Show full assessmentShow less

This market clearly defines how the winning party will be determined, including explicit provisions for ballot affiliation and caucus intent for independent candidates. Resolution relies primarily on a consensus of credible reporting once all House races are called, with official Federal Election Commission records acting as a definitive fallback if any ambiguity arises. Election calls can take time, but the mechanics align directly with standard expectations for congressional race outcomes.

Resolution rules

This market will resolve according to the party of the candidate who wins the CA-01 congressional district seat in the U.S. House of Representatives in the 2026 midterm elections. The midterm elections will take place on November 3, 2026. ​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/).
