Washington splits Kalshi's book: sports and elections geofenced by Aug 19, commodities untouched

A King County Superior Court judge has issued a final order requiring Kalshi to shut down most of its Washington business, after finding the exchange likely broke the state's Gambling Act and Consumer Protection Act by running an unauthorized gambling operation ^[1]. What matters is not that a state won again, but how the order was drawn: it cuts Kalshi's product line in half rather than shutting the venue.

Barred for anyone located in Washington are wagers on sports, elections, politics, entertainment, culture, technology and science, plus "mentions" contracts, where users bet on whether a public figure will say particular words ^[2][3]. Contracts tied to commodities, climate conditions, economics and finance are unaffected and may continue to be offered ^[4]. That is the first clean judicial line between a prediction market operating as a derivatives venue and the same platform operating as a sportsbook, and it was drawn by category, not by legal theory.

The engineering deadlines are short. Kalshi must have an IP-address and residency-based geofence running by August 19 and a broader multi-source geofencing system by September 2 ^[5], a gap of 14 days between the stopgap and the real thing ^[21]. The court also barred advertising the covered contracts in Washington, holding that marketing illegal gambling amounted to "unfair and/or deceptive acts or practices" ^[6]. The state's complaint cites a Kalshi promotional tweet in which a person texts a friend to say they had "found a way to bet on the NFL even though we live in Washington," which the attorney general's office argues shows the company knew it was working around state law ^[8].

Attorney General Nick Brown said Kalshi had "gotten rich promoting wagers on sports, elections, natural disasters" and events tied to the Iran war, and that under the order Kalshi is banned from offering wagers on most of those topics in Washington ^[9]. The word "most" is doing work. Natural disasters sit inside the climate category the order leaves alone ^[4][22], which shows how much of the dispute turns on taxonomy rather than mechanics. The attorney general's office says the restricted categories cover a substantial part of a business "increasingly driven" by sports ^[7].

The order builds on a July 2026 preliminary injunction from Judge John McHale, who found substantial injury to Washington consumers was likely without one, and the Washington Court of Appeals refused Kalshi's request to stay it ^[10][11]. The attorney general sued in March, arguing Kalshi was soliciting illegal bets and advertising in ways that implied the activity was lawful ^[16]. Kalshi's answer has been consistent: it is regulated by the CFTC and state gambling statutes are preempted ^[17].

That argument is being fought at the federal level on a different track. Two days before the Washington order, the CFTC invoked emergency authority to direct Kalshi to keep trading in line with the Commodity Exchange Act's core principles, acting on the exchange's own notification of a market emergency after New York sued ^[12]. The agency's position is that event contracts are interstate derivatives beyond state gaming law; Washington's is that each bet stakes money on a contingent event and therefore meets the statutory definition of gambling ^[13]. The CFTC has sued nine states on the question, starting with Illinois, Arizona and Connecticut and continuing through Wisconsin and Minnesota, which it sued within hours of that state's ban taking effect ^[14]. President Trump has backed the agency, calling state officials who oppose prediction markets "SCUM" ^[15].

Watch the September 2 multi-source deadline, because a residency-plus-IP filter is cheap and a multi-signal one is not, and every additional state order compounds the cost. Watch whether other courts adopt Washington's commodities carve-out as a template rather than an all-or-nothing injunction; courts in several states have already issued comparable restrictions ^[20]. The litigation itself is not over ^[19].
