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.Former President Joe Biden's endorsement of Dan Koh on May 4—complete with a video call shared by the candidate—has cemented Koh's dominance in trader consensus for Massachusetts' open 6th Congressional District Democratic primary, implying an 80% win probability. Incumbent Rep. Seth Moulton is vacating the seat to challenge Sen. Ed Markey, creating a crowded field of over 10 candidates ahead of the September 1 contest. Koh, a former Biden White House deputy assistant for intergovernmental affairs, benefits from prior backing by VP Kamala Harris, ex-Energy Secretary Jennifer Granholm, Boilermakers Local 29, and local officials like Peabody City Councilor Julie Daigle, signaling strong establishment momentum that has sidelined challengers like Diann Slavit Baylis despite the multicandidate dynamics.
