Louisiana Attorney General Liz Murrill sues prediction market platforms including Kalshi and Polymarket
Louisiana Attorney General Liz Murrill posted on X on November 12 that she has filed a lawsuit in state court against Kalshi, Polymarket and several other illegal online gambling operators, seeking an immediate temporary restraining order and injunction. The post said these platforms have violated this state’s laws for years with impunity.
According to local media reports, the defendants also include platforms such as Robinhood, Coinbase, Gemini and Crypto.com. The state says the sports and election event contracts offered by these platforms violate Louisiana gambling and sports betting laws. Previously, Kalshi filed a federal lawsuit against state officials on October 23, and Polymarket did so on October 27, arguing that the Commodity Exchange Act gives the CFTC exclusive jurisdiction over event contracts and that state law may not be enforced.

ABAB AI Insight
This state lawsuit creates a standoff with the platforms’ earlier federal preemption lawsuits. Both Kalshi and Polymarket argue that the CFTC has exclusive jurisdiction over event contracts on designated contract markets, and that state gambling laws are preempted by federal law.
The state characterizes event contracts as unlicensed gambling activity, especially sports-related contracts. The lawsuit also covers both pure prediction market platforms and brokerage and crypto trading platforms that have embedded related functions.
At present, both sides are in litigation, and there has been no final ruling. Similar state enforcement actions have appeared in multiple states, and the core dispute remains the division of jurisdiction between federal regulation and state gambling laws.
ABAB News · Cognitive Law
The lawsuits between prediction market platforms and state governments center on whether event contracts are subject to the Commodity Exchange Act’s exclusive jurisdiction, rather than on a simple classification of the products.
State enforcement can target both specialized prediction markets and traditional brokerage and crypto platforms that have embedded related functions.
