The Lawsuit: Allegations of Monopolization and Anticompetitive Conditions
In October 2024, 23XI Racing and Front Row Motorsports filed suit in the Western District of North Carolina, alleging violations of Sections 1 and 2 of the Sherman Act.¹ The plaintiffs assert that NASCAR functions as a monopolist in the market for top-tier stock car racing in the United States. They allege that NASCAR exercises vertically integrated control over essential components of the sport, including sanctioning authority, scheduling, rulemaking, track ownership, media rights, and entry credentials.
Central to the complaint is the charter system NASCAR implemented in 2016. Charters confer guaranteed entry into each Cup Series race and provide a steady share of revenue. According to the plaintiffs, NASCAR required teams to sign a release of all existing and future antitrust claims as a condition of participation in the 2025 charter season. 23XI and Front Row refused to execute the release and, in turn, sought legal redress to preserve their charter participation while contesting the legality of that condition.²
Injunctive Relief: Initial Victory in the District Court
The plaintiffs moved for a preliminary injunction to enjoin NASCAR from excluding them from charter status due to their refusal to sign the release. In December 2024, District Judge Kenneth D. Bell granted the injunction, finding that the plaintiffs demonstrated a likelihood of success on the merits of their monopolization claim—specifically regarding the coercive nature of the release clause.³
Judge Bell concluded that conditioning a team’s ability to participate in the charter system—a core economic structure of NASCAR’s premier series—on the waiver of current and future antitrust claims potentially constituted exclusionary conduct under Section 2 of the Sherman Act. In his view, NASCAR’s use of its market power to compel legal surrender in exchange for continued economic viability raised serious concerns about coercive monopolistic practices. The court emphasized that such a condition could insulate NASCAR from meaningful legal accountability while simultaneously denying rival teams fair access to the economic and competitive benefits that come with charter status.
In granting the preliminary injunction, Judge Bell also found that the plaintiffs faced irreparable harm absent immediate relief. This harm was not merely speculative: exclusion from the charter system threatened to disrupt long-term sponsorship agreements, undermine contractual relationships with drivers and staff, and eliminate the stability of guaranteed race entry and revenue. These consequences, the court reasoned, would be difficult to quantify or redress after the fact, satisfying the threshold for irreparable harm. Moreover, the court found that the balance of equities and the public interest tipped decisively in favor of maintaining the status quo. Preserving the plaintiffs’ ability to compete while the litigation proceeds was essential to preventing irreversible market distortion and ensuring that antitrust claims could be adjudicated on the merits without undue leverage exerted by the (alleged) dominant market actor.
The Appeal: Fourth Circuit Reverses the Injunction
On appeal, the Fourth Circuit Court of Appeals vacated the preliminary injunction in June 2025, concluding that the district court abused its discretion by granting relief based on a legal theory unsupported by precedent.⁵ Writing for a unanimous panel, the appeals court reasoned that the plaintiffs failed to show a likelihood of success on the merits because the mere requirement to sign a release of antitrust claims—as a contractual condition—does not, standing alone, establish monopolistic conduct.
The court emphasized that preliminary injunctions are extraordinary remedies, and that speculative or novel legal theories, without firm grounding in existing antitrust doctrine, cannot support the issuance of equitable relief. Accordingly, the injunction was vacated, restoring NASCAR’s discretion to enforce its charter eligibility requirements.⁶
Practical Consequences: Racing Without a Charter
The immediate consequence of the appellate ruling was that 23XI Racing and Front Row Motorsports were relegated to “open team” status in the NASCAR Cup Series. Without charters, these teams no longer enjoy guaranteed entry into races, and instead must qualify on the basis of performance each week.⁷ This status also significantly diminishes their revenue potential, marketing certainty, and long-term team planning. Nevertheless, both organizations have continued to compete in Cup Series races through strong qualifying results and operational resilience.⁸
Although the reversal represents a procedural victory for NASCAR, it does not resolve the underlying merits of the case. The plaintiffs are still actively pursuing their antitrust claims in the district court, and have also filed a petition for rehearing en banc in the Fourth Circuit, seeking to reinstate the injunction.⁹
What Lies Ahead: Trial and Potential Market Impacts
The case is currently scheduled for trial on December 1, 2025.¹⁰ If the plaintiffs ultimately prevail, the litigation could force material changes in how NASCAR structures its economic model and contracts with race teams. A favorable ruling could also open the door to substantial treble damages under Section 4 of the Clayton Act. Conversely, a defense verdict could solidify NASCAR’s autonomy in designing governance mechanisms for professional motorsports—potentially insulating other league-style organizations from similar challenges.
Beyond its immediate implications, this case may help shape the application of antitrust principles to non-traditional, privately managed sports enterprises that function as both regulators and participants in the markets they dominate. The outcome could affect not only motorsports but also esports, entertainment leagues, and other hybrid commercial ecosystems. Indeed, many leagues operate franchise or membership systems—similar to NASCAR’s charter model—where entry rights carry substantial economic value. A ruling against NASCAR could limit the ability of such organizations to impose restrictive contractual terms, like waivers of antitrust claims, as conditions of participation. This could invite challenges to “take-it-or-leave-it” agreements, exclusive participation rules, and vertically integrated control of media rights and sponsorships.
Conclusion
The case of 23XI Racing v. NASCAR reflects the increasing tension between monopoly power in sports governance and the evolving expectations of legal accountability under antitrust law. As the case moves toward trial, its outcome will likely influence not just the future of stock car racing, but the broader legal landscape governing modern professional sports.
