Key Takeaways

  • Louisiana filed a civil lawsuit on 12 November 2026 against 10 prediction market operators, including Kalshi and Polymarket.
  • The complaint was filed in the 21st Judicial District Court in Tangipahoa Parish and demands restitution, disgorgement of profits and civil penalties.
  • Kalshi sued state officials on 23 October 2026 and filed an emergency request for a temporary restraining order and preliminary injunction on 12 November 2026 in federal court.
  • Louisiana is the 13th state to pursue civil enforcement against prediction markets and the first to target ten companies in a single lawsuit.

Louisiana filed a civil lawsuit on November 12, 2026, against 10 prediction market operators, including Kalshi and Polymarket, seeking to stop event contracts tied to sports, elections, politics and awards and to obtain restitution, disgorgement of profits and civil penalties. The complaint was lodged in the 21st Judicial District Court in Tangipahoa Parish and names Robinhood, crypto.com, Coinbase, Novig, Underdog, Gemini Titan, ForecastEx and ProphetX alongside Kalshi and Polymarket.

Kalshi has already moved in federal court. The company sued state officials on October 23, 2026, and filed an emergency request for a temporary restraining order and a preliminary injunction on November 12, 2026, arguing that federal commodities law gives the Commodity Futures Trading Commission authority over its event contracts. Louisiana, led by Attorney General Liz Murrill, treats the same contracts as gambling products subject to state regulation. The dispute now involves competing state and federal proceedings, with both sides seeking orders that could determine whether prediction market operators may continue serving Louisiana customers.

Scope of the state complaint and remedies sought

Attorney General Liz Murrill filed the complaint Thursday in Tangipahoa Parish and described the defendants as running “illegal online gambling operations.” The state is seeking an immediate restraining order and an injunction to halt the contracts while litigation continues. Beyond injunctive relief, Louisiana is demanding restitution, disgorgement of profits and civil penalties from the named companies.

Regulatory context and significance

Gaming attorney Daniel Wallach observed that Louisiana is the 13th state to pursue civil enforcement actions against prediction market companies, though it is the first to consolidate ten operators in a single lawsuit. Louisiana previously tightened online gambling rules when legislation banning dual-currency sweepstakes casinos took effect on August 1, 2026, and that law expanded enforcement powers, including the ability to seek court injunctions against prohibited online gambling activity.

“For too long, (prediction platforms) have violated our laws with impunity,” Attorney General Liz Murrill wrote on X on November 12, 2026, adding “No longer.”

The state lawsuit is the first instance of a single civil action listing this group of operators together; no court has yet ruled that the platforms violated Louisiana gambling laws. The competing federal claim rests on CFTC authority over event contracts, while Louisiana argues state gambling statutes apply. Relevant coverage of evolving oversight sits at regulation and the operational mechanics of prediction markets are followed in sports.
