John E. Sununu holds a commanding lead in New Hampshire’s Republican Senate primary due to his prior service representing the state in Congress and the Senate, established name recognition, and consistent polling margins of roughly 35–39 points over former Massachusetts Senator Scott Brown in recent surveys from UNH and Saint Anselm College. Brown remains the clearest alternative but has shown limited traction. Chris Sununu, the former governor and John’s brother, withdrew early, while state Senator Dan Innis endorsed Sununu and exited the race. With the September 8 primary one month away and filing deadlines passed, traders price in low odds of an upset absent major late developments such as health issues or unexpected endorsements that could alter turnout dynamics.

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.
