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.Stefany Shaheen maintains a strong lead in the New Hampshire 1st District Democratic primary, scheduled for September 8, 2026, driven by name recognition as the daughter of U.S. Senator Jeanne Shaheen, prior service on the Portsmouth City Council, and consistent polling advantages in recent surveys such as the Saint Anselm College poll. Maura Sullivan, a former Marine captain, vice chair of the New Hampshire Democratic Party, and 2018 candidate for the seat, trails but has narrowed the margin through substantial fundraising and targeted campaigning focused on lowering costs and building statewide support. Heath Howard, a sitting state representative, and Carleigh Beriont, a Hampton selectwoman, remain distant contenders with limited polling visibility and smaller organizational footprints. Trader positioning reflects Shaheen’s structural edges in endorsements and local ties while acknowledging Sullivan’s resource base and potential for late momentum in the open-seat contest.
