Connecticut Sues Kalshi Seeking Injunction Over Sports Prediction Contracts
TL;DR — Connecticut sued Kalshi for unlicensed sports wagering through prediction contracts, seeking an injunction after a December 2025 cease-and-desist. The state equates them to betting requiring consumer safeguards; Kalshi claims exclusive CFTC oversight as swaps. Appeals and a parallel CFTC suit against the state are pending.
SCCG Take — This litigation tests federal preemption limits against state gaming enforcement, creating compliance uncertainty for prediction platforms until appellate clarity emerges.
Connecticut has filed suit against Kalshi to block the platform from offering sports-related prediction contracts to state residents, alleging unlicensed sports wagering. Attorney General William Tong, Gov. Ned Lamont and Department of Consumer Protection Commissioner Bryan T. Cafferelli announced the action, requesting a court injunction.
The state contends that Kalshi’s yes-or-no contracts tied to sports outcomes, including team or player wins, season win totals, league rankings, point totals, spreads and individual statistics, constitute gambling subject to Connecticut licensing and consumer protections. Tong said these offerings are no different than sports betting and receive no special federal shield. “Sports event contracts are no different than sports betting and are not magically shielded by federal law from Connecticut’s commonsense consumer protection laws,” Tong said. “These laws exist for a reason — to protect minors, to prevent problem gambling, to ensure your money is safe and your personal information is protected.”
As reported by Yogonet International, the lawsuit follows a December 2025 cease-and-desist order from the Department of Consumer Protection’s Gaming Division against Kalshi and two other platforms. That order required them to stop unlicensed online gambling and withdraw held funds. Cafferelli noted the department has tracked prediction markets since inception with concern over public impacts.
Court Filings and Competing Regulatory Claims
Kalshi challenged the earlier order in federal court, arguing its products are swaps regulated exclusively by the Commodity Futures Trading Commission. U.S. District Judge Vernon Oliver denied Kalshi’s preliminary injunction request earlier this month. The company appealed to the Second Circuit Court of Appeals. A judge denied Kalshi’s ex parte relief Wednesday, and an in-person status conference is scheduled for September 17.
The CFTC has sued Connecticut and two other states on the same federal-preemption grounds. Connecticut has filed a motion to dismiss that action. Gov. Ned Lamont said the markets place consumers, young people, student athletes and those with gambling addiction at serious risk, adding that the operators prioritize profits over people. Kalshi’s head of litigation posted on social media: “Connecticut just filed this lawsuit to shutdown @Kalshi immediately, but they’re okay with other prediction markets operating there in the meantime. This is the latest in a line of arbitrary and inconsistent enforcement by the states, which shows this has nothing to do with…”
The Open Question of Classification
The parallel state and federal lawsuits expose a direct clash over whether these contracts fall under commodities or gaming rules. Resolution will determine licensing obligations and enforcement consistency for platforms operating similar products.

This case will decide whether states can regulate prediction markets as wagering or if federal commodity oversight preempts them.
We're watching this closely because it cuts to the heart of how prediction markets get classified and who regulates them. If Connecticut wins, every state could assert jurisdiction over event contracts, fracturing compliance. If Kalshi prevails, the CFTC becomes the sole gate, and state gaming frameworks lose a category of product they've always policed.
