Incumbent Republican Zach Nunn faces Democrat Sarah Trone Garriott in Iowa's 3rd congressional district on November 3, 2026. The district's narrow 2024 Republican margin and status as a competitive swing seat contribute to trader positioning, with the Democratic Party holding a 77.5% implied probability compared to 22% for Republicans. Primaries concluded on June 2 with both candidates advancing unopposed. Limited recent polling shows a modest Republican edge, creating a noted divergence from current market consensus that may reflect national midterm dynamics or other factors. Scheduled events such as fall debates or additional surveys could influence assessments ahead of Election Day.
