Former Senator John E. Sununu dominates trader consensus at 88% implied probability for the New Hampshire Republican Senate primary on September 8, driven by his commanding leads in recent polls, including a University of New Hampshire survey from mid-April showing him at 56% against Scott Brown's 19%, up significantly since late 2025. His October 2025 campaign launch, endorsements from groups like Americans for Prosperity Action, and the prominent Sununu family political dynasty—bolstered by brother Chris Sununu's decision against running in April 2025—have solidified his frontrunner status amid an open seat following Jeanne Shaheen's retirement. Scott Brown trails with prior Massachusetts ties drawing skepticism, while Dan Innis and lingering Chris Sununu speculation hold minimal support; upcoming debates could test dynamics in this competitive primary path to the general election.
