US Supreme Court Urged to Clarify Prediction Market Regulation Amid CFTC Push

Washington D.C. – The U.S. Supreme Court faces growing pressure to resolve a contentious debate over the regulatory classification of prediction markets. Last week, a diverse array of stakeholders, including 39 states, 145 tribal nations, and prominent former federal officials, filed amicus briefs urging the high court to hear a case that could redefine the oversight of these popular platforms.

At the heart of the dispute is whether contracts offered by sports-based prediction markets constitute "swaps"—financial instruments regulated by the Commodity Futures Trading Commission (CFTC)—or are fundamentally gambling products subject to state-level control. The outcome could significantly impact the burgeoning prediction market industry and the broader digital asset landscape.

Jurisdictional Battle Lines Drawn

Many of the amicus briefs filed last week advocate for state jurisdiction, asserting that sports-related prediction markets are akin to gambling and should not be regulated by the CFTC. This stance directly challenges a prior 2-1 ruling by the Third Circuit Court of Appeals, which had affirmed the CFTC's authority over such markets.

Former Senator Chris Dodd, co-author of the landmark 2010 Dodd–Frank Wall Street Reform and Consumer Protection Act, submitted a brief arguing that the legislation was never intended to empower the CFTC to override state gambling laws. Dodd’s filing emphasized a clear distinction between financial derivatives and sports wagers, citing complex sports parlays as examples that do not facilitate hedging or price discovery, thereby failing to meet the criteria for swaps under the Commodity Exchange Act (CEA).

Similarly, former CFTC and Securities and Exchange Commission Chair Gary Gensler, who was instrumental in implementing Dodd-Frank regulations, echoed Dodd’s position. Gensler contended that the law did not grant the CFTC the authority to preempt existing state gambling statutes. The National Football League (NFL) also weighed in, highlighting its vested interest in the issue given the prominence of sports betting. The league criticized what it termed the CFTC's “laissez-faire” approach and the regulatory divergence between how states oversee gambling companies and how the CFTC regulates designated contract markets.

CFTC Moves to Clarify Definitions

Amidst the mounting legal challenges, the CFTC on Friday released an interim final rule, which is now in effect, alongside a separate proposal. These measures aim to clarify the agency's interpretation of how prediction market products fit within the definition of a "swap." The regulator explicitly stated that casino-style gambling falls outside its definition of a swap. However, it maintained that event contracts remain within this definition.

Crucially, the CFTC’s proposal seeks to formally include contracts tied to sports, political outcomes, cultural events, and weather phenomena as “event contracts” that would be counted as swaps. This move underscores the agency’s intent to solidify its claim to exclusive jurisdiction over these types of markets, setting the stage for a potential showdown should the Supreme Court decide to hear the case. Kalshi, a prominent prediction market platform, has been granted an extension until November 9, 2026, to submit its response to the Supreme Court.

Why it matters

The Supreme Court’s decision to take up this case, or the lack thereof, will have profound implications for the regulatory landscape of prediction markets, particularly those leveraging blockchain technology. A ruling affirming state control could fragment regulation across jurisdictions, potentially hindering the growth of national platforms. Conversely, a decision upholding the CFTC’s authority would provide a clearer, albeit federal, regulatory path, impacting how these products are structured, offered, and accessed by consumers. This clarity is crucial for innovators and investors in the burgeoning digital assets and event contract space.

What to watch

All eyes will now be on the Supreme Court to see if it grants certiorari—agreement to hear the case. Should the court decide to intervene, the legal arguments from both sides, particularly concerning the interpretation of Dodd-Frank and the CEA, will be closely scrutinized. The deadline for Kalshi’s response in early November will be a key milestone. Meanwhile, the CFTC’s ongoing rulemaking process will continue to shape the federal stance, even as the broader jurisdictional question remains unresolved.
