Is Polymarket legal in Ohio?
Yes, but contested: Polymarket's sports contracts face an open dispute in Ohio, with no restriction in force. The Ohio Casino Control Commission ordered Polymarket US (PM US Tech, QC Tech LLC) on October 2, 2026 to stop offering sports event contracts to people in Ohio, calling them unlicensed sports gaming and bookmaking, and gave it 14 days to confirm in writing. It relies on the Sixth Circuit's September 25, 2026 ruling that Ohio's sports gaming law applies. No court order is in force, and Polymarket US's app listing names only Nevada as closed.

How this compares to Ohio sports betting
Where a state allows sports betting, sportsbooks are licensed and taxed by that state; an event contract on a federal exchange is neither, which is the whole dispute. The Ohio action concerns Polymarket's sports contracts. Whether a state may enforce at all is the question the federal appeals courts have split on. Ohio is in the Sixth Circuit. On September 25, 2026, it held that Kalshi's sports contracts are not swaps and fall under state gaming law (No. 26-3196). Litigation tracker
