Whether a sports wager counts as a financial “swap” could determine whether states can regulate the exchange selling it. In a new legal analysis, Sportico’s Michael McCann explains the dispute behind the NFL’s Supreme Court intervention: federal oversight of derivatives is being invoked to put sports-event contracts beyond the reach of state gambling rules.

The Third Circuit sided with Kalshi in Kalshi v. Flaherty, reasoning that the Commodity Exchange Act gives the Commodity Futures Trading Commission exclusive jurisdiction over the relevant contracts. McCann describes conflicting appellate decisions and briefs asking the Supreme Court to review that approach. The NFL, former Senator Christopher Dodd, former CFTC chair Gary Gensler, and tribal and casino organizations are among those urging review. Their briefs are arguments, not a ruling that the Court will take the case.

Dodd and Gensler challenge the premise that the Dodd-Frank financial reforms turned sports bets into swaps. Dodd argues that an event must have a potential financial, economic or commercial consequence independent of the wager’s own payout. Otherwise, he warns, “every bet would become a swap because money changes hands.” Gensler likewise argues that Congress did not transfer sports-betting jurisdiction from states to the CFTC. Both positions concern the intended scope of a financial statute, rather than whether an exchange uses different pricing mechanics from a sportsbook.

The CFTC takes the other side. McCann reports that its new interim final rule distinguishes traditional sportsbook and casino products, which it says are not swaps, from prediction-market contracts it claims authority to regulate. That distinction is the mechanism at issue: substantially similar exposure to a sporting outcome can come with a different regulator depending on how the transaction is structured.

For the NFL, the practical concern is contracts on events vulnerable to manipulation or involving injuries, misconduct and fan safety. Its brief says the league warned operators against contracts such as whether a kicker misses a field goal or how often a topic is mentioned on a broadcast. These are the league’s stated risk concerns, not evidence that a particular game has been manipulated. Players, officials and market participants would bear the consequences if those risks materialized.

The broader stakes are the enforceability of state licensing requirements and decisions about where sports gambling may operate. Exclusive federal jurisdiction could let exchanges offer contracts where conventional sportsbooks cannot; tribal lands raise additional questions under the Indian Gaming Regulatory Act. McCann thinks the conflicting court decisions strengthen the case for Supreme Court review, but that remains his assessment. Kalshi’s response is due November 9, and the Court has not yet resolved the dispute.
