This market resolves cleanly based on the winning candidate's party affiliation for Colorado's 5th congressional district in the 2026 midterms. The rules clearly define how party affiliation is determined, including how independent or third-party candidates are handled via their stated caucus intent. Resolution relies on a consensus of credible media reporting, backed by official Federal Election Commission certified results if any reporting ambiguity arises. While relying on a consensus of reporting introduces some decider discretion before official certification, standard US congressional election outcomes are generally straightforward and unlikely to cause surprise.

Resolution rules

This market will resolve according to the party of the candidate who wins the CO-05 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/).
