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.U.S. Rep. Randy Feenstra leads trader consensus at 78.5% implied probability for the June 2 Iowa Republican gubernatorial primary, reflecting a mid-April Victory Enterprises poll of likely GOP primary voters showing him at 41%—a 32-point edge over challengers—with 31% undecided and single-digit support for Zach Lahn (8%), Adam Steen (9%), Brad Sherman (5%), and Eddie Andrews (5%). His advantages include strong fundraising, endorsements like Sen. Joni Ernst's April announcement praising his electability against Democrat Rob Sand, and name recognition from representing Iowa's 4th District. A April 28 Iowa PBS debate among Steen, Sherman, and Andrews criticized Feenstra's repeated debate absences as establishment avoidance, yet markets anticipate his consolidation of undecideds in the crowded field ahead of early voting.
