The cryptocurrency event-betting platform Kalshi has been banned from offering a wide range of event contracts in the state of Washington—from sports and elections to technology and science. King County Superior Court Judge John McHale rejected the company's argument that federal commodity market legislation takes precedence over the state's gambling law.
According to the ruling, Kalshi is prohibited from offering state residents contracts related to sports, elections, politics, entertainment, culture, technology, and science. Contracts tied to commodities, climate, economy, and financial indicators were not banned—an exception was made for them.
The State Attorney General's Position
Washington State Attorney General Nick Brown commented on the decision on social media X, stating that state authorities are holding Kalshi accountable for operating illegal gambling activities and cited a recent court decision in support of this position.
The ruling orders the company to phase out access for users from Washington. By August 19, a basic geofencing system (a technology for creating a virtual perimeter around a real geographical object) based on IP addresses and user residence data must be implemented.
By September 2, a multi-layered geofencing system from GeoComply needs to be deployed.
These measures should eliminate the possibility of state residents purchasing contracts subject to the court ban.
The Essence of the Court Proceedings
The signed order formalizes the terms of the preliminary injunction that McHale issued back in July. The judge concluded that the Commodity Exchange Act does not preempt Washington's gambling law, and also noted that the state presented sufficient grounds for the likely satisfaction of claims under three state laws.
Kalshi insists that exclusive jurisdiction over its business lies with the Commodity Futures Trading Commission (CFTC). The Washington State Court of Appeals rejected the company's motion to stay the injunction pending appeal.
The dispute between Kalshi and state authorities over the status of event contracts has long extended beyond a single court case: the company is simultaneously defending its business model in several jurisdictions, appealing to federal derivatives market regulation. The Washington court decision essentially formalizes a distinction: contracts tied to financial and commodity indicators remain outside the ban zone, while contracts on political, sports, and cultural events fall under regional gambling legislation.
The further development of the situation will depend on the outcome of the appeal and on how similar disputes in other states influence the general judicial practice regarding prediction markets.
AI Opinion
From the perspective of machine data analysis, the Kalshi case in Washington is not the first episode of its kind: a similar scenario has already unfolded in Massachusetts, where the company faced a lawsuit over unlicensed sports betting. The repetition of the conflict in different states points to a systemic problem: the federal status of an exchange under CFTC supervision does not guarantee a uniform legal framework at the state level, and each jurisdiction is attempting to draw its own line between an "event contract" and a "game of chance."
A technical aspect remaining behind the scenes of the article is the very architecture of geofencing. The transition from IP filtering to a multi-layered GeoComply system within two weeks indicates that regulators are demanding not formal, but actual user exclusion, which is technically more complex for a platform with international reach than a simple address block. Will this model—a federal license plus targeted state bans—remain viable in the long term, or will the matter eventually reach the federal Supreme Court?
