Kalshi Asks Federal Appeals Court to Block Connecticut From Enforcing Gambling Laws Against It

Kalshi has taken its fight with Connecticut regulators to the next level, asking the 2nd U.S. Circuit Court of Appeals in New York to block the state from enforcing its gambling laws against the prediction market operator while the company’s appeal plays out. KalshiEX LLC filed the emergency motion Monday, just days after a federal district judge in Hartford declined to shield the company from Connecticut’s Department of Consumer Protection.

The move is the latest escalation in a legal battle that has forced courts across the country to wrestle with a central question: are Kalshi’s sports event contracts federally regulated financial instruments, or are they illegal sports bets dressed up in commodities-trading language? Connecticut’s answer, at least so far, has been the latter.

How the Case Got Here

Kalshi first sued Connecticut regulators back in December after the state issued the company a cease-and-desist letter over its sports-related event contracts. That lawsuit sought a preliminary injunction that would have barred Connecticut from enforcing its gambling statutes against Kalshi while the underlying legal questions were sorted out.

U.S. District Judge Vernon D. Oliver rejected that request on Aug. 10, ruling that Kalshi’s sports-event contracts don’t qualify as “swaps” under the Commodity Exchange Act — the federal law Kalshi has leaned on in state after state to argue it’s exempt from local gambling oversight. Oliver went further, adding that even if the contracts were properly classified as swaps, Connecticut’s gambling laws still wouldn’t be preempted by federal commodities law. In his written opinion, Oliver notably likened parlay-style sports contracts to casino gaming rather than legitimate financial hedging products.

Kalshi didn’t stop there. The company asked Oliver for an emergency injunction pending its appeal to the 2nd Circuit — essentially a stopgap to keep operating in Connecticut while the higher court reviews the case. Oliver denied that request too on Aug. 15, writing that Kalshi had “not made a strong showing of success on the merits” and noting that three of the company’s four arguments had already been considered and rejected in the earlier preliminary injunction ruling.

What Kalshi Is Asking the Appeals Court For

With the district court avenue exhausted, Kalshi turned directly to the 2nd Circuit this week, filing an emergency motion asking the appellate court to halt Connecticut’s enforcement authority while the underlying appeal is fully briefed and decided. Connecticut opposed the request on Tuesday, asking the court to deny emergency relief and give Attorney General William Tong’s office until Aug. 24 to file a complete response.

The stakes for Kalshi extend well beyond Connecticut. Oliver’s ruling that the company’s sports markets aren’t exempt from state gambling law — combined with the denial of emergency relief — potentially clears the way for as many as nine states to pursue their own enforcement actions against the platform. Connecticut’s Tong could follow the path already taken by New York Attorney General Letitia James, who sued Kalshi outright after New York courts similarly denied the company’s bid for a preliminary injunction.

The Bigger Picture for Prediction Markets

Kalshi has built its business on the argument that its contracts — including ones tied to sports outcomes — are federally regulated derivatives that fall under the jurisdiction of the Commodity Futures Trading Commission, not state gambling regulators. That argument has drawn pushback from state officials and traditional sportsbook operators alike, who see it as a way to offer sports-betting-style products without the licensing, taxation, and consumer protections that regulated sportsbooks must follow.

How the 2nd Circuit rules on this emergency motion could shape how aggressively other states move against Kalshi and similar prediction market operators in the months ahead. For now, the company remains in legal limbo in Connecticut, and bettors weighing prediction markets against traditional sportsbooks should watch how this plays out before assuming these platforms operate with the same regulatory footing.
