Is Sports Betting Legal in Washington? Only Inside Tribal Casinos

✓ Last verified: 2026-08-13

Sports betting is legal in Washington, but only inside a tribal casino, and only while you are physically standing there. There is no statewide betting app, and none is even authorized. Betting online from your couch is a class C felony under RCW 9.46.240, and the state’s own Gambling Commission has published, in its own words, that the person placing the bet violates the law along with the site taking it.

One thing did change in June 2026. SB 6137 took effect on June 11, 2026 and removed Washington’s ban on wagering on its own college teams, so the Huskies, Cougars and Gonzaga are legal at team level as a matter of state law. But you still cannot place that bet, because every tribe’s compact appendix carries the old ban as separate contract text and none has been amended yet.

The law that makes Washington different

Most states that do not have betting apps simply have not legalized them. Washington is not in that category. It has a criminal statute aimed squarely at online gambling, and it is the reason this state has the harshest reputation in the country.

RCW 9.46.240 makes it a class C felony to “knowingly transmit or receive gambling information” by internet or similar means. Read the verbs: transmit or receive. There is no exception in that section for the person placing a bet. The only carve-out covers gambling that a tribal compact authorizes, which is exactly why betting inside a tribal casino is fine and betting from your living room is not.

Two details matter, and most write-ups get both wrong.

First, this became a felony in 2006, not decades earlier. Until June 7, 2006 it was a gross misdemeanor. A bill that year inserted the words “the internet” into the statute and raised the grade at the same time. Washington made online gambling a felony deliberately, and recently.

Second, the reach to the bettor runs through a definition rather than the face of the statute. The section says “whoever,” and “gambling information” is defined elsewhere (RCW 9.46.0245) to include any wager made in the course of professional gambling, with a presumption that wagers and odds are meant for it. An offshore sportsbook is engaged in professional gambling, so your wager placed with one is caught. Note that the word doing the work is a presumption, and that the statute requires you to act knowingly.

What the state actually says, and what it does not

The Gambling Commission has said in two separate published documents that the bettor is a violator. Its online gambling FAQ states that when someone places a bet online “both the party making the wager and accepting the wager have violated the law,” and that “you are violating Washington State law if you knowingly gamble through an online gambling website.” A dated September 19, 2025 notice about the offshore book Bovada puts it in statutory terms: the operator “and participants (who may not even know they are wagering illegally) are in violation of RCW 9.46.240, which is a class C felony.”

Now the honest other half, because a page that only tells you the scary number is not being straight with you.

The realistic sentencing exposure is much smaller than the headline. A class C felony carries a statutory maximum of five years and a $10,000 fine. But RCW 9.46.240 is an unranked felony: it has no entry in the state’s seriousness-level table, so for an unranked offense the court imposes a sentence that may include not more than one year of confinement. The presumptive range for a first offense is zero to twelve months, not five years. Both numbers are true, and quoting only the first one is misleading.

And no prosecution of an individual Washington bettor for placing a bet is on the public record. The one time a player took the statute on, it survived. In Rousso v. State (No. 83040-1, decided September 23, 2010), a Washington attorney who played poker online sought a declaratory judgment that the ban was unconstitutional. The state Supreme Court upheld it unanimously. He was a plaintiff, never a defendant, and was never charged. So a player had standing to challenge the law as it applied to playing, and lost.

What that adds up to: the exposure is real and the state says so in writing, the sentencing reality is far below the headline, and enforcement in practice has visibly targeted the offshore operators rather than their customers. What you should not take from this page is a promise that the risk is zero, because the Commission has never said that.

What you can actually do today

Sports betting arrived in Washington through a 2020 law that did not open a commercial market at all. It authorized the state to negotiate compact amendments with tribes, and betting went live in September 2021. Cardrooms and racetracks were left out on purpose.

Most of the state’s tribal casinos now take sports bets. Counting the Gambling Commission’s own casino-location list, 24 of the 29 tribal casinos are flagged for sports wagering. The Commission publishes no total of its own, so that is our count of its list as of July 31, 2026.

Phone betting exists, but the fence is tight and it is a state mandate rather than a tribal choice. The rule is that a gaming operation “must use a geofence to ensure that patrons can only place mobile sports wagers while they are physically on the premises.” So the phone works in the building, not on the reservation generally, which makes Washington’s fence tighter than Wisconsin’s, where one tribe’s app works across its whole reservation.

Every Washington app we examined also requires an in-person step to get started, which is the same shape as Nevada’s activation rule, arrived at from a completely different direction:

This is the state that quietly falsifies a common assumption: the big national brands do operate outside the open-market states. DraftKings, Caesars and FanDuel all run Washington books. They just do it inside somebody’s casino. If you are trying to work out which app follows you across state lines, our guide to which betting apps are legal where you live sorts every state by market model.

The age varies by tribe. The compact floor is 18, and most books set 21, in large part because compacts require 21 wherever alcohol is served in the gaming area. But 12 Tribes Colville Casinos takes sports wagers at 18 at its Lake Chelan, Omak and Coulee Dam books. So neither “Washington is 21+” nor “Washington is 18+” is true, and the state does not belong on the list of 18+ jurisdictions.

The college change that has not landed yet

Until this summer, Washington barred bets on its own schools. SB 6137, signed by Governor Bob Ferguson on March 30, 2026 and effective June 11, 2026, struck that exclusion. At statute level, team-level bets on Washington colleges are now permitted.

You still cannot place one. Each tribe’s compact appendix carries the identical old exclusion as its own standalone contract text, and a statute does not rewrite a contract. The compacts have to be amended one by one, and that process runs through a legislative hearing, a Gambling Commission vote, the Governor’s signature, federal review, and finally publication in the Federal Register, which is the moment an amendment takes legal effect. As of July 31, 2026 none has completed that path. The only two Washington compact amendments published in the Federal Register this year, for the Port Gamble S’Klallam and Upper Skagit tribes, do not touch the college rule. So the accurate sentence is that Washington changed the law but the bet is not on the board.

Three restrictions survived the change and are worth knowing:

College props generally are allowed, and the state’s own authorized wagering menu carries dozens of NCAA basketball and football player-prop markets. Washington is the fifth state in a row where we found the “this state bans college betting” assumption to be wrong, after Nebraska, North Carolina, Nevada and Wisconsin.

Why only tribes, and the lawsuit that tested it

Washington’s decision to hand sports betting exclusively to tribes drew the obvious challenge. A cardroom operator sued, arguing the arrangement was unlawful and discriminatory.

The case ended without a ruling on whether the exclusivity was lawful. A tribe intervened, asserted sovereign immunity as a necessary party that could not be joined, and the case was dismissed on that basis rather than on the merits. The distinction matters: Washington’s tribal-only market was never blessed by a court, it was insulated from review. Anyone challenging it next faces the same procedural wall.

That structure also explains a money fact. There is no state tax on Washington sports betting, because federal law bars a state from taxing tribal gaming. And there is no published handle or revenue figure either. The Commission’s own annual gambling activity report does not break out sports at all. Washington is now the fourth regulator in a row we have checked whose published numbers omit the total everybody quotes, after Nebraska, Tennessee and Nevada.

Prediction markets: Washington sued, and on July 20 it won

The obvious tension: in the state with the country’s toughest online gambling statute, prediction markets stream sports contracts to anyone with a phone.

Washington fought them harder than most, and it has now won the first round. The Gambling Commission issued guidance in December 2025, Attorney General Nick Brown sued KalshiEX in King County Superior Court on March 27, 2026, and after argument on July 10 Judge John F. McHale granted the state a preliminary injunction on July 20, 2026 (order, State of Washington v. KalshiEX, LLC, No. 26-2-10264-3 SEA).

What the court held. The Commodity Exchange Act does not preempt Washington gambling law: the “exclusive jurisdiction” granted to the CFTC was written to divide work among federal agencies, the judge reasoned, not to displace the states, and it carries savings clauses for state regulators and state courts. On that footing the state is likely to succeed under three statutes, not one: the Gambling Act, the Consumer Protection Act, and the Recovery of Money Lost at Gambling Act.

The consumer-protection half is the part no other state has, and it is worth quoting. The court concluded that Kalshi’s “provision, marketing, and advertising of illegal gambling activities constitute unfair and/or deceptive acts or practices.” It also found that Kalshi “has willfully ignored a Washington State Gambling Commission notice stating that offering event-based contracts is not authorized in Washington state,” which is the same December 2025 guidance described above. No security or bond was required of the state.

The operative order now exists, and Washington has joined the blocked column. The July 20 order imposed exactly one obligation: Kalshi had to preserve records relating to Washington consumers, including logs, geolocation determinations, and marketing data. It carried no geofence, no blocking deadline and no daily penalty, because the judge deliberately left those terms for later. He said he would have issued full directives that day, but Kalshi’s counsel asked to confer with the state first, and he allowed it “with the hope that Kalshi, through experience with other States, may provide insight into effective ways to protect Washingtonians.” The parties filed terms by noon on August 3, 2026, and the court then entered the operative order.

That order sets a two-stage geofence. By August 10, 2026 Kalshi was to implement IP-address and residency-based geofencing, and by August 26, 2026 it must have in place a multi-source geofencing solution supplied through GeoComply, described in the order as designed to prevent anyone located within the geographic boundaries of Washington from purchasing any event contract. We have not read the order ourselves; those terms are quoted from the King County Superior Court docket as reported, and no compliance finding had been published as of August 13, 2026.

So the answer changed in August. Washington now sits alongside Michigan and Nevada as a state where a court has ordered the platform to shut residents out, rather than one that has merely declared the product unlawful. The date that still matters is August 26, 2026, when the full geofence is due.

The win also drew a second platform to court, this time as a plaintiff. Two days after the Kalshi injunction, on July 22, 2026, North American Derivatives Exchange, which runs Crypto.com’s OG prediction market, sued Attorney General Nick Brown and the Gambling Commission’s members in federal court in the Western District of Washington (No. 2:26-cv-02579), asking a judge to declare that the Commodity Exchange Act preempts Washington’s gambling laws before any enforcement reaches it. It is the second platform to sue Washington preemptively, after Robinhood, and it points to the same federal framework the CFTC invoked when it ordered Kalshi to honor Michigan trades on July 14. Nothing has been decided in the case: no order has issued, and OG is the one asking.

Three points of precision, because this is where our other pages have gone wrong before. Washington is not one of the nine states the federal government has sued. This was a state trial court, so it does not create the federal appeals-court split that still does not exist. And the state separately agreed, in a federal court order, not to enforce RCW 9.46.240 against Robinhood while the Ninth Circuit cases are pending. Separately, Kalshi’s appeal of the earlier decision sending this case back to state court is frozen: on July 16, 2026 the Ninth Circuit paused that briefing until 30 days after it decides the three Nevada prediction-market appeals. Earlier, refusing Kalshi a stay, that court said “principles of federalism and comity” favored “allowing Washington an opportunity to enforce its laws in state court.”

Washington sits in the Ninth Circuit, which is holding Kalshi’s appeal of its Nevada loss, argued in April 2026 and undecided. A merits ruling there would land directly on Washington. Nationally, no federal appeals court has yet ruled on the merits of whether federal commodities law overrides state gambling law.

What would have to change

Wisconsin needs one thing to get statewide apps: a compact amendment published in the Federal Register. Washington needs two, and it is strictly the harder case.

  1. The Legislature has to amend RCW 9.46.0368 to remove the requirement that you be physically present. The next window opens when the Legislature convenes on January 11, 2027. In 2026 lawmakers went the other way and re-enacted the physical-presence language.
  2. A compact amendment authorizing off-property mobile has to publish in the Federal Register.

Nobody credible has forecast when, or whether, either will happen. That is the honest answer, and we would rather give it than invent a date.

Frequently asked questions

Can I use DraftKings or FanDuel in Washington? Only inside the casinos where they operate. DraftKings runs the books at Tulalip’s two casinos with an app that works on the property, and FanDuel runs the book at Suquamish Clearwater. Neither works from home.

Is it actually illegal for me to bet online here? Yes, and Washington is unusual in saying so plainly. Placing a bet with an offshore site is covered by a class C felony statute, and the Gambling Commission has published that the bettor violates the law too. The realistic sentencing range for a first offense is zero to twelve months rather than the five-year maximum, and no prosecution of an individual bettor is on the public record, but the exposure is not theoretical.

Can I bet on the Huskies or the Cougars? Not yet. The law changed on June 11, 2026 to allow it, but the tribal compacts still bar it and have to be amended first.

How old do I have to be? 21 at most Washington sportsbooks. Some, including the 12 Tribes Colville casinos, take sports wagers at 18.

Will Washington get betting apps? Not soon, and not through one step. It would take both a change to state law, which cannot happen before the Legislature convenes in January 2027, and a federally published compact amendment.
