Authors

2025 marked a period of profound transformation across the sports and gaming industries. From the explosive growth of prediction markets and robust integrity enforcement in sports betting to record-setting franchise acquisitions and name, image, and likeness (NIL) deals, the industry saw trends from prior years accelerate. Legal developments—including antitrust litigation and shifting regulatory frameworks—promise to reshape the relationships between leagues, athletes and investors. Meanwhile, US sports leagues continue to focus on growing international engagement and opportunity. This article examines the top five developments that defined sports and gaming in 2025, analyzing the forces driving change and the implications for stakeholders, who must navigate an increasingly complex and dynamic landscape.

Prediction Markets and Sports-Based Event Contracts 

Prediction markets are exchanges where participants buy and trade contracts reflecting the outcome of real-world events (event contracts)—from election results1 to sports games2 and more niche questions, such as whether a super volcano will erupt before 2050and who will play the next James Bond.4 Event contracts are generally understood to be a form of derivative, typically structured with a binary payoff that depends on the outcome of an underlying event. Although the Commodity Futures Trading Commission (CFTC) has regulated prediction markets and similar exchanges for decades,5 in recent years, the contracts offered on prediction markets have changed dramatically, and the popularity of sports-related event contracts exploded in 2025.

In 2025, trading activity for sports-related event contracts reached unprecedented levels. Reports indicated that the two leading exchanges—Kalshi and Polymarket—collectively recorded more than $6 billion in weekly trading volume.6 At the same time, several major gaming companies entered, or began actively exploring, prediction markets as a new frontier. In 2025, prominent entities in the sports and gaming industries—including DraftKings, Underdog,7 FanDuel, Fanatics8 and Sports Illustrated9—announced plans to launch their own prediction market platforms, while major media and technology platforms such as X,10 Yahoo Finance,11 CNN12 and Google13 began integrating real‑time data from existing exchanges into their products and user experiences.

Despite their rapid growth and increasing mainstream acceptance, sports-related event contracts face significant legal uncertainty.  Since the US Supreme Court ruled in Murphy v. NCAA that states could legalize and regulate sports betting,14 individuals could place sports wagers only in states that affirmatively legalized online sports betting and only with licensed sportsbooks. As a result, sports-related wagers fell outside the purview of the CFTC and under the purview of the states. Recently, however, prediction market platforms introduced nationwide access to wager‑like trading on sports outcomes, even in states where online sports betting is not legal, a move spurred by a 2024 decision from the US Court of Appeals for the District of Columbia permitting Kalshi to offer event contracts tied to the outcome of the November 2024 congressional elections on its CFTC‑regulated platform.15

The introduction of sports-related event contracts has effectively shifted an activity typically governed by state law—sports-related wagering—into the federal domain.16 Under the Trump Administration, the CFTC acceded to the notion that all event contracts fall within the exclusive purview of the Commodity Exchange Act (CEA).17 Conversely, state18 and tribal authorities,19 which have traditionally overseen sports betting in their jurisdictions, increasingly classify sports-related event contracts as gaming subject to state or tribal gaming regulations. These divergent views—of states and tribes on one hand, and of the CFTC on the other—have fueled a wave of litigation in state and federal courts.20 Meanwhile, federal courts issued conflicting rulings as to whether sports-related event contracts fall within the purview of state anti-gaming laws21 or are preempted by the CEA.22

Without consistent guidance from courts or regulators, prediction market operators must navigate a patchwork of conflicting obligations rife with compliance risk and potential exposure to civil and criminal penalties at the state level. Although CFTC Chairman Michael Selig stated in January 2026 that the CFTC intends to regulate prediction markets under the CEA,23 state-level litigation and resistance persist, underscoring that courts may ultimately determine the allocation of regulatory authority over prediction markets.24

US Courts of Appeals for the Third, Fourth and Ninth Circuits are considering whether the CEA preempts state anti-gaming laws.25 While the circuit courts’ decisions may bring short-term clarity, the potential for conflicting decisions—absent an ultimate resolution by the US Supreme Court—threatens to prolong regulatory uncertainty. Nonetheless, if the ultimate judicial determination is that the CEA does preempt state laws purporting to regulate sports-related event contracts, states would have to cede authority over those event contracts to the CFTC. Conversely, if the US Supreme Court determines the CEA does not preempt state gaming laws, prediction market operators would have to traverse a complex regulatory landscape, rife with differing state laws that platforms claim would threaten their ability to maintain a “single nationwide market.”26 Ultimately, however, these appeals signal that the judiciary is likely to determine whether sports-related event‑contract markets gain long‑sought clarity or remain subject to a divided and burdensome compliance landscape.

Notably, in January 2026, the CFTC expressed its intention to regulate prediction markets exclusively and to allow sports-related event contracts to be traded on CFTC-backed exchanges.27 Chairman Selig directed the CFTC to withdraw Biden-era proposals to “prohibit political and sports-related event contracts” on CFTC-regulated exchanges; to “move forward with drafting an event contracts rulemaking”; to “reassess the [CFTC’s] participation in matters pending before the federal district and circuit courts”; and to “defend [the CFTC’s] exclusive jurisdiction” (i.e., federal preemption) “over commodity derivatives” in court.28 Accordingly, prediction market operators now have an important ally—the CFTC—as they seek to defeat challenges from states, tribes and private entities over sports-related and other event contracts. Nevertheless, clarity may not arrive unless the appellate courts—and ultimately the US Supreme Court—weigh in.

Integrity Issues and Sports Betting 

Although integrity concerns in sports betting are long-standing, recent enforcement actions highlight the risks related to the proliferation of legalized sports betting.29 In 2025, several NBA players and coaches were charged with conspiracy to commit wire fraud and money laundering for allegedly using insider information to win bets,30 and Toronto Raptors player Jontay Porter pleaded guilty to conspiracy to commit wire fraud for doing the same.31 Meanwhile, MLB pitchers Emmanuel Clase and Luis Ortiz pleaded not guilty to conspiracy charges for allegedly rigging player position bets related to their pitching.32

The House and Senate have taken notice of the high-profile investigations. On the heels of the Ortiz and Clase indictments,33 the US Senate Committee on Commerce, Science, and Transportation sent inquiries to MLB in November 2025 requesting information “on allegations of gambling corruption in the league.”34 Similarly, in October 2025, the House Committee on Energy and Commerce sent an inquiry to the NBA following a federal investigation into an illegal betting ring35 and a letter to NCAA President Charlie Baker regarding the NCAA’s announcement that athletes and staff will be allowed to bet on professional sports.36

Proposition bets (prop bets)—wagers on specific in-game events (e.g., whether a player will score or a quarterback will throw an interception)—are a common source of integrity violations, in part because players can personally influence specific occurrences. Some leagues, including MLB,37 the NBA38 and the NFL39 have worked with sportsbooks to curb unlawful prop bets and to reduce or eliminate the availability of bets that are uniquely susceptible to manipulation.40 And legislators in several states—citing “a torrent of controversies related to match fixing in professional and collegiate sports”—have introduced legislation seeking to ban in-game prop betting.41 Because prop bets are highly profitable—and even considered by some to be the “backbone” of popular wagers42—sportsbooks, leagues and states are incentivized to prevent manipulation.

Although it is impossible to stop all illegal activity, coordination between leagues, teams, sportsbooks and law enforcement—facilitated by the increased regulation of sports betting—has markedly improved the ability to detect illegal activity.43 “[R]egulated sportsbooks are proving to be effective watchdogs,” not instruments that undermine fair play, in part because “[t]heir data-driven insights and compliance protocols are helping uncover misconduct that would have otherwise remained buried.”44 Compliance measures like Know Your Customer protocols and anti-money laundering laws help uncover misconduct, unlike “illegal betting markets [which] lack oversight” and are therefore “fertile ground for corruption.”45 Indeed, illegal betting has dropped sharply—from between $149 billion and $500 billion in 2017 to $63.8 billion in 202346—reflecting the success and draw of legal frameworks. With leagues, sportsbooks and states benefiting from betting revenue,47 key stakeholders have a vested interest in integrity, which remains critical; fans will only watch—and bet on—sports if they trust the games are fair.

Franchise Acquisitions and Private Capital Investment in Sports

In 2025, the sports industry cemented its status as a premier investment sector. 2025 saw record-high valuations and landmark franchise sales, including the sales of the Los Angeles Lakers48 and the Boston Celtics,49 and the acquisition of shares by institutional investors in marquee franchises like the San Francisco Giants,50 the New England Patriots51 and the New York Giants.52 The influx of institutional capital is substantial; today, nearly 20% of teams across the four major men’s US professional sports leagues (NFL, NBA, MLB and NHL) have some level of private equity involvement.53 This growth also reached emerging organizations and women’s professional sports leagues, such as the NWSL and WNBA,54 which increasingly leverage private lenders and institutional capital to fuel rapid expansion, driven by their own record valuations.

Professional sports leagues draw major investment for a variety of reasons. In particular, their closed‑system structure—characterized by revenue sharing, player drafts and salary caps—helps ensure predictable long‑term costs and stable cash flow, reinforced by diversified revenue sources (e.g., multiyear media rights agreements, corporate sponsorships and in-venue revenue). Investors are also drawn to sports franchises because of their ability to monetize real estate assets, using stadiums for large-scale, mixed-use developments that integrate hospitality, retail and residential components and to host community development projects. Similarly, international expansion and the adaptive nature of franchises’ business models (e.g., the ability to generate revenue through hospitality, content creation and data analytics) have also driven institutional investments.

Private investment activity also flourished for collegiate athletics, as universities and conferences explored new financial models to fund operations, facilities and sponsorships in the NIL era. The Big Ten Conference is negotiating a $2.4 billion proposal with UC Investments for a 10% stake in future media rights and sponsorships through 2046 in exchange for an immediate cash infusion to its 18 member schools,55 and the University of Utah is finalizing a landmark partnership with Otro Capital to create a for-profit, distinct entity projected to generate an estimated $500 million for the school.56

Nevertheless, collegiate athletics will likely face governance challenges throughout 2026 as schools navigate how to weigh private credit deals against fiduciary duties. Several schools have publicly noted the risks associated with complex private credit proposals, such as long-term value erosion, inflexibility and governance deficiencies.57 Others have acknowledged the risk of friction if the venture fails to generate expected revenue and the inherent tension between commercial success and the university’s mission, even claiming the school could veto any sponsorship opportunity at odds with its values.58

The distinct structural and economic characteristics of professional sports leagues will likely continue to fuel transactional activity throughout 2026, which will necessarily heighten litigation and governance risk. Private equity investments may trigger regulatory scrutiny and disputes centering on governance structure, control provisions, fiduciary duties, valuation methodologies and revenue-sharing arrangements. And the prevalence of minority investments promises to create fertile ground for stakeholder friction.59 Consequently, teams should implement robust governance frameworks and comprehensive operating agreements that clearly define decision-making authority, information rights and the processes governing major capital expenditures.  Doing so will help ensure clarity regarding authority over decisions impacting profits and valuations—a uniquely important determination for sports franchises, whose on-the-field success directly impacts revenue and valuation.

The Growing Conflict Between Sports and Antitrust Laws 

In 2025, collegiate and professional sports saw antitrust challenges over NIL rights, revenue sharing and market control—developments that could dismantle traditional regulations and usher in a new era for sports businesses. These cases highlight a clear theme: Antitrust law is a useful mechanism for redefining economic relationships in sports. Indeed, without comprehensive legislation from Congress, athletes and teams are increasingly turning to litigation to assert competition rights, pressuring traditional league models to evolve.

In 2021, the US Supreme Court ruled in In re College Athlete NIL Litigation60 that NCAA restrictions on athlete compensation violated Section I of the Sherman Act, uprooting the history of amateurism that had long been the hallmark of collegiate athletics. The parties reached a $2.8 billion settlement in 2024,61 which was approved by Judge Claudia Wilken in June 202562 but is the subject of three Title IX appeals before the US Court of Appeals for the Ninth Circuit.63

The ruling that NCAA athletes are eligible for compensation exemplifies the need for a new legal regime to govern collegiate athletics. But recent legislation, including the Student Compensation and Opportunity through Rights and Endorsements Act (SCORE Act)—which was designed to address athletes’ compensation, clarify that NCAA athletes are not employees and provide the NCAA with antitrust immunity64—has stalled.65 This may signal a shift in Congress’s views regarding antitrust protections and caution among lawmakers around expanding antitrust exemptions—a posture that may increase scrutiny of practices that limit competition.

Mounting antitrust pressure on NASCAR, for example, highlights growing scrutiny of how major sports organizations wield market power. In October 2024, 23Xl Racing—owned by NBA superstar Michael Jordan—and Front Row Motorsports sued NASCAR, claiming NASCAR’s control of the racing market violated the Sherman Act.66 The dispute centered on NASCAR’s charter agreement, which plaintiffs claimed functionally forced teams to sign unfair terms to avoid “economically devastating” consequences and which prohibited participation in “automobile or truck racing” outside NASCAR events.67 Although the parties reached a settlement agreement in December 2025,68 this controversy illustrates a potential transformation in NASCAR’s approach to its traditional business model and the strength of athletes’ demands for fairness; plaintiffs lauded the settlement as evidence of “progress.”69

Furthermore, recent lawsuits against professional tennis organizations exemplify the escalating clash between sports leagues and antitrust law. In March 2025, the Professional Tennis Players Association and numerous athletes sued professional tennis organizations70 and organizers of the Grand Slam events, alleging violations of the Sherman Act, related in part to player compensation, competition, NIL rights and sponsorship restrictions.71 This case underscores the movement toward safeguarding athletes’ economic rights and could significantly reshape how professional tennis and other sports organizations operate.

In short, the sports industry is recalibrating as athletes increasingly challenge entrenched governance and economic arrangements through litigation. In both professional and collegiate sports, these disputes reflect growing pressure on traditional power dynamics. Although 2025 did not conclusively determine how changes to athletes’ economic rights will ultimately play out, it did move the needle one step further in athletes’ favor.

Growth of US Sports Abroad 

2025 may have marked an inflection point in the outward expansion of America’s major leagues, with the NFL, the NBA and MLB all staging high‑profile events outside US borders and, in some cases, committing to multiyear footholds in new markets.72

In 2025, the NFL expanded its international reach, scheduling a record seven regular-season international games in five countries: Brazil, Ireland, Germany, Spain and the United Kingdom. Madrid and Berlin hosted their first-ever NFL games that year,73 and NFL Commissioner Roger Goodell reiterated that the league plans to increase the number of international games such that each team will play one game abroad each year.74 The NFL has separately sought to grow its international fan base by “expand[ing] its Global Markets Program, which awards teams international marketing rights to build brand awareness and fandom beyond the United States”; “[n]ow[,] all 32 teams participate in the program across 21 international markets”—a substantial increase from 2019, when only 25 clubs participated across 19 markets.75

The NBA likewise sought to grow its international presence.  It broadened its calendar of overseas showcases76 and has stated it plans to host “preseason games in China and Europe.”77 The NBA is also eyeing an expansion in Europe and Asia and has had conversations with investors and partners about creating an “NBA-backed European league.”78

MLB has similarly expanded its international reach. In 2025, for the first time in MLB history, the regular season began and ended outside the United States,79 as MLB opted to host these “season-defining events” abroad80—a move driven by profitable international TV details and fan demand.81 Notably, globalization proved lucrative; in 2024, for instance, viewership, jersey and apparel sales, and sponsorships abroad grew substantially.82 Indeed, when Shohei Ohtani, a Japanese-born pitcher for the Los Angeles Dodgers, won his third MVP award in 2024, the Dodgers received an influx of Japanese sponsors, netting the team $100 million in one year.83

This international growth is accompanied by a rapidly evolving international media ecosystem. Streaming services will be integral to distributing games abroad, and spending on streaming rights has ballooned in recent years, with one estimate projecting that streaming services will account for $12.5 billion in sports-rights expenditure in 2025.84 Relatedly, media spending on streaming rights to live sports in the US surged to roughly $30 billion in 2025, reflecting the premium value of live sports.85 Recently, the NBA reached a multiyear deal with Tencent, a Chinese digital media company, allowing Tencent to stream NBA games in China through 2027.86 The deal suggests that the NBA’s interest in China—long a top overseas market87—has regained momentum and signals the willingness of American leagues to expand globally—a posture bolstered by the NBA’s 2025 decision to host its first games in China since 2019. As various leagues seek to expand their reach abroad and as cross‑border distribution becomes increasingly reliant on streaming services, each league will have to navigate complex rights architectures in foreign countries.

Labor, immigration and commercial restrictions also loom large as US-based leagues seek to expand internationally. Player and staff visa logistics and taxation, for example, vary by host country. Sponsorship and ownership trends—particularly private equity and potential sovereign capital—raise governance issues and, in certain regions, risk exposure to sanctions and Foreign Corrupt Practices Act and/or UK Bribery Act liability over such investments. Meanwhile, antitrust scrutiny is intensifying, a theme that may continue to arise as US sports seek expansion into international markets, often with different—and stricter—antitrust laws.

The international expansion of American sports leagues in 2025 marks a pivotal shift in the global sports landscape. As American leagues continue to build their brands and operations worldwide, their success will depend on navigating diverse legal frameworks—ensuring that the promise of global growth is matched by careful compliance and adaptive strategy.

Conclusion

The changes of 2025 have positioned 2026 as a pivotal year for the sports industry. Courts and regulators may finally decide whether sports‑related event contracts fall under state anti‑gaming laws or the CEA—a determination that could reset the sports wagering landscape. Pressure to curb manipulation may drive limits on prop bets, while private equity investment, Title IX appeals and athlete‑compensation cases could reshape governance and collegiate sports obligations. And as US leagues push abroad, new opportunities for growth are likely to emerge, while challenges, related primarily to streaming rights and foreign regulations, may confront stakeholders in new environments. Ultimately, 2026 is poised to clarify unsettled areas and open new paths for strategic growth.
