Louisiana Sues Kalshi and Polymarket Over Event Contracts in State Court

Louisiana has sued Kalshi and Polymarket in state court, seeking an immediate order to block event contracts that the state says violate its gambling and sports betting laws.

Attorney General Liz Murrill announced the case against the prediction-market platforms and other operators she described as illegal online gambling businesses. The state is asking a judge to issue a restraining order and an injunction, seeking to stop the challenged contracts through court action.

Louisiana alleges that offering the event contracts violates its gambling and sports wagering laws. The requested relief centers on stopping the platforms' activity, while the lawsuit puts the legality of the contracts under state law before a state court.

Kalshi and Polymarket had also sued Louisiana officials in federal court, creating parallel court disputes. Louisiana's case is in state court, while the companies' earlier cases are in federal court.
