Louisiana Attorney General Liz Murrill has filed a state court lawsuit against five prediction market operators: Kalshi, Polymarket, Robinhood, Coinbase and Gemini. The state alleges their event contracts on sports, awards and elections break Louisiana gambling and sports wagering laws.

The suit seeks an immediate temporary restraining order and an injunction that would stop the platforms from offering those contracts in the state. It is the first time Louisiana has targeted a broad group of prediction market platforms in a single filing.

Kalshi sued the state preemptively in federal court on October 23, and Polymarket has also filed a federal case, both arguing the Commodity Exchange Act preempts state law. Kalshi is now seeking an emergency court order against the state.

No final rulings have been issued in any of the Louisiana cases. Similar enforcement actions are active in at least 12 other states, and naming Coinbase and Gemini signals that states are not separating crypto exchanges from dedicated prediction market operators.
