Wisconsin could soon authorize online sports betting after the state Senate passed Assembly Bill 601, sending the measure to Governor Tony Evers for potential signature. The legislation, approved in a 21-12 vote, would permit residents and visitors to place wagers via mobile or electronic devices, provided that the gaming servers processing the bets are located on tribal land.
The vote featured bipartisan support, with 12 Democrats and nine Republicans in favor. Opposition included nine Republicans and three Democrats. The measure follows the Assembly’s earlier approval in February through a voice vote, which advanced the bill without debate.
Senator Kristin Dassler-Alfheim, D-Appleton, one of the bill’s co-authors, said ahead of the vote, “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].”
Tribal Sovereignty And Regulatory Framework
AB 601 would operate under a “hub-and-spoke” system, with the hub being a server on tribal land and the spokes connecting users across the state. This model mirrors a recent federal case in Florida where the Seminole Nation was allowed to run a similar system.
Supporters emphasize that the measure reinforces tribal sovereignty while offering new revenue opportunities. Senate Minority Leader Dianne Hesselbein, D-Middleton, 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.”
Wisconsin has 11 federally recognized tribes, each holding exclusive rights to certain gambling operations under state gaming compacts. These compacts allocate a portion of revenue back to the state for economic development, local services, and tourism promotion. Amendments to these agreements, approved by the Bureau of Indian Affairs, have allowed the Oneida Nation, Forest County Potawatomi, and Ho-Chunk Nation to offer on-site sports betting.
Debate Over Problem Gambling And Commercial Opposition
Despite tribal and business support—including groups like the Milwaukee Brewers, the Tavern League of Wisconsin, and the Association of Wisconsin Tourism Attractions—thebill faces criticism. Opponents cite potential addictive behavior and financial harm. Senator Steve Nass, R-Whitewater, called the vote a “dirty deal,” while Senator André Jacque, R-New Franken, warned that removing physical barriers “creates natural limits” that the hub-and-spoke system eliminates.
Governor Evers has expressed cautious support contingent on broad tribal backing but recently indicated uncertainty over whether sufficient consensus exists. Anti-gambling advocates and national operators like DraftKings and FanDuel have also opposed the legislation, arguing the structure may not work for large-scale commercial providers.
Supporters point to unregulated prediction markets such as Kalshi and Polymarket as evidence that legal, regulated sports betting could help keep wagering within safe and monitored frameworks. A Marquette University Law School poll found that 64% of voters oppose legalization, while 34% support it.
If Evers signs AB 601, Wisconsin would join a growing list of states offering mobile sports betting while ensuring that tribal communities maintain control over online wagering and a majority share of generated revenue.
