Wisconsin Governor Tony Evers is set to decide this week on Assembly Bill 601 (AB 601), legislation that would legalize statewide online sports betting under a tribal-controlled framework. The bill, which has already cleared both chambers of the state legislature, would allow mobile wagering while requiring bets to be processed through servers located on tribal lands.
Momentum behind AB 601 has been reinforced by significant tribal support, with eight of Wisconsin’s 11 federally recognized tribes formally expressing approval in a joint letter. The coalition emphasized that any expansion of online sports betting should remain rooted in tribal control, aligning with existing gaming compacts and preserving sovereignty.
Tribal leaders argued that the proposal offers a path to modernize wagering in the state while ensuring tribes continue to play a central role in both operation and oversight. Although a small number of tribes have not publicly endorsed the measure, the broad backing highlights a notable level of consensus that can influence Gov. Evers’ upcoming decision.
Gov. Evers has stated that his decision will depend in part on further discussions with tribal nations that have not endorsed AB 601. He wants to review the bill in detail while consulting with stakeholders to better understand any remaining concerns before making a final call.
Under Wisconsin’s legislative process, Evers has three options: he can sign the measure into law, reject it and return it to lawmakers with objections, or allow it to take effect without his signature. Should he veto the bill, legislators could still enact it if both chambers secure a two-thirds majority to override.
Lawmakers have already advanced AB 601 through the legislature, with the Wisconsin Senate approving the measure in March and the Assembly passing it earlier in the session. The proposal outlines a “hub-and-spoke” model, where online wagers are placed remotely but routed through servers located on tribal land. This is a similar framework used by the Seminole Tribe in Florida.
If enacted, the bill would permit online sports betting only through tribes that hold approved gaming compacts with the federal government. To participate, tribes would need to amend those agreements to include mobile wagering, either by operating their own platforms or partnering with established sportsbook operators.
If AB 601 is approved, attention will quickly turn to which major operators might try to gain entry into Wisconsin through tribal partnerships.
This raises questions about whether leading platforms like FanDuel and DraftKings would strike agreements to gain access to the market.
A comparable setup in Florida offers some insight into how the market could evolve. There, the Seminole Tribe maintains exclusive control, with Hard Rock Bet as the primary online platform.
Wisconsin could see a broader range of operators if multiple tribes choose to partner with different sportsbook brands, but it’s also possible the market remains more limited, as in Florida.
