As of early September 2026, seven Republican senators whose terms end that year—Steve Daines, Joni Ernst, Thom Tillis, Mitch McConnell, Cynthia Lummis, Tommy Tuberville, and Alan Armstrong—have publicly announced they will not seek re-election, either by retiring or pursuing other offices such as governor. This total aligns precisely with the market's near-certain outcome at 100 percent, reflecting the completion of most state filing deadlines and the absence of further retirement announcements in recent months. Primary defeats for two additional Republican incumbents do not alter the count of those who chose not to run. Late reversals of announced plans or unforeseen vacancies remain possible but improbable given the advanced stage of the cycle and historical patterns of Senate retirements.
