The open NH-01 seat, vacated by retiring incumbent Chris Pappas, features Democrat Stefany Shaheen against Republican Anthony DiLorenzo in a district with recent presidential margins under 6 points. Late September polling showed Shaheen ahead by roughly 4 points among likely voters, yet trader pricing reflects a near-even contest amid national attention on House control. High-profile October visits by Speaker Mike Johnson, who highlighted the district among top GOP targets, and House Minority Leader Hakeem Jeffries for Shaheen underscore its swing status and potential to shift outcomes based on turnout and late messaging on economic issues. These factors sustain tight implied probabilities across candidate and margin buckets, with limited separation until final returns clarify voter response.
