Wisconsin has officially legalized online sports betting after Gov. Tony Evers signed Assembly Bill 601 into law. The new framework allows the state's 11 tribes to offer mobile sports betting statewide, but they must first update their gaming compacts with the state and receive federal approval before launching any sportsbook apps or websites.

Why it matters

The legalization of sports betting in Wisconsin marks the 33rd state to allow the activity, continuing the nationwide expansion of the industry. However, the tribal-focused structure of the new law means the typical national sportsbook brands may not be immediately available, as tribes must host the betting servers on their own lands and keep a majority of the revenue.

The details

Under the new law, each of Wisconsin's 11 tribes will have the ability to offer online sports betting statewide, but only after entering into updated gaming compacts with the state that include provisions for mobile wagering. These compacts must then be approved by the federal Bureau of Indian Affairs before any sportsbook apps or websites can go live. The process of negotiating and approving the compacts could take anywhere from a few months to several years, meaning Wisconsin bettors may have to wait until at least 2027 before they can place legal online wagers.

  • Gov. Tony Evers signed Assembly Bill 601 into law on April 9, 2026, legalizing online sports betting in Wisconsin.
  • Tribes must now negotiate updated gaming compacts with the state that include provisions for mobile sports betting, a process that could take several months to years.
  • The updated compacts must then be approved by the federal Bureau of Indian Affairs before any sportsbook operations can launch.

What’s next

The next steps for Wisconsin sports betting include the tribes negotiating updated gaming compacts with the state to include mobile wagering, followed by the Bureau of Indian Affairs approving those compacts. Only then can the tribes launch their own sportsbook apps and websites.

The takeaway

While Wisconsin has now joined the majority of U.S. states in legalizing online sports betting, the tribal-focused structure of the new law means bettors may have to wait until at least 2027 before they can place legal wagers, and the sportsbook options may be more limited compared to other states with commercial sports betting frameworks.
