In the open Massachusetts 6th Congressional District Democratic primary set for September 1, 2026, trader consensus on Polymarket gives former Boston Mayor chief of staff Dan Koh a 72% implied probability of victory, driven by his record-breaking $2 million-plus fundraising haul in the campaign's first quarter, continued cash dominance through February, and status as the first candidate to qualify for the ballot on March 26. Incumbent Rep. Seth Moulton's Senate challenge to Ed Markey has left the seat vacant, boosting the crowded nine-Democrat field, but Koh's endorsements from Pete Buttigieg and ex-Rep. John Tierney solidify his frontrunner edge amid recent forums highlighting health care and immigration divides. Lower odds for challengers like Seth Moulton (12%) reflect slim chances of a late switch-back, with no public polls yet available and the August 25 filing deadline looming as a potential catalyst.
