Connecticut’s position
Connecticut legalised sports betting in 2021, regulated by the Department of Consumer Protection (DCP), and bettors must be 21. Attorney General William Tong: “Sports event contracts are no different than sports betting.” DCP Commissioner Bryan Cafferelli has said “sports betting may only be offered by legal, licensed sportsbooks.”
Kalshi in Connecticut
- December 2025: DCP ordered Kalshi to stop offering sports contracts.
- August 10, 2026: a federal judge denied Kalshi a preliminary injunction, writing that “the fact that Connecticut law imposes an additional regulatory requirement on Kalshi does not, without more, establish a conflict with federal law.” Kalshi has appealed to the Second Circuit.
- August 26, 2026: Connecticut sued Kalshi, seeking an injunction.
- The CFTC sued Connecticut in April 2026, and Connecticut has moved to dismiss.

The September 2026 orders
On September 10, 2026, DCP issued cease-and-desist orders to “nine prediction markets known to be operating illegally in Connecticut”: Polymarket, Coinbase, Crypto.com, Robinhood, ProphetX, Novig, Webull, Gemini and Underdog Predict. It told them to stop offering sports contracts and to let customers withdraw their funds. Some outlets have reported that a few platforms left Connecticut afterwards, but DCP’s own release doesn’t say so, and we couldn’t confirm it.
Other platforms
We found no Connecticut action against PredictIt. DraftKings and FanDuel don’t offer sports contracts in Connecticut, where they run licensed sportsbooks. Compare every state in our legality tracker.
