Which Supreme Court justices will resign during Trump's term?

**Stage 1 — Blind analysis (ignore current market prices):**

- *Context & baseline:* As of 2026-06-29 there is no credible reporting that Clarence Thomas has announced or intends to announce a resignation. He is 78 years old (born 1948), and many Supreme Court justices historically continue to serve into their 80s. That strongly biases the prior toward *not* resigning during a four-year presidential term.

- *Arguments that raise the chance of resignation:* Advanced age increases the probability of a health event or a decision to step down; sudden medical problems or a serious ethics/scandal development could push him to resign rather than remain under continuing scrutiny. There is also a plausible strategic argument: conservative justices sometimes time retirement to a friendly president so that a conservative successor can be appointed. Because Trump is an ideologically aligned president, a strategic retirement is a feasible mechanism for replacement.

- *Arguments that lower the chance:* Justice Thomas has a long history of staying on the bench despite controversy and has given no public signal of wanting to step down. There are no confirmed health or scandal developments in the news corpus provided. Resignation is a discrete, public act that typically has clear precursors (medical leave, statements about legacy, quiet signals to allies) that are absent here.

- *Quantitative intuition:* Starting from a conservative prior that a sitting justice aged 78 will retire within a roughly four-year window, the raw baseline probability is moderate but not large. Adjusting that baseline upward for the presence of a friendly president (increasing incentive to retire) and upward again for the non-zero risk of health or scandal shocks, but then downward for the absence of concrete signals and the particular justice's historical tendency to remain, leads me to an independent estimate in the low-20% range.

**Stage 2 — Market calibration (compare to market prices):**

- The market currently prices "Yes" at 39%. That is materially higher than my independent estimate (22%). Possible reasons for the market price being above my independent assessment: - *Overgeneralization of attrition risk:* Traders may be applying a baseline attrition probability for all justices in the 75–85 age band that is too high for Thomas specifically, conflating statistical mortality/retirement averages with resignation behavior. - *Rumor amplification and asymmetric payoff:* Rumors, misinformation, or viral items (e.g., ambiguous video headlines) can inflate short-term demand for a "Yes" contract even though no credible confirmation exists. With a finite event horizon and significant emotional interest, rumor-driven liquidity can push the price up. - *Portfolio hedging and correlated exposures:* Some traders may buy "Yes" as part of broader event hedges or because they expect at least one conservative justice will leave during the term; this can push up price for Thomas even if the objective probability is lower. - *Information asymmetry:* Some market participants may believe they have private signals (or misread weak signals) about health or internal court dynamics; absent corroboration, I discount those signals but they can move the price.

- Conclusion of calibration: The market appears to be pricing in either a higher-than-justified baseline attrition rate or rumor/private-signal risk. I view the market as likely overpricing the probability of Thomas resigning during this Trump term by a sizable margin.

- Practical implication for traders: If you accept my model and have sufficient conviction, the current market offers a potential value opportunity to short (sell) the "Yes" side or buy "No." However, price movement could be quick on any credible new public information (medical announcement, ethics disclosure, or explicit retirement signal), so position sizing and stop rules are critical.
