The Commodity Futures Trading Commission just filed its ninth lawsuit against a US state in roughly two months, and this time the target carries a twist. Kentucky, sued on June 23, is the first state in this growing legal saga with a Republican attorney general on the other side of the table.
The fight is about a deceptively simple question: are prediction markets federally regulated derivatives, or are they state-regulated gambling? The answer will determine the future of an industry with trading volumes now surging into the billions.
What happened
Kentucky Attorney General Russell Coleman filed lawsuits on June 17 against Kalshi and Polymarket, alleging both platforms were engaged in unlicensed sports betting under state law. Six days later, the CFTC sued Kentucky to block those actions.
The federal agency’s argument is straightforward. Event contracts traded on platforms like Kalshi and Polymarket function as swaps or derivatives under the Commodity Exchange Act. That makes them the CFTC’s turf, not Kentucky’s.
