The bill, titled the "sports wagering integrity act," amends RCW 9.46.038, 9.46.0364, 9.46.0368, and 9.46.037 and creates new sections to define and regulate sports wagering. It establishes a statutory definition of sports wagering that covers professional, collegiate, Olympic/international, and electronic/esports events, combinations of those, and portions of those events, while excluding wagers on horse racing authorized under chapter 67.16 RCW. It also bars wagering on the named performance or nonperformance of any specifically named individual participant in a collegiate sport who is enrolled at an in-state institution, and excludes minor league sports from the definition of professional sports for wagering purposes. The bill authorizes tribal class III gaming compacts to be amended, at a federally recognized tribe’s request and subject to the Indian Gaming Regulatory Act and RCW 9.46.360, to permit sports wagering on Indian lands. Compact amendments must address licensing, fees for the gambling commission’s regulation, how sports wagering will be conducted and regulated, criminal enforcement issues including money laundering and sport integrity, information sharing between the commission and the tribe, and responsible and problem gambling. Sports wagering conducted under an authorized class III compact is treated as an authorized gambling activity and as authorized bookmaking not subject to civil or criminal penalties under RCW 9.46.225. The bill also authorizes transmission of gambling information over the internet for such tribal sports wagering, provided wagers placed and accepted at a tribe’s facility are made while the customer is physically present on the tribe’s gaming premises. The act creates new criminal prohibitions related to influencing sporting events or wagering and makes violations a class C felony under RCW 9A.20.021; listed offenses include offering or accepting value to influence outcomes, trading on nonpublic information, placing wagers after obtaining nonpublic knowledge of bribery or offers related to events, and making threats related to events. It bars anyone who threatens a sports official, coach, or participant from placing sports wagers. The bill includes a severability clause. Important context is missing from these excerpts: the specific chapter reference where the term "this chapter" is used is not restated, there are editorial markings suggesting text changes, and no effective dates, implementation deadlines, or detailed procedures for negotiating or approving compact amendments are provided in the extracted facts.

If passed, the bill would open a new revenue and operational path for federally recognized tribes in Washington to offer sports betting on Indian lands by amending their class III compacts to cover professional, collegiate (with limits), Olympic/international, and esports events. Tribes would be required to negotiate compact terms covering licensing, fees to cover the state gambling commission’s regulation, how betting is run, criminal enforcement cooperation, and responsible-gambling measures, so tribal casinos could gain new income but would also take on compliance costs and responsibilities to meet commission requirements; bets placed under those compacts would be treated as authorized bookmaking and not subject to the cited state penalties. For bettors and sports personnel the bill tightens risks and limits: wagers on horse racing and minor league sports are excluded, named in-state college student athletes cannot be bet on, and anyone who threatens an official, coach, or participant may be barred from placing bets; the bill also creates felony offenses for bribery, insider trading, or other actions that influence outcomes. The measure allows transmission of betting information over the internet when tied to tribal wagering but requires a bettor to be physically at a tribal facility to place a wager; however, the text does not specify implementation dates, fee amounts, or the compact approval process, so timing, exact costs, and final operational rules remain uncertain.
