Kalshi Loses Appeal in 6th Circuit Court, Increasing Likelihood of Supreme Court Review

This ruling intensifies the ongoing conflict between federal and state regulatory frameworks, impacting how prediction markets are governed.

• On September 26, 2026, the 6th US Circuit Court of Appeals ruled against Kalshi, affirming state authority over sports-event contracts.
• The court found that Kalshi's contracts do not qualify as swaps under CFTC jurisdiction, rejecting federal preemption claims.
• This decision adds to a circuit split, raising the likelihood of a Supreme Court review to clarify regulatory authority.

• Kalshi operates as a prediction market under the Commodity Futures Trading Commission (CFTC), claiming its contracts should be treated as swaps.
• Conflicting rulings from the 3rd and 9th Circuits have created uncertainty, with some states asserting their right to regulate these markets as gambling.
• The 6th Circuit's decision aligns with Ohio and Tennessee's stance, emphasizing state control over sports-related contracts.

The 6th Circuit's ruling against Kalshi marks a significant moment in the evolving landscape of prediction markets and regulatory authority. The court unanimously determined that Kalshi's sports-event contracts do not meet the criteria for swaps as defined by the CFTC, thereby allowing state laws to govern these contracts without federal preemption. This decision is pivotal as it underscores the tension between federal oversight and state regulatory power, particularly in the realm of gambling and financial markets.

Kalshi's argument hinged on the premise that its contracts should be classified as swaps under the Commodity Exchange Act, which would preempt state gambling laws. However, the court found that the nature of Kalshi's contracts did not align with the legal definitions necessary for CFTC jurisdiction. This ruling not only affects Kalshi but also sets a precedent for other prediction markets navigating similar regulatory challenges.

The implications of this ruling extend beyond Kalshi itself. With the 6th Circuit's decision, states like Ohio and Tennessee gain clarity and authority to regulate sports-event contracts, potentially leading to a patchwork of regulations across the country. This fragmentation could hinder the growth of prediction markets, as operators may face varying compliance requirements depending on the state.

Moreover, the ruling has prompted Kalshi to express its intent to pursue further appeals, indicating that the company views the current regulatory landscape as unworkable. The involvement of state lawmakers filing amicus briefs and New Jersey's petition for certiorari in its related case suggests that this issue is far from settled. The potential for Supreme Court intervention looms large, as the highest court may need to address the conflicting interpretations of the Commodity Exchange Act and the authority of state regulators.

As the legal landscape evolves, market participants are left in a state of heightened uncertainty. The outcome of this case could significantly influence the future of prediction markets, shaping how they operate and are regulated across the United States.

• Prediction market operators: Facing increased regulatory scrutiny and potential operational hurdles.
• State gaming authorities: Gaining clarity and authority to enforce state regulations on sports-event contracts.
• Investors and participants: Experiencing uncertainty regarding the legality and future of their investments in prediction markets.

• State regulatory responses: Monitor how various states adjust their regulations in light of this ruling and the potential for new legislation.
• Market reactions: Observe how prediction market operators like Kalshi adapt their business models in response to the evolving legal landscape.
