**Stefany Shaheen holds a strong lead in the NH-01 general election market following her narrow Democratic primary victory on September 8, 2026.** The open seat, vacated by Rep. Chris Pappas’s Senate bid, is rated Lean or Likely Democratic by forecasters including Cook Political Report, Inside Elections, and Sabato’s Crystal Ball, consistent with the district’s recent performance where Kamala Harris carried it by roughly two points in 2024. Shaheen, a former Portsmouth city councilor and health care entrepreneur with high name recognition as the daughter of retiring Sen. Jeanne Shaheen, consolidated support after a competitive primary against Maura Sullivan and others. Anthony DiLorenzo, a businessman who secured the Republican nomination with former President Trump’s endorsement, faces structural headwinds in a district that has not elected a Republican to the House in over a decade. Higher Democratic primary turnout and the seat’s partisan baseline underpin trader pricing ahead of the November 3 general election.
