Is Washington Sports Betting Legal?

State-regulated sports betting in Washington became legal in 2020 when HB2638 was passed. The law allows any federally recognized Native Tribe to offer sports betting, but tribes must first negotiate their compacts with the state.

Tribes are permitted to offer both retail and in-person sports betting in Washington. However, the law also stipulates that any gambling activity must take place on tribal land. Although mobile betting is allowed, it can only be offered while people are physically on a licensed premises, so essentially, all domestic sports betting in the state is retail.

Conversely, offshore betting operators offer online sports gambling accessible from any location within the state. These sites are based offshore and do not fall under state or federal jurisdiction. While these offshore platforms are fully licensed and regulated, their oversight comes from overseas organizations rather than the state.

While your winnings won’t be taxed when gambling at tribal casinos, tax may be factored into the odds. For this reason, odds may be more competitive with one of our recommended offshore sports betting operators.

Best Sports Teams to Bet on in Washington

Those from and living within the Evergreen State are hugely proud to boast four professional sports teams. Washington state sports betting fans can bet on any of these teams with any of our recommended offshore sportsbooks.

Seattle Seahawks

The Seattle Seahawks rejoined the NFL in 2002, and have never looked back since. In 2013, they won their maiden Super Bowl by thrashing the Denver Broncos 43-8. The Seahawks also finished as runners-up in 2005 and 2014.

Seattle Kraken

The Seattle Kraken may have no Stanley Cups to their name, but ice hockey is hugely popular in Washington. The since-defunct Seattle Metropolitans dominated the NHL in the early 20th century, laying a tough foundation for the Kraken to follow. You can bet on them and any NHL game on a range of markets, including moneyline.

Seattle Sounders

Soccer has boomed in popularity in Washington state in recent years. This is in no small part to the success of the Seattle Sounders since they joined the MLS in 2009. The Sounders have already won the playoffs twice, in 2016 and 2019. Legendary US forward Clint Dempsey was instrumental in this. You can bet on the Sounders or any major division across the globe.

Seattle Mariners

The Seattle Mariners have struggled to achieve much success since joining MLB in 1977. They are the only active MLB franchise never to have appeared in the World Series. However, that does not stop fans at T-Mobile Park cheering on their team. You can wager on the Mariners or any MLB game on numerous bet types, including spreads.

Washington Sportsbook Payment Options

Providing as many payment options as possible is essential for any sportsbook. We understand that Washington state sports bettors are using various banking methods when wagering. Below is a breakdown of these options:

  • Cryptocurrency: Cryptocurrencies such as Bitcoin, Ethereum, and USDT are now widely accepted payment methods at WA state sports betting sites. They offer faster transaction times compared to traditional methods, enhanced privacy and security, and typically incur minimal or no fees.
  • Traditional Methods: Traditional banking methods, such as credit and debit cards, are typically available for deposits only and may incur fees. Bank transfers are commonly accepted for both deposits and withdrawals but often come with fees, higher minimum transaction amounts, and longer processing times.

Mobile Betting in Washington

If you value the convenience of mobile access, a well-optimized interface is essential. While state-regulated mobile betting is limited to on-site use at tribal casinos in the state, many offshore Washington sports betting sites offer mobile-friendly websites and apps accessible on Windows, iOS, and Android devices throughout the state. These sites or apps give you access to all the same markets you get at desktop sites, including live betting.

Retail Betting in Washington

Washington State is home to 29 federally recognized tribes, all eligible to apply for a sports betting license. Many have already secured licenses and launched retail sportsbooks at their casinos. The table below lists the casinos currently offering sports betting.

How We Review Betting Sites

Betting sites now offer much more than sports markets. Before recommending sportsbooks, we examine what they offer players, including everything from bonuses to odds. Our extensive criteria are used to rate betting sites, along with the considerations below.

  • Sports Coverage – Leading betting sites cover multiple sports. You would expect to find soccer, tennis, basketball, and golf. We credit bookmakers who accept bets on MMA, eSports, and other niche disciplines.
  • Betting Markets – Most sports offer pre-game, live, and outright markets. Parlay, prop, teaser, moneyline, and handicap bets are popular options.
  • Betting Odds – Betting sites must offer competitive odds. Whether in fractional, decimal, or another format, odds should give bettors a good mix of risk and reward. Many of our top-rated betting sites offer odds/price boosts on selected markets.
  • Live Streaming & Other Features – Live streaming is one of the most popular services. Watching events as they play out is entertaining and can boost your chances of picking a winner. Cash out, bet builder, and edit bet features are others we look out for.
  • Betting Specials – Promotions for new and existing customers help attract and keep bettors satisfied. Common offers include deposit bonuses, free bets, cashback, and odds boosts. We review the terms and conditions to determine where players have a realistic chance of profiting from bonuses.
  • Mobile Access – Players can access markets and features via their mobile browser or a native app. We consider usability, speed, and convenience when ranking betting sites in this area. Mobile-exclusive bonuses may even be available.

Final Thoughts

Although online domestic sports betting is technically legal in Washington, it’s essentially in-person only, as you must be physically present at a tribal casino to use a betting mobile app. This limitation removes much of the convenience typically associated with online gambling, which is why many residents turn to offshore betting sites like those featured in this guide.

If you want the flexibility of betting from anywhere, any of our top 10 platforms are great options. However, Betwhale stands out as our top WA sports betting site. It offers some of the best odds overall, a wide range of betting lines across multiple sports, and a variety of generous bonuses.
