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.John E. Sununu holds a commanding lead in the September 8, 2026, New Hampshire Republican Senate primary due to his strong name recognition as a former U.S. senator from the state and consistent polling advantages of 30+ points over Scott Brown. Sununu's local roots, prior service representing New Hampshire in Congress, and emphasis on fiscal discipline and practical governance have solidified trader consensus around his nomination. Brown, a former Massachusetts senator and ambassador, brings national experience but faces structural challenges connecting with Granite State voters despite endorsements and debates highlighting differences on issues like foreign policy and the economy. Chris Sununu and Dan Innis register minimal support. A late surge by Brown or unforeseen primary turnout shifts remain possible but face steep hurdles given current polling aggregates and Sununu's established position in the race.
