Enforcement: How hard does the regulator enforce?

Enforcement in Washington operates on the same two layers common to us-state jurisdictions: a federal overlay (Wire Act exposure for interstate wagering absent a compact, UIGEA financial-blocking exposure) and the state's own Gambling Act (RCW 9.46), enforced this cycle with unusual intensity. The Attorney General sued Kalshi (filed March 27, 2026) alleging its prediction-market sports and event wagers constitute illegal gambling absent tribal-compact authorization; a King County judge found likely violation on July 21, 2026, entered a preliminary injunction, and on August 13, 2026 ordered Kalshi to cease Washington operations on sports, politics and entertainment topics, with the Court of Appeals denying a stay. This action is confirmed and T1-sourced, resting on the durable statutory Gambling Act rather than fragile guidance. Kalshi has countered, via a single T2 source not yet corroborated by a T1 filing, that the state is engaged in selective non-enforcement against comparable prediction-market operators including Crypto.com's "OG" product, with the dispute pending Ninth Circuit jurisdictional review; this allegation should be read as probable, not confirmed. The clearest revocation-risk driver for any non-compliant operator is unlicensed prediction-market activity aimed at Washington residents, which the state has now shown it will litigate aggressively under the existing Gambling Act framework.
