This market will resolve according to the candidate who wins the nomination for the Democratic Party to contest the MA-06 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The Democratic primary will take place on September 15, 2026. If no nominee is announced by November 3, 2026, 11:59PM ET, this market will resolve to "Other". The resolution source for this market will be a consensus of official Democrat sources, including https://democrats.org/. Any replacement of the nominee before election day will not change the resolution of the market.**Dan Koh's dominant 69% trader consensus in the MA-06 Democratic primary stems from his organizational edge in the open race created by incumbent Seth Moulton's Senate challenge against Ed Markey.** Koh became the first candidate to qualify for the September 1 ballot over the past week by submitting 2,000 signatures across all 39 district cities and towns, bolstering perceptions of grassroots strength. His January fundraising haul of $204,680 outpaced the field combined, complemented by endorsements from former Transportation Secretary Pete Buttigieg and ex-Rep. John Tierney. Kevin Larivee's 12.3% and Moulton's 11.8% reflect competitive positioning in a nine-candidate field lacking public polls, with traders anticipating further consolidation ahead of the primary.
