Which Supreme Court justices will resign during Trump's term?
I assess a 30% chance Clarence Thomas resigns during President Trump’s term (Jan 20, 2025–Jan 20, 2029). Age and uncertainty create meaningful tail risk, but historical incentives and his track record point toward him remaining on the bench.
Analysis
**Stage 1 — Blind analysis (independent probability assessment):**
Clarence Thomas (born 1948) will be in his late 70s / early 80s during the window in question. Lifetime-appointed justices typically retire by choice, and their decisions to step down are driven by a few main levers: health/functional capacity, desire to time a successor, personal choice to reduce workload, or a reputational/scandal shock. There is no confirmed public signal that Thomas intends to resign during Trump’s term. Historically, many justices continue serving into advanced age; others time retirements to coincide with ideologically favorable presidents, but that incentive is asymmetric for Thomas: he benefits most from staying on the bench to preserve his influence, unless he faces health or capacity issues that make continuing untenable.
Given no reported health crisis or retirement announcement in the provided context, and weighing the empirical tendency of long-serving conservative justices to remain until clear medical or personal reasons force them out, I place the independent probability at 30%. That reflects a non-trivial but not dominant chance: the 4-year window has meaningful risk (age-related morbidity, unexpected events, or a sudden personal decision) but not the preponderance of evidence needed to put this near 50%.
Key considerations that influence that 30%: - Age creates increased baseline risk of illness or incapacity in a multi-year window, producing nonzero chance of forced or voluntary resignation. - Lack of public signals or preparatory moves (e.g., staff changes, explicit hints about retirement timing) lowers probability. - Strategic incentives to remain: a conservative justice typically prefers to retain the seat rather than free it up, absent acute triggers.
**Stage 2 — Market calibration (why the market might differ):**
Current market: Yes 0.42 / No 0.58 (volume ~71.8k). My independent 30% probability is materially lower than the market's 42% Yes price. Possible reasons the market is pricing higher:
- *Heuristic/age anchoring:* Traders may overweight age as a signal and treat late-70s as meaning 'likely to leave' in a 4-year span; this produces higher Yes prices than a careful historical/incentive-based read.
- *Tail-risk/insurance demand:* Political participants who would suffer from an unexpected resignation (or who hold correlated positions) may buy Yes as insurance, pushing price up above objective probability.
- *Correlation with other markets:* Traders anticipating multiple resignations under Trump (or betting on other justices) might buy Thomas-Yes as part of a bundle, lifting its price relative to standalone probability.
- *News-sensitivity and liquidity flows:* Any small, ambiguous health report or activist whisper could produce outsized betting shifts; market makers widen spreads to reflect uncertainty, which can show up as higher midprice.
Given this gap, if you accept my 30% estimate, selling Yes (or buying No) at 0.42–0.58 offers positive expected value: the fair price should be near $0.30 for Yes and $0.70 for No. However, the market may move sharply on a single reliable report about Thomas’s health or retirement intentions, so position sizing and stop rules are important.
Bottom line: I judge resignation during Trump’s term plausible but not more likely than not; the market currently overstates that probability by ~12 percentage points relative to my independent assessment, likely because traders overweight age-based heuristics and tail-insurance demand.
Arguments
For
- Age-related risk: he will be in his late 70s / early 80s during the term, which raises baseline chance of health or capacity-driven departure within four years.
- Single adverse health incident or sudden medical diagnosis could force a resignation in a short window.
- Personal or family considerations could lead to a voluntary retirement unexpectedly early in the term.
- Political calculation: if Thomas privately believed stepping down sooner would better secure a favored successor under Trump (unlikely but possible), he might choose to resign.
Against
- No public indication or preparatory signals suggesting retirement—absence of evidence argues toward continuation.
- Strong incentive to remain: conservative justices with long tenures often prefer to retain their seat to preserve judicial influence rather than risk creating a vacancy.
- Historical pattern: many justices serve into advanced age and only step down after clear medical decline; this reduces the chance of a mid-term surprise resignation.
- Thomas’s public posture and behavior historically show a tendency to persist in office rather than step aside preemptively.
Key drivers
- Thomas's age and general health trajectory over 2025–2029
- Any authoritative signal from Thomas, his clerks, or the Court about retirement plans
- Political incentives to time a retirement (or to avoid creating a vacancy)
- Unexpected shocks: major health events, scandal, or family/personal reasons
Risk factors
- Sudden severe health event or incapacitation (medical emergency) during the term
- Unanticipated reputational or legal developments that could prompt immediate resignation
- High market sensitivity to minor/ambiguous signals producing overreactions
- Low transparency from the Court and Thomas’s private circle, making market updates lopsided
Scenarios
Best case
Yes occurs: An unexpected but clear trigger (e.g., acute medical event, documented incapacity, or a deliberate announcement) leads Thomas to resign early in Trump’s term. Trump or a like-minded Senate confirms a conservative successor quickly, preserving conservative jurisprudence and validating market moves that had priced a higher resignation probability.
Most likely
Thomas stays but faces increasing public and private health scrutiny; he may reduce his public workload or take sick days but does not formally resign. No clear retirement announcement is made during the 2025–2029 window, and the seat remains occupied, keeping the Court composition stable.
Worst case
No outcome prevails: Thomas remains on the bench throughout Trump’s term and possibly beyond. Markets that priced a higher resignation probability suffer losses; political actors who hoped for a replacement must wait longer, and any hedges premised on a vacancy fail. A false signal or rumor could have previously caused temporary volatility and losses for traders positioned for resignation.
