Show full assessmentShow less

This market resolves based on which party wins Pennsylvania's 15th congressional district in the 2026 midterm elections. Primary resolution relies on a consensus of credible reporting to determine both the race winner and the point at which all House races nationwide are settled, which gives the decider latitude to determine when consensus is reached. If reporting remains ambiguous, resolution falls back to official Federal Election Commission certified data, which can take months post-election. For candidates not appearing on the ballot as Democrats or Republicans, the rules define party affiliation by their most recently declared intent to caucus at the time all national House elections are called. Overall, the outcome closely tracks standard congressional election results with clear fallback mechanisms for unusual ballot situations.

Resolution rules

This market will resolve according to the party of the candidate who wins the PA-15 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/).
