TLDR
- Wisconsin lawmakers passed Assembly Bill 601, sending a statewide sports betting bill to Gov. Tony Evers for his signature
- The bill uses a “hub-and-spoke” model based on Florida’s tribal gaming framework, with servers located on tribal land
- Wisconsin tribes would reportedly receive at least 60% of sports betting revenue, which may discourage major operators like DraftKings and FanDuel from entering
- Prediction markets from DraftKings, FanDuel, and Fanatics could offer an alternative path into Wisconsin for national operators
- Gov. Evers has six days, excluding Sundays, to sign, veto, or let the bill become law without his signature
Statewide sports betting in Wisconsin is now one signature away from becoming law. The state legislature has approved Assembly Bill 601 and sent it to Gov. Tony Evers.
The bill creates what is known as a “hub-and-spoke” sports betting model. This setup is based on how Florida and the Seminole Tribe agreed to allow statewide mobile wagering.
Under this model, anyone of legal age in Wisconsin could download an approved sports betting app and place wagers. The operator taking the bet would locate its servers on tribal land to keep the operation within the bounds of federally approved tribal gaming.
The Florida model survived a lengthy legal challenge before being fully implemented. Wisconsin lawmakers are hoping for a similar outcome.
How the Tribal Revenue Split Could Shape the Market
The big question now is whether major national sportsbooks will want to operate in the state. Under the Indian Gaming Regulatory Act of 1988, tribes entering gaming compacts with states must be the primary beneficiary of the operation.
Reports indicate Wisconsin tribes would receive at least 60% of sports betting revenue. That is a large share for operators used to keeping more of their earnings.
Casino gaming is far more profitable than sports betting. Sports betting margins have historically been smaller, though operators like DraftKings and FanDuel have improved margins through same-game parlay products.
In Florida, Seminole-owned Hard Rock Bet is the only approved statewide sports betting operator. Other companies could enter, but they would need to give the Seminole Nation a 40% share.
Given the revenue requirements in Wisconsin, some national sportsbooks may simply choose not to enter the market. The math may not work for companies used to operating under different terms.
Wisconsin tribes may instead turn to platform providers like Kambi to power their online sportsbooks. Those providers can offer similar types of wagers, but bettors would likely see fewer promotions and bonuses compared to what national brands typically offer.
Prediction Markets Could Offer a Workaround
There is another option that did not exist in years past. In 2026, several sportsbooks have launched prediction market platforms that can touch on sports.
DraftKings, Fanatics, and FanDuel have all unveiled prediction market products in recent months. Currently, DraftKings and FanDuel have kept sports markets out of Wisconsin on those platforms, but that could change.
FanDuel recently ran a free gas promotion in Tampa tied to March Madness through its prediction market platform. A similar push could happen in Milwaukee, Madison, or other Wisconsin cities.
Whether prediction markets can legally offer sports contracts is still being debated in courts across the country. The Ho-Chunk Nation has filed suit against Kalshi and Robinhood over this issue in Wisconsin.
Still, prediction markets may be the path some operators choose if the tribal revenue split proves too steep.
This scenario could also come into play if Evers vetoes the bill entirely. According to the Senate Clerk’s Office, the governor has six days, excluding Sundays, to act on the legislation. The bill becomes law if he signs it or if he takes no action during that window. A veto would require two-thirds majorities in both chambers to override.
