Sports betting in Washington state is legal but operates under one of the most restrictive frameworks in the country. Unlike the majority of states that allow statewide mobile wagering from anywhere, Washington permits sports betting exclusively on the lands of federally recognized Native American tribes. Bettors must be physically present inside a tribal casino’s property to place any wager, whether in person at a counter or via an app geofenced to casino grounds. Governed by the Washington State Gambling Commission, the market launched in September 2021 and has grown to more than 17 retail sportsbook locations statewide. As of June 11, 2026, Washington bettors can also legally wager on in-state college teams for the first time under the newly effective Sports Wagering Integrity Act (SB 6137).

Top Sportsbooks in Washington
Retail Sportsbooks in Washington
All legal sportsbooks in Washington are located at tribal casinos. Roughly half of the state’s more than 30 tribal gaming locations now offer sports betting. Several have partnered with national brands such as BetMGM, DraftKings, FanDuel, and Caesars, while others operate proprietary or white-label systems. A few casinos offer accompanying apps for on-premises use. Note that remote registration is not allowed — you must visit the casino in person to register. The Sports Wagering Integrity Act, effective June 11, 2026, also updated the state’s tribal wagering-acceptance rules, which industry reporting indicates paves the way for individual properties to eventually offer bettors access to more than one sportsbook brand — though rollout depends on each tribe amending its own gaming compact and is not yet universal across every location listed below.

Sports Betting Laws and Regulations in Washington
Washington’s original sports betting law (HB 2638) restricts all wagering — retail and mobile — to the physical premises of tribal casino properties. This means that while some casinos offer mobile apps, those apps are geofenced and only functional on tribal land. Statewide remote wagering from home is not permitted.
Key legal provisions include:
- Sports betting is exclusive to federally recognized Native American tribes that have amended their Class III gaming compacts
- Wagers may be placed only while the bettor is physically present on tribal gaming property
- Remote registration is not allowed — bettors must register at the casino in person
- Betting on in-state college teams (University of Washington Huskies, Washington State Cougars, Gonzaga, etc.) is permitted as of June 11, 2026 under SB 6137
- Player prop bets on the performance of any individual athlete enrolled at a Washington-based college are prohibited
- Wagers on a coach’s in-game decisions (substitutions, timeouts, replay challenges) and on officiating calls in Washington collegiate contests are also prohibited
- Esports betting is permitted at tribal sportsbooks
- The Washington State Gambling Commission oversees all sports wagering activity and tribal compact compliance
- Tribes pay no commercial gaming taxes on sports betting revenue; participating tribes share regulatory costs among themselves
Washington’s college betting expansion became law through SB 6137, the Sports Wagering Integrity Act, which Gov. Bob Ferguson signed on March 30, 2026 after it cleared the House 70-26 and the Senate 43-6. The law took effect June 11, 2026 — meaning bettors missed the 2026 NCAA Tournament window but can now legally bet game lines and totals on Washington college teams at tribal sportsbooks. A companion House proposal (HB 2205, later reintroduced as HB 2526) sought similar changes plus explicit multi-operator access per casino, but that bill stalled in the House Rules Committee and did not pass; SB 6137 became the vehicle that actually reached the governor’s desk. The new law also adds gross misdemeanor and felony penalties for match-fixing and for threatening athletes, coaches, or officials in connection with a wager.
Taxes on Sports Betting Winnings in Washington
Washington is one of the few states with no state income tax, which is a significant financial advantage for sports bettors. However, federal tax obligations still apply to gambling winnings.
- Washington state income tax: None — Washington does not levy a personal income tax, meaning sports betting winnings are not subject to state-level taxation
- Federal income tax: All gambling winnings are taxable income under federal law. The IRS requires winnings to be reported, and sportsbooks are required to withhold 24% for federal taxes on net winnings of $5,000 or more (when the payout is at least 300x the wager)
- Form W-2G: Issued for qualifying gambling wins; must be reported on your federal tax return
- Operator taxes: Tribal casinos do not pay a standard commercial gaming tax to the state; instead, participating tribes split regulatory costs associated with operating sports wagering
The absence of a state income tax makes Washington one of the more bettor-friendly states from a tax perspective, even if the betting framework itself is among the most restrictive in the country.

FAQs About Sports Betting in Washington
Is sports betting legal in Washington state?
Yes, sports betting is legal in Washington, but only at tribal casino locations. Bettors must be physically present on tribal gaming property to place any wager — whether in person or via a casino’s mobile app. There is no statewide mobile betting from home.
Can I use FanDuel or DraftKings in Washington?
Yes, but only at specific tribal casino locations. FanDuel is the sports betting partner of Suquamish Clearwater Casino Resort, while DraftKings operates at Quil Ceda Creek Casino and Tulalip Resort Casino. You must be physically present at these properties to use the apps.
How many retail sportsbooks are there in Washington?
There are 17 tribal casino locations in Washington that currently offer legal sports betting, making it one of the larger retail-only markets in the country by sheer number of physical locations.
What is the minimum betting age in Washington?
There is no single statewide minimum age — it varies by tribal casino. Some properties allow bettors who are 18+, while others require patrons to be 21 or older. Always confirm with your chosen casino before visiting.
Can I bet on Washington Huskies or Washington State Cougars games?
Yes. As of June 11, 2026, SB 6137 (the Sports Wagering Integrity Act) lifted Washington’s long-standing ban on in-state college wagering. You can now bet game lines, spreads, and totals on the Huskies, Cougars, Gonzaga, and other Washington-based college teams at tribal sportsbooks. Individual player prop bets on athletes enrolled at Washington schools remain illegal, as do wagers tied to a coach’s in-game decisions (substitutions, timeouts, replay challenges) or officiating calls in games involving Washington college teams.
Did SB 6137 also allow multiple sportsbook apps at the same casino?
SB 6137 revised the state’s tribal wagering-acceptance language, and some industry reporting expects it to eventually open the door to bettors accessing more than one sportsbook brand at a given property. However, actual rollout depends on each tribe negotiating and amending its own gaming compact, so a separate House proposal (HB 2205/HB 2526) that would have explicitly mandated multi-operator access at every casino stalled in committee and did not pass. Check with your specific casino for current app availability.
Will Washington ever allow statewide mobile sports betting?
This remains uncertain. The state legislature has consistently rejected efforts to expand betting beyond tribal lands, and even the 2026 college-betting expansion (SB 6137) only broadened what can be wagered on within tribal properties — it did not touch the on-premises geofencing requirement. Full statewide mobile wagering would require significant changes to existing tribal compact law.
Are there any taxes on sports betting winnings in Washington?
Washington has no state income tax, so your winnings are not subject to state-level taxes. However, federal income tax rules still apply — all gambling winnings must be reported to the IRS, and withholding applies on larger qualifying wins.
