Ohio Governor Mike DeWine said the state will pursue further enforcement against prediction market operators offering sports-related contracts, arguing they breach state gambling law.

Governor Mike DeWine has announced that Ohio intends to step up enforcement against prediction market operators that sell sports-related contracts, on the grounds that such products break state gambling law. Cease-and-desist notices have already gone out from the Ohio Casino Control Commission to firms such as Kalshi, Polymarket and Robinhood.
The Ohio Casino Control Commission has proposed a rule restricting sportsbook direct marketing to bettors for 48 hours after they activate or modify a responsible gambling tool.
Kalshi asked the full Sixth Circuit to reconsider its 25 September ruling allowing Ohio and Tennessee to pursue enforcement under state gambling laws. The company argues that federal commodities law gives the CFTC authority over contracts traded on designated exchanges; the court has not accepted that argument.
Ohio casinos recorded August revenue of $93.9m, a year-on-year increase of 5.5%, citing Ohio Casino Control Commission figures. Slots contributed $70m, rising 6%, while table games brought in $23.9m, up 3.9%.
The US Court of Appeals for the Sixth Circuit ruled that Kalshi’s sports-related event contracts did not meet the statutory definition of swaps under the Commodity Exchange Act. The court also found that the Act did not pre-empt Ohio or Tennessee gambling laws, allowing those states’ regulators to pursue enforcement against Kalshi and other prediction-market operators.
