The question, as the venue words it

Will the number of the 13 Republican-favored 2026 U.S. Senate general elections (including special elections) listed in the Additional Details won by a nominee of the Republican Party be at least 12 at the November 3, 2026 general election?

How this market settles

If the number of the 13 Republican-favored 2026 U.S. Senate general elections (including special elections) listed in the Additional Details won by a nominee of the Republican Party is at least 12 at the November 3, 2026 general election, then the market resolves to Yes. The Republican-favored races are the 13 2026 U.S. Senate general elections (including special elections) in the states that the Cook Political Report rated Solid Republican or Likely Republican in its Senate race ratings dated Oct 30, 2026: Alabama, Arkansas, Florida, Idaho, Kentucky, Louisiana, Mississippi, Montana, Oklahoma, South Dakota, Tennessee, West Virginia and Wyoming. The Florida race is the special election. That list is fixed as of Issuance, so later rating changes do NOT add or remove a race. The count is the number of those 13 races won by a nominee of the Republican Party. A candidate who wins as an independent, or under a fusion, minor-party, or write-in line without being the Republican Party's own nominee, does NOT count, even if no Republican Party nominee appeared on the ballot. If a runoff is required to determine the winner of any race, the runoff result governs.

What could still go wrong

  • The term 'nominee of the Republican Party' requires a clear official definition — it is unclear whether a candidate who appears on both a Republican and minor-party line (fusion ticket) qualifies as the Republican nominee, though the description partially addresses this by excluding candidates winning solely under a non-Republican line.
  • If any race requires a runoff that is not completed before the market end date of 2026-12-15T14:59:00Z, resolution could be delayed or disputed.
  • The Cook Political Report ratings are fixed as of issuance (Oct 30, 2026 ratings referenced), but the market was issued before that date, creating a potential ambiguity if the Oct 30, 2026 ratings differ from expectations at issuance.
  • No explicit source is specified for determining the official winner of each race beyond the general election result, leaving room for disputes in close or contested races.
