Trader consensus on Polymarket heavily favors U.S. Rep. Randy Feenstra at 52% implied probability to win the Iowa Republican gubernatorial primary, bolstered by his incumbency in Iowa's 4th Congressional District, strong early fundraising exceeding $1 million, and endorsement from term-limited Gov. Kim Reynolds last week. Challenger Adam Steen holds 22.5% on grassroots momentum and a recent Des Moines Register poll showing him at 25% among likely primary voters, up from 15% in October amid aggressive barnstorming. Zach Lahn's 13.1% reflects niche evangelical support following viral social media clips from town halls, while lower tiers like Brad Sherman and Eddie Andrews trail on limited visibility. Recent polls and Reynolds' backing have widened Feenstra's lead, with the first debate slated for March potentially shifting dynamics.

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.
