Market rules
"Yes" if, as a result of the U.S. Senate midterm elections on November 3, 2026, the Republican Party retains a majority of seats (51 or more out of 100), according to the aggregated data on the Wikipedia page "2026 United States Senate elections" as of November 10, 2026. Otherwise, "No". Races that are not definitively determined (recounts, legal disputes) as of the date of the resolution will be considered based on the current candidate leading.
