The only legal sports‑betting app in Washington State in 2026 is the state‑approved Washington Sports Betting platform, operated under the authority of the Washington State Gambling Commission and partnered with BetMGM. All other mobile sportsbooks are prohibited until they receive a license from the Commission, making Washington Sports Betting the exclusive online venue for wagering on professional and collegiate sports within the state.
Legal Framework in Washington
Washington’s gambling laws were updated in 2025 when the legislature passed Senate Bill 4825, authorizing regulated online sports betting. The bill created a single‑license model: the Gambling Commission awards one master license, which it can delegate to a commercial operator. BetMGM won the contract after a competitive bidding process, and the resulting app—Washington Sports Betting—became the only platform authorized to accept wagers from Washington residents.
The Commission maintains strict oversight, requiring real‑time reporting of bet totals, player age verification, and adherence to responsible‑gaming protocols. Violations can result in immediate suspension of the license and heavy fines, reinforcing the exclusivity of the sanctioned app.
Features of Washington Sports Betting
- State‑wide Availability: The app works on iOS and Android devices throughout all 39 counties.
- Secure Identity Checks: Users must provide a Washington driver’s license or state ID and undergo biometric verification.
- Comprehensive Markets: From NFL and NBA to NCAA football and college basketball, the app offers point spreads, money lines, totals, and prop bets.
- Responsible‑Gaming Tools: Limits on deposit amounts, self‑exclusion options, and real‑time alerts help users stay in control.
- Tax Transparency: A 5 percent state tax is automatically deducted from winnings, and users receive an annual statement for tax filing.
Why Other Apps Are Not Legal
Unlicensed operators such as DraftKings, FanDuel, and Bet365 may appear in app stores, but Washington law classifies their services as illegal gambling. The Commission actively blocks IP addresses, and payment processors are required to refuse transactions linked to unauthorized betting. Users caught wagering on prohibited platforms risk civil penalties and, in extreme cases, criminal charges for illegal gambling activity.
