A bipartisan bill to legalize online sports betting in Wisconsin is set for a vote in the state Senate this week, but the proposal faces pushback from some Republican lawmakers and national betting companies like DraftKings and FanDuel. The bill passed the Assembly last month, but support in the Republican-controlled Senate has been shaky. Opponents argue the legislation raises constitutional issues and would economically benefit the state's tribes at the expense of Wisconsin taxpayers.

Why it matters

The debate over legalizing online sports betting in Wisconsin highlights the ongoing tensions between state lawmakers, Native American tribes, and national gambling companies over the regulation and revenue sharing of this rapidly growing industry. The outcome of the Senate vote could have significant implications for the future of sports betting in the state.

The details

The proposed legislation would allow wagers to be placed on mobile or electronic devices by people located in Wisconsin, as long as the service or device processing the bet is on tribal lands. This would expand on recent compact amendments that have allowed some tribes to offer on-site sports betting. Supporters argue this would bring the state's sports betting industry out of a legal gray area, while opponents say it raises constitutional issues and would unfairly benefit tribes over national companies.

  • The bill passed the Wisconsin Assembly in February 2026.
  • The Wisconsin Senate is expected to vote on the bill during its session convening on March 17, 2026.

What they’re saying

“Absolutely, (Senate Republicans) are split on this. I think a lot of us are in favor of this, but right now sports betting is happening in the state of Wisconsin, but it's happening with these companies from out of state, out of country, and I think it makes sense our Native American tribes be able to benefit from this.”

— Dianne Hesselbein, Senate Minority Leader (WISN-TV)

“Make no mistake, AB 601 means the compacts will be opened far and wide to allow Gov. Evers to find ways to benefit the Tribes, potentially at the expense of Wisconsin taxpayers.”

— R.J. Pirlot, Lobbyist, Sports Betting Alliance (Email to Key Senate Republican Staff)

What’s next

The Wisconsin Senate is expected to vote on the sports betting bill during its session convening on March 17, 2026. If the bill passes the Senate, it would then go to Governor Tony Evers, who has indicated he may not sign it without broader support from the state's Native American tribes.

The takeaway

The debate over legalizing online sports betting in Wisconsin highlights the complex political and economic dynamics at play as states navigate the rapidly evolving landscape of the gambling industry. The outcome of the Senate vote could have significant implications for the future of sports betting in the state and the ongoing relationship between lawmakers, tribes, and national gambling companies.
