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 holds a narrow lead in the New Hampshire 1st District Democratic primary trader consensus due to her established name recognition as the daughter of retiring Sen. Jeanne Shaheen and prior local government experience in Portsmouth. Maura Sullivan has narrowed the gap through consistent fundraising advantages, including higher quarterly totals and cash on hand, plus veteran endorsements and grassroots events. Recent Saint Anselm College polling shows the race tightening with both candidates in the mid-20s and roughly half of voters undecided ahead of the September 8 primary. Shaheen’s late-August ad attacking Sullivan over out-of-state and pro-Israel donor ties highlights policy and campaign finance contrasts, while Sullivan positions herself as offering generational change against political dynasties. The remaining candidates trail significantly in visibility and resources.
