Trader consensus on Polymarket heavily favors Democrats at 83% implied probability to win New Hampshire's open U.S. Senate seat, reflecting Rep. Chris Pappas's polling edge in this battleground state. A University of New Hampshire survey from April 17-21 showed Pappas, the Democratic primary frontrunner at 61%, leading Republican leader John E. Sununu 49%-42% among likely voters and Scott Brown 52%-38%. This builds on an earlier Emerson College poll's near-tie, signaling a slight Democratic widening amid Pappas's incumbency advantage from his House seat. New Hampshire's history of Democratic Senate holds—despite Republican gubernatorial control—bolsters the odds, though the September 8 primaries and national midterm dynamics could shift the competitive race before the November 3 general election.
