Wisconsin Senate Advances Mobile Sports Betting Bill
Wisconsin lawmakers have taken a further step toward introducing mobile sports wagering, with the state Senate approving Assembly Bill 601 in a 21-12 vote. The proposal now moves to Governor Tony Evers, who has yet to confirm whether he will sign it into law.
The legislation received backing from both major parties. Twelve Democrats and nine Republicans supported the measure, while nine Republicans and three Democrats voted against it. The Assembly had already cleared the bill earlier in February through a voice vote, allowing it to progress to the Senate stage.
If enacted, the proposal would allow both residents and visitors to place bets across the state using mobile devices. All wagers, however, would need to be processed through servers located on tribal land, forming the basis of the regulatory model.
Tribal-Centered Model Defines Betting Structure
The proposed system relies on what lawmakers describe as a “hub-and-spoke” structure. Under this setup, a central server located on tribal territory would function as the operational hub, while bettors across Wisconsin would connect remotely through their devices.
Supporters of the bill view this framework as consistent with established legal interpretations, including a recent federal case involving the Seminole Nation in Florida that permitted a similar arrangement. The approach is also designed to align with Wisconsin’s long-standing agreements with tribal governments.
The state is home to 11 federally recognized tribes, each holding exclusive rights to certain forms of gambling under existing compacts. These agreements ensure that a portion of gaming revenue contributes to public initiatives such as tourism, economic development, and local services.
Senator Kristin Dassler-Alfheim, one of the bill’s co-authors, addressed the Senate before the vote, stating, “If we’re going to have online gambling – which we are. It already exists on the edges, behind closed doors. It’s already there. And it’s already being abused by some and that’s not going to change. I would rather us put as many parameters around it as we can to take care of our consumers and keep the revenues [in Wisconsin].”
Senate Minority Leader Dianne Hesselbein also highlighted the broader implications for tribal governance. She said, “I really think this moment is about collective assertion of tribal sovereignty and the preservation of exclusivity that tribes have fought decades to establish.”
Several tribes have already expanded into sports betting through amendments approved by the Bureau of Indian Affairs. The Oneida Nation, Forest County Potawatomi, and Ho-Chunk Nation currently offer on-site wagering at their respective properties.
Debate Continues Over Market Expansion
Despite gaining legislative approval, the proposal has faced resistance from multiple groups and policymakers. Senator Steve Nass described the bill as a “dirty deal,” while Senator André Jacque raised concerns about the removal of physical limitations that could otherwise restrict betting behaviour.
Criticism has also come from anti-gambling advocates, along with major industry operators such as DraftKings and FanDuel, both of which have questioned aspects of the proposed structure.
Public opinion remains divided on the issue. A survey conducted by Marquette University Law School found that 64 percent of respondents oppose the legalization of online sports betting, while 34 percent support it.
At the same time, the bill has drawn backing from tribal organizations and business groups, including the Milwaukee Brewers, the Tavern League of Wisconsin, and the Association of Wisconsin Tourism Attractions.
If signed into law, the measure would position Wisconsin among states that allow mobile sports wagering, while maintaining a system that places operational control within tribal frameworks. The final decision now rests with the governor, as the state weighs expansion against regulatory and social considerations.
