Which Supreme Court justices will resign during Trump's term?
I think there is a meaningful chance Alito steps down during Trump’s term, but not as high as the market suggests. My independent estimate is 43%, with the biggest reason being that he is old enough that an ordinary retirement window exists, while the strongest reason against is that he has every incentive to stay unless health or personal factors force the issue.
Analysis
Samuel Alito is 76 as of today, which puts him squarely in the age range where voluntary retirement becomes plausible, especially on a Court where justices often think strategically about timing. Because Trump is in office and the end of the term is still more than two years away, there is a real opportunity for Alito to choose the politically favorable moment to leave and lock in a replacement. That said, nothing in the available context suggests imminent departure, and the Court’s modern norm is that justices often stay well past conventional retirement age unless health, family, or other personal considerations push them out.
The case for a resignation is strengthened by ideology and timing. Alito is one of the most conservative members of the Court, and if he wants to preserve his legacy or avoid the risk of an unfavorable future administration, this is a rational window to exit. But the decision is not automatic: leaving now means giving up the influence and status of an active justice, and many justices in his position prefer to keep serving as long as they can. Absent news of health issues or a public signal that he is preparing to step down, the base rate for an actual resignation over a roughly two-year horizon is still well below certainty.
The market’s 64% Yes price looks somewhat aggressive to me. It appears to assume that age plus Republican control make retirement more likely than they usually are in practice. I think the market may be overweighting strategic retirement incentives and underweighting just how durable Supreme Court tenure tends to be. My estimate is lower because the most likely outcome is that Alito simply stays on the Court through most or all of Trump’s term unless a specific catalyst emerges.
Arguments
For
- He is old enough that retirement during the next few years would be unsurprising.
- Trump’s presidency gives him a favorable political moment to step down and shape his replacement.
Against
- There is no public indication that he intends to resign soon.
- Supreme Court justices frequently serve far longer than ordinary retirement norms would predict.
Key drivers
- Alito’s age makes a voluntary retirement window plausible within Trump’s term.
- A Republican presidency gives him a strong incentive to time a departure strategically if he is inclined to leave.
- Supreme Court justices often remain in office despite advanced age, lowering the baseline probability of resignation.
Risk factors
- Unexpected health or family developments could force an earlier resignation than expected.
- A private decision to preserve conservative succession could lead him to retire sooner than the historical baseline suggests.
Scenarios
Best case
Alito chooses to retire while Trump is still president, likely for strategic or personal reasons, allowing a conservative successor to be confirmed.
Most likely
Alito continues serving for now, with resignation possible but more likely to hinge on health, stamina, or a late strategic retirement decision than on age alone.
Worst case
He remains on the Court through the end of Trump’s term, with no resignation until after January 2029 or not at all during the period.

The exclusion of Navier-Stokes from resolution is the key reason the zero-solved outcome still looks likelier than not.
