Washington Sports Betting: A Comprehensive Guide
Sports betting in Washington has a unique landscape, shaped by state laws that place tribal casinos at the heart of the industry. This guide provides a comprehensive overview of everything you need to know about wagering on your favorite sports in the Evergreen State, from the legal intricacies to the best places to bet.
Current Legal Status and History
Sports betting was officially legalized in Washington in March 2020 with the passage of House Bill 2638. Governor Jay Inslee signed the bill into law, making Washington the first state in the US to legalize sports wagering in that year. However, the law came with a significant condition: all sports betting must take place at tribal casinos. The first legal sports bet was placed in September 2021 at the Snoqualmie Casino.
This tribal-exclusive model means that while sports betting is legal, it is not as widely accessible as in other states with open, competitive markets. All betting, whether done in person at a retail sportsbook or via a mobile app, must be initiated and completed within the physical boundaries of a participating tribal casino's land. This has led to a market dominated by retail sportsbooks, with mobile betting serving as a convenient on-property feature rather than a statewide option.
As of early 2026, there is ongoing discussion among lawmakers about expanding the current framework. Proposed legislation is considering the possibility of allowing online sports betting to be accessible from anywhere in the state, as well as lifting the ban on betting on in-state collegiate teams. However, these changes are still in the proposal stage and have not been enacted into law.
Available Sportsbooks and Their Features
Washington's sports betting scene is a mix of nationally recognized brands and casino-specific sportsbooks, all operating in partnership with the state's tribal casinos. Here's a look at the major players and where you can find them:
- DraftKings Sportsbook: One of the giants in the US sports betting market, DraftKings has partnered with the Tulalip Resort Casino and the Quil Ceda Creek Casino. Bettors at these locations can use the familiar DraftKings app and interface to place their wagers.
- FanDuel Sportsbook: Another industry leader, FanDuel, has a partnership with the Suquamish Clearwater Casino Resort. Visitors can enjoy FanDuel's user-friendly platform and extensive betting markets.
- BetMGM Sportsbook: BetMGM has a strong presence through its partnership with the Emerald Queen Casino, which has locations in both Tacoma and Fife. Their mobile app is known for its wide range of betting options and promotions.
- Caesars Sportsbook: Caesars has established itself with multiple partnerships, including the Muckleshoot Casino, Spokane Tribe Casino, and Chewelah Casino. The Caesars Sportsbook app offers a premium betting experience with a robust rewards program.
- Betfred Sportsbook: This UK-based bookmaker has partnered with the Silver Reef Casino Resort, bringing its international expertise to the Washington market.
- Unibet Sportsbook: Unibet offers its services at the Swinomish Casino & Lodge, providing another option for bettors in the northern part of the state.
Many other casinos, such as Snoqualmie Casino, Angel of the Winds Casino Resort, and Ilani Resort, operate their own branded sportsbooks, often powered by technology from providers like IGT and Kambi.
Types of Bets Available
Bettors in Washington have access to a wide variety of wager types, similar to what you would find in other established betting markets. These include:
- Moneyline: A straightforward bet on which team will win the game.
- Point Spread: A bet on the margin of victory. The favored team must win by a certain number of points, while the underdog can win outright or lose by less than the spread.
- Totals (Over/Under): A bet on the total combined score of both teams in a game.
- Parlays: A single bet that links together two or more individual wagers for a higher payout. All legs of the parlay must win for the bet to be successful.
- Teasers: A type of parlay where you can adjust the point spread or total in your favor in exchange for a lower payout.
- Futures: A long-term bet on an event that will happen in the future, such as which team will win the Super Bowl.
- Prop Bets: Bets on specific occurrences within a game that may not be tied to the final outcome, such as which player will score the first touchdown.
- Live Betting: Placing bets on a game while it is in progress, with odds that update in real-time.
It is important to note that Washington law prohibits betting on games involving in-state college teams. This means you cannot wager on teams like the Washington Huskies or the Washington State Cougars.
Tax Implications for Winnings
Sports betting winnings are considered taxable income in the United States. In Washington, you are required to report any gambling winnings to the IRS. If you win more than $600, the sportsbook may issue you a Form W-2G. For larger wins, typically over $5,000, the sportsbook is required to withhold 24% of your winnings for federal taxes.
Washington state does not have a state income tax, so you will not have to pay additional state taxes on your winnings. However, it is always advisable to keep detailed records of your wins and losses for tax purposes and to consult with a tax professional for personalized advice.
Mobile vs. Retail Betting Options
The primary distinction in Washington's sports betting market is the on-property requirement for all wagers. This blurs the line between mobile and retail betting.
- Retail Betting: This is the traditional way to bet, where you go to a physical sportsbook counter or kiosk at a casino, and a ticket writer places your bet for you. You receive a physical betting slip.
- Mobile Betting (On-Property): Many of the tribal casinos with sportsbook partners allow you to use the corresponding mobile app (e.g., DraftKings, FanDuel) to place your bets. However, you must be physically located on the casino's property for the app to work. Geolocation technology is used to ensure compliance. This offers the convenience of betting from anywhere within the casino resort, such as a restaurant or hotel room, without having to visit the sportsbook itself.
There is currently no option for statewide mobile betting from the comfort of your own home, as is available in neighboring Oregon. If you want to bet on sports in Washington, a trip to a tribal casino is a necessity.
