This market will resolve according to the winner of the Republican Primary for United States Senator from New Hampshire. If no 2026 New Hampshire Republican 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 Republican party, however an overwhelming consensus of credible reporting may suffice.Former U.S. Senator John E. Sununu's recent announcement to seek the Republican Senate nomination in New Hampshire has propelled him to dominant trader consensus at 89.5%, reflecting his strong name recognition, prior statewide service from 2003-2009, and familial ties to popular outgoing Gov. Chris Sununu, who has publicly encouraged a competitive primary but ruled out his own candidacy multiple times. Scott Brown's 5.3% share stems from speculation around his past Senate bids, including a narrow 2014 loss, while Dan Innis at 3.1% draws from his recent congressional runs without broader momentum. Chris Sununu lingers at 1.5% despite firm denials, as traders price in low-probability scenarios like a late entry reversal. With the September 2026 primary distant, early positioning and lack of other major announcements solidify Sununu's lead amid NH's open-seat dynamics replacing retiring Sen. Jeanne Shaheen.
