Louisiana AG Wins Temporary Restraining Order Against Prediction Markets
Jesse M. Cox Published 13/11/2026
Louisiana Attorney General Liz Murrill made an impressive showing in court on Thursday. She filed suit against prediction market sites operating in the state and won a temporary restraining order the same day. Louisiana became the first state to sue every prediction market site operating in the state in one action. They are also the first state to secure a temporary restraining order on the filing date.
According to the TRO, all prediction market sites operating in Louisiana may not facilitate event contracts on behalf of any person located in the state of Louisiana. Murrill's lawsuit claims these sites are violating the state's gambling laws.
Louisiana AG works fast to shut down event contracts
Louisiana AG Murrill began her day Thursday by announcing the sweeping lawsuit against prediction market sites operating in the state.
"This morning I filed suit in Louisiana state court against Kalshi, Polymarket, and numerous other illegal online gambling operations," Murrill announced on social media. "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."
Other prediction market sites named in the suit, along with Kalshi and Polymarket, include Robinhood, Crypto.com, Underdog, Coinbase, Gemini, ForecastEx, Novig, and ProphetX.
Louisiana is the 13th state to file a lawsuit against prediction market sites.
And just like that, she got her order
Within hours of filing, Murrill had received the temporary restraining order she was seeking. The order, signed by Tangipahoa Parish Judge Jeffrey Johnson, was posted by Murrill to the social media platform X. According to the TRO, the prediction market companies may not facilitate event contracts on behalf of any person located in the state of Louisiana.
Noting that, in their opinion, these sites are violating Louisiana gambling laws, Murrill argues that event contracts are no different than the sports wagers that legally need to be regulated by the state.
“It’s not complicated," Murrill told NOLA.com. "If you aren’t a licensed gaming operator, you aren’t legal. Illegal gambling is a crime and is subject to jail time and significant penalties.
"Judges all over the country have overwhelmingly called this activity what it is: gambling. Kalshi’s and the other operators’ attempts to make up new words to evade state gambling laws, regulators, and taxes are not fooling anyone."
Prominent gambling attorney Daniel Wallach pointed out that the TRO extends beyond the usual legal tactic of halting sports-event contracts.
"The order reaches sports, elections, awards, and other covered event contracts—not merely traditional sportsbook-style wagers," Wallach wrote on his social media account. "It applies across the defendants' trading, clearing, brokerage, and market-access operations.
The TRO remains in effect for 10 days unless the judge grants an extension.
Louisiana is countering a Kalshi lawsuit
A preliminary injunction hearing will be taking place on November 30 at 9 a.m. Louisiana is the fourth state to gain injunctive relief against prediction market sites, following Michigan, Washington, and Nevada.
Murrill's filing was in response to a lawsuit recently filed by Kalshi in Louisiana. It makes the claim that state gambling laws cannot overrule the federal regulatory powers of the Commodity Futures Trading Commission (CFTC). That's the governing body for all prediction markets.
“The operation of federally-regulated exchanges is the exclusive province of the federal government. Full stop,” Jovy Dedaj, Kalshi’s head of litigation, wrote in an X post on Thursday.
