CFTC Sues Illinois, Arizona, and Connecticut Over Prediction Market Jurisdiction

Apr 3, 2026

The Justice Department and CFTC filed lawsuits on April 2, 2026, against Illinois, Arizona, and Connecticut, asserting exclusive federal jurisdiction over prediction markets under the Commodity Exchange Act. The suits challenge state cease-and-desist orders sent to platforms like Polymarket, Kalshi, and Crypto.com, with Arizona having filed criminal charges against Kalshi for allegedly operating illegal gambling. The Trump administration argues the CFTC has sole authority to regulate sports-related wagers on prediction markets, while states contend these platforms constitute unregulated sports betting. The conflict involves political connections, as Donald Trump Jr. advises both Polymarket and Kalshi, and the federal attorney representing the government previously defended Kalshi against the CFTC in 2024.
