Sports betting could begin at tribal casinos in Washington state by next fall.

The Washington Indian Gaming Association says two tribes — the latest being the Suquamish Tribe — have now reached tentative agreements with the state gambling commission and it expects more agreements in the near future.

“Today’s announcement that the Suquamish Tribe is the second tribe to reach a tentative agreement on a compact with the state to allow sports wagering at their casino is another strong indication that our carefully regulated system of tribal gaming is working,” said Rebecca George, Executive Director of the Washington Indian Gaming Association (WIGA).
