Kalshi Sues Louisiana Over Gambling Laws It Says Target Prediction Markets

Prediction market platform Kalshi has filed a federal lawsuit against the state of Louisiana, asking a court to block enforcement of the state's gambling laws against its operations. The complaint was lodged on October 23, 2026, with the US District Court for the Western District of Louisiana.

The challenge focuses on House Bill 53 and House Bill 883. Both measures were signed into law in May and came into force on August 1, 2026. Kalshi argues that Louisiana has classed sports event contracts as illegal gambling and that the state lacks the statutory power to regulate what it describes as essentially a federal matter.

According to the source, the legislation was written to target unauthorized online casinos, sportsbooks and sweepstakes platforms. Kalshi is concerned, however, that the wording could be applied to its own business. Louisiana has been open about its position that sports event markets should be treated as a form of gambling.

Kalshi says it fears enforcement action is imminent, although the state has not announced any. It is seeking a temporary restraining order, along with preliminary and permanent injunctions. The report notes that this has become a standard approach for the platform in recent months as it faces state-level resistance.

The case is also notable because it will be the first of its kind to fall under the jurisdiction of the US Court of Appeals for the Fifth Circuit.

Kalshi's legal argument rests on the Commodity Exchange Act and on its status as a platform regulated by the Commodity Futures Trading Commission. The company contends that meeting Louisiana's licensing requirements would be incompatible with the federal regulatory framework that governs it. The court has yet to rule on the requests for injunctive relief.
