This market clearly defines how the winning party is determined for the 2026 PA-01 House election, including explicit provisions for independents or non-major party candidates based on ballot affiliation or caucus intent. Resolution relies primarily on a consensus of credible media reporting, which involves some discretion in determining when calls are conclusive, but it includes a clear fallback to official results from the Federal Election Commission in ambiguous cases.

Resolution rules

This market will resolve according to the party of the candidate who wins the PA-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/).
