Former U.S. Sen. John E. Sununu's commanding lead in recent New Hampshire Republican Senate primary polls—widening over former Sen. Scott Brown per UNH Survey Center (April 23) and Washington Examiner reporting (May 7)—has driven trader consensus to 88.5% implied probability for him as the September 8 nominee in the open race vacated by retiring Sen. Jeanne Shaheen. Sununu benefits from establishment backing like NRSC promotion, family name recognition, prior incumbency, and state Sen. Dan Innis's September 2025 dropout and endorsement, positioning Innis at 8.6% on residual support. Brown, emphasizing outsider credentials, holds 7.3% amid niche MAGA grassroots endorsements like NH4TRUMP's May 13 nod, while brother Chris Sununu's 1.6% reflects his April 2025 declination.

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.
