Washington State Court Rules to Ban Multiple Event Contracts by Kalshi, Must Implement Geoblocking by August 19
The King County Superior Court in Washington State issued a final ruling requiring the prediction market platform Kalshi to cease offering event contracts related to sports, elections, politics, entertainment, culture, technology, science, and "person mentions" to the state.
It also prohibits promoting related products to consumers in the state.
Kalshi must implement geoblocking through IP addresses and user residences by August 19, and upgrade to a multi-source geofencing system by September 2.
Contracts related to commodities, climate, economy, and finance are not included in this ban.
Kalshi previously requested a stay of the ban, but was denied by the Washington State Court of Appeals.
Market mechanisms indicate that state gambling laws have led to the geographic isolation of certain prediction market operations, concentrating funds and trading volume in states where operations are permitted and compliant; the beneficiaries are traditional gambling channels and compliant contracts protected within the state, while the pressured parties are platform users and trading volume reliant on sports and political contracts.

As a CFTC-regulated event contract platform, Kalshi has previously argued against state gambling laws using federal preemption, but this final ruling from the Washington State Court continues the trend of multiple states treating sports and political contracts as illegal gambling, explicitly requiring technical geoblocking.
From a capital perspective, the platform is forced to invest in geofencing and compliance resources to retain some business while shrinking high-traffic categories; the motivation is to avoid ongoing fines and a complete ban, strategically prioritizing the national accessibility of commodity and financial contracts.
Similar cases can be seen in states like New York, Massachusetts, and Michigan, which have imposed similar restrictions on Kalshi; the current prediction market is in a phase of increasing conflict between federal regulation and state gambling laws.
The structural judgment reflects regulatory changes: state courts are redefining the boundaries of event contracts through bans and geotechnical requirements, whereby when state law defines most event contracts as gambling, platforms must achieve state-level isolation through technical means, or face enforcement and fines.
