Louisiana Attorney General Liz Murrill filed a lawsuit Thursday against Kalshi, Polymarket, and eight other prediction market operators, accusing them of operating “illegal online gambling operations.”
- Louisiana's lawsuit names 10 prediction market operators, including Kalshi, Polymarket, Robinhood, and Coinbase.
- Attorney General Liz Murrill is seeking an order to block contracts involving sports, politics, elections, and awards.
- The lawsuit marks the first time a state has targeted so many prediction market operators in a single civil action.
Attorney General Liz Murrill's latest move in the prediction market debate is a lawsuit filed in the 21st Judicial District Court in Tangipahoa Parish. The litigation also targets Robinhood, crypto.com, Coinbase, Novig, Underdog, Gemini Titan, ForecastEx, and ProphetX.
Murrill is seeking an “immediate” restraining order and an injunction to “restore the rule of law” in Louisiana.
“For too long, (prediction platforms) have violated our laws with impunity,” Murrill wrote in a post on X. “No longer.”
🚨BREAKING: This morning I filed suit in Louisiana state court against Kalshi, Polymarket, and numerous other illegal online gambling operations. For too long, they have violated our laws with impunity. No longer: I am seeking an immediate restraining order and an injunction to restore the rule of law in Louisiana.

The lawsuit aims to shut down event contracts in prediction markets in the sports, political, election, and awards categories.
Louisiana is the 13th state to take civil enforcement action against prediction market companies, according to sports betting and gaming attorney Daniel Wallach, who adds it is the first time a single lawsuit has targeted all the companies accused of violating a state's gaming laws.
Setting a new standard?
If the court grants the temporary restraining order, the named operators could be required to stop offering contracts in the markets outlined in the lawsuit.
Beyond that, the companies could face substantial penalties. Louisiana is seeking restitution, disgorgement, and civil penalties against the 10 operators.
Kalshi has already responded to the lawsuit by filing for an emergency temporary restraining order and preliminary injunction against Louisiana in federal court. It noted the threat of imminent enforcement and “criminal, administrative, and forfeiture exposure” in light of discussions with state officials. Prediction market operators named in state suits have often responded by seeking emergency relief.
Louisiana has also taken action against other forms of online gaming. It banned sweepstakes casinos Aug. 1, making it one of a relatively small number of states to prohibit the industry.

Legal battles on multiple fronts
Prediction market operators have obtained restraining orders and injunctions in several state disputes, although recent court decisions have also allowed states to pursue enforcement or denied operators' requests to block it.
States have also taken different approaches to enforcing their gambling laws against prediction markets. Arizona and Utah have filed criminal cases involving prediction market company officials.
The outcome could influence how other states approach enforcement against prediction market operators.
The Commodity Futures Trading Commission (CFTC), the federal derivatives regulator, is also facing scrutiny over its involvement in prediction market litigation. U.S. District Judge Colleen McMahon recently criticized the agency's actions as having “smacked of collusive effort.”
