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 60.5% implied probability to win New Hampshire's 1st Congressional District Democratic primary on September 8, driven by her consistent polling lead—including a January University of New Hampshire survey showing 33% support among likely voters versus Maura Sullivan's 8% and Heath Howard's 10%—and endorsements from every Democratic mayor in the district. Sullivan trails at 26% amid strong Q1 fundraising dominance, with $1.48 million cash on hand as of March 31, bolstering her Marine veteran credentials and Obama administration experience. Recent Manchester forums highlighted debates on health care and foreign policy, while high undecideds in polls leave room for shifts ahead of the open-seat contest left by Chris Pappas's Senate bid.
