As of mid-2026, seven Republican senators have announced they will not seek re-election in the upcoming cycle, establishing the clear market leader at 77 percent. Key retirements include Thom Tillis of North Carolina, Joni Ernst of Iowa, Steve Daines of Montana, Cynthia Lummis of Wyoming, and others confirmed through mid-year, aligning precisely with the current tally of Republican-held Class II seats. This total reflects standard patterns of voluntary departures driven by age, personal considerations, or shifts to other roles, without additional late announcements or primary challenges altering the count. Traders assign modest probability to scenarios with five, six, eight, or nine departures, which would require unexpected reversals or new exits before filing deadlines. The distribution underscores the stable pace of Senate retirements observed in recent cycles.

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.
