This market resolves clearly based on which party wins the Missouri 4th Congressional District seat in the 2026 midterms. The primary resolution relies on a consensus of credible media reporting, with an explicit official fallback to the Federal Election Commission if results are ambiguous. Specific rules define party affiliation for independent or third-party candidates by looking at ballot listing or stated intent to caucus when all House races are called. Timing and outcome criteria align standardly with election certification.

Resolution rules

This market will resolve according to the party of the candidate who wins the MO-04 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/).
