Connecticut sued Kalshi on August 26, 2026, seeking a court injunction to stop the exchange from offering sports event contracts to Connecticut residents. Attorney General William Tong, the Department of Consumer Protection and Governor Ned Lamont say the contracts are unlicensed sports wagers, while Kalshi argues they are federally regulated derivatives under CFTC oversight.
What did Connecticut announce against Kalshi?
The Connecticut Attorney General’s August 26 release said the state filed suit against Kalshi and is seeking an injunction to block what it describes as unlicensed sports wagering in Connecticut. The release identifies the case as part of a broader state effort to enforce Connecticut’s gaming laws against sports event contracts offered through prediction-market platforms.
Kalshi operates an online event-contract exchange where users trade yes-or-no contracts tied to future outcomes. Connecticut’s release said Kalshi’s sports contracts include outcomes such as whether a team or player will win a game or series, season win totals, league rankings, point totals, point spreads and player statistics. The state characterizes those products as gambling, not merely financial-market instruments.
Tong put the state’s theory plainly in the announcement: “Sports event contracts are no different than sports betting and are not magically shielded by federal law from Connecticut’s commonsense consumer protection laws.” The state is also arguing that Connecticut’s regulatory system is designed to protect minors, problem gamblers, customer funds and personal information.
Why is Connecticut treating the contracts as sports betting?
Connecticut’s position is that Kalshi’s sports event contracts compete with licensed sports wagering without operating inside the state’s gaming framework. Lamont tied the lawsuit to the state’s 2021 legalization of sports wagering, saying the goal “was to create a safe, responsibly regulated market for Connecticut consumers, not to open a free-for-all on sports betting.”
The Department of Consumer Protection has framed the case as both a licensing dispute and a consumer-protection dispute. In the August 26 announcement, DCP Commissioner Bryan T. Cafferelli said prediction markets are presenting sports wagering as investment activity while operating outside Connecticut’s gaming standards. His statement said the state believes the platforms target minors and individuals who have chosen to exclude themselves from gambling activity, and do not comply with technical standards meant to protect customer money and data.
Those are allegations from Connecticut officials, not findings by a court in the new state case. The central legal question is whether Connecticut can apply its gaming laws to Kalshi’s sports contracts, or whether the Commodity Exchange Act and CFTC oversight limit state enforcement.
How did the dispute begin?
The fight started formally on December 3, 2025, when the DCP Gaming Division ordered KalshiEX LLC, Robinhood Derivatives LLC and Crypto.com Derivatives North America LLC to cease and desist from conducting unlicensed online gambling in Connecticut. DCP’s public release that day said the orders covered advertising, offering, promoting or otherwise making available sports event contracts or other unlicensed online gambling to Connecticut residents. The agency also ordered the platforms to allow Connecticut residents to withdraw funds held by the platforms.
Kalshi sued the same day in federal court. The Justia docket for KalshiEX LLC v. Cafferelli, No. 3:25-cv-02016 in the U.S. District Court for the District of Connecticut, lists the filing date as December 3, 2025, and identifies the defendants as Cafferelli, Kristofer Gilman, the Connecticut Department of Consumer Protection and Tong. The docket lists the nature of the suit as securities and commodities, with a Commodity Exchange Act cause of action.
Kalshi’s federal case sought to stop Connecticut officials from enforcing the state’s gaming laws against the exchange. Its argument rests on KalshiEX’s federal status as a designated contract market. The CFTC announced on November 4, 2020, that it had issued an order granting KalshiEX LLC designated contract market status under the Commodity Exchange Act and CFTC Regulation 38.3(a).
What did the federal judge decide?
United States District Judge Vernon D. Oliver denied Kalshi’s motion for a preliminary injunction in an order dated August 7, 2026, and posted by Justia as ECF No. 94 in KalshiEX LLC v. Cafferelli. The order rejected Kalshi’s bid to block Connecticut enforcement while the federal case proceeds.
Oliver concluded that Kalshi’s sports event contracts were not swaps under the Commodity Exchange Act and therefore did not fall within the CFTC’s exclusive jurisdiction. The court also held that federal law did not preempt Connecticut’s authority to regulate sports wagering. In the court’s formulation, the disputed contracts were based on results of sporting contests rather than events that, by their nature, carry embedded financial, economic or commercial consequences.
The order also said Kalshi had not shown irreparable harm or that the balance of equities and public interest favored an injunction. The court noted Connecticut’s asserted interest in enforcing its gaming laws and said harm to Kalshi users from unwinding existing contracts did not outweigh the state’s and public’s enforcement interests.
Kalshi then sought short-term relief pending appeal. In a separate Justia-posted order, ECF No. 99, Oliver again denied relief, saying Kalshi had not made the required showing for an injunction pending appeal. The Connecticut Attorney General’s August 26 release said Kalshi has appealed to the Second Circuit Court of Appeals.
How large is Kalshi’s business?
Kalshi’s state-by-state litigation is unfolding as the company has become one of the most valuable firms in the prediction-market sector. The Block reported on May 7, 2026, that Kalshi reached a $22 billion valuation after a $1 billion raise led by Coatue, and described the company’s trading volume as running at a $178 billion annualized pace.
Those figures matter because the Connecticut dispute is not limited to a narrow product test. Sports event contracts have become central to the policy fight over whether prediction markets are regulated primarily as financial exchanges, gambling operators, or both depending on the product and jurisdiction. Connecticut’s lawsuit targets Kalshi’s ability to offer those contracts in one state, but the federal appeal could shape how other states evaluate similar enforcement actions.
What does Kalshi say?
Kalshi has argued that state enforcement creates uneven treatment for federally regulated exchanges. In coverage of the Connecticut lawsuit, The Block quoted Jovy Dedaj, Kalshi’s head of litigation, calling the state’s move “arbitrary and inconsistent enforcement” and saying, “This unequal treatment is exactly why federal oversight is necessary.”
That position is consistent with Kalshi’s federal litigation strategy: the company says its products are subject to federal commodities law, while Connecticut says sports contracts that function like sports bets remain subject to state gaming law. The CFTC has also taken the view that states are intruding on federal jurisdiction. Connecticut’s August 26 release said the CFTC has sued Connecticut and two other states and that Connecticut has moved to dismiss the CFTC’s lawsuit.
What happens next?
The next major venue is the Second Circuit, where Kalshi is appealing Oliver’s refusal to block Connecticut enforcement. At the same time, Connecticut’s new suit seeks a state-court injunction against Kalshi’s sports event contracts in Connecticut.
The stakes are practical as well as legal. If Connecticut can enforce its gaming laws against Kalshi’s sports markets, other states may have a stronger path to treating similar contracts as unlicensed sports wagering. If Kalshi or the CFTC prevails on federal preemption, prediction-market operators would gain a stronger argument that CFTC-regulated exchanges can list sports event contracts without complying with each state’s sportsbook licensing regime. The next concrete milestone is Kalshi’s appeal in the Second Circuit, which will test whether Judge Oliver’s Connecticut ruling survives appellate review.
