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.Maura Sullivan leads the NH-01 Democratic primary with strong trader consensus due to her decisive fundraising edge, reaching over $3.3 million compared to Stefany Shaheen’s roughly $2.2 million, along with veteran endorsements and rapid gains in recent polling. Late August surveys from Saint Anselm and UNH showed Sullivan ahead or statistically tied with Shaheen among likely Democratic voters, with significant undecided support and a combined progressive share that has not consolidated. Shaheen’s early advantage from name recognition as the daughter of retiring Sen. Jeanne Shaheen has eroded amid criticism over external donors and negative advertising on issues like AIPAC contributions. Carleigh Beriont has shown modest grassroots momentum on the progressive wing, while Heath Howard suspended his campaign. With the September 8 primary just days away, Sullivan’s resource and organizational position has solidified her position as the clear frontrunner in market pricing.
