Nevada vs. Prediction Markets: Ninth Circuit Weighs Federal Swap Preemption Amid State Gambling Enforcement
Overview
In April 2026, the Ninth Circuit heard a pivotal case where Nevada challenged prediction market platforms like Kalshi over whether their sports-event contracts are illegal gambling or federally regulated financial swaps. The platforms, supported by the CFTC, argue these contracts fall under federal law, while Nevada insists they are wagers subject to state regulation, crucial for its gaming revenue. The Ninth Circuit panel showed skepticism about the platforms' claims, especially given CFTC rules banning gaming contracts. This dispute deepens a circuit split, with the Third Circuit favoring federal preemption and other courts backing states. The unresolved conflict threatens Nevada's finances, fragments regulation, and likely invites Supreme Court review to clarify federal and state authority.
