Resolves YES if after the 2026 United States elections members of the Republican party have won at least 51 seats in the Senate, or 50 seats with a Republican Vice President for tie-breaking purposes. Resolves NO otherwise.

If a politically independent/third-party senator is elected, they would count as a Republican for the purposes of this market if they are widely expected to caucus with the Republican party.
