CFTC Sues Kentucky As Prediction Market Fight Spreads To Ninth State

The CFTC has sued Kentucky to block the state from using gaming laws and new transaction fees against federally regulated prediction markets.

The June 23 lawsuit seeks declaratory and injunctive relief against Kentucky, arguing that state enforcement actions against CFTC-regulated designated contract markets interfere with the federal regulator’s exclusive jurisdiction over event contracts. The agency said Kentucky is trying to shut down federally regulated exchanges through state law, monetary penalties and a special transaction fee aimed at prediction market operators.

The case follows Kentucky’s lawsuits against Kalshi and Polymarket, where the state alleged that sports-related event contracts amounted to illegal gambling activity rather than federally regulated derivatives. Kentucky accused the platforms of operating without a state gaming license and offering markets tied to game winners, spreads, player statistics and other sports outcomes.

The CFTC is now pushing the dispute into federal court. Its position is that event contracts traded on registered derivatives exchanges fall under the Commodity Exchange Act, not a patchwork of state gambling rules.

Ninth State Fight Raises Preemption Stakes

Kentucky becomes the ninth state front in the CFTC’s prediction-market campaign. A prior CFTC release listed Arizona, Connecticut, Illinois, New York, Minnesota, Rhode Island and Wisconsin among state actions or disputes, with New Mexico added earlier this month. Kentucky’s case extends the same federal-preemption fight into another major sports-betting state.

CFTC Chairman Michael Selig said Kentucky is attempting to shut down federally regulated event contracts and reiterated that the agency will defend its jurisdiction over prediction markets. The complaint also challenges Kentucky’s special transaction fee on CFTC-regulated designated contract markets, which the agency says was designed to pressure platforms into leaving the state.

The legal clash is now broader than Kalshi or Polymarket alone. States are treating sports event contracts as gambling products that should answer to gaming regulators, licensing rules and responsible-gambling laws. The CFTC is treating them as federally regulated derivatives contracts that cannot be blocked by individual states once listed on registered exchanges.

That split has become one of the biggest policy questions in prediction markets. If states win, sports-related event contracts could face state-by-state licensing, bans, taxes and enforcement actions. If the CFTC wins, registered platforms would gain a stronger nationwide route for offering event contracts under federal derivatives law.

Kalshi And Polymarket Stay In The Middle

Kalshi sits at the center of the federal side because it is a CFTC-registered exchange. Polymarket’s position is more complicated because it is crypto-native, but state lawsuits have increasingly grouped major prediction platforms together when challenging sports-related markets.

The same regulatory fight is expanding while prediction markets enter mainstream finance. Cboe recently launched Cboe Predicts with Mini-S&P 500 binary options, and Meta is reportedly building Arena as a standalone prediction markets app. Those launches show how event-style trading is moving from niche crypto markets into brokerages, exchanges and consumer platforms.

Kentucky’s lawsuits against Kalshi and Polymarket keep the sports-contract issue at the front of the debate. The state wants those products treated like wagering. The CFTC wants a federal court to stop Kentucky from applying gambling law to registered event-contract markets.
