Contested. Connecticut’s Department of Consumer Protection (DCP) treats sports event contracts as unlicensed sports wagering and ordered Kalshi, Robinhood and Crypto.com to stop offering them on December 3, 2025. A federal judge in Connecticut denied Kalshi a preliminary injunction on August 10, 2026, and the Second Circuit denied Kalshi and Coinbase an injunction pending appeal on November 3, 2026.

Is Kalshi legal in Connecticut?
Kalshi is a CFTC-regulated exchange, but Connecticut says its sports event contracts are unlicensed sports wagering. DCP ordered Kalshi to stop on December 3, 2025, and ordered nine prediction market companies, Polymarket among them, to stop offering sports bets in September 2026. Judge Vernon D. Oliver of the federal court in Connecticut denied Kalshi a preliminary injunction on August 10, 2026, and the Second Circuit refused an injunction pending appeal on November 3, 2026, so Kalshi’s appeal goes on without one. The CFTC sued Connecticut over its enforcement on March 31, 2026. For the full regulatory background, see our guide to whether Kalshi is legit and legal.
Is Polymarket legal in Connecticut?
Polymarket operates in Connecticut via its QCX CFTC licence against the same contested backdrop. See how the two compare in our Kalshi vs Polymarket guide.
