This market resolves on standard terms for a US House race in the 2026 midterms. Resolution initially relies on a consensus of credible reporting, with an explicit official fallback to certified results from the Federal Election Commission if any ambiguity arises. The rules clearly define how candidate party affiliations are established, including how to handle independent candidates via their stated caucusing intentions once all House races are called. Timing is tied to standard election certification cycles, presenting minimal risk of unexpected outcomes.

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.
