The Commodity Futures Trading Commission (CFTC) has filed lawsuits against Arizona, Connecticut, and Illinois, reaffirming its exclusive jurisdiction over event contracts and prediction markets under the Commodity Exchange Act. The CFTC accuses the three states of attempting to prohibit, restrict, or regulate registered designated contract markets, including platforms like Kalshi and Polymarket, through other state-level regulatory measures. The CFTC requests the federal court to declare the state actions invalid and to prohibit the states from interfering with prediction market activities that comply with federal regulations.
