Prediction markets in Kentucky

Contested — no ruling yet
Kentucky went after the venues and the distribution layer together. The Attorney General filed two complaints in Franklin Circuit Court in June 2026 — one against Kalshi and the brokerages carrying its contracts, Coinbase, Robinhood and Webull, the other against Polymarket US’s QCX — and both were removed to federal court, where Kentucky’s motion to send the Kalshi case back is awaiting a ruling. The legislature added a 14.25% excise tax on prediction-market activity. The United States and the CFTC then sued the Commonwealth, challenging the tax as well as the enforcement, and a platform trade group, the Coalition for Fair Markets, which had sued over the tax in state court in June, is litigating that challenge in the federal case; the cross-motions were fully briefed on September 21. Kentucky sits in the Sixth Circuit, which ruled against Kalshi’s preemption theory on September 25.

The federal-vs-state fight

Every entry in this fight turns on the same question: does a prediction-market platform's federal regulation by the CFTC preempt a state's gambling law, or does the state retain authority to restrict it? Courts around the country are answering that question differently — sometimes for the platform, sometimes for the state — and almost every ruling so far is preliminary and under appeal. Treat this page as a snapshot, not a final word.

This page is informational, not legal advice. Nearly every litigation entry referenced here is a preliminary ruling under appeal. Always verify a platform's current, location-specific eligibility directly with the venue before relying on this page.
