Wisconsin Moves Toward Tribal Online Sports Betting

Wisconsin lawmakers are entering the 2026 legislative session with renewed momentum behind a proposal to legalize online sports betting under a tribal-exclusive framework, setting the stage for a likely vote in the State Assembly early this year.

Assembly Speaker Robin Vos said last week that lawmakers are finalizing a bipartisan bill and expect it to receive an Assembly vote once the Legislature convenes on Jan. 13. While details are still being refined, Vos indicated that negotiations are focused on addressing concerns raised by both supporters and skeptics of online wagering.

“It’s already happening,” Vos told the *Milwaukee Journal Sentinel*, referring to unregulated betting activity. “So, I guess if we already have it, I would rather say that if we’re going to have it in Wisconsin, it can be regulated in a way that’s more transparent.” An online sports betting bill was pulled from the Assembly calendar just before a scheduled vote in November after some lawmakers raised unresolved questions about its structure and potential consequences. Assembly Majority Leader Tyler August said at the time that additional deliberation was needed.

 

• Wisconsin lawmakers are finalizing a bipartisan, tribal-exclusive online sports betting bill that is expected to receive a vote in the Assembly during the 2026 legislative session.

• The proposal would allow statewide mobile betting processed on tribal land, requiring renegotiation of gaming compacts and federal approval, while preserving tribal control of sports wagering.

• Lawmakers are working to address problem gambling, microbetting, and market exclusivity concerns as they weigh regulation against unregulated and offshore betting.

 

What’s Been Happening?

“There’s really no rush on this,” August said in November. “I had a conversation with a couple of members over the weekend that brought up some points that I hadn’t considered yet, so we’re going to work through those and I expect that we will be voting on it early next year.”

Governor Tony Evers has signaled that he would sign sports betting legislation provided it has the backing of Wisconsin’s tribes. The state’s 11 federally recognized tribes already operate in-person sportsbooks at casinos under a 2021 amendment to their gaming compacts, and the proposed legislation would extend that authority to online wagering.

The bill under consideration reflects the legal and political realities of gaming in Wisconsin, where tribal exclusivity is embedded in state-tribal compacts. Under last year’s proposed language, co-authored by August, online bets would be permitted on mobile or electronic devices anywhere in the state, as long as the wager is processed on servers located on tribal land. The structure mirrors the “hub-and-spoke” model used in Florida, where the Seminole Tribe controls statewide mobile betting.

All Wisconsin tribes would be eligible to participate and could partner with commercial sportsbook operators. However, implementing the system would require renegotiation of existing gaming compacts and approval from the federal Bureau of Indian Affairs.

The framework has drawn criticism from some lawmakers and commercial operators who oppose limiting online sports betting to tribal entities. During a November hearing, the Sports Betting Alliance, which represents major national sportsbook companies, urged lawmakers to reconsider the tribal-exclusive approach.

Vos acknowledged the discomfort but suggested alternatives are limited. “That’s the way it is. We can’t fix that,” he said. “That’s why some people just have to accept where we are or at least talk about it.”

Beyond market structure, lawmakers are grappling with broader policy concerns, including the rise of microbetting, the risk of increased problem gambling, and the presence of offshore sportsbooks and prediction markets. Vos pointed to these unregulated options as a reason to favor a regulated system, noting that the Ho-Chunk Nation has filed a lawsuit against Kalshi, alleging the company is offering illegal sports betting through prediction markets.

 

If we’re going to have online sports betting in Wisconsin, it should be regulated in a way that’s transparent and accountable.

 

The New Policy

The Wisconsin Policy Forum has also flagged these issues, releasing a report last year outlining regulatory, fiscal and social considerations lawmakers must weigh before expanding sports betting.

Despite the concerns, the proposal has attracted support from tribal leaders and Wisconsin’s professional sports teams. Dominic Ortiz, CEO of Potawatomi Casinos & Hotels, said on “The New Normal” podcast in November that the legislation would “create a fair playing field and unite the tribes.”

As lawmakers work toward a final bill, the outcome in Wisconsin could serve as a test case for other states seeking to balance online sports betting expansion with tribal gaming rights. Whether the carefully negotiated framework can secure enough legislative support remains an open question, but Assembly leaders appear increasingly confident that a vote — and a decision — is approaching.
