The rules, in plain English
This market resolves based on who wins the 2026 Iowa U.S. Senate election, including any run-offs. A candidate represents a party if they are that party's nominee. Third-party candidates like Greens, Libertarians, or independents may be added later. Candidates running as independents do not count as Democrats or Republicans, even if they have party affiliations. Candidate names may be listed for convenience. If a named candidate is replaced as their party's nominee before election day, the name will be updated and the market resolves based on the replacement nominee. The market resolves when the Associated Press, Fox News, and NBC all call the race for the same candidate. If all three don't call it for the same candidate, it resolves based on official certification.
