Summary

Washington bans online gambling. The Gambling Act (RCW 9.46) allows only the activities it lists, and since 2006 knowingly sending or receiving gambling information over the internet has been a class C felony, which the Washington State Gambling Commission says the player commits as well as the operator. The Commission, five members appointed by the Governor plus four legislators who vote only on tribal compacts, licenses card rooms, pull-tabs, bingo, raffles and suppliers, and negotiates Class III compacts with all 29 federally recognised tribes. Sports wagering was authorised in March 2020 only at tribal casinos under amended compacts. Twenty-one tribes have sports wagering appendices and 24 of the 28 casinos on the Commission's list take bets. Mobile betting is allowed only inside a casino's geofenced premises, on an account opened in person. No commercial sportsbook can be licensed; suppliers need a Commission vendor licence costing $2,000 to $30,000 a year. The Lottery may not sell tickets online. The Horse Racing Commission lists seven advance deposit wagering firms, open to adults 21 and over. Tribal gaming pays no state gaming tax. Commercial operators pay local gambling taxes, up to 20% of card room revenue, and a state tax on contests of chance of 1.5%, rising to 1.8% on 1 January 2027. A 2026 law allows betting on in-state college teams with limits, and tribes are amending compacts to adopt it. The Commission says prediction markets are not authorised, and in August 2026 a King County court ordered Kalshi to stop offering sports, election and similar contracts in the state. The Commission reported net gambling receipts of $3.95 billion for the year to June 2024, of which an estimated $2.85 billion was tribal.

Common pitfalls

Treating on-premises mobile betting as online sports betting: a Washington sportsbook app works only inside the tribal casino's geofence, on an account opened there. Assuming a player is safe using an offshore site: the statute covers receiving gambling information, and the Commission says the player breaks the law too. Assuming prediction markets are lawful because they are federally registered: the Commission says they are not authorised and a state court has enjoined Kalshi, though federal preemption is still being argued. Assuming free-to-play social casinos are outside the law: in Kater the Ninth Circuit found virtual chips were a thing of value. Reading the Commission's sports wagering page on college betting as current: the 2026 amendment changed the rules. Reading the $3.95 billion net receipts figure as audited: the tribal share is an estimate and the labelled components add up to $3.71 billion.

Advertising

Advertising permitted
Yes
Affiliate rules
Marketing or promotional affiliates paid a percentage of a tribal operator's or vendor's sports wagering revenue need an ancillary sports wagering vendor licence ($2,000 a year). Promoting unauthorised online gambling can be professional gambling (RCW 9.46.0269), and the Commission warns that websites misrepresent the law to steer players to illegal sites.
Mandatory warnings
Advance deposit wagering advertising: a statement that individuals under 21 may not open, own or have access to an account (RCW 67.16.260(2)(d)).
Penalties for breach
Criminal penalties for professional gambling, and civil injunctions, restitution and civil penalties under the Consumer Protection Act, as sought by the Attorney General against Kalshi.

Restrictions

  • Soliciting or inducing people to take part in gambling that is not authorised is conduct that materially aids gambling, and so professional gambling, a crime ranging from a gross misdemeanour to a class B felony (RCW 9.46.0269(2), 9.46.220 to 9.46.222). No lawful advertising exists for online casino, poker or remote sportsbooks.
  • Tribal sportsbook staff may not advise or encourage patrons to place a wager of any specific type, kind, subject or amount, but general advertising, promotions and answering general questions are allowed (Appendix S, s 5.2.1).
  • All advertising for advance deposit wagering must state that people under 21 may not open, own or have access to an account (RCW 67.16.260(2)(d)).
  • In the Kalshi case the court held that marketing and advertising illegal gambling to Washington consumers is an unfair or deceptive practice under the Consumer Protection Act, and barred Kalshi from advertising the covered wagers.
