## Question
Will any U.S. Supreme Court justice announce their retirement before September 1, 2026?
## Description / Resolution Criteria
## Description
On June 30, 2026, NPR [retracted](https://www.npr.org/2026/06/30/nx-s1-4622951/samuel-alito-retires) a story reporting that Samuel Alito, age 76, was retiring. There has been similar [speculation](https://www.cbsnews.com/news/supreme-court-justices-alito-thomas-not-retiring-sources-say/) about Clarence Thomas, 78, retiring. Amy Coney Barrett, though only 54, has faced [calls](https://www.dailymail.com/news/article-15942533/trump-amy-coney-barrett-birthright-citizenship.html) from conservative media to resign due to her opinions on recent cases such as birthright citizenship and whether the executive branch of the federal government can overrulse state laws on mail-in balloting. 
Supreme Court justices serve a [life tenure](https://www.brennancenter.org/our-work/analysis-opinion/life-tenure-us-supreme-court-justices-global-oddity-clear-costs) and are confirmed by a simple majority of the Senate. Thus, if Democrats were to take control of the Senate in the [2026 elections,](https://en.wikipedia.org/wiki/2026_United_States_Senate_elections) President Donald Trump would need Democratic senators to approve of any of his Supreme Court nominations. 
At the time of this question, Republicans control the U.S. Senate 53-47, a majority of 6 seats. However, Metaculus [assigns](https://www.metaculus.com/questions/36370/us-senate-plurality-after-2026-midterms/) Republicans only a 55% chance of retaining the chamber. Republicans face a difficult [map](https://www.270towin.com/2026-senate-election/) in the 2026 cycle, defending contested seats in North Carolina, Georgia, Ohio, Maine, and perhaps Texas and Iowa. Democrats are defending New Hampshire and Michigan. Historically, the out-of-power party often has an advantage in midterm elections. (See, e.g., the Brookings analysis [What history tells us about the 2026 midterm elections](https://www.brookings.edu/articles/what-history-tells-us-about-the-2026-midterm-elections/).)
`{"format": "metac_reveal_and_close_in_period", "info": {"post_id": 44395, "question_id": 44406}}`
## Resolution Criteria
This question resolves as **Yes** if any of these Justices before September 1, 2026 announces or confirms their intention to retire, resign or permanently leave active service on the United States Supreme Court:
* Chief Justice John Roberts
* Associate Justice Clarence Thomas
* Associate Justice Samuel Alito
* Associate Justice Sonia Sotomayor
* Associate Justice Elena Kagan
* Associate Justice Neil Gorsuch
* Associate Justice Brett Kavanaugh
* Associate Justice Amy Coney Barrett
* Associate Justice Ketanji Brown Jackson
## Fine Print
Please note that the justice need not leave office before September 1, 2026, and conditional requirements before they leave, such as requiring the confirmation of their successor to happen first (as occurred with Justices[ Sandra Day O'Connor](https://www.supremecourt.gov/publicinfo/press/pr_07-01-05.html) and [Stephen Breyer](https://abcnews.com/Politics/read-justice-stephen-breyers-retirement-letter/story?id=82509050)), count.
***
This question's information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44395) which opened on 2026-07-01 09:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question's resolution could have been known before this question opened, then this question will be annulled.
## Sub-question decomposition
- (w=0.50) Will Clarence Thomas or Samuel Alito announce retirement/resignation before September 1, 2026? — The two oldest justices (78 and 76) are the primary retirement speculation targets amid a Republican Senate and potentia
- (w=0.15) Will Amy Coney Barrett announce retirement/resignation before September 1, 2026? — Facing conservative calls to resign, though she is only 54 and voluntary resignation would be highly unusual.
- (w=0.35) Will any of the other six justices (Roberts, Sotomayor, Kagan, Gorsuch, Kavanaugh, Jackson) announce retirement/resignation before September 1, 2026? — Covers remaining justices; liberal justices unlikely to hand Trump a pick, others healthy, but captures unexpected event
Combination rule: **independent_or**

## Cross-Market Signals
### No signal found
Information gaps:
- No health-status data on younger liberal justices (Sotomayor)
- No polling on 2026 Senate control affecting timing incentives
- Historical base rate confidence relies on a single code estimate
- No confirmation of any pending private retirement plans
Key uncertainties:
- Whether Alito reverses course before Sept 1 despite denials
- Whether Thomas surprises given age and tenure milestone
- Impact of pre-midterm political pressure on GOP-aligned justices
- Possibility of sudden health-driven departure by any justice
## Required pre-forecast walkthrough
Before giving probabilities, walk through these explicitly:
(a) The time left until the question resolves.
(b) The status quo outcome — what happens if nothing changes from today.
(c) A brief scenario that results in NO.
(d) A brief scenario that results in YES.
## Calibration guidance
- **Estimate each sub-question in isolation.** Do not let your answer to one sub-question anchor your answer to another. This is the core of Fermi decomposition — independence forces more careful reasoning per factor.
- **Anchor on the status quo.** Require strong specific evidence to move far from it.
- 0.05 / 0.95 require strong, multi-source evidence. Avoid >0.97 or <0.03 unless the outcome is already settled or near-tautological — overconfident misses are punished heavily by the log score.
- **Anchor on prediction markets.** If liquid market prices (Polymarket / Kalshi) or a community forecast appear in the evidence, treat them as a strong, well-calibrated prior. Your final estimate should rarely sit more than ~15 percentage points from a liquid market on the SAME question — move further only with specific evidence the market lacks.
- **Treat research as fallible, not ground truth.** A single-source or "very recent" claim — especially one the evidence flags as unverified, possibly AI-generated, or low-credibility — must not drive you to near-certainty. When a load-bearing fact is unverified, keep at least 10-15% on the chance it is wrong.
- **Also provide a holistic estimate** — your overall gut feeling about the main question, BEFORE you see the mathematical combination. This serves as a sanity check: if the Fermi result and holistic estimate diverge wildly, something is wrong.

There has been similar [speculation](https://www.cbsnews.com/news/supreme-court-justices-alito-thomas-not-retiring-sources-say/) about Clarence Thomas, 78, retiring. Amy Coney Barrett, though only 54, has faced [calls](https://www.dailymail.com/news/article-15942533/trump-amy-coney-barrett-birthright-citizenship.html) from conservative media to resign due to her opinions on recent cases such as birthright citizenship and whether the executive branch of the federal government can overrulse state laws on mail-in balloting.\u0026#x20;\n\nSupreme Court justices serve a [life tenure](https://www.brennancenter.org/our-work/analysis-opinion/life-tenure-us-supreme-court-justices-global-oddity-clear-costs) and are confirmed by a simple majority of the Senate. Thus, if Democrats were to take control of the Senate in the [2026 elections,](https://en.wikipedia.org/wiki/2026_United_States_Senate_elections) President Donald Trump would need Democratic senators to approve of any of his Supreme Court nominations.\u0026#x20;\n\nAt the time of this question, Republicans control the U.S. Senate 53-47, a majority of 6 seats. However, Metaculus [assigns](https://www.metaculus.com/questions/36370/us-senate-plurality-after-2026-midterms/) Republicans only a 55% chance of retaining the chamber. Republicans face a difficult [map](https://www.270towin.com/2026-senate-election/) in the 2026 cycle, defending contested seats in North Carolina, Georgia, Ohio, Maine, and perhaps Texas and Iowa. Democrats are defending New Hampshire and Michigan. Historically, the out-of-power party often has an advantage in midterm elections. (See, e.g., the Brookings analysis [What history tells us about the 2026 midterm elections](https://www.brookings.edu/articles/what-history-tells-us-about-the-2026-midterm-elections/).)\n\n`{\"format\": \"metac_reveal_and_close_in_period\", \"info\": {\"post_id\": 44395, \"question_id\": 44406}}`\n\n## Resolution Criteria\nThis question resolves as **Yes** if any of these Justices before September 1, 2026 announces or confirms their intention to retire, resign or permanently leave active service on the United States Supreme Court:\n\n* Chief Justice John Roberts\n* Associate Justice Clarence Thomas\n* Associate Justice Samuel Alito\n* Associate Justice Sonia Sotomayor\n* Associate Justice Elena Kagan\n* Associate Justice Neil Gorsuch\n* Associate Justice Brett Kavanaugh\n* Associate Justice Amy Coney Barrett\n* Associate Justice Ketanji Brown Jackson\n\n## Fine Print\nPlease note that the justice need not leave office before September 1, 2026, and conditional requirements before they leave, such as requiring the confirmation of their successor to happen first (as occurred with Justices[ Sandra Day O\u0027Connor](https://www.supremecourt.gov/publicinfo/press/pr_07-01-05.html) and [Stephen Breyer](https://abcnews.com/Politics/read-justice-stephen-breyers-retirement-letter/story?id=82509050)), count.\n\n***\nThis question\u0027s information (resolution criteria, fine print, background info, etc) is synced with an [original identical question](https://www.metaculus.com/questions/44395) which opened on 2026-07-01 09:00:00. This question will resolve based on the resolution criteria and fine print of the linked original question. However, if this question would resolve differently than the original question, then this question will be annulled. Additionally, if the original question\u0027s resolution could have been known before this question opened, then this question will be annulled.",
