The Washington State Gambling Commission has warned operators and players that prediction markets are not authorised in the state.

The warning was issued this week in response to rising interest in sports event contracts.

“While prediction markets are an unauthorized activity in Washington State, we acknowledge that the future of prediction markets, including those for sports, political events, etc., remains a subject of ongoing litigation both federally and in other states,” said the Commission.

“We will continue to monitor the ongoing cases as they progress through the court system and will provide updates once the courts provide further guidance.”

The Commission reminded consumers in the state that anyone interested in gambling on sports is able to do so legally at Tribal casinos authorized to conduct sports wagering under tribal-state gaming compacts.
