In the 2026 Massachusetts Democratic Senate primary, voters will choose between candidates including Seth Moulton. The market tracks whether Moulton achieves specific vote percentage thresholds based on certified results.
Multiple thresholds (25%, 30%, 35%, 40%, 45%, 50%, and 55%) determine market resolution. The percentage of valid votes Moulton receives, calculated as (votes for Moulton ÷ total valid votes) × 100 and rounded appropriately, must fall within any of these thresholds for a 'Yes' outcome. Resolution depends solely on certified results; preliminary figures, write-in votes (if certified), and adjustments from recounts are considered. If the election is canceled, postponed past expiration, or no certified results exist, the market resolves to 'No'.
This market resolves around Sep 1, 2027, with the outcome confirmed once official vote tallies are verified against credible public sources. The final percentage of votes received by the candidate will settle all contracts, closing the market based on authoritative election results reported after ballots are counted. Timing depends on Massachusetts election officials completing the certification process post-election night.
Key events that could shift prices in this market include debate performance, endorsement announcements, fundraising disclosures, and any major gaffes or scandals involving candidates. Media coverage surges, internal polling leaks, and grassroots momentum metrics may also influence trader sentiment. As the primary nears, smaller polling updates and campaign ad spending reports often create short-term volatility, especially if they suggest unexpected shifts in voter preferences.
