Prediction market operator Polymarket is facing its first major legal challenge in Nevada, as the state’s gaming regulator has sued to block the company from offering sports event contracts in the state.

The Nevada Gaming Control Board filed for a court order this week in Carson City district court, seeking an injunction to stop what it calls “unlicensed wagering” and asserting that sports-linked contracts fall under the state’s gambling laws.

It’s the latest filing in a long list of battles between state gambling regulatory bodies and prediction market platforms unfolding in US court systems.

Nevada is embroiled in a case against Polymarket rival Kalshi, in which a federal judge ruled in November that the state could enforce its cease-and-desist order on the platform.
