The Wisconsin State Assembly has approved a plan to legalize statewide mobile sports wagering, passing Assembly Bill 601 on Feb. 19.
According to reports from the Milwaukee Journal Sentinel, the bill now moves to the state Senate, where a tight legislative calendar and internal Republican skepticism pose significant hurdles before the session concludes in mid-March.
Current status: The “hub-and-spoke” model
The proposal establishes a “hub-and-spoke” model, which legally anchors online sports betting to physical servers on tribal land. Under this framework, a resident could place a wager from a smartphone anywhere in Wisconsin, but the transaction is legally treated as occurring on tribal property.
This model is designed to navigate Wisconsin’s constitutional limits on gambling by keeping the activity within the existing tribal framework rather than opening the market to outside commercial operators.
While the bill avoids a new state tax, it relies on tribal-state compacts to determine revenue sharing. Estimates from the Legislative Reference Bureau suggest that legalizing mobile betting could increase the state’s annual gaming revenue by $6 million to $12 million. If the bill passes the Senate, Gov. Tony Evers must negotiate individual compact amendments with the state’s 11 federally recognized tribes, which then require final approval from the US Department of the Interior.
Impact: Tribal revenue and consumer protection
The bill received a significant boost during the State of the Tribes address earlier this month. Nicole Boyd, chairperson of the Red Cliff Band of Lake Superior Chippewa, urged lawmakers to view the bill as a vital economic tool for tribal self-sufficiency.
Speaking for the Great Lakes Inter-Tribal Council, Boyd told Wisconsin Public Radio that the framework would bring “hundreds of millions of dollars” in currently unregulated bets under state oversight while funding essential tribal services like health care and public safety.
Opposition remains centered on social and constitutional concerns. Some Republican legislators, including Senate President Chris Kapenga, have voiced opposition citing the risks of gambling addiction and the creation of a tribal monopoly. Furthermore, the Sports Betting Alliance, which represents national brands like FanDuel and DraftKings, has criticized the bill’s financial structure, arguing that the tribal-focused model makes it economically unfeasible for major national sportsbooks to operate in the state.
The March deadline: Will the Senate act?
The bill’s future now rests with the Senate, where timing is the primary obstacle. Senate Majority Leader Devin LeMahieu recently noted that while the policy “makes sense,” he is uncertain if there are enough votes to move it across the finish line.
The Senate has a narrow window in mid-March to act. If the bill is not passed in its current form by the end of that period, it will expire with the end of the session. Because any Senate amendments would require the bill to return to the Assembly—which has already finished its scheduled work—the Senate likely must pass the bill exactly as written for it to reach the governor’s desk this year.
