Conservative Group Challenges Wisconsin’s Tribal-Only Online Sports Betting Law on Constitutional Grounds
TL;DR — WILL sued Wisconsin over its April-passed tribal-only online sports betting law, citing a 1993 constitutional amendment barring most gambling and equal protection violations based on tribal membership. The hub-and-spoke model mirrors Florida’s; compacts need federal approval. The suit seeks to block current and future expansions.
A conservative legal group has filed suit against Wisconsin, claiming the state’s new online sports betting law is unconstitutional. The Wisconsin Institute for Law and Liberty (WILL) brought the action in Waukesha County Circuit Court on behalf of the Brown County Taxpayers Association and Citizens Defending Liberty. The group announced the filing on August 5, 2026.
The legislation, passed in April, limits online sports betting to tribes under a hub-and-spoke model where wagers are considered placed where received. Any bet processed through a tribal server would count as placed in Indian Country. Tribes and state lawmakers have begun negotiating new compacts that require approval by the U.S. Department of the Interior before publication in the Federal Register.
WILL’s Constitutional and Equal Protection Arguments
WILL attorneys argue state lawmakers lack authority to expand gaming. They cite a 1993 constitutional amendment that bars the Legislature from “authoriz[ing] gambling in any form,” except for bingo and raffles licensed by the state, pari-mutuel on-track betting, and the state lottery. The complaint further claims the law violates equal protection by distributing benefits based on tribal membership.
WILL also seeks to block any future attempts to expand gaming in the state.
Commercial Operators’ Concerns and State Response
When Gov. Tony Evers signed the bill, Wisconsin became the second state after Florida to approve this tribal model. The state has 11 gaming tribes, while Florida has one, the Seminoles. In November 2021, in-person sports betting debuted in the state at the Oneida Casino, with other tribes joining under a “me-too” clause in existing compacts.
Commercial operators argued they would be shut out or required to pay tribes 60% of revenue in partnerships. It remains unclear whether tribes will partner with operators or launch white-label platforms. As reported by InGame, Britt Cudaback (@BrittCudaback) responded for the governor’s office: “Wisconsin Institute for Law & Liberty is a radical, right-wing entity that is actively working to undermine the sovereignty of the Tribal Nations in Wisconsin, and @GovEvers will fight that effort every step of the way.”
This filing creates immediate uncertainty for the compact negotiations now underway.

Wisconsin's tribal-exclusive sports betting model faces a constitutional challenge that could delay or derail the entire market.
We've been through the Florida compact saga and watched that model survive federal scrutiny. Now Wisconsin becomes the legal test case for tribal-exclusive mobile betting expansion beyond the Seminoles. If this challenge succeeds, it reshapes how tribes and states structure digital gaming compacts nationwide. Every operator watching Florida just got a second data point.
- WILL lawsuit cites 1993 state constitutional amendment barring most gambling expansion
- Commercial operators face potential 60% revenue share or exclusion from Wisconsin market

SCCG angle: SCCG works both sides of tribal partnerships — we've connected commercial operators to sovereign nations and advised tribes on operator selection across multiple jurisdictions. Clients considering Wisconsin or similar tribal-exclusive models need sharp legal read-throughs and partnership structures that survive constitutional scrutiny, which is where our decades of tribal and regulatory relationships prove essential.
