U.S. Rep. Tom Tiffany dominates trader consensus at 88.5% implied probability for the Wisconsin Republican gubernatorial primary on August 11, bolstered by President Trump's January endorsement that prompted rivals like Washington County Executive Josh Schoemann to exit, consolidating grassroots conservative backing alongside major donors such as the Uihleins and Diane Hendricks. Former Gov. Tommy Thompson's March signals of a potential challenge—despite his age of 84—have elevated his odds to 6.7%, reflecting his enduring name recognition amid polls showing uneven GOP voter enthusiasm for Tiffany. Lower probabilities for Eric Hovde, Rebecca Kleefisch, Sean Duffy, and others underscore the cleared field, with party unity favoring the incumbent congressman ahead of the summer contest.

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.
