U.S. Rep. Tom Tiffany commands 90.5% implied probability in the Wisconsin Republican gubernatorial primary market, driven by former Gov. Tommy Thompson's endorsement five days ago, which quelled speculation about Thompson's own candidacy and solidified Tiffany's frontrunner status among traders. This builds on President Trump's January endorsement and March Marquette polling showing Tiffany at 40% to challenger Andy Manske's 6%, with 54% undecided in a thin GOP field featuring few declared rivals. High trader consensus reflects Tiffany's incumbency advantage, fundraising momentum, and rural Wisconsin base, though late entries by figures like Rebecca Kleefisch or Tim Michels, scandals, or polling shifts could challenge his path to the August 11 primary victory.

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.
