Iowa Governor Race 2026 — Odds
Kim Reynolds's retirement created Iowa's first open governorship since 2006, pitting Republican Zach Lahn against State Auditor Rob Sand, the only Democrat holding statewide office and a record-breaking fundraiser. Sand's cross-party brand keeps markets closer than Iowa's red lean would suggest, with the GOP priced in the low 60s. This is one of the few governor races where forecasters and traders openly disagree.
