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 commanding position in the September 8, 2026, Democratic primary for New Hampshire’s 1st Congressional District due to consistent polling leads, extensive local endorsements, and robust fundraising that exceeds $2.2 million total with over $1.2 million cash on hand reported in July. As the daughter of retiring Sen. Jeanne Shaheen and a former Portsmouth official, she has consolidated support from unions, mayors, healthcare groups, and Democratic organizations in the open-seat race following Rep. Chris Pappas’s Senate bid. Maura Sullivan, a Marine veteran and former Obama administration official who previously ran in 2018, has narrowed the gap somewhat through strong quarterly fundraising hauls and recent polling movement but remains well behind. Lesser candidates including state Rep. Heath Howard and Carleigh Beriont trail significantly with minimal reported momentum or resources. Upcoming late-summer polling and candidate forums before the primary filing deadline could still influence final voter consolidation.
