Justices Clarence Thomas (78) and Samuel Alito (76), the court's oldest members, have signaled intentions to remain through 2026, aligning with the 74.5% trader consensus against a vacancy. Both sit well below the historical average retirement age near 80, report no acute health issues, and have faced no recent hospitalizations or public pressure sufficient to alter plans. Younger justices including Chief Justice Roberts and Sonia Sotomayor show no retirement indicators. With a Republican Senate majority positioned to confirm replacements quickly, the absence of announcements, leaks, or procedural signals in the first eight months of 2026 reinforces expectations that lifetime tenure will hold for the calendar year. Late-term developments remain possible but currently appear limited.
