjecting its compensation restrictions toa rule of reason analysis. In the NCAA’s view, the courts should have given its restrictions at most an “abbreviated deferential review,” Brief for Petitioner in No. 20–512,
p.
14, or a “‘quick look,’” Brief for Petitioners in No. 20–520,
p.
18, before approving them.
The NCAA offers a few reasons why. Perhaps dominantly, it argues that it is a joint venture and that collaboration among its members is necessary if they are to offer consumers the benefit of intercollegiate athletic competition. We doubt little of this. There’s no question, for example, that many “joint ventures are calculated to enable firms to do something more cheaply or better than they did it before.” 13 Areeda & Hovenkamp ¶2100c, at 7. And the fact that joint ventures can have such procompetitive benefitssurely stands as a caution against condemning their arrangements too reflexively. See Dagher, 547 U. S., at 7; Broadcast Music, Inc. v. Columbia Broadcasting System, Inc., 441 U. S. 1, 22–23 (1979).

But even assuming (without deciding) that the NCAA isa joint venture, that does not guarantee the foreshortened review it seeks. Most restraints challenged under the Sherman Act—including most joint venture restrictions—are subject to the rule of reason, which (again) we have described as “a fact-specific assessment of market power andmarket structure” aimed at assessing the challenged restraint’s “actual effect on competition”—especially its capacity to reduce output and increase price. American Express, 585 U. S., at ___–___ (slip op., at 8–9) (internalquotation marks omitted).
Admittedly, the amount of work needed to conduct a fairassessment of these questions can vary. As the NCAA observes, this Court has suggested that sometimes we can determine the competitive effects of a challenged restraint in the “‘twinkling of an eye.’” Board of Regents, 468 U. S., at 110, n. 39 (quoting P. Areeda, The “Rule of Reason” in Antitrust Analysis: General Issues 37–38 (Federal JudicialCenter, June 1981)); American Needle, Inc. v. National Football League, 560 U. S. 183, 203 (2010). That is true, though, only for restraints at opposite ends of the competitive spectrum. For those sorts of restraints—rather than restraints in the great in-between—a quick look is sufficient for approval or condemnation.
At one end of the spectrum, some restraints may be so obviously incapable of harming competition that they require little scrutiny. In Rothery Storage & Van Co. v. Atlas Van Lines, Inc., 792 F. 2d 210 (CADC 1986), for example, Judge Bork explained that the analysis could begin and end with the observation that the joint venture under review“command[ed] between 5.1 and 6% of the relevant market.”

Id., at 217. Usually, joint ventures enjoying such smallmarket share are incapable of impairing competition. Should they reduce their output, “there would be no effect upon market price because firms making up the other 94% of the market would simply take over the abandoned business.” Ibid.; see also 7 Areeda & Hovenkamp ¶1507a,
p. 444 (2017) (If “the exercise of market power is not plausible, the challenged practice is legal”); Polk Bros., Inc. v. Forest City Enterprises, Inc., 776 F. 2d 185, 191 (CA7 1985) (“Unless the firms have the power to raise price by curtailing output, their agreement is unlikely to harm consumers,and it makes sense to understand their cooperation as benign or beneficial”).

At the other end, some agreements among competitors so obviously threaten to reduce output and raise prices thatthey might be condemned as unlawful per se or rejected after only a quick look. See Dagher, 547 U. S., at 7, n. 3; California Dental Assn. v. FTC, 526 U. S. 756, 770 (1999). Recognizing the inherent limits on a court’s ability to masteran entire industry—and aware that there are often hard-tosee efficiencies attendant to complex business arrangements—we take special care not to deploy these condemnatory tools until we have amassed “considerable experiencewith the type of restraint at issue” and “can predict withconfidence that it would be invalidated in all or almost all instances.” Leegin Creative Leather Products, Inc. v. PSKS, Inc., 551 U. S. 877, 886–887 (2007); Easterbrook, On Identifying Exclusionary Conduct, 61 Notre Dame L. Rev. 972, 975 (1986) (noting that it can take “economists years, sometimes decades, to understand why certain business practices work [and] determine whether they work because of increased efficiency or exclusion”); see also infra, at 26–27 (further reasons for caution).
None of this helps the NCAA. The NCAA accepts that its members collectively enjoy monopsony power in the market for student-athlete services, such that its restraints can
18 NATIONAL COLLEGIATE ATHLETIC ASSN. v. ALSTON
Opinion of the Court
(and in fact do) harm competition. See D. Ct. Op., at 1067. Unlike customers who would look elsewhere when a small van company raises its prices above market levels, the district court found (and the NCAA does not here contest) thatstudent-athletes have nowhere else to sell their labor. Even if the NCAA is a joint venture, then, it is hardly of the sort that would warrant quick-look approval for all its myriad rules and restrictions.
Nor does the NCAA’s status as a particular type of venture categorically exempt its restraints from ordinary rule of reason review. We do not doubt that some degree of coordination between competitors within sports leagues can be procompetitive. Without some agreement among rivals—on things like how many players may be on the fieldor the time allotted for play—the very competitions that consumers value would not be possible. See Board of Regents, 468 U. S., at 101 (quoting R. Bork, The Antitrust Paradox 278 (1978)). Accordingly, even a sports league withmarket power might see some agreements among its members win antitrust approval in the “‘twinkling of an eye.’” American Needle, 560 U. S., at 203.

But this insight does not always apply. That some restraints are necessary to create or maintain a league sport does not mean all “aspects of elaborate interleague cooperation are.” Id., at 199, n. 7. While a quick look will oftenbe enough to approve the restraints “necessary to producea game,” ibid., a fuller review may be appropriate for others. See, e.g., Chicago Professional Sports Ltd. Partnership

v. National Basketball Assn., 95 F. 3d 593, 600 (CA7 1996) (“Just as the ability of McDonald’s franchises to coordinatethe release of a new hamburger does not imply their ability to agree on wages for counter workers, so the ability of sports teams to agree on a TV contract need not imply anability to set wages for players”).
The NCAA’s rules fixing wages for student-athletes fallon the far side of this line. Nobody questions that Division I basketball and FBS football can proceed (and have proceeded) without the education-related compensation restrictions the district court enjoined; the games go on. Instead, the parties dispute whether and to what extent thoserestrictions in the NCAA’s labor market yield benefits in its consumer market that can be attained using substantially less restrictive means. That dispute presents complexquestions requiring more than a blink to answer.
B Even if background antitrust principles counsel in favor of the rule of reason, the NCAA replies that a particular precedent ties our hands. The NCAA directs our attention to Board of Regents, where this Court considered the league’s rules restricting the ability of its member schoolsto televise football games. 468 U. S., at 94. On the NCAA’s reading, that decision expressly approved its limits on student-athlete compensation—and this approval foreclosesany meaningful review of those limits today.We see things differently. Board of Regents explainedthat the league’s television rules amounted to “[h]orizontalprice fixing and output limitation[s]” of the sort that are“ordinarily condemned” as “‘illegal per se.’” Id., at 100. The Court declined to declare the NCAA’s restraints per se unlawful only because they arose in “an industry” in whichsome “horizontal restraints on competition are essential if the product is to be available at all.” Id., at 101–102. Our analysis today is fully consistent with all of this. Indeed, if any daylight exists it is only in the NCAA’s favor. While Board of Regents did not condemn the NCAA’s broadcasting restraints as per se unlawful, it invoked abbreviated antitrust review as a path to condemnation, not salvation. Id., at 109, n. 39. If a quick look was thought sufficient beforerejecting the NCAA’s procompetitive rationales in thatcase, it is hard to see how the NCAA might object to a court providing a more cautious form of review before reaching a similar judgment here.

To be sure, the NCAA isn’t without a reply. It notes that, in the course of reaching its judgment about television marketing restrictions, the Board of Regents Court commented on student-athlete compensation restrictions. Most
particularly, the NCAA highlights this passage:

“The NCAA plays a critical role in the maintenance of a revered tradition of amateurism in college sports.There can be no question but that it needs ample latitude to play that role, or that the preservation of thestudent-athlete in higher education adds richness anddiversity to intercollegiate athletics and is entirely consistent with the goals of the Sherman Act.” Id., at 120.

See also id., at 101, 102 (the NCAA “seeks to market a particular brand of football” in which “athletes must not be paid, must be required to attend class, and the like”). On the NCAA’s telling, these observations foreclose any rule ofreason review in this suit.

Once more, we cannot agree. Board of Regents may suggest that courts should take care when assessing theNCAA’s restraints on student-athlete compensation, sensitive to their procompetitive possibilities. But these remarks do not suggest that courts must reflexively reject all challenges to the NCAA’s compensation restrictions. Student-athlete compensation rules were not even at issue in Board of Regents. And the Court made clear it was onlyassuming the reasonableness of the NCAA’s restrictions:“It is reasonable to assume that most of the regulatory controls of the NCAA are justifiable means of fostering competition among amateur athletic teams and are thereforeprocompetitive . . . .” Id., at 117 (emphasis added). Accordingly, the Court simply did not have occasion to declare—nor did it declare—the NCAA’s compensation restrictionsprocompetitive both in 1984 and forevermore.

Our confidence on this score is fortified by still another factor. Whether an antitrust violation exists necessarilydepends on a careful analysis of market realities. See, e.g., American Express Co., 585 U. S., at ___–___ (slip op., at 10–12); 2B Areeda & Hovenkamp ¶500, p. 107 (2014). If those market realities change, so may the legal analysis.

When it comes to college sports, there can be little doubt that the market realities have changed significantly since 1984. Since then, the NCAA has dramatically increased the amounts and kinds of benefits schools may provide to student-athletes. For example, it has allowed the conferences flexibility to set new and higher limits on athletic scholarships. D. Ct. Op., at 1064. It has increased the size of permissible benefits “incidental to athletics participation.” Id., at 1066. And it has developed the Student Assistance Fund and the Academic Enhancement Fund, which in 2018 alone provided over $100 million to student-athletes. Id., at 1072. Nor is that all that has changed. In 1985, Division I football and basketball raised approximately $922 million and $41million respectively. Brief for Former NCAA Executives as Amici Curiae 7. By 2016, NCAA Division I schools raised more than $13.5 billion. Ibid. From 1982 to 1984, CBS paid$16 million per year to televise the March Madness DivisionI men’s basketball tournament. Ibid. In 2016, those annual television rights brought in closer to $1.1 billion. D. Ct. Op.,at 1077, n. 20.

Given the sensitivity of antitrust analysis to market realities—and how much has changed in this market—we think it would be particularly unwise to treat an aside in Board of Regents as more than that. This Court may be “infallible only because we are final,” Brown v. Allen, 344

U. S. 443, 540 (1953) (Jackson, J., concurring in result), but those sorts of stray comments are neither.
C The NCAA submits that a rule of reason analysis is inappropriate for still another reason—because the NCAA and
22 NATIONAL COLLEGIATE ATHLETIC ASSN. v. ALSTON
Opinion of the Court
its member schools are not “commercial enterprises” and instead oversee intercollegiate athletics “as an integral partof the undergraduate experience.” Brief for Petitioner in No. 20–512, at 31. The NCAA represents that it seeks to“maintain amateurism in college sports as part of serving [the] societally important non-commercial objective” of“higher education.” Id., at 3.

Here again, however, there may be less of a dispute thanmeets the eye. The NCAA does not contest that its restraints affect interstate trade and commerce and are thus subject to the Sherman Act. See D. Ct. Op., at 1066. The NCAA acknowledges that this Court already analyzed (and struck down) some of its restraints as anticompetitive in Board of Regents. And it admits, as it must, that the Court did all this only after observing that the Sherman Act hadalready been applied to other nonprofit organizations—and that “the economic significance of the NCAA’s nonprofitcharacter is questionable at best” given that “the NCAA andits member institutions are in fact organized to maximize revenues.” 468 U. S., at 100–101, n. 22. Nor, on the other side of the equation, does anyone contest that the status of the NCAA’s members as schools and the status of student-athletes as students may be relevant in assessing consumer demand as part of a rule of reason review. With this much agreed it is unclear exactly what the NCAA seeks. To the extent it means to propose a sort ofjudicially ordained immunity from the terms of the Sherman Act for its restraints of trade—that we should overlook its restrictions because they happen to fall at the intersection of higher education, sports, and money—we cannot agree. This Court has regularly refused materially identical requests from litigants seeking special dispensationfrom the Sherman Act on the ground that their restraintsof trade serve uniquely important social objectives beyondenhancing competition.

Take two examples. In National Soc. of Professional Engineers v. United States, 435 U. S. 679 (1978), a trade association argued that price competition between engineers competing for building projects had to be restrained to ensure quality work and protect public safety. Id., at 679– 680. This Court rejected that appeal as “nothing less thana frontal assault on the basic policy of the Sherman Act.” Id., at 695. The “statutory policy” of the Act is one of competition and it “precludes inquiry into the question whether competition is good or bad.” Ibid. In FTC v. Superior Court Trial Lawyers Assn., 493 U. S. 411 (1990), criminal defense lawyers agreed among themselves to refuse court appointments until the government increased their compensation. Id., at 414. And once more the Court refused to consider whether this restraint of trade served some social good more important than competition: “The social justifications proffered for respondents’ restraint of trade . . . do not make it any less unlawful.” Id., at 424.

To be sure, this Court once dallied with something that looks a bit like an antitrust exemption for professional baseball. In Federal Baseball Club of Baltimore, Inc. v. National League of Professional Baseball Clubs, 259 U. S. 200 (1922),the Court reasoned that “exhibitions” of “base ball” did not implicate the Sherman Act because they did not involve interstate trade or commerce—even though teams regularlycrossed state lines (as they do today) to make money and enhance their commercial success. Id., at 208–209. But this Court has refused to extend Federal Baseball’s reasoning to other sports leagues—and has even acknowledgedcriticisms of the decision as “‘unrealistic’” and “‘inconsistent’” and “aberration[al].” Flood v. Kuhn, 407 U. S. 258, 282 (1972) (quoting Radovich v. National Football League, 352 U. S. 445, 452 (1957)); see also Brief for Advocates for Minor Leaguers as Amicus Curiae 5, n. 3 (gathering criticisms). Indeed, as we have seen, this Court has already recognized that the NCAA itself is subject to the Sherman Act.

The “orderly way” to temper that Act’s policy of competition is “by legislation and not by court decision.” Flood, 407
U. S., at 279. The NCAA is free to argue that, “because ofthe special characteristics of [its] particular industry,” it should be exempt from the usual operation of the antitrust laws—but that appeal is “properly addressed to Congress.” National Soc. of Professional Engineers, 435 U. S., at 689. Nor has Congress been insensitive to such requests. It has modified the antitrust laws for certain industries in the past, and it may do so again in the future. See, e.g., 7 U. S. C. §§291–292 (agricultural cooperatives); 15 U. S. C.§§1011–1013 (insurance); 15 U. S. C. §§1801–1804 (newspaper joint operating agreements). But until Congress saysotherwise, the only law it has asked us to enforce is the Sherman Act, and that law is predicated on one assumption alone—“competition is the best method of allocating resources” in the Nation’s economy. National Soc. of Professional Engineers, 435 U. S., at 695.
III A

While the NCAA devotes most of its energy to resisting the rule of reason in its usual form, the league lodges some objections to the district court’s application of it as well.

When describing the rule of reason, this Court has sometimes spoken of “a three-step, burden-shifting framework” as a means for “‘distinguish[ing] between restraints withanticompetitive effect that are harmful to the consumer and restraints stimulating competition that are in the consumer’s best interest.’” American Express Co., 585 U. S., at ___ (slip op., at 9). As we have described it, “the plaintiff has the initial burden to prove that the challenged restraint has a substantial anticompetitive effect.” Ibid. Should the plaintiff carry that burden, the burden then “shifts to the defendant to show a procompetitive rationale for the restraint.” Ibid. If the defendant can make that showing,“the burden shifts back to the plaintiff to demonstrate thatthe procompetitive efficiencies could be reasonablyachieved through less anticompetitive means.” Id., at ___– ___ (slip op., at 9–10).

These three steps do not represent a rote checklist, normay they be employed as an inflexible substitute for careful analysis. As we have seen, what is required to assess whether a challenged restraint harms competition can varydepending on the circumstances. See supra, at 15–19. The whole point of the rule of reason is to furnish “an enquirymeet for the case, looking to the circumstances, details, andlogic of a restraint” to ensure that it unduly harms competition before a court declares it unlawful. California Dental, 526 U. S., at 781; see also, e.g., Leegin Creative, 551 U. S., at 885 (“‘[T]he factfinder weighs all of the circumstances of a case in deciding whether a restrictive practice should beprohibited as imposing an unreasonable restraint on competition’”); Copperweld Corp. v. Independence Tube Corp., 467 U. S. 752, 768 (1984); 7 Areeda & Hovenkamp ¶1507a,at 442–444 (slightly different “decisional model” using sequential questions).

In the proceedings below, the district court followed circuit precedent to apply a multistep framework closely akin to American Express’s. As its first step, the district courtrequired the student-athletes to show that “the challenged restraints produce significant anticompetitive effects in the relevant market.” D. Ct. Op., at 1067. This was no slight burden. According to one amicus, courts have disposed ofnearly all rule of reason cases in the last 45 years on the ground that the plaintiff failed to show a substantial anticompetitive effect. Brief for 65 Professors of Law, Business, Economics, and Sports Management as Amici Curiae 21,
n. 9 (“Since 1977, courts decided 90% (809 of 897) on this ground”). This suit proved different. As we have seen,
based on a voluminous record, the district court held that the student-athletes had shown the NCAA enjoys the power to set wages in the market for student-athletes’ labor—and that the NCAA has exercised that power in ways that haveproduced significant anticompetitive effects. See D. Ct. Op., at 1067. Perhaps even more notably, the NCAA “did not meaningfully dispute” this conclusion. Ibid.

Unlike so many cases, then, the district court proceeded to the second step, asking whether the NCAA could mustera procompetitive rationale for its restraints. Id., at 1070. This is where the NCAA claims error first crept in. On its account, the district court examined the challenged rules atdifferent levels of generality. At the first step of its inquiry,the court asked whether the NCAA’s entire package of compensation restrictions has substantial anticompetitive effects collectively. Yet, at the second step, the NCAA saysthe district court required it to show that each of its distinctrules limiting student-athlete compensation has procompetitive benefits individually. The NCAA says this mismatch had the result of effectively—and erroneously—requiring it to prove that each rule is the least restrictive means of achieving the procompetitive purpose of differentiating college sports and preserving demand for them.

We agree with the NCAA’s premise that antitrust law does not require businesses to use anything like the least restrictive means of achieving legitimate business purposes. To the contrary, courts should not second-guess “degrees of reasonable necessity” so that “the lawfulness of conduct turn[s] upon judgments of degrees of efficiency.” Rothery Storage, 792 F. 2d, at 227; Continental T. V., Inc. v. GTE Sylvania Inc., 433 U. S. 36, 58, n. 29 (1977). That would be a recipe for disaster, for a “skilled lawyer” will“have little difficulty imagining possible less restrictive alternatives to most joint arrangements.” 11 Areeda & Hovenkamp ¶1913b, p. 398 (2018). And judicial acceptance of such imaginings would risk interfering “with the legitimate objectives at issue” without “adding that much to competition.” 7 id., ¶1505b, at 435–436.

Even worse, “[r]ules that seek to embody every economic complexity and qualification may well, through the vagaries of administration, prove counter-productive, undercutting the very economic ends they seek to serve.” Barry Wright Corp. v. ITT Grinnell Corp., 724 F. 2d 227, 234 (CA1 1983) (BREYER, J.). After all, even “[u]nder the best of circumstances,” applying the antitrust laws “‘can be difficult’”—and mistaken condemnations of legitimate business arrangements “‘are especially costly, because they chill thevery’” procompetitive conduct “‘the antitrust laws are designed to protect.’” Verizon Communications Inc. v. Law Offices of Curtis V. Trinko, LLP, 540 U. S. 398, 414 (2004). Indeed, static judicial decrees in ever-evolving markets may themselves facilitate collusion or frustrate entry and competition. Ibid. To know that the Sherman Act prohibits only unreasonable restraints of trade is thus to know that attempts to “‘[m]ete[r]’ small deviations is not an appropriate antitrust function.” Hovenkamp, Antitrust Balancing,12 N. Y. U. J. L. & Bus. 369, 377 (2016).

While we agree with the NCAA’s legal premise, we cannot say the same for its factual one. Yes, at the first step of its inquiry, the district court held that the student-athletes had met their burden of showing the NCAA’s restraints collectively bear an anticompetitive effect. And, given that,yes, at step two the NCAA had to show only that those same rules collectively yield a procompetitive benefit. The trouble for the NCAA, though, is not the level of generality. It is the fact that the district court found unpersuasive muchof its proffered evidence. See D. Ct. Op., at 1070–1076,1080–1083. Recall that the court found the NCAA failed “to establish that the challenged compensation rules . . . have any direct connection to consumer demand.” Id., at 1070.

To be sure, there is a wrinkle here. While finding the NCAA had failed to establish that its rules collectively sustain consumer demand, the court did find that “some” of those rules “may” have procompetitive effects “to the extent” they prohibit compensation “unrelated to education, akin to salaries seen in professional sports leagues.” Id., at 1082–1083. The court then proceeded to what correspondsto the third step of the American Express framework, where it required the student-athletes “to show that there are substantially less restrictive alternative rules that wouldachieve the same procompetitive effect as the challengedset of rules.” D. Ct. Op., at 1104. And there, of course, the district court held that the student-athletes partially succeeded—they were able to show that the NCAA could achieve the procompetitive benefits it had established with substantially less restrictive restraints on education-related benefits.

Even acknowledging this wrinkle, we see nothing about the district court’s analysis that offends the legal principlesthe NCAA invokes. The court’s judgment ultimately turnedon the key question at the third step: whether the student-athletes could prove that “substantially less restrictive alternative rules” existed to achieve the same procompetitivebenefits the NCAA had proven at the second step. Ibid. Of course, deficiencies in the NCAA’s proof of procompetitivebenefits at the second step influenced the analysis at the third. But that is only because, however framed and at whichever step, anticompetitive restraints of trade maywind up flunking the rule of reason to the extent the evidence shows that substantially less restrictive means exist to achieve any proven procompetitive benefits. See, e.g., 7 Areeda & Hovenkamp ¶1505, p. 428 (“To be sure, these two questions can be collapsed into one,” since a “legitimate objective that is not promoted by the challenged restraint canbe equally served by simply abandoning the restraint, which is surely a less restrictive alternative”).

Simply put, the district court nowhere—expressly or effectively—required the NCAA to show that its rules constituted the least restrictive means of preserving consumer demand. Rather, it was only after finding the NCAA’srestraints “‘patently and inexplicably stricter than is necessary’” to achieve the procompetitive benefits the league had demonstrated that the district court proceeded to declare a violation of the Sherman Act. D. Ct. Op., at 1104. That demanding standard hardly presages a future filled with judicial micromanagement of legitimate business decisions.

B In a related critique, the NCAA contends the district court “impermissibly redefined” its “product” by rejectingits views about what amateurism requires and replacing them with its preferred conception. Brief for Petitioner in No. 20–512, at 35–36. This argument, however, misapprehends the way a defendant’s procompetitive business justification relates tothe antitrust laws. Firms deserve substantial latitude to fashion agreements that serve legitimate business interests—agreements that may include efforts aimed at introducing a new product into the marketplace. Supra, at 15– 19.

But none of that means a party can relabel a restraint as a product feature and declare it “immune from §1 scrutiny.” American Needle, 560 U. S., at 199, n. 7. In this suit, as in any, the district court had to determine whether the defendants’ agreements harmed competition and whether any procompetitive benefits associated with their restraintscould be achieved by “substantially less restrictive alternative” means. D. Ct. Op., at 1104.

The NCAA’s argument not only misapprehends the inquiry, it would require us to overturn the district court’s factual findings. While the NCAA asks us to defer to its conception of amateurism, the district court found that the NCAA had not adopted any consistent definition. Id., at 1070. Instead, the court found, the NCAA’s rules and restrictions on compensation have shifted markedly overtime. Id., at 1071–1074. The court found, too, that the NCAA adopted these restrictions without any reference to“considerations of consumer demand,” id., at 1100, and that some were “not necessary to preserve consumer demand,” id., at 1075, 1080, 1104. None of this is product redesign; itis a straightforward application of the rule of reason.

C Finally, the NCAA attacks as “indefensible” the lower courts’ holding that substantially less restrictive alternatives exist capable of delivering the same procompetitivebenefits as its current rules. Brief for Petitioner in No. 20– 512, at 46. The NCAA claims, too, that the district court’s injunction threatens to “micromanage” its business. Id., at 50. Once more, we broadly agree with the legal principles theNCAA invokes. As we have discussed, antitrust courts must give wide berth to business judgments before finding liability. See supra, at 15–19. Similar considerations applywhen it comes to the remedy. Judges must be sensitive tothe possibility that the “continuing supervision of a highly detailed decree” could wind up impairing rather than enhancing competition. Trinko, 540 U. S., at 415. Costs associated with ensuring compliance with judicial decrees mayexceed efficiencies gained; the decrees themselves may unintentionally suppress procompetitive innovation and even facilitate collusion. See supra, at 26–27. Judges must bewary, too, of the temptation to specify “the proper price,quantity, and other terms of dealing”—cognizant that they are neither economic nor industry experts. Trinko, 540
U. S., at 408. Judges must be open to reconsideration and modification of decrees in light of changing market realities, for “what we see may vary over time.” California Dental, 526 U. S., at 781. And throughout courts must have a healthy respect for the practical limits of judicial administration: “An antitrust court is unlikely to be an effective day-to-day enforcer” of a detailed decree, able to keep pacewith changing market dynamics alongside a busy docket. Trinko, 540 U. S., at 415. Nor should any court “‘impose a duty . . . that it cannot explain or adequately and reasonably supervise.’” Ibid. In short, judges make for poor “central planners” and should never aspire to the role. Id., at 408.

Once again, though, we think the district court honoredthese principles. The court enjoined only restraints on ed-ucation-related benefits—such as those limiting scholarships for graduate school, payments for tutoring, and thelike. The court did so, moreover, only after finding that relaxing these restrictions would not blur the distinction between college and professional sports and thus impair demand—and only after finding that this course represented a significantly (not marginally) less restrictive means ofachieving the same procompetitive benefits as the NCAA’scurrent rules. D. Ct. Op., at 1104–1105.

Even with respect to education-related benefits, the district court extended the NCAA considerable leeway. As we have seen, the court provided that the NCAA could develop its own definition of benefits that relate to education and seek modification of the court’s injunction to reflect thatdefinition. App. to Pet. for Cert. in No. 20–512, at 168a, ¶4.The court explained that the NCAA and its members could agree on rules regulating how conferences and schools go about providing these education-related benefits. Ibid. The court said that the NCAA and its members could continue fixing education-related cash awards, too—so long as those“limits are never lower than the limit” on awards for athletic performance. D. Ct. Op., at 1104; App. to Pet. for Cert. in No. 20–512, at 168a–169a, ¶5. And the court emphasized that its injunction applies only to the NCAA and multiconference agreements; individual conferences remain free toreimpose every single enjoined restraint tomorrow—or more restrictive ones still. Id., at 169a–170a, ¶¶6–7.

In the end, it turns out that the NCAA’s complaints reallyboil down to three principal objections.
First, the NCAA worries about the district court’s inclusion of paid posteligibility internships among the education-related benefits it approved. The NCAA fears that schools will use internships as a way of circumventing limits on payments that student-athletes may receive for athletic performance. The NCAA even imagines that boosters might promise posteligibility internships “at a sneaker company or auto dealership” with extravagant salaries as a “thinly disguised vehicle” for paying professional-level salaries. Brief for Petitioner in No. 20–512, at 37–38.
This argument rests on an overly broad reading of the injunction. The district court enjoined only restrictions oneducation-related compensation or benefits “that may bemade available from conferences or schools.” App. to Pet. for Cert. in No. 20–512, at 167a, ¶1 (emphasis added). Accordingly, as the student-athletes concede, the injunction“does not stop the NCAA from continuing to prohibit compensation from” sneaker companies, auto dealerships,boosters, “or anyone else.” Brief for Respondents 47–48; seealso Brief for United States as Amicus Curiae 33. The NCAA itself seems to understand this much. Following thedistrict court’s injunction, the organization adopted new regulations specifying that only “a conference or institution” may fund post-eligibility internships. See Decl. of M. Boyer in No. 4:14–md–02541, ECF Doc. 1302–2, p. 6 (ND Cal., Sept. 22, 2020) (NCAA Bylaw 16.3.4(d)).

Even when it comes to internships offered by conferences and schools, the district court left the NCAA considerable flexibility. The court refused to enjoin NCAA rules prohibiting its members from providing compensation or benefits unrelated to legitimate educational activities—thus leaving the league room to police phony internships. As we’ve observed, the district court also allowed the NCAA to propose (and enforce) rules defining what benefits do and do not relate to education. App. to Pet. for Cert. in No. 20–512, at 168a, ¶4. Accordingly, the NCAA may seek whatever limits on paid internships it thinks appropriate. And, again, the court stressed that individual conferences may restrict internships however they wish. Id., at 169a, ¶6. All these features underscore the modesty of the current decree.

Second, the NCAA attacks the district court’s ruling thatit may fix the aggregate limit on awards schools may give for “academic or graduation” achievement no lower than itsaggregate limit on parallel athletic awards (currently$5,980 per year). Id., at 168a–169a, ¶5; D. Ct. Op., at 1104. This, the NCAA asserts, “is the very definition of a professional salary.” Brief for Petitioner in No. 20–512, at 48. The NCAA also represents that “[m]ost” of its currently permissible athletic awards are “for genuine individual or team achievement” and that “[m]ost . . . are received by only a few student-athletes each year.” Ibid. Meanwhile, the NCAA says, the district court’s decree would allow a school to pay players thousands of dollars each year for minimal achievements like maintaining a passing GPA. Ibid.

The basis for this critique is unclear. The NCAA does not believe that the athletic awards it presently allows are tantamount to a professional salary. And this portion of the injunction sprang directly from the district court’s findingthat the cap on athletic participation awards “is an amount that has been shown not to decrease consumer demand.” D. Ct. Op., at 1088. Indeed, there was no evidence before the district court suggesting that corresponding academicawards would impair consumer interest in any way. Again, too, the district court’s injunction affords the NCAA leeway.It leaves the NCAA free to reduce its athletic awards. And it does not ordain what criteria schools must use for their academic and graduation awards. So, once more, if the NCAA believes certain criteria are needed to ensure that academic awards are legitimately related to education, it is presently free to propose such rules—and individual conferences may adopt even stricter ones.

Third, the NCAA contends that allowing schools to provide in-kind educational benefits will pose a problem. This relief focuses on allowing schools to offer scholarships for“graduate degrees” or “vocational school” and to pay for things like “computers” and “tutoring.” App. to Pet. forCert. in No. 20–512, at 167a–168a, ¶2. But the NCAA fears schools might exploit this authority to give student-athletes“‘luxury cars’” “to get to class” and “other unnecessary orinordinately valuable items” only “nominally” related to education. Brief for Petitioner in No. 20–512, at 48–49.

Again, however, this over-reads the injunction in ways wehave seen and need not belabor. Under the current decree, the NCAA is free to forbid in-kind benefits unrelated to a student’s actual education; nothing stops it from enforcing a “no Lamborghini” rule. And, again, the district court invited the NCAA to specify and later enforce rules delineating which benefits it considers legitimately related to education. To the extent the NCAA believes meaningfulambiguity really exists about the scope of its authority—regarding internships, academic awards, in-kind benefits, or anything else—it has been free to seek clarification from the district court since the court issued its injunction three years ago. The NCAA remains free to do so today. To date, the NCAA has sought clarification only once—about the precise amount at which it can cap academic awards—andthe question was quickly resolved. Before conjuring hypothetical concerns in this Court, we believe it best for the NCAA to present any practically important question it hasin district court first.

When it comes to fashioning an antitrust remedy, weacknowledge that caution is key. Judges must resist the temptation to require that enterprises employ the least restrictive means of achieving their legitimate business objectives. Judges must be mindful, too, of their limitations—as generalists, as lawyers, and as outsiders trying to understand intricate business relationships. Judges must remain aware that markets are often more effective than the heavy hand of judicial power when it comes to enhancingconsumer welfare. And judges must be open to clarifying and reconsidering their decrees in light of changing marketrealities. Courts reviewing complex business arrangements should, in other words, be wary about invitations to“set sail on a sea of doubt.” United States v. Addyston Pipe & Steel Co., 85 F. 271, 284 (CA6 1898) (Taft, J.). But we do not believe the district court fell prey to that temptation.Its judgment does not float on a sea of doubt but stands onfirm ground—an exhaustive factual record, a thoughtful legal analysis consistent with established antitrust principles, and a healthy dose of judicial humility.

* Some will think the district court did not go far enough. By permitting colleges and universities to offer enhanced education-related benefits, its decision may encourage scholastic achievement and allow student-athletes a measure of compensation more consistent with the value they bring to their schools. Still, some will see this as a poor substitute for fuller relief. At the same time, others will think the district court went too far by undervaluing the social benefits associated with amateur athletics. For our part, though, we can only agree with the Ninth Circuit:“‘The national debate about amateurism in college sports is important. But our task as appellate judges is not to resolve it. Nor could we. Our task is simply to review the districtcourt judgment through the appropriate lens of antitrust law.’” 958 F. 3d, at 1265. That review persuades us the district court acted within the law’s bounds.”
