This market will resolve according to the winner of the Democratic Primary for United States Senator from New Hampshire. If no 2026 New Hampshire Democratic Senate Primary takes place, this market will resolve to "Other". The resolution source for this market will be the first announcement of the results from the New Hampshire Democratic party, however an overwhelming consensus of credible reporting may suffice.
Chris Pappas holds a commanding position in the New Hampshire Democratic Senate primary due to his established record as a U.S. representative, substantial fundraising edge exceeding $4 million compared to his main challenger's limited resources, and endorsements from party leaders including Kamala Harris and retiring Sen. Jeanne Shaheen. Recent University of New Hampshire polling shows him leading Karishma Manzur, though the margin has narrowed amid progressive criticism of his centrist stances on issues like campaign finance and foreign policy. Manzur has drawn support from activist groups and younger voters emphasizing progressive priorities, yet Pappas maintains broad appeal among the state's moderate Democratic base. With the September 8 primary days away, scenarios that could narrow his lead further include unusually high turnout among progressive voters or late-breaking developments, though his structural advantages make such shifts improbable.
