This market will resolve according to the winner of the Republican Primary for Governor of Iowa, scheduled to take place on June 2, 2026. Resolution will be based on the overall winner of the primary, including any potential second round or run-off. If no 2026 Iowa 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 Iowa Republican Party; however, an overwhelming consensus of credible reporting may suffice.Zach Lahn secured the Republican nomination for Iowa governor in the June 2, 2026 primary after an open-seat contest triggered by Kim Reynolds declining to seek a third term. Lahn, a farmer and businessman emphasizing rural priorities, anti-abortion measures, and a “Make America Healthy Again” platform with RFK Jr. backing, edged U.S. Rep. Randy Feenstra—who held President Trump’s endorsement—by roughly one percentage point in a four-way field that also included Adam Steen, Brad Sherman, and Eddie Andrews. The narrow victory reflected strong grassroots organization and voter preference for Lahn’s Iowa-focused messaging over establishment and MAGA-aligned alternatives. Late certification disputes or recounts remain theoretically possible but face high procedural barriers given the reported results.
