A bill that would allow sports wagering in Wisconsin through the state’s tribes passed the Assembly on a unanimous voice vote Thursday, the final day the Assembly was scheduled to be in session.

It remains unclear if the Senate will take up the bill and send it to Gov. Tony Evers, who has voiced support for the plan.

The proposal would change the state’s definition of “bet” to allow the state’s tribes to offer mobile sports wagering if the bettor is in Wisconsin and the sportsbook servers are on tribal land, an amendment to current compacts allowing for casino gambling and sports wagering on tribal lands despite the state’s ban on betting.

The law would allow for a similar sports wagering model as Florida, where the state’s sportsbook operators have servers on federally recognized tribal lands while users can be in the state of Wisconsin.

The proposal cites the U.S. Supreme Court’s 2024 decision not to hear a challenge to the sports wagering pact between Florida and the Seminole tribe of the hub-and-spoke sports wagering model.

Wisconsin receives payments that are a portion of the net win from tribal casinos but does not separately report sports wagering payments.

In 2024, the state received more than $66 million in shared revenue payments with nearly $66 million in 2023 and nearly $57 million in 2022.

Sports wagering is legal in 39 states with 31 allowing mobile sports wagering.

The bill estimates it will bring hundreds of millions of illegal bets into legal sportsbooks in the state, stating the change “generates new revenue through tribal gaming compacts and reduces consumer risk from offshore operators.”

During committee discussion on the bill, Rep. Robert Wittke, R-Caledonia, pointed testimony from Sports Betting Alliance Counsel Damon Stewart, who said that a requirement that 60% of the gross revenue from mobile sports wagering under the Indian Gaming Regulatory Act would be too high of a cost for top national brands such as DraftKings, FanDuel, BetMGM, Fanatics and Bet365.

“I think our citizens in Wisconsin are better served by keeping this new platform within our current gambling structure,” Wittke said.
