On October 7, 2025, Kalshi, a platform specializing in prediction market trading, filed a lawsuit against the Ohio Casino Control Commission (OCCC) and Ohio attorney general (AG), alleging that their regulatory actions overstep state authority. The complaint seeks to block enforcement of a cease-and-desist order that was issued by the OCCC in the spring, which accused Kalshi of “operating online sports gaming” and warned Ohio licensees that partnering with Kalshi could jeopardize their licensing status and integrity.
