This market resolves based on which party wins the 2026 midterm election for Iowa's 1st Congressional District. Resolution primarily relies on a consensus of credible reporting, with official Federal Election Commission results serving as a clear fallback if reporting is ambiguous. The rules explicitly define how candidate party affiliations and non-major-party caucus intentions are evaluated, leaving little room for conflicting interpretations or unexpected outcomes.

Resolution rules

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

Market explained

This market measures whether the Republican Party will win Iowa's 1st congressional district (IA-01) House seat in the 2026 midterm elections. Candidates without a major party label are classified based on their stated caucusing intent.

How it resolves

The market resolves to Yes if a candidate affiliated with the Republican Party wins the IA-01 U.S. House seat in the 2026 midterm elections. The market resolves to No if a candidate affiliated with another party wins the seat. A candidate's party is determined by their ballot-listed or identifiable affiliation when all 2026 House elections are conclusively called. A candidate lacking a Democratic or Republican ballot listing is assigned to a party based on their most recently expressed intent to caucus. Resolution is decided by a consensus of credible reporting, or by official Federal Election Commission results if ambiguity exists.
