The rules clearly specify that the outcome depends on which party wins the Iowa 4th Congressional District seat in the 2026 midterm elections. Party affiliation is determined primarily by ballot listing, with a defined fallback to declared caucus intent for independent or third-party candidates. Primary resolution relies on a consensus of credible reporting, which leaves some latitude in determining when a consensus is reached, but the rules include a formal backstop to official Federal Election Commission certified results if any reporting ambiguity arises.

Resolution rules

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/).
