Kalshi sues Louisiana over sports event contract laws

Kalshi has filed a federal lawsuit in Louisiana to stop the state from enforcing its gambling laws against the company’s sports event contracts. For high-risk operators, the point is simple: another prediction-market fight is now heading through federal court, with the usual question sitting underneath it — who gets to regulate these products, the state or the CFTC?

1. Kalshi filed the complaint on 23 October in the US District Court for the Western District of Louisiana. The company is asking for a temporary restraining order, plus preliminary and permanent injunctions, to block any enforcement action against it before Louisiana acts.
2. The lawsuit targets House Bills 53 and 883, which were signed in May and took effect on 1 August 2026. Kalshi says Louisiana has labeled sports event contracts as illegal gambling, but does not have the authority to regulate products it views as subject to federal oversight.
3. The case adds another front to Kalshi’s wider legal fight over prediction markets and state gambling law, and it lands in the jurisdiction of the US Court of Appeals for the Fifth Circuit. That matters because the same basic issue keeps recurring: whether states can pull sports-related prediction contracts into their own gambling frameworks.
4. The filing comes after earlier disputes in other states. In August, the CFTC ordered Kalshi to continue trading despite New York Attorney General Letitia James’ lawsuit, relying on its emergency authority under the Commodity Exchange Act (CEA), which the agency says gives it federal authority over contract markets.
5. Also in the background: on July 7, a federal judge in New York denied Kalshi’s request for a preliminary injunction against the state gaming regulator, and on July 27 rejected its request for protection pending appeal. In June, Kalshi filed a separate complaint against Minnesota’s SF 3432, which was signed into law by Governor Tim Walz and bans prediction markets from August 1, 2026, with criminal penalties attached.

For PSPs, acquiring teams, and banks that touch sports event contracts, the useful detail is not the headline fight itself but the regulatory split behind it: Kalshi is testing the argument that federal oversight under the CEA should preempt state gambling enforcement, while states are writing laws that treat the same activity as gambling and, in Minnesota’s case, as a criminal matter.
