This market will resolve according to the candidate who wins the nomination for the Democratic Party to contest the NH-01 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Democratic primary will take place on September 8, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Democrat sources, including https://democrats.org/. Any replacement of the nominee before election day will not change the resolution of the market.Trader consensus favors Stefany Shaheen at 59.5% implied probability to win the New Hampshire 1st Congressional District Democratic primary on September 8, propelled by her strong name recognition as daughter of Sen. Jeanne Shaheen and consistent polling leads in Saint Anselm and UNH surveys through late 2025 and early 2026. Maura Sullivan trails at 21% after outperforming Shaheen in fundraising for three straight quarters, including recent contributions from tech executives, and launching an "Unrig Washington" anti-corruption platform on March 24 amid voter concerns over political integrity. Heath Howard at 12.1% and Carleigh Beriont at 11% lag with limited visibility, though Beriont pushes old-school campaigning. The upcoming April 25 McIntyre-Shaheen Dinner headlined by Hillary Clinton could boost party turnout dynamics in this open-seat race.
