A federal judge denied Kalshi's request to block Connecticut from enforcing its gambling laws against the prediction-market exchange, ruling that Kalshi's sports event contracts do not meet the legal definition of a swap. U.S. District Judge Vernon D. Oliver signed the order August 7 in KalshiEX LLC v. Cafferelli, entered on the docket August 10, and Kalshi filed a notice of appeal to the Second Circuit the same day.
The ruling turns on one statutory phrase. Federal law defines a swap by reference to the "occurrence, nonoccurrence, or extent of occurrence" of an event, the hook Kalshi has used nationwide to argue state gambling regulators are preempted by its federal CFTC oversight. Judge Oliver found Kalshi's sports contracts don't fit that language because they pay out based on who wins or a game's point total, an outcome, not an occurrence. His order states plainly that "at bottom, they are sports wagers." As a second, independent basis for the ruling, he added that even if the contracts were swaps, Connecticut's gambling laws would survive because states retain traditional police power over sports wagering, citing the Supreme Court's Murphy v. NCAA decision.
The practical effect: Connecticut's Department of Consumer Protection, which sent Kalshi a cease-and-desist notice in December, can now move to enforce state law against the exchange's sports contracts without a federal injunction standing in the way.
Connecticut lines up with Nevada and Maryland, where courts have already sided with state regulators against Kalshi. It sits squarely against the Third Circuit, which ruled 2-1 in April that the same kind of contracts are swaps and preempt New Jersey law, a ruling this desk covered as Kalshi kept expanding its state-by-state legal fight. Two federal appellate-track rulings now disagree on the exact same legal question, sports event contracts as swaps or wagers, which is the kind of split the Supreme Court eventually gets asked to resolve.
For sportsbooks watching from the licensed side of the line, Kalshi's compliance deadlines and courtroom wins and losses are arriving state by state, not as one national answer. Every ruling either way changes the competitive math for operators paying state taxes and licensing fees for a product a federal exchange can currently offer without either.
One judge's word choice does the work of a whole regulator
Every one of these cases turns on whether "occurrence" and "outcome" are the same thing under a 1930s-era commodities statute never written with sportsbooks in mind. Connecticut's answer was no. New Jersey's appellate panel said yes. Until a higher court picks one meaning for the whole country, prediction markets will keep winning in some states and losing in others, and Kalshi will keep appealing every loss.
