The National Football League filed an amicus brief with the US Supreme Court on 8 October 2026, supporting New Jersey regulators in their case against Kalshi, the prediction market platform. The NFL argued that sports event contracts offered by Kalshi constitute gambling and must be regulated by individual states rather than treated as commodity contracts under federal jurisdiction overseen by the Commodity Futures Trading Commission. The brief places the NFL in direct opposition to the Trump administration's position on the matter.
The NFL's submission contends that event-based prediction contracts threaten the integrity of professional sport and are susceptible to manipulation. The league's argument centres on whether the CFTC's approval of sports outcome event contracts overrides state-level gambling authority, a question now before the Supreme Court following New Jersey regulators' petition challenging Kalshi's operating model.
Kalshi, as the directly named respondent, is the prediction market platform whose CFTC-approved sports event contracts are the subject of the Supreme Court dispute. CME Group operates regulated derivatives markets and has an established presence in event contract products, placing it within the same regulatory classification debate that this case addresses.
The case represents a significant jurisdictional dispute between federal commodity oversight and state gambling regulation authority. New Jersey authorities initiated the Supreme Court petition contesting the CFTC's approval framework, with the NFL's amicus brief adding a major professional sports voice to the state-regulatory position.
