Seven Republican senators are confirmed as not seeking re-election in 2026, producing the current 77.5% market weighting on that total. Retirements announced between late 2025 and March 2026 by Mitch McConnell, Thom Tillis, Joni Ernst, Steve Daines, Cynthia Lummis, Tommy Tuberville (pursuing the Alabama governorship), and appointed Sen. Alan Armstrong account for the bulk of the figure. Two additional open seats resulted from primary defeats of John Cornyn and Bill Cassidy in May, with no further Republican Senate retirements or defeats reported since. Traders have priced in the absence of new developments through mid-August, while assigning modest probabilities to higher counts in the event of late-cycle primary challenges or additional retirement announcements before filing deadlines.

This market will resolve according to the total number of Republican members of the U.S. Senate who are considered to be retiring or not seeking reelection in 2026.
For the purposes of this market, a member may be considered not to seek reelection if:
• They publicly announce they are retiring from Congress and will not run for reelection to their current seat
• They choose to run for a different elected office in 2026 instead of running for reelection to their current seat
• They do not seek their party’s nomination for reelection to their current seat, meaning they neither file for reelection nor participate in their party’s nominating process (such as a primary, convention, or caucus)
Only members whose current term is scheduled to end with the 2026 regular election for the Senate may qualify for this market.
This market will not resolve until after the relevant final 2026 candidate filing deadline has passed in all states, which is expected to occur in late August 2026.
The resolution source for this market will be a consensus of credible reporting.
