The U.S. Commodity Futures Trading Commission and Department of Justice filed a motion to block Arizona from enforcing gambling laws against prediction market operator Kalshi. Federal regulators argue sports betting contracts are financial derivatives called swaps, falling under federal oversight rather than state gambling regulations. The case centers on whether prediction markets should be regulated as finance or gambling. Arizona has filed criminal charges against Kalshi with arraignment scheduled for April 13. A federal appeals court in New Jersey previously sided with Kalshi, but other courts have supported state enforcement actions. The outcome could determine whether prediction markets operate under a single federal framework or fragmented state-by-state systems.
