Ninth Circuit Ruling Defines Sports Contracts Outside Federal Swap Oversight

The U.S. Court of Appeals for the Ninth Circuit issued its decision on August 28, 2026, in cases involving KalshiEX and related platforms, determining that contracts tied to sports events do not qualify as swaps under the Commodity Exchange Act. Platforms such as Kalshi, Crypto.com, and Robinhood had sought federal treatment for these offerings, yet the court held that such contracts remain subject to state gambling regulations instead. This outcome dissolves prior injunctions that had blocked Nevada gaming authorities from enforcement actions. The Ninth Circuit reviewed arguments that prediction market contracts function as financial instruments regulated solely by the Commodity Futures Trading Commission. Judges rejected that position after examining the structure of the contracts, which centered on outcomes of athletic contests rather than commodity prices or economic indicators. The ruling emphasizes that state laws governing wagers apply directly when events involve sports competitions.

Background on the Legal Challenge

Kalshi and similar operators launched markets allowing users to trade positions on sports results while framing the activity as swap transactions eligible for federal oversight. Nevada regulators moved to enforce licensing and operational rules applicable to gaming businesses, prompting the platforms to seek court protection. Lower courts initially granted relief based on preemption claims, but the appeals process shifted the analysis toward state authority within the Ninth Circuit's jurisdiction.

Evidence presented during hearings showed that contract payouts depended exclusively on game scores and team performances, aligning more closely with traditional betting mechanics than with standardized swap agreements. The Commodity Exchange Act defines swaps through references to underlying assets such as interest rates or currencies, criteria the sports contracts failed to satisfy according to the court's review.

Details of the August 2026 Decision

The Ninth Circuit opinion affirming dissolution of the injunction against Nevada gaming enforcement (Aug. 28, 2026) examined the Commodity Exchange Act's text alongside state statutes. Judges concluded that federal law does not preempt enforcement when contracts involve sporting events, allowing Nevada and other states in the circuit to apply their regulatory frameworks. This approach contrasts with positions advanced by the platforms, which argued for exclusive Commodity Futures Trading Commission jurisdiction.

Platform representatives contended during oral arguments that treating these contracts as swaps would promote uniform national standards and reduce compliance burdens across multiple jurisdictions. State officials countered that sports-based markets fall squarely within gambling definitions established under Nevada law, requiring appropriate licensing and consumer protections. The court sided with the state position after analyzing the economic substance of the transactions rather than their labeling.

Intercircuit Conflict and Precedent

An earlier Third Circuit ruling had favored federal preemption in a comparable dispute, creating divergent standards depending on geographic location. The Ninth Circuit decision highlights this split by declining to follow the Third Circuit's reasoning on swap classification. Observers tracking regulatory developments note that such conflicts often prompt higher court review to establish consistent nationwide rules.

Cases involving Crypto.com and Robinhood followed similar procedural paths, with the Ninth Circuit consolidating aspects of the appeals for efficiency. Each platform had offered markets on professional and collegiate sports outcomes, prompting parallel challenges from state regulators in California, Nevada, and other covered states. The unified opinion addresses common legal questions across these matters.

Expected Path to Supreme Court Review

Legal analysts tracking the proceedings indicate that petitions for certiorari to the U.S. Supreme Court are likely within the coming months. The existence of conflicting appellate decisions on whether sports event contracts constitute swaps under federal law provides grounds for review under established Supreme Court criteria. Resolution at that level would clarify the boundary between Commodity Futures Trading Commission authority and state gaming oversight.

Platform operators have signaled continued operation of non-sports markets while adjusting sports-related offerings to comply with state requirements pending further appeals. State regulators in the Ninth Circuit now possess clearer authority to initiate enforcement proceedings without federal court interference based on preemption grounds.

Conclusion

The Ninth Circuit's August 2026 ruling establishes that sports event contracts on prediction platforms remain subject to state gambling laws rather than federal swap regulations under the Commodity Exchange Act. This outcome enables Nevada and other states within the circuit to apply their existing frameworks while setting the stage for potential Supreme Court consideration to address the split with the Third Circuit. The decision rests on analysis of contract terms, statutory definitions, and the distinction between athletic outcomes and traditional financial underlyings.
