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 holds a commanding lead in trader consensus at 72% implied probability for the Iowa Republican gubernatorial primary on June 2, driven by recent polls like a New York Times tracker showing him at 41% to Adam Steen's 9%, reflecting his strong name recognition, fundraising edge, and incumbency advantage from Congress despite base motivation concerns raised in April coverage. Challengers Zach Lahn (16%) benefits from grassroots endorsements including Iowa College Republicans, while former state administrator Adam Steen (10%) faces headwinds from a May 12 Democratic attack alleging job outsourcing to China; lower-tier candidates Brad Sherman and state Rep. Eddie Andrews trail amid limited momentum from April debates and May forums where Feenstra skipped appearances but polls held firm.
