KalshiRules
This market resolves to the party of the winner of the 2026 election for U.S. Representative for Massachusetts' 3rd congressional district — the term beginning January 3, 2027.
- Which round counts: the November 3, 2026 general election (plurality winner).
- Primaries do not count.
- Party rule: the winner's party is the party on whose line or with whose party designation they appear on the official general-election ballot.
- A candidate nominated by Democratic Party or Republican Party who also appears on other parties' lines (fusion) counts as that party's candidate.
- Candidates who are independent, have no party preference, or belong to any other party resolve to "the named outcome", even if they say they would caucus with a major party.
