Washington College Sports Wagering: Reading the Oct. 15 Commission Vote

Washington's Gambling Commission is scheduled to decide on October 15, 2026 whether to forward two proposed tribal-state compact amendments on Washington college sports wagering to the governor. The amendments, negotiated with the Spokane Tribe of Indians and the Confederated Tribes of the Chehalis Reservation, would let those tribes' sportsbooks accept bets on in-state collegiate events, with specific integrity limits. The commission announced tentative agreements with both tribes on September 17.

The vote is one step in a multi-stage process that, in Washington, runs through the state commission, the Legislature's committees, tribal chairs, the governor and finally the U.S. Secretary of the Interior. Understanding that sequence is the best way to read what the October 15 vote does and does not accomplish.

What the amendments would change

According to the commission's announcement, the amendments adopt provisions from 2026 legislation authorizing sports wagering on college sports with limitations. Three terms are highlighted. In-state collegiate wagers become permissible bets. Wagers on the performance of an individual, on an in-game decision, or on an officiating decision in a collegiate sport or athletic event are prohibited. And individuals convicted of threats against officials, coaches or participants are barred from wagering.

Commission Chairperson Sarah Lawson described the revisions as adopting the legislative provisions with limitations. Spokane Tribal Chairman Greg Abrahamson thanked commission staff for acting promptly and noted that tribal patrons who follow Gonzaga and Washington State athletics would have a regulated place to bet.

The limits on individual-performance and in-game wagers track integrity concerns that regulators have raised about college sports, where athletes are amateurs and personal prop bets are viewed as more vulnerable to pressure. Washington's approach confines the permitted market to team-level outcomes.

The approval pathway, step by step

Under the process described in the announcement, formal notification of the proposed amendments goes to the governor, the Legislature and others. A joint public hearing of the Senate Business, Trade and Economic Development Committee and the House State Government and Tribal Relations Committee was set for October 1. The commission then votes on October 15 on whether to forward each amendment to the governor.

If forwarded, each amendment goes to the relevant tribal chair for consideration and signature, then to the governor. After both signatures, the tribe sends the amendment to the Secretary of the Interior for consideration, signature and publication in the Federal Register. Only then is the amendment in effect, and readers should note that the Secretary's role is governed by the Indian Gaming Regulatory Act. Our guide to reading a Federal Register compact notice explains the language those notices use, and our explainer on compact amendments covers the general mechanics.

A commission vote to forward an amendment is a procedural milestone. No new wager is lawful until the tribal chair, the governor and the Interior Department have each completed their steps.

Background on the two compacts

The Spokane Tribe's original compact was signed on February 16, 2007, and this would be its fifth amendment. The Chehalis compact dates to December 21, 1992, was restated on June 15, 2022, and this would be its eighth amendment. The long amendment histories illustrate how Washington compacts are updated incrementally rather than renegotiated from scratch, a pattern we examined in our report on the 2026 wave of Washington Class III amendments. Earlier coverage of this specific pair appears in our September report on the tentative agreements.

Why the sequence matters for tribes and regulators

For tribes, the layered approval is both a protection and a source of delay. Because each amendment must clear a state commission, tribal leadership, the governor and the federal government, a change adopted by statute in one legislative session may not reach a sportsbook floor until well afterward. For regulators, the sequence creates several points at which integrity terms can be examined and revised before they take effect. The commission's decision to write the prop-bet and in-game limits directly into the amendments, rather than leaving them to later rulemaking, places those restrictions inside the compact itself, where they bind the tribes' operations as a matter of agreement.

What to watch

The announcement does not specify a public comment deadline, though it invites comments by email to the commission. Observers will watch the October 15 vote, whether both amendments move forward together, and how quickly tribal chairs and the governor act afterward. Readers following the state more broadly can consult our Washington state hub.

The practical consequence for patrons is straightforward but not immediate. Until the full chain of signatures and federal publication is complete, college sports wagering at these tribes' sportsbooks is not authorized under the amended compacts. The October 15 vote is the next visible checkpoint, and the outcome will show whether the commission views the negotiated safeguards as sufficient to move the proposals to the governor's desk.
