The rules, in plain English

This market resolves based on who wins the 2026 Kansas U.S. Senate election, including any run-offs. A candidate represents a party if they are that party's nominee. Other candidates like Greens, Libertarians, or independents may be added later. Independent candidates don't count as Democrat or Republican, even if they have party ties. Candidate names in the contract are 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. The market uses Associated Press, Fox News, and NBC as sources. It resolves when all three call the race for the same candidate. If they don't all call it for the same candidate, it resolves based on official certification.

What the rules leave open

  • What happens if the Republican nominee withdraws or dies after being named but before election day and no replacement is formally nominated
    closest the rules come: “In the event that any named candidate is replaced as the nominee of their respective party prior to election day, the name in the contract will be updated and the market will resolve based on the replacement nominee of the party.” · market rules ↗
  • Which body's certification counts as 'official certification'
    closest the rules come: “If all three sources haven't called the race in this state for the same candidate, this market will resolve based on the official certification.” · market rules ↗
