Chris Pappas secured a decisive victory in New Hampshire’s open Senate seat on November 3, 2026, defeating John E. Sununu by roughly 60 percent to 38 percent with early returns and prompting an immediate concession. The race for the seat vacated by retiring Democratic Sen. Jeanne Shaheen had been viewed as competitive, with Sununu leveraging family name recognition and Republican efforts to flip the seat amid broader midterm dynamics. Pappas’s strong performance in a state that has favored Democrats in federal contests since 2010 drove trader consensus to near-certainty. With the outcome confirmed by projections and concession, the primary remaining factors involve standard certification processes; any alteration would require extraordinary developments such as widespread recount discrepancies or successful legal challenges, both considered remote given the margin.
