Washington court rules Kalshi's event contracts illegal gambling, operator agrees to geofence
A Washington state court ruled Kalshi's event contracts constitute illegal gambling under state law. The decision targets Kalshi's YES/NO contracts on future event outcomes. Kalshi agreed to implement geofencing restrictions by Aug. 26 to block Washington users from placing bets. The prediction market operator said the pause is overbroad. The ruling follows similar state-level losses for Kalshi in other jurisdictions.
Kalshi must now geofence Washington by Aug. 26 or absorb contract-voiding risk there, adding another state to its growing compliance map. Federal registration is no longer a shield; judges in Wisconsin, Utah, New York, and now Washington have rejected CFTC preemption. The platform's legal bill and operational complexity rise with every additional front. Rival Polymarket holds identical exposure since both share the same federal status that courts keep treating as irrelevant.
The Second Circuit appeal is the only path to a national standard, but that court may not rule before more states file. The platform that builds state-level compliance fastest keeps its market position; the one waiting for a federal shield risks losing it jurisdiction by jurisdiction. New York attorney general sues Kalshi over alleged illegal gambling, pressing the same federal-state conflict one day earlier.
Joins New York, Utah, and Wisconsin in rejecting CFTC preemption and forcing Kalshi into state-by-state geofencing, with Michigan, Illinois, and New Mexico still active fronts.
