On November 12, 2026, Louisiana Attorney General Liz Murrill filed a lawsuit against Kalshi, Polymarket, Robinhood, Coinbase, and Gemini. The state alleges these platforms violate local gambling and sports wagering laws by offering event contracts related to sports, elections, and awards.
The lawsuit seeks a temporary restraining order and an injunction to halt the offering of these contracts in Louisiana. This action follows a 2025 advisory from the Louisiana Gaming Control Board and new 2026 legislation that expanded definitions and penalties for unauthorized gambling.
Kalshi and Polymarket have filed separate federal lawsuits arguing that the federal Commodity Exchange Act preempts state law regarding these derivatives. Kalshi has also requested an emergency court order to block the state's enforcement efforts while the legal dispute continues.
As of November 2026, no final rulings have been issued in the cases. Louisiana is currently one of at least 12 states pursuing enforcement actions against prediction-market platforms, though it is the first to target these five companies in a single joint filing.
