The pile of lawsuits against Kalshi just grew by one

Arkansas filed suit against Kalshi, alleging the prediction market operates illegal gambling, adding to actions brought by Utah and other U.S. states. The suit escalates a multistate challenge to Kalshi's regulatory model as a CFTC-supervised exchange rather than a state-licensed gambling operator. Kalshi has argued its event contracts are federally regulated derivatives, a position that has so far held in federal court. The case matters because a state win could force Kalshi to seek gambling licenses or restrict offerings in those jurisdictions, fragmenting its national market. Watch for rulings on federal preemption and whether more states follow Arkansas, Utah and others in filing.
