Trader consensus heavily favors the Democratic Party at 92% to win Washington's 1st Congressional District House seat, driven by the district's strong partisan lean—Cook PVI D+15, where Kamala Harris carried 63% in 2024—and incumbent Rep. Suzan DelBene's dominant track record, including 63% victories in the 2024 general and primary. All major forecasters rate it Solid or Safe Democratic, bolstered by DelBene's $1.37 million cash-on-hand as of late March versus challengers' minimal fundraising. With the May 8 filing deadline imminent and the August 4 top-two primary featuring only Democratic primary opponents like Hunter Gordon and Benjamin Kincaid plus one independent so far, no credible Republican has emerged. Upsets could stem from a late GOP recruit advancing to the general, DelBene's primary upset, personal scandal, or a strong Republican midterm wave.

A candidate's party will be determined by their ballot-listed or otherwise identifiable affiliation with that party at the time all of the 2026 House elections are conclusively called by this market's resolution sources. A candidate without a ballot-listed affiliation to either the Democrat or Republican parties will be considered a member of one of these parties based on the party with which they most recently expressed their intent to caucus at the time all of the House elections are conclusively called by this market's resolution sources.
This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the United States government, specifically the Federal Election Commission (https://www.fec.gov/).
