Last updated: June 2026

Prediction markets in Connecticut sit under federal regulation by the Commodity Futures Trading Commission, the CFTC, not the state. As of June 2026, Connecticut is one of the states actively challenging prediction markets, so the picture is contested. Trading often continues while the legal fight plays out, but the situation can change quickly.

Is Kalshi or Polymarket legal in Connecticut?

The current status is Contested. Connecticut’s consumer-protection regulator issued a cease-and-desist in December 2025, and the CFTC has sued the state.

Here is how that breaks down by platform. Kalshi takes the position that it is legal in Connecticut under federal CFTC authority and generally keeps operating while the state’s challenge plays out in court. Polymarket’s US arm operates in Connecticut, available to verified users on its regulated US platform.

Why this matters in Connecticut

Connecticut already licenses its own online casinos, so a state-licensed casino is the safer route for casino games. Prediction markets matter here mainly for the event contracts that casinos and sportsbooks do not offer, like politics and economics. That is the practical reason the legal question gets searched so often: for a lot of people in Connecticut, this is about access to something they cannot easily get another way.

Whatever the local status, the same federal picture applies underneath. The CFTC regulates these markets nationwide, the platforms hold customer money in segregated accounts, and a bloc of states disputes whether sports event contracts belong to the CFTC or to state gambling law.
