Kentucky Targets Kalshi And Polymarket In Illegal Sportsbook Lawsuits

Kentucky Attorney General Russell Coleman has launched civil enforcement lawsuits against Kalshi, Polymarket and VGW, accusing the companies of operating illegal betting or gambling platforms in the state without proper licensing.

The Kalshi and Polymarket suits focus on sports event contracts. Kentucky alleges the platforms allow users to place wagers on game winners, point spreads, player statistics and other sports outcomes while doing business in the state without a Kentucky gaming license or the consumer protections required under state law.

The lawsuits were filed in Franklin Circuit Court on June 17. Kentucky’s claims include alleged violations of consumer-protection laws, the state’s loss recovery act and newer rules aimed at prediction-market activity. VGW, which operates social casino brands including Chumba Casino, Global Poker and LuckyLand Slots, was sued in a separate gambling case.

Sports Contracts Sit At The Center Of The Fight

The legal fight is another test of whether sports event contracts should be treated as federally regulated derivatives or state-regulated sports betting. Kalshi has long argued that its event contracts fall under Commodity Futures Trading Commission oversight, while states including Kentucky are trying to apply local gambling, sports-wagering and consumer-protection rules.

Kentucky’s complaint puts the sports side of prediction markets under direct pressure. The state is not only objecting to political, economic or entertainment markets. Its case targets contracts tied to sports outcomes, where the overlap with regulated sportsbooks is easiest for state officials to argue.

The timing adds tension because Kentucky is already fighting the industry over money. A coalition including Kalshi, Crypto.com and Polymarket recently challenged Kentucky’s 14.25% excise tax on prediction-market fees, arguing the levy is discriminatory and preempted by federal law. Kentucky is now fighting on two fronts: taxing prediction-market operators that serve state users, and suing platforms it says are offering unlicensed sports betting.

State Crackdown Keeps Spreading

Kentucky is not acting alone. State pressure on prediction markets has widened across the U.S. and Europe as regulators question whether platforms are using derivatives law to route around gaming licenses, tax rules and responsible-gambling controls.

Wisconsin already moved against Kalshi and Polymarket in a sweeping prediction-market crackdown, while gaming industry groups pushed lawmakers to ban sports prediction markets in the CLARITY Act. The pressure has also moved into Congress, where a House Oversight probe into Kalshi and Polymarket raised questions about safeguards for users with access to non-public government information.

Those cases are not identical, but they point to the same regulatory split. Prediction-market operators want a national framework built around event contracts. States and gaming groups want to preserve control over sports betting, gambling licenses, age limits, problem-gambling rules and tax revenue.

Kentucky Raises The Stakes For U.S. Prediction Markets

Kentucky’s lawsuits arrive as prediction markets try to move from niche forecasting platforms into mainstream trading apps. Sports contracts have helped fuel that growth because they are simple, frequent and easy for users to understand. They also make the platforms look more like sportsbooks to state regulators.

Kalshi’s federal-regulation argument may still shape the case, especially where CFTC jurisdiction overlaps with state gaming law. Polymarket faces a different but related challenge because its crypto-native structure and U.S. expansion plans keep drawing scrutiny from both gambling regulators and market regulators.
