U.S. Rep. Tom Tiffany dominates trader consensus at 86% implied probability to win the Republican primary for Wisconsin governor, driven by his incumbency advantage, prior state Senate service, and solid northern Wisconsin base that bolsters his path to statewide support. Former Gov. Tommy Thompson trails at 9%, leveraging historical name recognition despite his age (82) and extended retirement raising viability questions among bettors. No formal candidate announcements, endorsements, or primary polling have surfaced in the past 30 days, sustaining early market positioning reflective of skin-in-the-game assessments ahead of the August 2026 primary. Other contenders like Rebecca Kleefisch and Sean Duffy linger below 1% amid past electoral setbacks and unproven gubernatorial bids.

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.
