Mean of 5 draws (0.11, 0.11, 0.14, 0.14, 0.13). (0) Resolution check: neither the Supreme Court press-release page nor any October 2026 reporting (Bloomberg Law, CNBC, Reuters, Daily Caller) shows a Thomas departure announcement, so nothing has resolved. (a) About 8.8 months remain until the July 1, 2027 deadline, covering the full October Term 2026, which ends in late June. (b) If nothing changes, the answer is No. Thomas is hearing a full docket, has hired clerks for OT'27 (after the deadline), and is plausibly chasing the all-time tenure record on May 20, 2028. People close to him told CBS and ABC in April that he would not retire. (c) NO scenario: he serves through the term without comment and aims for the 2028 record, or a death in office resolves at Kalshi's 'last fair price' rather than as a Yes. (d) YES scenario: a post-midterm scare over Senate control, a negotiated clerk succession with Trump, or a health issue prompts an announcement. Most likely this would be a customary end-of-term notice in spring or June 2027, which still counts because only the announcement date matters. Kennedy's 2018 exit shows that forward clerk hiring is not decisive. The anchors are Kalshi at 14% (bid/ask 12/13) and Polymarket at 14.5% on the same question, two crowds that agree. I shade slightly lower because of the OT'27 clerk hiring, the tenure-record incentive, and Alito's on-record plan to stay through this term, which removes some of the co-retirement pressure.

report: current state
- [2026-10-06] Bloomberg Law reported that the prospect of Democratic control has put renewed focus on the two oldest justices, Alito and fellow conservative Clarence Thomas, 78, though neither has shown any signs of wanting to step down . https://news.bloomberglaw.com/us-law-week/supreme-courts-alito-plans-to-stay-even-if-democrats-win-senate - [2026-10-06] Alito stated "I intend to stick around through this term," Alito, 76, said in an interview last week as the court prepared to open a term that will run through next June , dampening (but not eliminating) co-retirement speculation that often implicates Thomas too. https://news.bloomberglaw.com/us-law-week/supreme-courts-alito-plans-to-stay-even-if-democrats-win-senate - [2026-10-06] CNBC reported Justice Clarence Thomas, 78 — the court's oldest justice and a member of its conservative bloc — has also been on "retirement watch" , but no announcement has been made. https://www.cnbc.com/2026/10/04/supreme-court-justice-alito-thought-about-retiring.html - [2026-10-03] Reuters/AOL reported the new Supreme Court term began Oct. 5, 2026, and noted "Thomas has not addressed retirement rumors, but in the past has hinted at a lengthy tenure." https://www.aol.com/articles/term-gives-us-supreme-courts-100753000.html - [2026-10-03] A political scientist quoted by Reuters said "McMahon said Thomas may want to become the longest-serving justice, a milestone he would reach in May 2028." , implying he aims to stay well past the market's July 2027 close. https://www.aol.com/articles/term-gives-us-supreme-courts-100753000.html - [2026-10-06] Daily Caller reported that Republicans could potentially confirm a younger successor if 76-year-old Alito or 78-year-old Clarence Thomas retired, though neither have expressed interest in leaving the court . https://dailycaller.com/2026/10/06/justice-samuel-alito-staying-democrats-senate-midterm-elections/ - [2026-07 (dated article, ~98 days before Oct 6)] A report summarizing spring reporting noted "In April, both CBS News and ABC News reported that sources close to Thomas said he does not intend to retire during 2026. The reports also said fellow conservative Justice Samuel Alito likewise is not expected to step down this year." https://finchannel.com/is-clarence-thomas-retiring-what-we-know-about-the-supreme-court-justices-future/132130/america/2026/06/ - [2026-04-17] CBS News reported "Sources close to Supreme Court Justice Samuel Alito confirm that he is not planning to retire this year. Sources close to Justice Clarence Thomas also tell CBS News that he does not plan to step down." https://www.cbsnews.com/news/supreme-court-justices-alito-thomas-not-retiring-sources-say/ - [2026-04-16] CNN reported that President Donald Trump seems to be leaning in on the idea that elderly conservative Justices Samuel Alito and Clarence Thomas might think about a conveniently timed retirement this year , reflecting ongoing political pressure despite no plans being confirmed. https://www.cnn.com/2026/04/16/politics/supreme-court-trump-alito-thomas - [2026-06 (Newsweek, ~152 days before Oct 6)] Newsweek noted "Thomas has not indicated when he plans to retire, and justices are under no obligation to time their departures around electoral cycles." https://www.newsweek.com/clarence-thomas-is-closing-in-on-a-scotus-record-timing-is-everything-11918997 - [2026-06-30] An NPR report erroneously claimed a justice (Alito) was retiring; NPR retracted the story, saying a reporter misheard information as the court was delivering the final opinions of its nine-month term , illustrating how volatile and rumor-prone this topic remains, though it concerned Alito, not Thomas. https://news.bloomberglaw.com/us-law-week/supreme-courts-alito-plans-to-stay-even-if-democrats-win-senate - [2026-10-05/06] The Supreme Court's new term (running through June 2027) has begun with Thomas actively sitting and participating, with major arguments scheduled through December 2026 (gun rights Dec. 2, Arizona voter case Dec. 8), indicating no imminent departure plans and a full workload ahead. https://www.aol.com/articles/term-gives-us-supreme-courts-100753000.html BOTTOM LINE: As of October 6, 2026, Clarence Thomas has given no public indication of retirement, multiple outlets (CBS, Reuters, Bloomberg, CNBC) report he shows "no signs of wanting to step down," and he is actively hearing a full docket for the term running through June 2027, with observers noting he may be aiming to become the longest-serving justice in May 2028 — all pointing toward no announcement before the July 1, 2027 deadline, though persistent political speculation (age 78, midterm Senate stakes) keeps some uncertainty alive. NOT FOUND: No statement from Thomas himself (unlike Alito's recent on-record comments) addressing 2026-2027 retirement plans; no Supreme Court official announcement or filing indicating a planned departure; no evidence of health issues affecting his tenure.
report: base rate
- [2024-11-(approx)] Legal analysts speculated Thomas (and Alito) would be pressured to retire during Trump's second term to preserve a conservative seat, with one scholar noting "from the point of view of those who want to keep the court conservative, Thomas, and also Alito, should resign before the summer of 2026 if the Republicans win the White House and the Senate this Election Day." https://www.newsweek.com/clarence-thomas-likely-resign-donald-trump-wins-election-1978005 - [2024-11-(approx)] A separate forecaster, Ed Whelan, predicted "I expect Alito to announce in the spring of 2025 that he will retire from the Court. I think it very likely that Thomas will do the same in the spring of 2026." Neither prediction has materialized as of October 2026. https://thehill.com/regulation/court-battles/4984208-supreme-court-justices-retirement-speculation/ - [2026-04-17] CBS News reported, based on sources close to the justices, that sources close to Supreme Court Justice Samuel Alito confirm that he is not planning to retire this year, and sources close to Justice Clarence Thomas also tell CBS News that he does not plan to step down. https://www.cbsnews.com/news/supreme-court-justices-alito-thomas-not-retiring-sources-say/ - [2026-04-16] CNN noted the historical pattern that "the last seven justices to retire (as opposed to dying in office like Ginsburg or Antonin Scalia) have done so when the party more aligned with them controlled both the presidency and the Senate — and could confirm a like-minded replacement." This favors a window while Republicans hold the Senate. https://www.cnn.com/2026/04/16/politics/supreme-court-trump-alito-thomas - [2026-04-11] US News reported the historical benchmark that experts note discussion of a possible vacancy has increased as the two men draw closer to the average age of retirement for Supreme Court justices since 2000 - about 80 years old ; Thomas turned 78 in June 2026, so he is approaching but not yet at that average. https://www.usnews.com/news/top-news/articles/2026-04-11/for-aging-us-supreme-court-justices-the-politics-of-retirement-looms-large - [Historical/academic] Older academic data (Calabresi & Lindgren) found that between 1971 and O'Connor's retirement in 2006, the average age at which justices left the court—either through death or retirement—was 78.7 years old , and justices are more likely to die in office if the president is not of the same party as the president who appointed them... statistically Supreme Court justices are 168 percent more likely to retire if the incumbent president shares their party — a factor currently satisfied for Thomas (appointed by a Republican, serving under Republican Trump). https://www.sabralawoffices.com/blog/2015/03/what-is-the-age-to-retire-in-the-supreme-court-2/ - [2026-09-(approx)] NBC News reported that despite persistent speculation, "none of the nine justices has signaled plans to retire, but speculation has centered on how long the two oldest justices — conservatives Clarence Thomas, 78, and Samuel Alito, 76 — will stay on the court." https://www.nbcnews.com/politics/congress/democrats-dont-expect-fill-supreme-court-vacancy-trump-rcna600908 - [2026-10-05] Polymarket's "Will Clarence Thomas announce his retirement by...?" market (separate venue, informational only) implies roughly 15-19% for the June 30, 2027 outcome and about 9-10% for Dec 31, 2026, reflecting trader skepticism of a near-term announcement despite the political pressure narrative. https://polymarket.com/event/will-clarence-thomas-announce-his-retirement-byptptpt-20260701190627804 - [2026-07-(approx)] A separate Kalshi market tracker (Federal News Network) cited Thomas's implied resignation probability on Kalshi as having fallen from an early-term high of 67% to roughly 40% over the year, reflecting diminishing market confidence as explicit denials accumulated. https://www.newsweek.com/clarence-thomas-supreme-court-retire-betting-odds-11432312 - [Historical base rate] Of 103 justices who have left the Court, only 56 of them decided to retire, while the other 47 died while in office — meaning voluntary retirement/resignation announcements, while common, are far from universal among exits, and sitting justices in good health frequently choose to serve many additional years past comparable ages (e.g., Holmes retired at 90, Stevens at 90). https://www.sabralawoffices.com/blog/2015/03/what-is-the-age-to-retire-in-the-supreme-court-2/ - [2026-04-21] Legal scholar Ilya Shapiro cautioned that absent a direct statement, speculation should be discounted: "Unless you hear about a retirement from the justice or maybe his wife, I would discount all of it. It's just rumors — based on rumors, based on speculation." https://washingtonstand.com/article/clarence-thomas-and-samuel-alito-unlikely-to-retire-from-supreme-court BOTTOM LINE: The reference class (modern SCOTUS justices retiring under same-party presidents, with higher propensity near age ~79-80 and strong political incentive to time departures) creates a structurally elevated but not high base rate for an announcement in this window; however, the strongest recent and repeated primary-source signal (multiple outlets, sourced to people close to Thomas, through 2026) is an explicit denial of near-term retirement plans, and no justice has yet broken that pattern, suggesting the base rate alone would put this in the "plausible but more likely No" range for a ~9-month remaining window. NOT FOUND: No direct on-the-record quote from Thomas himself in 2026 confirming or denying retirement plans (reporting relies on unnamed "sources close to" him); no official White House or Senate Judiciary Committee statement addressing a Thomas vacancy timeline; could not find a rigorous updated academic retirement-hazard model (post-2006) with a quantified near-term probability for Thomas specifically.
report: yes case
YES means: Clarence Thomas publicly announces or officially communicates his retirement/resignation from the Supreme Court at any point between now (2026-10-06) and July 1, 2027, regardless of when the departure takes effect. - [2026-10-04] Even the most skeptical mainstream coverage concedes Thomas remains on active "retirement watch," with CNBC reporting "Justice Clarence Thomas, 78 — the court's oldest justice and a member of its conservative bloc — has also been on retirement watch." This shows the possibility is still live in reporters' and insiders' framing, not dismissed outright. - [2026-10-03] US News/Reuters coverage confirms the structural mechanism creating urgency: speculation among court watchers has ramped up as the two men draw closer to the average retirement age of about 80, with the November 3 congressional elections looming, and if Democrats take control of the Senate, they could try to block Trump's nominee to fill any vacancy — meaning any rational window for a pain-free confirmation narrows sharply after the midterms, creating a hard incentive to act before mid-2027 while a GOP Senate remains likely intact through the current Congress. - [2026-05-14] A Northeastern University legal-studies feature lays out the single most concrete operative mechanism for a YES: a law professor's observation that the appointment of former clerks provides incentive for retiring justices to help anchor their judicial ideology when they're no longer on the court, with Thomas in particular having plenty of law clerks poised to become the next Supreme Court justice, and it would not be at all surprising to see Trump promise one of them a seat if Thomas resigns now . This is the most plausible causal path to a YES: a negotiated succession (Trump pledges a Thomas clerk's nomination) could trigger an announcement well before the deadline. - [2026-05-14] The same piece quotes a law professor describing the urgency calculus directly: Davis is quoted saying the 2026 midterms may also play a large role in how developments on the court play out over the remainder of Trump's second term, since the Senate confirms justices by a simple majority vote and if Republicans were to lose control of that chamber, it could significantly change the calculus for Alito and Thomas — and separately in the full piece, Davis states that if they wanted to retire, "they'd want to get it rolling before the election," which argues for an announcement clustering in the fall/winter of 2026, squarely inside this market's window. - [2026-04-16] CNN's structural historical pattern strengthens the case: the last seven justices to retire (as opposed to dying in office) have done so when the party more aligned with them controlled both the presidency and the Senate — and could confirm a like-minded replacement . That condition (GOP controls both chambers and the White House) is satisfied right now but may not persist past January 2027, giving Thomas a closing, not open-ended, strategic window that falls inside the contract's life. - [2026-10-04] Direct comparison to Alito's own evolving position shows how quickly "no plans" can shift to active consideration: CNBC reported Alito's status as one of the court's most conservative justices has sparked speculation that he would retire ahead of the midterms — a decision the justice ultimately has not made , and separately Alito told interviewers he had "thought about" retiring this year — demonstrating that even justices who deny retirement plans one month can be reported as actively weighing it the next, undercutting the assumption that Thomas's past denials are durable through mid-2027. - [2026-10-06] Daily Caller's framing that speculation over the possible retirements of Thomas and Alito comes after Trump himself suggested in a Fox News interview that he already has a list of potential Supreme Court appointees and intends to put as many as three new justices on the bench before the end of his term (dated April 2026 interview, still cited in October coverage) shows sustained, not fading, White House-level pressure and preparedness to move fast once any vacancy is signaled, meaning any Thomas announcement could be acted on (and resolve the market) quickly. - [Base case/mechanism] Because the resolution criteria count only the announcement (not the effective date), Thomas does not need to leave the bench mid-term to trigger YES — a traditional "I will retire effective at the end of this term" announcement made any time before July 1, 2027 (including one timed for a traditional end-of-June-2027 term wrap, which falls exactly on the market's closing date) would resolve YES, giving two distinct trigger windows: a pre-midterm "lock in a successor" announcement (fall 2026) or a customary end-of-term announcement (June 2027). BOTTOM LINE: The strongest case for YES rests on a concrete, named mechanism — Trump/clerk succession dealmaking — combined with a hard strategic deadline (the Nov. 2026 midterms potentially flipping the Senate) that political scientists explicitly say pushes any rational retirement decision to be "rolling" before the election, plus the fact that a customary end-of-June-2027 announcement would also land inside the window; both paths sit inside the market's horizon even though no concrete signal has yet emerged. NOT FOUND: No on-the-record statement from Thomas himself addressing 2026-2027 retirement plans; no confirmed negotiation or clerk-successor deal; no post-midterm (November 2026) reporting yet available (future-dated relative to today).
report: no case
YES means: Clarence Thomas publicly announces or officially communicates his retirement/resignation/departure as a Supreme Court justice at any point between now (Oct 6, 2026) and July 1, 2027, regardless of when that departure takes effect. - [2026-10-08] University of Pennsylvania Carey Law confirmed that alumnus Lavi Ben Dor will clerk for Justice Clarence Thomas in OT’27 , a Supreme Court term that begins in October 2027 — three months after this market's closing date, implying Thomas is actively staffing chambers well past the deadline. - [2025-05-23] Legal-industry tracker David Lat (Original Jurisdiction), who has closely tracked clerk hiring as a leading indicator for past retirements, reported that as of mid-2025 three justices—Justices Thomas, Kavanaugh, and Barrett—have hired at least one clerk for OT 2027 , and specifically that Thomas had hired four clerks for OT 2025 ... plus an additional six (6!) clerks for the Terms after that — a volume of forward hiring inconsistent with an imminent mid-term resignation. - [2025-05-23] Lat explicitly used this hiring pattern to bet against retirement, titling his analysis "Will Justices Thomas or Alito retire under Trump? I'm betting against it." , noting the same clerk-hiring signal foreshadowed the retirements of Justices O'Connor, Souter, and Stevens... while it isn't a foolproof indicator , cutting against a near-term announcement. - [2026-05-04] AP reported that upon Thomas reaching the milestone of second-longest-serving justice, John Yoo (a former Thomas clerk) observed "I think he's more energized and excited now than when I first met him," and the article concluded there's no sign he plans to retire anytime soon . - [2026-05-10] Multiple outlets (AOL/Newsweek syndication) reported the specific date Thomas would need to stay to break the all-time tenure record: if he remains on the bench until May 20, 2028, he will surpass the late Justice William O. Douglas, whose tenure of 36 years and 209 days remains the longest in Supreme Court history — a milestone roughly ten months after this market's July 1, 2027 close, giving Thomas a strong personal incentive to stay in his seat through and beyond the deadline. - [2026-10-06] A legal-commentary piece (XIRA) on Judge James Ho's judicial prospects argued Thomas seems to have decided to stake everything on passing William O. Douglas as the longest-serving justice in history on May 20, 2028. Retiring the next day would leave an opening three months deeper into a presidential election year , reinforcing that informed court-watchers expect any Thomas departure, if it comes, to be timed to occur well after mid-2028 rather than before July 2027. - [2026-04-21] Legal scholar Ilya Shapiro noted Thomas is approaching the record and has previously indicated he intends to serve until forced out, cautioning that absent direct confirmation from Thomas or his wife, retirement talk should be heavily discounted (per the April 21 Washington Stand report already in colleagues' files). - Base-rate mechanics: even if Thomas eventually retires, the resolution requires an announcement specifically before July 1, 2027 (about 9 months from today); his own forward clerk commitments into OT'27 functionally rule out an announcement with an effective date before that term unless he breaks a very unusual pattern (per Lat, only Kennedy has "hired a full complement of clerks, then peaced out," per the May 23, 2025 report), and even that precedent still involved years, not months, of lead time. - No on-the-record statement from Thomas or his office addressing retirement has surfaced in 2026; all reporting continues to rely on unnamed "sources close to" him denying near-term plans, and his court workload (oral arguments scheduled into the OT2026 term) shows zero logistical preparation for a mid-term departure. BOTTOM LINE: The strongest NO case rests on a concrete mechanism — Thomas has already hired law clerks for October Term 2027, a term starting after this market's deadline — combined with his evident personal ambition to break the all-time tenure record on May 20, 2028 (a date well past July 1, 2027), making a retirement announcement before the deadline inconsistent with his observable staffing and milestone-chasing behavior. NOT FOUND: No on-the-record statement from Thomas himself in 2026 confirming retirement timing (only clerk-hiring behavior and third-party "sources close to him" denials); no evidence of any health event or incapacitation that would force an earlier-than-planned departure; could not independently verify the exact number or names of all OT'27 Thomas clerks beyond the two identified (Lavi Ben Dor, Dan Vitagliano, Tiffany Bates).

(0) Resolution check: neither the Supreme Court press-release page nor any October 2026 reporting (Bloomberg Law, CNBC, Reuters, Daily Caller) shows a Thomas departure announcement, so nothing has resolved. (a) About 8.8 months remain until the July 1, 2027 deadline, covering the full October Term 2026, which ends in late June. (b) If nothing changes, the answer is No. Thomas is hearing a full docket, has hired clerks for OT'27 (after the deadline), and is plausibly chasing the all-time tenure record on May 20, 2028. People close to him told CBS and ABC in April that he would not retire. (c) NO scenario: he serves through the term without comment and aims for the 2028 record, or a death in office resolves at Kalshi's 'last fair price' rather than as a Yes. (d) YES scenario: a post-midterm scare over Senate control, a negotiated clerk succession with Trump, or a health issue prompts an announcement. Most likely this would be a customary end-of-term notice in spring or June 2027, which still counts because only the announcement date matters. Kennedy's 2018 exit shows that forward clerk hiring is not decisive. The anchors are Kalshi at 14% (bid/ask 12/13) and Polymarket at 14.5% on the same question, two crowds that agree. I shade slightly lower because of the OT'27 clerk hiring, the tenure-record incentive, and Alito's on-record plan to stay through this term, which removes some of the co-retirement pressure.

(0) Nothing shows the condition met. The Supreme Court press-release page lists no Thomas departure, and October 2026 reporting from CNBC, Bloomberg, Reuters and NBC says he has shown no signs of stepping down. He is hearing the new term's docket. (a) About 9 months remain, until July 1, 2027, which covers the full October Term 2026 including the customary end-of-June announcement window. (b) If nothing changes, Thomas stays on and the market resolves No. (c) No scenario: he keeps working through OT2026, having already hired clerks for OT2027 (per Penn Law and David Lat's tracking). He stays aimed at passing William O. Douglas's tenure record on May 20, 2028, so no announcement comes before July 2027. (d) Yes scenario: Democrats win the Senate in November 2026, creating a lame-duck urgency window, or Trump offers a negotiated succession, for example a Thomas former clerk. Thomas then announces a retirement effective at the end of the term, or a health issue prompts an early exit. A death in office settles at last fair price rather than Yes, so it adds little to the Yes side. The anchor is Kalshi at about 13-14%, with Polymarket's identical question at 14.5% as an independent crowd. I shade slightly lower because the OT2027 clerk hiring and the record-chasing incentive are concrete counter-signals, and because Alito's on-record pledge to stay this term lowers the chance of a coordinated pair of retirements. The midterm outcome is the main unpriced uncertainty that keeps this from going lower.

I retain Kalshi's reported 14% YES anchor, corroborated by Polymarket's matching-deadline retirement contract at 14.5%, because the research reveals no clearly unpriced development. No qualifying announcement is documented: the Supreme Court release-list read stops at July 1, 2026, limiting its evidentiary value, but October 3 Reuters and October 6 Bloomberg reporting also indicate no announced retirement plans. Approximately 268 days remain before July 1, 2027; a qualifying public announcement or official communication must occur before that deadline, regardless of the effective departure date, and unchanged circumstances produce NO. A plausible NO scenario is continued service through June 2027, consistent with CBS's April 17 reporting of no 2026 retirement plans and David Lat's May 2025 reporting of advance clerk hiring, although neither establishes Thomas's intentions for 2027. I exclude the October 8 clerk report as future-dated and discount the speculative May 2028 tenure-record ambition; importantly, future staffing does not prevent an earlier retirement announcement. A plausible YES scenario is a negotiated ideological successor prompting an announcement before the current Republican-controlled Senate's term ends in January 2027, or a spring/end-of-June announcement if Republicans retain control. Thomas's age of 78 and historically favorable aligned-party retirement incentives support a meaningful YES probability, but no verified succession negotiations, relevant health deterioration, or direct statement from Thomas justify departing from the market consensus. The stale official-source read leaves some risk of an unobserved qualifying communication, while death in office must not be counted automatically as YES because the rules permit discretionary last-fair-price settlement.

I retain Kalshi's 14% YES anchor, corroborated by Polymarket's same-deadline retirement-announcement market at 14.5%, because the research reveals no clearly unpriced catalyst. No qualifying announcement is documented: the official Supreme Court press-release read stops at July 1, 2026, leaving verification risk, but October 3 Reuters and October 6 Bloomberg reporting also show no retirement signal. Approximately 268 days remain until the deadline; if nothing changes and no permanent departure is publicly announced or officially communicated, No wins. The NO scenario is continued service, supported by CBS's April 17 reporting of no 2026 retirement plans and the May 2025 forward clerk-hiring report, although the suggested May 2028 tenure-record ambition is speculation rather than a commitment. I exclude the future-dated October 8 clerk report, and neither forward hiring nor a desire to serve through 2028 precludes an earlier announcement with a later effective departure date. The YES scenario is a changed personal or health calculus, or assurances about a like-minded successor, producing an announcement before the current Republican Senate's guaranteed window ends in January or during the term ending June 2027. The retained 14% probability accommodates those possibilities, the official-source coverage gap, and the important limitation that anonymous denials concerning 2026 do not establish intentions for 2027. Death in office is not treated as an automatic YES because the rules instead permit discretionary last-fair-price settlement.

(0) The condition is not already met: the Supreme Court press-release page shows no Thomas departure announcement through July 1, 2026, while October reporting also says no announcement has occurred; a public or official announcement must still happen before July 1, 2027. (a) Approximately 268 days, or just under nine months, remain. Kalshi's 14% YES price is the primary anchor, independently corroborated by Polymarket's closely matching 14.5% market. (b) If nothing changes, Thomas remains an active justice and the market resolves No. (c) The clearest No scenario is that Thomas completes the current term, retains clerks hired for October Term 2027, and stays toward the May 2028 longevity record, consistent with Bloomberg, Reuters, CBS, and AP reporting that he has shown no intention of stepping down. (d) A Yes scenario is a strategically timed retirement announcement while Republicans can confirm a successor, potentially following a succession agreement involving a former Thomas clerk or at the June 2027 end of term. I price slightly below Kalshi because the full docket, forward clerk hiring, and repeated sourced denials reinforce No, while excluding the October 8 UPenn item because it postdates today's October 6 forecast date. The lack of a direct statement from Thomas and the possibility that political incentives or health circumstances change prevent a larger move away from the market consensus.
4. Final plain mean of 5 draws
13% (67% confidence)
Yes: 13% No: 87%
Mean of 5 draws (0.11, 0.11, 0.14, 0.14, 0.13). (0) Resolution check: neither the Supreme Court press-release page nor any October 2026 reporting (Bloomberg Law, CNBC, Reuters, Daily Caller) shows a Thomas departure announcement, so nothing has resolved. (a) About 8.8 months remain until the July 1, 2027 deadline, covering the full October Term 2026, which ends in late June. (b) If nothing changes, the answer is No. Thomas is hearing a full docket, has hired clerks for OT'27 (after the deadline), and is plausibly chasing the all-time tenure record on May 20, 2028. People close to him told CBS and ABC in April that he would not retire. (c) NO scenario: he serves through the term without comment and aims for the 2028 record, or a death in office resolves at Kalshi's 'last fair price' rather than as a Yes. (d) YES scenario: a post-midterm scare over Senate control, a negotiated clerk succession with Trump, or a health issue prompts an announcement. Most likely this would be a customary end-of-term notice in spring or June 2027, which still counts because only the announcement date matters. Kennedy's 2018 exit shows that forward clerk hiring is not decisive. The anchors are Kalshi at 14% (bid/ask 12/13) and Polymarket at 14.5% on the same question, two crowds that agree. I shade slightly lower because of the OT'27 clerk hiring, the tenure-record incentive, and Alito's on-record plan to stay through this term, which removes some of the co-retirement pressure.
