U.S. Rep. Tom Tiffany commands 90.5% implied probability as the Republican primary frontrunner for Wisconsin governor due to President Trump's late-January endorsement, which triggered Washington County Executive Josh Schoemann's immediate withdrawal and cleared much of the field, fostering GOP unity among activists and donors. As the incumbent congressman from the 7th District with deep northern Wisconsin roots, Tiffany leads early polls like the March Center Square survey at 40% and benefits from an open-seat race following Gov. Tony Evers' retirement. Trader consensus reflects his path-to-victory via incumbency advantages and party consolidation ahead of the August 11 primary. Challenges could arise from a late high-profile entry by figures like former Gov. Tommy Thompson or Rebecca Kleefisch, endorsement shifts, or unforeseen scandals.

If no 2026 Wisconsin Gubernatorial Republican Primary takes place, this market will resolve to “Other.”
The resolution source for this market will be the first official announcement of the results from the Wisconsin Republican Party; however, an overwhelming consensus of credible reporting may suffice.
