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

**Stage 1 — Blind analysis (ignore market price):**

Based solely on the facts: multiple credible outlets and anonymous sources in late June 2026 report that Justice Alito is *not* expected to retire this Supreme Court term; NPR retracted an erroneous retirement story; the Court and Alito's camp have denied retirement reports; and reporting that Alito is hiring clerks for the next term strongly signals intent to continue serving. These concrete, contemporaneous signals make a near-term (this fall/this term) retirement very unlikely.

Looking out across the remainder of Trump's presidential term (through 20 Jan 2029), the principal drivers that could still produce a resignation are health deterioration, an unforeseen personal scandal, or a voluntary decision to time a retirement for political reasons. Alito is in his mid-70s; while age increases baseline retirement risk, many justices continue into their late 70s and 80s. Historically, Supreme Court retirements within a single four-year presidential term for a justice in this cohort are uncommon but not impossible. Given the present denials, active clerk hiring, and political incentives (Trump has publicly hoped Alito remain; conservative benches generally prefer retiring under ideologically aligned presidents but Alito's current posture suggests no plan), the balance of evidence points to a low probability of resignation at any point during the next ~2.5 years and only a modest probability over the full four-year window.

Synthesizing these factors I assign an independent probability of **18%** that Alito resigns at any time during Trump's term. This reflects the small but non-negligible risk from unexpected health or personal developments over a multi-year window, while heavily weighting the contemporaneous denials and active steps showing intent to stay.

**Stage 2 — Market calibration (compare to current market price Yes=70%):**

The market price (Yes 0.70) values Alito resigning during Trump's term at 70%, which is wildly higher than my independent 18% estimate. Possible reasons the market is pricing so aggressively:

- **Overreaction to earlier (now-retracted) reporting:** The erroneous NPR story and the flurry of speculative pieces likely created momentum that traders who saw the initial headlines did not unwind after retractions/denials. Markets sometimes anchor to breaking headlines and fail to fully incorporate later corrections. - **Information confusion / question misreading:** Some traders may be conflating "this Court term" rumors (which briefly suggested an immediate retirement) with the entire presidential term, or may be trading correlated events (bets on other justices) and using Alito as a proxy. - **Herding and event-driven risk appetite:** High-volume positions (91k contracts) suggest either a concentrated speculative bet or automated strategies that rapidly pushed the price before fundamentals were reassessed. - **Perceived asymmetric tail risk / insider rumors:** A subset of market participants may be pricing in a low-probability, high-impact private signal (health issue or an off-the-record tip). Even if such signals are plausible, public reporting in late June explicitly denied imminent retirement; absent corroborated new information, the market's implied confidence is not supported by public facts.

Conclusion on mispricing: the market appears significantly overpricing the probability of Alito resigning during Trump's term. If you accept my independent assessment, this represents a clear divergence and thus a potential trading opportunity (short Yes / buy No). However, if you believe there is credible private information not yet public, the market could be correctly reflecting that. Given current public evidence, the more rational calibration is far below 70%.
