Trader consensus on Polymarket favors 7 Republican senators (58.5%) not seeking re-election in the 2026 midterms, reflecting historical base rates of 5-8 retirements per cycle among incumbents and early post-election signals without firm announcements. No sitting GOP senator has officially declared retirement in the past 30 days, but Kansas Sen. Jerry Moran recently stated he is "seriously considering" bowing out, amid speculation around aging incumbents like Iowa's Chuck Grassley (91 years old) and others facing Class I seats in battleground or safe states. The new Republican Senate majority and Trump administration transition may encourage exits similar to past midterm waves, with key announcements expected in early 2025 potentially tipping probabilities toward 6-8.

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.
