Washington Signs SB 6137: In-State College Betting Now Legal

industry

Washington Governor Bob Ferguson signed SB 6137 into law on March 31, 2026, allowing wagers on in-state college teams for the first time. Previously, betting on Washington-based universities like the University of Washington or Washington State was prohibited. 

This move marks a significant shift in Washington gambling and positions the state among a growing group of jurisdictions regulating college sports betting in the United States.

The new legislation reflects lawmakers' desire to bring college sports betting into a regulated environment. Tribal casinos will remain the primary platform for these wagers, ensuring oversight and compliance.

Meanwhile, online betting activity is expected to increase, offering more opportunities for US online sportsbooks to engage with Washington players.

Key Provisions of SB 6137

With the law officially in effect, several important provisions will shape legal betting on in-state colleges:

  • Bettors can now place wagers on game outcomes and general events for Washington-based colleges.
  • Betting continues to be limited to tribal casinos, keeping mobile sports betting restricted.
  • Player prop bets – wagers on individual athlete performance – remain prohibited.
  • Betting on coaching decisions such as substitutions or timeouts is not allowed.
  • Wagers tied to officiating decisions like fouls or penalties are also blocked.

The law was passed to address reality in sports betting. Legislators recognized that residents were already placing illegal wagers on local teams. By legalizing regulated betting, Washington can generate revenue, enforce compliance, and protect student-athletes.

Athlete Protection Measures and Ongoing Concerns

A core component of SB 6137 is the protection of student-athletes. The law imposes criminal penalties for anyone who threatens or harasses athletes, coaches, or officials. Additionally, offenders may face betting bans.

Despite these protections, concerns remain. Critics warn that expanding college sports betting could increase harassment of student-athletes and threaten the integrity of games.

At the national level, debates continue over whether college prop betting should be legalized. Advocates emphasizing revenue and regulation, while opponents cite ethical concerns. Washington's approach attempts to balance these competing interests.

Impact on Washington's Sports Betting Industry

SB 6137 is expected to stimulate the state's sports betting industry. Tribal casinos will see increased traffic, and legal betting on in-state college teams will likely draw new participants. 

While online sportsbooks remain limited, the law sets the stage for future expansion in digital platforms. Regulators and operators will need to ensure compliance while maintaining a fair betting environment.

Overall, Washington's legalization of in-state college sports betting positions the state as a leader in regulated gambling innovation, providing opportunities while protecting athletes and the integrity of collegiate sports.
