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 leads trader consensus at 60% implied probability in the NH-01 Democratic primary due to her consistent polling edge—such as 23% to Maura Sullivan's 9% in the August 2025 Saint Anselm survey—bolstered by endorsements from U.S. Senators Jeanne Shaheen and Maggie Hassan, plus labor unions like SEA/SEIU Local 1984, and strong name recognition from her Portsmouth City Council tenure and family political legacy. Recent Q1 FEC filings through March 31 show Sullivan ahead in total raised ($2.6 million vs. Shaheen's $1.8 million) and cash on hand ($1.5 million), sustaining her at 30.5% as a credible challenger with Marine veteran credentials. Lower odds for Carleigh Beriont (8.5%) and Heath Howard (8.1%) reflect their modest fundraising ($385,000 and $34,000) and minimal poll support, amid an open seat race ahead of the September 8 primary.
