Connecticut judge denies Kalshi injunction, rules sports contracts not swaps
Judge Vernon Oliver in Connecticut denied Kalshi's request for a preliminary injunction on August 10, ruling the platform's sports event contracts are not swaps and would gain no federal protection from state gambling laws even if they were. The decision rejects every major argument Kalshi advanced and quotes a prior Nevada ruling against Crypto.com's sports contracts. Oliver called the contracts wagers. Kalshi cannot offer them in Connecticut while litigation proceeds.
Kalshi's federal preemption shield is collapsing in federal courtrooms, not just state ones. Each new loss forces the platform to geofence another market or absorb penalties while fighting market by market. The Connecticut ruling is particularly damaging because Judge Oliver reached the same wager conclusion as his Nevada counterpart, creating a cross-jurisdictional pattern that other judges can cite. Traders holding contracts in affected states face sudden voiding risk if enforcement follows.
For Polymarket, the identical CFTC registration means identical exposure in every state that copies this playbook. The Second Circuit appeal remains the only path to a national standard, but that court may not rule before more states file. Legal spend and operational complexity rise with every additional front. The federal registration Kalshi built its expansion on is increasingly just a federal label, not a shield.
