Ninth Circuit Decision Reinforces State Gambling Oversight in Prediction Market Cases
The U.S. Court of Appeals for the Ninth Circuit issued a unanimous 3-0 decision in late August 2026 that determined Kalshi’s sports event contracts do not qualify as swaps under the Commodity Exchange Act, which places them under the jurisdiction of state gambling laws instead. This ruling upheld a lower court’s decision to dissolve an injunction that had previously blocked Nevada regulators from enforcing those laws against the platform, and it directly addresses how platforms structure and label such products.
Details of the Ninth Circuit Ruling
The appeals court examined whether contracts tied to sports outcomes could be reclassified as swaps to fall under federal Commodity Futures Trading Commission oversight, yet the three-judge panel concluded that the nature of the underlying activity remains betting on events and therefore subject to state authority regardless of terminology. Observers note that the decision relies on the substance of the contracts rather than their marketing descriptions, and it affirms Nevada’s ability to regulate these offerings as gambling activities.
Kalshi had argued for federal preemption through the CFTC, but the Ninth Circuit found no basis for that protection in this instance because the contracts involve event outcomes rather than financial instruments that traditionally qualify as swaps. The opinion, filed August 28, 2026, emphasizes that state laws continue to apply when platforms offer contracts that mirror traditional wagers on sports results.
Background Leading to the Dispute
The case originated when Nevada regulators moved to enforce state gambling statutes against Kalshi’s sports-related offerings, prompting the company to seek an injunction in federal district court to prevent enforcement. After the lower court lifted the injunction, Kalshi appealed to the Ninth Circuit, where the panel reviewed whether the Commodity Exchange Act could shield the contracts from state oversight. Data from the proceedings show that the contracts in question allow users to take positions on specific sports events, which the court determined align more closely with gambling than with regulated swap transactions.
Similar platforms face the same classification questions, and the Ninth Circuit’s analysis applies broadly to any entity attempting to frame sports event contracts as swaps to avoid state-level rules. Those who have followed the litigation observe that the ruling clarifies boundaries between federal derivatives regulation and state gambling enforcement without creating new exceptions for prediction markets.
Circuit Split Emerges with Third Circuit Precedent
The Ninth Circuit decision stands in direct contrast to an earlier ruling from the Third Circuit that favored federal preemption through the CFTC for comparable contracts. Legal experts point out that this divergence creates a circuit split, which increases the likelihood that the U.S. Supreme Court will eventually review the issue to resolve the inconsistency across jurisdictions. The split means that platforms operating in different circuits encounter varying standards, with the Ninth Circuit states now aligned toward state authority and the Third Circuit states leaning toward federal oversight.
Because the circuits disagree on whether sports event contracts qualify for swap treatment under the Commodity Exchange Act, parties on both sides of the debate anticipate further appellate action. The Ninth Circuit panel explicitly acknowledged the conflicting Third Circuit precedent yet reached its own conclusion based on the record presented in the Nevada case.
Responses from Kalshi and Nevada Officials
Kalshi issued a statement indicating that it plans to seek further review of the Ninth Circuit decision, including potential en banc consideration or a petition to the Supreme Court. The company maintains that its contracts should receive uniform federal treatment to avoid a patchwork of state regulations. Nevada’s attorney general described the ruling as a straightforward affirmation of state authority over sports betting activities, irrespective of how platforms label the products or structure the transactions.
Both parties have outlined next steps that center on the circuit split, and the disagreement highlights ongoing tensions between federal derivatives oversight and traditional state gambling controls. Figures from court filings reveal that the contracts at issue generated substantial user activity before the injunction proceedings began, underscoring the practical stakes for regulators and operators alike.
Legal Implications and Future Outlook
Those who have studied similar regulatory disputes note that the Ninth Circuit’s emphasis on contract substance over form may influence how other prediction market platforms design their offerings going forward. The decision does not prohibit sports event contracts outright but requires that such products comply with applicable state gambling laws in the Ninth Circuit’s jurisdiction. Researchers tracking these cases find that the ruling provides clearer guidance for state attorneys general seeking to enforce existing statutes against platforms that attempt to operate under federal derivatives authority alone.
The circuit split itself serves as a focal point for future litigation, and the Supreme Court’s potential involvement could establish a nationwide standard for classifying these contracts. Data from prior CFTC actions show that the agency has previously asserted jurisdiction over certain event contracts, yet the Ninth Circuit’s analysis limits that reach when sports outcomes form the core of the product.
Conclusion
The Ninth Circuit’s unanimous ruling solidifies state regulatory power over Kalshi’s sports event contracts in the affected jurisdictions while highlighting the divide with the Third Circuit’s approach. As Kalshi pursues additional review and Nevada officials proceed with enforcement based on the decision, the case continues to shape the boundary between federal and state oversight of prediction markets. The outcome of any further appeals will determine whether a uniform national framework emerges or whether platforms must navigate differing rules by circuit.
