Polymarket US sues Ohio over sports contracts enforcement

The prediction market's CFTC-registered entity argues federal law should override Ohio's push to shut down its sports event contracts Polymarket US has taken Ohio to federal court. The prediction market is fighting state cease-and-desist orders that target its sports event contracts. The company is suing through QCX LLC, its entity registered with the CFTC. The defendants are Ohio state officials, including Interim Attorney General Andy Wilson. The core argument is that federal law, not Ohio’s gambling rulebook, should decide whether these contracts can be offered to Ohioans. The lawsuit was filed between October 16 and 19, 2026.
