This market resolves clearly based on which party wins Pennsylvania's 3rd congressional district in the November 2026 midterm elections. The rules specify how to treat party affiliation for ballot-listed candidates as well as non-major-party candidates via their stated caucusing intentions. Resolution relies primarily on a consensus of credible reporting, with a designated official backup—the Federal Election Commission—if any ambiguity arises. While evaluating media consensus involves some discretion, standard election outcomes for US House seats are unambiguous, and the rules clearly outline the fallback path to official government certification.

Resolution rules

This market will resolve according to the party of the candidate who wins the PA-03 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/).
