Are prediction markets legal in Connecticut?
Contested. Connecticut sent cease-and-desist letters to Kalshi and other prediction-market providers, a federal court refused to block the state in August 2026, and Connecticut has sued Kalshi in its own courts. The CFTC is suing Connecticut. No platform we review excludes Connecticut in its terms yet.
Of the 26 platforms we review, 8 are open in Connecticut, 4 with restrictions and 11 not at all; for 3 the terms do not say. Sports betting in Connecticut: legal, regulated by the Department of Consumer Protection (storage.courtlistener.com).
Not legal advice. Eligibility usually follows where you are when you trade, and a platform can refuse an individual account. Checked 29 September 2026.

The international polymarket.com site is closed to US residents: no deposits and no trades. The help centre lists the US as blocked and the API docs list it as close-only. US residents are sent to the separate Polymarket US app, run by QCX LLC (a CFTC DCM). Polymarket US state-level eligibility was not verified because its ToS page loads its text client-side.
Listed in the Terms (updated 24 Jan 2025) among countries whose residents may not use Real-Money Services. Play-money (Ooms) markets stay open, and the app tells users from Restricted Jurisdictions they can still bet play money.
QCX LLC publishes no list of eligible or excluded states. A Nevada court granted a preliminary injunction against QCX LLC d/b/a Polymarket US on 29 May 2026 (Nevada Gaming Control Board). Missouri's Attorney General has sent a cease-and-desist over sports contracts, and New York has announced a lawsuit; neither state is marked closed because the operator has not said it geoblocks them.
ProphetX says it is “available nationwide” but publishes no excluded-state list; its help centre says access “is restricted from certain locations and IP addresses”. Connecticut reportedly ordered it to stop offering sports contracts to residents (September 2026); the order could not be read on the regulator’s site.
