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 commanding 79.5% implied probability in the MA-06 Democratic primary stems from his dominant fundraising—leading ActBlue totals—and a recent high-profile endorsement from former President Joe Biden on May 4, which amplified his profile as a White House alum in the open seat vacated by Rep. Seth Moulton for a U.S. Senate bid. Local endorsements, including Swampscott Select Board Chair Katie Phelan three days ago and former Rep. Michael Harrington on May 7, alongside recent candidate forums like the Tri-town DTC event, have sustained momentum ahead of the September 1 primary. Challengers like Rachel Creemers and Tram Nguyen trail at 3-4% due to weaker resources and visibility in the crowded field, reflecting trader consensus on Koh's path to nomination.
