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 59% implied probability in the NH-01 Democratic primary, driven by her frontrunner status in recent American Research Group polling (41% support) and superior fundraising exceeding $500,000, bolstered by endorsements from EMILY's List and family ties to Sen. Jeanne Shaheen enhancing name recognition among primary voters. Maura Sullivan holds 22.5% on her Navy veteran background and prior 2020 bid experience, while Carleigh Beriont's 11% reflects grassroots progressive appeal and Heath Howard's 5.2% stems from local activism. No major shifts in the past 48 hours, but upcoming debates and ad blitzes ahead of the September 10 primary could tighten the race in this incumbent-open district contest following Chris Pappas's Senate pivot announcement.
