Polymarket US Seeks Court Order Against Ohio Sports Contract Halt

Polymarket US is asking a court to block Ohio from stopping its sports event contracts, putting the reach of state gambling rules over federally regulated prediction markets at issue.

The company seeks preliminary and permanent injunctions against Ohio's demand. The preliminary request would provide relief while the case proceeds; the permanent request would prevent the state from enforcing its demand on an ongoing basis. Together, the two requests target both the immediate halt and its long-term effect.

Ohio demanded an immediate halt to the sports contracts and required written confirmation of compliance by Oct. 16.

At issue is whether Ohio can apply its gambling rules to sports event contracts offered through a prediction market under federal oversight. The dispute places a state enforcement order alongside the federal framework governing prediction markets, testing where each authority applies.

Polymarket US's court requests seek relief from Ohio's demand, with one applying during litigation and the other intended to remain in force after a final decision.
