CFTC Sues Louisiana to Break Injunction Against Kalshi, Polymarket

The Commodity Futures Trading Commission sued Louisiana on Friday, moving to overturn a state-court injunction that temporarily blocks more than 30 prediction-market operators — including Kalshi, Polymarket and Robinhood — from doing business in the state.

The suit marks the sharpest escalation yet in a federal-state fight over who regulates event contracts. Louisiana is now the 12th state the CFTC has sued in its effort to preserve federal authority over derivatives and prediction markets. The agency has also filed friend-of-the-court briefs in four federal appeals courts and one state supreme court in related disputes.

How did the injunction happen?

The sequence was unusually fast. Louisiana Attorney General Liz Murrill filed suit on Thursday, Nov. 12, alleging the companies offered gambling without state licenses. A judge issued a temporary injunction the same day.

The CFTC's complaint zeroes in on process, not just substance. The agency said the order came without advance notice to the defendants or any chance for them to respond before it took effect. That procedural gap sits at the center of the federal case.

What does this change for the operators?

For the platforms named in the state suit, the immediate consequence is a forced market exit in Louisiana — at least until the courts sort out jurisdiction. Three of the affected companies have already pushed back publicly.

• Coinbase said it had no opportunity to respond before the state acted.
• Polymarket argued that prediction markets fall under a federal framework overseen by the CFTC, not state gambling law.
• Robinhood said it is registered with the commission, positioning its event contracts squarely inside the federal perimeter.

Each argument traces the same fault line. If event contracts are federally regulated derivatives, state gambling statutes cannot reach them; if they are wagers, states hold licensing authority. Louisiana's action asserts the second view, and the CFTC's lawsuit asserts the first.

What does this change for the broader market? Potentially a lot. A ruling that upholds Louisiana's approach would give every other state a template for barring prediction-market operators by invoking local gaming law, fragmenting a market the CFTC insists is national by design. A ruling for the platforms would consolidate oversight in Washington and blunt copycat suits elsewhere.

A widening legal front

The numbers tell the story of a regulator playing offense. Twelve states sued. Four federal appeals courts where the agency has filed amicus briefs. One state supreme court. And now a direct action against a state attorney general's own case — an unusual step that signals the CFTC views the Louisiana injunction as an existential threat to its turf rather than a routine enforcement dispute.

The prediction-market sector has grown quickly, with retail platforms rolling out event contracts on elections, sports and macroeconomic outcomes. That growth is exactly what triggered the state-level pushback: regulators like Murrill see unlicensed wagering at retail scale, while the CFTC sees registered or registrable derivatives activity.

The stakes cut both ways for the operators. Losing in Louisiana means more than losing one state's customers — it means a precedent. Winning means a clearer federal framework, but one that will still need the CFTC to actively defend it, lawsuit by lawsuit.

What comes next

The state court has scheduled its next hearing on the injunction for Nov. 30. That hearing will determine whether the temporary block stands, narrows or falls away while the broader federal-state fight proceeds. The CFTC's own suit against Louisiana will run on a parallel track, and the four appellate amicus filings could produce rulings that shape the outcome before the state case fully resolves. For operators and state regulators alike, the next few weeks of filings will map how much of the prediction-market business remains national — and how much gets carved up state by state.
