Connecticut hits nine prediction markets with cease-and-desist orders
Connecticut regulators issued cease-and-desist orders to nine prediction market platforms on Thursday, September 10, 2026, demanding an immediate halt to advertising, offering, or promoting sports event contracts. The state labeled the operations illegal under Connecticut gaming and unfair practices law. Officials did not publicly name the targeted platforms. The enforcement action comes alongside an ongoing Connecticut lawsuit against Kalshi over similar contracts.
The orders force nine unnamed platforms to choose between pulling Connecticut users or risking state gambling enforcement, regardless of any federal CFTC registration they may hold. For Kalshi, already battling the state in separate litigation, the widened enforcement swell multiplies the pressure before any court resolves whether CFTC designation preempts state gaming law. Operators face immediate geofence costs or potential contempt exposure, while traders in Connecticut hold positions whose legality now depends on a state regulator's say-so.
Each new state action that bypasses or shrinks the federal preemption shield emboldens attorneys general elsewhere. The platforms' legal spend compounds across parallel cases that cannot resolve until the Supreme Court weighs New Jersey's pending petition. A geofence cascade fragments national liquidity before any final ruling lands. New Jersey asks Supreme Court to settle Kalshi sports-contracts fight signals the point where scattered state losses harden into a deliberate push for federal resolution.
Connecticut's multi-front campaign against CFTC-registered sports event contracts, which already includes a separate suit targeting Kalshi and joins parallel state actions in Nevada and Baltimore that the Supreme Court may soon consolidate.
