Kentucky's allegations
Kentucky accused the platforms of "operating unlicensed and illegal sports betting and gambling platforms" without a Kentucky gaming license or compliance with state regulations. The state alleged the platforms offer users "few or no resources" to identify or seek help for gambling problems, as required by Kentucky law.
Coleman's statement framed the dispute bluntly: "Kalshi and Polymarket are operating illegal sportsbooks in Kentucky and breaking our laws. These multi-billion dollar corporations and their legal fictions don't pass the sniff test."
The broader legal landscape
Kentucky isn't alone. At least 17 other states have taken prediction market operators to court. Montana, Nevada, Utah, Iowa, Illinois, Ohio, Tennessee, New York, New Jersey, Connecticut and Maryland issued cease-and-desist letters, while Washington, Arizona, New Mexico, Wisconsin, Michigan, Massachusetts and Kentucky have chosen to sue.
The core dispute hinges on regulatory authority. Multiple state authorities have argued that event contracts tied to sports are sports betting and require state-level licenses. Prediction markets have argued that their event contracts are swaps regulated under federal commodities law.
Courts have split. A Michigan federal judge ruled against Polymarket in its lawsuit against the state, finding that its sports event contracts are not swaps under the CFTC's authority. But the Third Circuit Court of Appeals ruled in April that New Jersey regulators could not prevent Kalshi from offering sports event contracts in the state.
Prior disputes and market scale
This isn't Kentucky's first clash with prediction markets. Kalshi and Polymarket previously sued Kentucky over its 14.25% tax on prediction market transaction fees.
The stakes are substantial. Kalshi and Polymarket together recorded $25 billion in monthly trading volume in May, per Token Terminal. The CFTC has sued eight states after they took action against prediction markets, claiming they were stepping on its authority.
Kalshi's response emphasizes federal oversight. A spokesperson said: "Kalshi is a federally regulated exchange — the CFTC is our regulator, not the states. Courts have already recognized this, and we're confident they will here too."
