As of my last update in early 2023, sports betting in Washington State is limited. The state does not allow traditional sports betting at retail locations or online as other states do following the 2018 Supreme Court decision that struck down the Professional and Amateur Sports Protection Act (PASPA).
However, the state does permit sports betting on tribal lands. Some Washington tribes have opened sportsbooks at their casinos under the terms of their compacts with the state. These sportsbooks typically operate under the same regulations as other casino games offered by the tribes.
It’s important to note that the legal landscape can change, and there have been discussions and efforts to expand sports betting in the state. For the most current information, you should check with the Washington State Gambling Commission or the latest state laws and regulations.
