Mean of 5 draws (0.15, 0.15, 0.18, 0.18, 0.17). (0) No source shows the condition met: as of 2026-10-02/04, Al Jazeera and Nexo confirm Moraes is still a sitting STF justice, and nothing shows a resignation or removal announcement. The STF portal (the resolution source) returned 403, but credible reporting is consistent. (a) About 88 days remain until Dec 31, 2026, and the judicial recess (Dec 20 to Jan 6) eats into that window. (b) The status quo is No. Dino's 90-day vista on the investigation vote expires in December, and court insiders (CNN Brasil) expect no resumption before February 2027. Senate President Alcolumbre has refused to process any of the 66+ impeachment petitions and is waiting on the STF; no justice has ever been impeached and removed. A Flávio Bolsonaro presidency or a new Senate would only take office in 2027, after the deadline. (c) NO: Dino holds the case through the recess, Alcolumbre keeps petitions shelved, Moraes rides out the scandal as he has told allies he will, and the election moves the news cycle on. (d) YES: new Banco Master revelations (the R$131m law-firm contract, Vorcaro's postponed depositions after the election) make his position untenable. That could prompt a resignation announcement, or Fachin could act on Mendonça's afastamento request via a precautionary-removal plenary vote, as the STJ did with Buzzi. This is a real tail given three major papers' editorials and a sitting colleague demanding his removal. The market anchor is 21%, up 6 points this week, likely on election-related speculation. Because the specific procedural evidence pushes both institutional tracks past the deadline, I shade below the market, keeping meaningful weight on a scandal-driven resignation.

This is a Polymarket question, so polymarket_direct is the price anchor and resolution_source is required; the resolution source is official Brazilian government/STF information. Related markets on both venues give a cross-market signal. Wikipedia covers background: Moraes's tenure, the mandatory retirement age of 75 (he was born in 1968, so not close), and US sanctions. GDELT picks up Portuguese-language news on impeachment efforts after the October 2026 elections.

report: current state
- [2026-07-30→2025-12-12] Alexandre de Moraes remains a sitting STF Justice; his only US sanction episode (Global Magnitsky designation imposed 30 July 2025) was lifted on 12 December 2025, and he was never removed from his judicial post as a result. (https://home.treasury.gov/news/press-releases/sb0211, https://public-inspection.federalregister.gov/2026-05753.pdf) - [2026-08-16] The Financial Times reported the US had discussed re-imposing Magnitsky-style sanctions on Moraes, tied to police searches he authorized against a journalist; Reuters confirmed no final decision had been made. US discussed re-imposing sanctions on justice Alexandre de Moraes per FT on 16 Aug 2026, but no decision was taken, and his 2025 listing was lifted. (https://www.riotimesonline.com/us-moraes-sanctions-brazil-magnitsky/) - [2026-09-01] Federal Police of Brazil released as part of the Banco Master case messages and records indicating a close relationship between former banker Daniel Vorcaro and Alexandre de Moraes, including conversations related to investigations into the bank and professional relations with the law firm of Moraes's wife. (https://en.wikipedia.org/wiki/Alexandre_de_Moraes) - [2026-09-01/02] News organizations including O Estado de S. Paulo, O Globo and Folha de S.Paulo published editorials calling for Moraes to leave the Supreme Federal Court, either through resignation, removal by the court's plenary, or impeachment proceedings initiated by the Federal Senate. (https://en.wikipedia.org/wiki/Alexandre_de_Moraes) - [2026-09-03] As of September 3, 2026, 55 new impeachment petitions had been filed with the Federal Senate against the justice. (https://en.wikipedia.org/wiki/Alexandre_de_Moraes) - [2026-09-15] The Supreme Court adjourned without ruling on Justice Alexandre de Moraes's case after Justice Flávio Dino requested a formal review that can freeze the case for up to 90 days; Cármen Lúcia apologized to the nation, saying the court had "generated unrest." Justices Toffoli and Nunes Marques had already recused themselves. (https://www.riotimesonline.com/brazil-supreme-court-moraes-dino-vista-2026/) - [2026-09-16] Dino's vista request allows him to hold the case for up to 90 days, a deadline that extends past both the first round of elections (4 October) and a potential runoff (25 October); Dino can return the case earlier if he chooses. (https://www.metropoles.com/brasil/crise-no-stf-deve-atravessar-eleicoes-sem-resposta-sobre-moraes) - [2026-09-17] Per STF rules, the 90 days run from publication of the session minutes; if Dino does not return the case within that window, it is automatically released to continue the judgment. No fixed resumption date exists yet. (https://www.infomoney.com.br/politica/quando-o-stf-retomara-o-julgamento-de-alexandre-de-moraes-entenda-os-proximos-passos/) - [2026-09-28] Rio Times updated its tracker noting Fachin pulled the judgment of Mendonça's conduct from the 23 September agenda and appealed for a truce; the Federal Police paused new Compliance Zero search and arrest requests, and Vorcaro's late-September depositions were postponed until after election day. (https://www.riotimesonline.com/brazil-supreme-court-moraes-dino-vista-2026/) - [2026-09-15] A poll cited in Terra found only 27.8% of respondents say they trust the work and ministers of the STF, while 85% believe some ministers are directly involved in the Master case, versus 66% in March. (https://terra.com.br/noticias/stf-precisa-provar-que-suas-regras-sao-mais-importantes-do-que-seus-onze-ministros,5e66c76314a33ad4236268107eee641f301ewxhr.html) - [2026-10-02] Axios reported that the U.S. revoked his visa and sanctioned him, though the sanctions were later lifted — confirming the sanctions remain lifted as of early October 2026, with no reported new US sanctions or removal action. (https://axios.com/2026/10/02/brazil-election-lula-flavio-bolsonaro-trump-amazon) - [2026-10-02] Al Jazeera reported Moraes is still a sitting Justice, noting he is among the high-profile figures implicated in the Banco Master scandal , with no indication of resignation or removal as of this date. (https://aljazeera.com/features/longform/2026/10/2/how-the-banco-master-scandal-injected-chaos-into-brazils-presidential-race) - [2026-10-04] Brazil's first-round presidential election is taking place today; political reporting (Nexo Jornal) confirms the STF investigation question against Moraes remains unresolved, with the climax of the crisis being a 15 September session to decide whether to open an investigation against Moraes, which ended without resolution after a request for review by Dino. (https://nexojornal.com.br/expresso/2026/10/03/eleicao-2026-explicada-lula-flavio-bolsonaro-presidente-brasil) BOTTOM LINE: As of October 4, 2026, Moraes remains a sitting STF Justice with no resignation, removal, or renewed international sanctions in effect; the internal STF probe into his conduct is formally paused (via Dino's up-to-90-day "vista") and unlikely to be resolved before year-end, while impeachment petitions in the Senate have not advanced to a vote — suggesting no imminent change in his status through the current reporting window. NOT FOUND: No evidence of any Senate impeachment vote scheduled or taken against Moraes; no confirmed compulsory retirement filing (he is not due for mandatory retirement until 2043); no official statement from Moraes himself regarding resignation; no confirmation of exact date Dino's 90-day vista period expires (depends on publication of session minutes, not independently found).
report: base rate
- [2026-10-04 reference] [1988–present] Historically, [no Supreme Federal Court justice has ever been removed by Senate impeachment in Brazil's history, and the procedural barriers remain formidable despite a surge in petitions.](https://polymarket.com/event/any-brazil-stf-justice-removed-by-impeachment-before-2027) This is the core outside-view base rate: zero successes across decades of the modern STF, despite many high-profile petitions over the years. - [2026-09-14] The institutional gatekeeping mechanism is decisive: only the Senate president can rule an impeachment request admissible, and without that step there is no committee, no hearing and no floor vote , which explains why "none" of the dozens of petitions against Moraes have ever moved (https://www.riotimesonline.com/moraes-impeachment-requests-senate-count-2026/). - [2026-09-14] Volume of petitions is unusually high but procedurally inert: One tally puts 55 against Moraes since January 2021, another at least 66; Senate President Davi Alcolumbre says 109 requests are pending against the ten justices, and called that abnormal (https://www.riotimesonline.com/moraes-impeachment-requests-senate-count-2026/). - [2026-08-03 retrospective] Even at the peak of Magnitsky-sanctions-driven pressure in 2025, pro-impeachment sentiment fell well short of the required threshold: as of early August, 34 senators support impeachment, 19 reject it, and 28 remain undecided, but removing a Supreme Court judge requires 54 votes—two-thirds of the Senate , and the Senate has never removed a Supreme Court justice in modern times (https://www.riotimesonline.com/ousting-the-greatest-liability-brazils-senate-sees-growing-push-to-impeach-supreme-court-judge-moraes/). - [2022] Precedent from the last acute crisis: President Jair Bolsonaro submitted to the Federal Senate a request to impeach Justice Alexandre de Moraes; the Supreme Federal Court released a statement repudiating the action, and Senate President Rodrigo Pacheco said he saw no technical, legal, or political grounds for the request to move forward — illustrating the pattern of petitions dying at the admissibility stage even from a sitting president (https://en.wikipedia.org/wiki/Timeline_of_the_2022%E2%80%932023_Brazilian_coup_plot). - [2026-09-11 odds] A sibling Polymarket contract asking whether **any** STF justice (not specifically Moraes) is removed via impeachment before 2027 traded at an 8% implied probability with $90,192 volume, reflecting trader skepticism consistent with the historical base rate (https://polymarket.com/event/any-brazil-stf-justice-removed-by-impeachment-before-2027). - [2026-09-29] Resignation is also assessed as highly unlikely by insiders: the Brazilian state-owned news agency Agência Brasil recounted that the controversial Justice has told allies that he is not considering the possibility of early retirement from the Brazilian Supreme Court due to his alleged contact with the arrested banker Daniel Vorcaro (https://www.breitbart.com/latin-america/2026/09/10/brazils-dictator-judge-removed-from-fake-news-inquiry-he-used-to-persecute-conservatives/). - [1890s–2026] Mandatory retirement base rate: there is a mandatory retirement age of 75 for STF justices, but Moraes (born 1961) is roughly 65, so natural/age-based exit is not a live outside-view pathway within this market's window. - [2004–1805 analogy, US context] Cross-national base rate for comparable "lifetime judge" removal attempts: a Supreme Court justice has been impeached — Justice Samuel Chase was impeached by the House of Representatives in 1804 but was acquitted by the Senate in 1805, so he was never removed from office , and since then, no justice has been removed through impeachment — underscoring that even in a different jurisdiction with a lower (simple-majority-initiated) process, successful removal of a top-court justice is essentially a null historical event. - [2026-09-15] Even internal, lower-bar mechanisms (plenary investigation votes within the STF itself, not impeachment) have stalled: Tuesday's Supreme Court session opened to decide whether Justice Alexandre de Moraes should be investigated over his ties to Banco Master, but the bench never reached that question; two justices recused instead, and the vote never happened , showing that process friction extends beyond the Senate to the Court itself (https://www.latintimes.com/brazils-supreme-court-opened-historic-vote-justice-moraes-two-justices-quit-bench-before-vote-599256). BOTTOM LINE: The reference class (STF justice impeachment/removal attempts, including multiple against Moraes himself since 2021, plus the historical US analogy) shows a 0% success rate across many dozens of attempts over decades, with removal blocked by a single-gatekeeper admissibility rule and a 54/81 supermajority threshold rarely approached; the closest sibling market (any-justice impeachment removal) is priced around 8%, well below the specific Moraes contract's reported level, suggesting the base rate alone argues strongly for "No," though the unprecedented volume of petitions and the Banco Master scandal represent a genuine (if still long-shot) tail risk above the pure historical zero. NOT FOUND: No instance of any Brazilian Supreme Federal Court justice ever being formally impeached and removed since the court's 1891 founding or under the 1988 Constitution; no confirmed scheduling of an actual Senate floor vote or admissibility ruling on any Moraes petition as of early October 2026.
report: yes case
YES means: Alexandre de Moraes ceases—even temporarily—to hold his seat as a Justice of Brazil's Supreme Federal Court at any point between market creation (2026-03-09) and 2026-12-31, whether via resignation, plenary-ordered precautionary removal ("afastamento cautelar"), preventive detention, Senate impeachment, or any announcement of same (even if the effective date is later). - [2026-09-03] A fellow sitting Justice, André Mendonça, formally asked STF president Edson Fachin for Moraes's "afastamento imediato" (immediate removal), with the request explicitly slated to later require plenary confirmation — a peer-initiated internal removal push unprecedented among sitting STF colleagues. (https://jornaldebrasilia.com.br/noticias/politica-e-poder/mendonca-pede-a-fachin-afastamento-imediato-de-moraes-do-stf/) - [2026-09-23] Lawyers Paulo Faria and Filipe de Oliveira filed an amended "notícia-crime" reiterating demands for Moraes's precautionary removal and preventive arrest, newly citing a reiterated pedido de afastamento cautelar de Moraes, which they say would be temporary and aimed at preserving evidence and the integrity of the investigation , backed by new specifics: a R$131 million contract between Master and Viviane Barci, payments, and aircraft use . (https://revistaoeste.com/no-ponto/afastamento-de-moraes-stf/) - [2026-02-10] A direct institutional precedent exists for a sitting high-court justice: the STJ's full bench unanimously ordered the precautionary removal of Justice Marco Buzzi amid a disciplinary inquiry, describing the removal as precautionary, temporary and exceptional — showing Brazil's judiciary has a working mechanism and willingness to suspend a sitting top-court magistrate mid-term, which is the exact kind of "any period of time" event this market would count as YES. - [2023-01] Moraes himself set a precedent for STF-ordered interim removal of a sitting official, having ordered the 90-day removal of Federal District governor Ibaneis Rocha, later upheld 6-0 by the full STF bench — demonstrating the Court's comfort invoking "afastamento" as a tool, which campaigners now seek turned against Moraes. - [2026-09] Public pressure for exactly this "any period of time" outcome has broadened beyond jurists: presidential candidate Ronaldo Caiado campaigned on calling for Moraes's afastamento so he could give explanations about the Banco Master messages and million-value contracts , signaling the demand has entered mainstream electoral politics, not just fringe petitions. - [2026-09-29] Street-level pressure continues after the election cycle began, with a Belo Horizonte rally pressuring Senate president Rodrigo Pacheco to schedule Moraes's impeachment request, with banners reading "Fora Moraes" — showing sustained, not fading, momentum into Q4 2026. - [2026-09-?] Separately, a law-interpretation debate undercuts Alcolumbre's personal veto: Gazeta do Povo reported the 1950 Impeachment Law assigns receipt of complaints to the Senate's governing board (Mesa), not to the chamber president individually — a procedural opening that, if successfully invoked by senators like Carlos Viana, could bypass the single-gatekeeper bottleneck that has blocked all past petitions. - [2026-09-23] Viana's formal ethics complaint against Alcolumbre for refusing to process the impeachment requests shows the internal fight over procedure is still live and could force an admissibility ruling before year-end regardless of Alcolumbre's preference. (https://www.gazetadopovo.com.br/republica/viana-pede-afastamento-de-alcolumbre-por-nao-pautar-impeachment-de-moraes/) - [2026-09-01] The scandal driving all these petitions remains unresolved and expanding: Federal Police records of messages between Moraes and Banco Master's Daniel Vorcaro became the catalyst for the editorial boards of three major papers to call for his exit, and new financial details (the R$131m law-firm contract, R$50m aircraft deal) surfaced weeks later, suggesting the evidentiary base is still growing rather than closing out. - [2026-10-04] As of election day, no resolution has occurred, but multiple simultaneous tracks remain open through year-end: the STF's own internal investigation vote (paused via Dino's vista, releasable any time before its ~mid-December deadline), the Senate impeachment logjam (now contested on procedural grounds), and the ad hoc "afastamento cautelar" petitions sitting before Fachin — any one of which reaching even a temporary suspension order before December 31 would trigger YES. BOTTOM LINE: The strongest YES path is not classic impeachment (which has 0% historical success) but a plenary-ordered "afastamento cautelar" — a mechanism with a fresh 2026 institutional precedent (Justice Buzzi at the STJ) and an unprecedented peer-filed request from Justice Mendonça himself plus reiterated private petitions with escalating financial evidence; because the question counts any temporary cessation, this lower-bar internal remedy, not Senate removal, is the most plausible single route to YES before 2026-12-31. NOT FOUND: No evidence Fachin has ruled on Mendonça's afastamento request or the lawyers' September 23 petition; no confirmed STF plenary vote scheduled on any afastamento cautelar against Moraes; no indication Dino has returned the case early or that Fachin has set a resumption date (ministers reportedly expect no resumption before February 2027, which would fall outside this market's window if that path is the only one pursued).
report: no case
YES means: Alexandre de Moraes ceases to be a sitting STF Justice for any period of time (resignation, removal, or an announcement of either) between market creation (2026-03-09) and 2026-12-31 11:59 PM ET. - [2026-09-23] STF insiders cited by CNN Brasil's Tainá Falcão believe the plenary's decision on whether to even investigate Moraes só deverá ser retomado em fevereiro de 2027 — meaning the court's own internal probe will not even resume judgment, let alone impeachment or removal, within the market's 2026 resolution window. - [2026-09-23] The same report details that the 90-day "vista" deadline falls in December, but integrantes da Corte consideram improvável que o processo volte ao plenário antes do recesso do Judiciário, que começa no dia 20 do mesmo mês e se estende até seis de janeiro de 2027 and collective recess for justices runs through end of January — a direct mechanism showing even the internal track structurally cannot conclude before the Dec 31 deadline. - [2026-09-23] Even if Dino returns the case before the recess, resumption is not automatic: mesmo que a vista seja liberada dentro do prazo, a retomada do julgamento depende da inclusão na pauta pelo presidente do Supremo, Edson Fachin — adding a further discretionary chokepoint controlled by the court's own president. - [2026-09-26] A JBrasília report on allied signals indicates Dino himself is in no hurry: o ministro Flávio Dino avalia liberar o julgamento sobre o relatório com as mensagens do ex-banqueiro Daniel Vorcaro a Alexandre de Moraes apenas após o segundo turno , explicitly to keep the court's internal crisis from affecting the election — a stated motive for further delay well into Q4 2026. - [2026-09-01→09-03] On the Senate track, President Alcolumbre has explicitly refused to advance any petition: pressionado pela oposição para dar andamento ao impeachment do ministro do Supremo Tribunal Federal (STF) Alexandre de Moraes, o presidente do Senado, Davi Alcolumbre (União-AP), sinalizou nesta terça-feira (1), que não deve dar andamento ao processo nos próximos dias , and a Senator's formal complaint over this inaction went nowhere: o senador Carlos Viana afirmou que o "prazo acabou" e denunciou Alcolumbre por não abrir processo de impeachment contra Moraes... no entanto, Alcolumbre sinalizou que não dará andamento aos pedidos de impeachment . - [2026-09-02] Legal analysis confirms the Senate President remains the critical gatekeeper despite statutory ambiguity about whether the "Mesa" collectively should decide: o artigo 44 da Lei do Impeachment estabelece que, "recebida a denúncia pela Mesa do Senado", ela será lida na sessão seguinte... Segundo Mariano, o Regimento Interno não estabelece prazo para que o presidente despache o pedido — i.e., there is no deadline forcing Alcolumbre to act, so petitions can sit indefinitely. - [2026-09-04 (reported in later piece)] CNN's own political analyst reported the Senate leadership's real plan is to defer entirely to the STF: aliados próximos ao presidente do Senado, Davi Alcolumbre (União-AP) avaliam que ele não deve dar andamento aos pedidos de impeachment contra Alexandre de Moraes... a tendência... é que o presidente do Senado aguarde uma definição do próprio Supremo para o caso — creating a circular stalemate where neither branch will move first, and the STF's own process is already pushed to 2027. - [2026-09-04] Even Alcolumbre's one signal of flexibility was conditional and non-committal: o presidente do Senado, Davi Alcolumbre (União-AP), sinalizou a senadores que, caso a pressão pela abertura de um processo de impeachment contra o ministro Alexandre de Moraes... se torne insustentável, poderia [proceed]... até o momento, a sinalização não representa a abertura formal de processo de impeachment contra Moraes ou Mendonça . - [2026-09-17 updated] Petition count against Moraes specifically has risen to at least 66 of the 109 total STF petitions per a recent tally, yet volume has not translated into any procedural movement: atualmente, ao menos 66 pedidos de impeachment contra o ministro Alexandre de Moraes já foram apresentados... Alcolumbre apontou a existência de pelo menos 109 pedidos de impeachment de 10 ministros do STF — 66 deles relacionados a Alexandre de Moraes , reinforcing that quantity of filings is decoupled from any actual admissibility step. - [2026-09-29] Grassroots pressure campaigns continue (e.g., a Belo Horizonte rally demanding Senate President Pacheco — note: conflated with Alcolumbre in some coverage — advance impeachment) but remain purely extra-institutional, with no legislative follow-through reported. - [2026-10-04] Al Jazeera and Nexo Jornal reporting from today's first-round election day confirm Moraes remains seated and the STF's own investigation question is "unresolved" with no new date — consistent with the Feb-2027 resumption consensus, meaning both the judicial and legislative pathways to removal are now independently confirmed to extend past the Dec 31, 2026 market deadline. BOTTOM LINE: Two independent, mutually-reinforcing institutional facts argue strongly for NO: (1) the STF's own internal track (Dino's vista plus the December-January judicial recess) is expected by sitting ministers to push resumption to February 2027, after the market's Dec 31, 2026 resolution deadline; and (2) the Senate's impeachment track remains fully gated by Senate President Alcolumbre, who has openly signaled he will not advance any of the 66+ petitions and instead plans to wait on the STF — meaning neither branch's process can plausibly conclude within the trading window, absent an unprecedented sudden resignation. NOT FOUND: No specific calendar date for STF resumption beyond the "February 2027" estimate; no evidence of any Senate Mesa vote, admissibility ruling, or committee action on any Moraes impeachment petition as of October 4, 2026; no statement from Moraes indicating imminent resignation (contrasts with earlier reports he told allies he is not considering early retirement).

(0) No source shows the condition met: as of 2026-10-02/04, Al Jazeera and Nexo confirm Moraes is still a sitting STF justice, and nothing shows a resignation or removal announcement. The STF portal (the resolution source) returned 403, but credible reporting is consistent. (a) About 88 days remain until Dec 31, 2026, and the judicial recess (Dec 20 to Jan 6) eats into that window. (b) The status quo is No. Dino's 90-day vista on the investigation vote expires in December, and court insiders (CNN Brasil) expect no resumption before February 2027. Senate President Alcolumbre has refused to process any of the 66+ impeachment petitions and is waiting on the STF; no justice has ever been impeached and removed. A Flávio Bolsonaro presidency or a new Senate would only take office in 2027, after the deadline. (c) NO: Dino holds the case through the recess, Alcolumbre keeps petitions shelved, Moraes rides out the scandal as he has told allies he will, and the election moves the news cycle on. (d) YES: new Banco Master revelations (the R$131m law-firm contract, Vorcaro's postponed depositions after the election) make his position untenable. That could prompt a resignation announcement, or Fachin could act on Mendonça's afastamento request via a precautionary-removal plenary vote, as the STJ did with Buzzi. This is a real tail given three major papers' editorials and a sitting colleague demanding his removal. The market anchor is 21%, up 6 points this week, likely on election-related speculation. Because the specific procedural evidence pushes both institutional tracks past the deadline, I shade below the market, keeping meaningful weight on a scandal-driven resignation.

(0) Nothing shows the condition already met. As of 2 to 4 October 2026, Al Jazeera, Axios and Nexo all report Moraes still seated, with no resignation or removal announced. The resolution-source fetch failed, but the reporting consensus is clear. (a) About 3 months remain until 31 December 2026, and the judicial recess starting 20 December effectively shortens the window for court action. (b) Status quo is No. Dino's up-to-90-day vista freezes the STF's internal investigation vote, and CNN Brasil sources say ministers expect resumption only in February 2027. Senate President Alcolumbre has openly refused to admit any of the 66+ impeachment petitions and is deferring to the STF. Moraes has told allies he is not considering early retirement. (c) NO scenario: the Lula–Flávio runoff ends, Dino holds the case into December, Fachin does not schedule it before recess, and the Senate stalemate persists into the new legislature in February 2027. (d) YES scenario: post-election Vorcaro depositions or Federal Police releases produce damning new evidence. That could push Fachin to put Mendonça's request for Moraes's immediate removal before the plenary, or push Moraes to resign. Any temporary removal or an announced resignation counts as YES. There is a fresh 2026 precedent: the STJ's precautionary removal of Justice Buzzi. The market sits at 21% (up 6 points this week, range 5.5–37.5%). I shade below it because the research documents structural delays pushing both institutional tracks past the deadline, and because no STF justice has ever been removed by impeachment. I keep a meaningful tail for the expanding scandal and possible post-election political shifts.

No supplied source establishes a qualifying departure or announcement: Al Jazeera (October 2) and Nexo (October 3) describe Moraes as still serving with proceedings unresolved, although the official STF roster could not be checked because access returned HTTP 403. Roughly 89 days remain until December 31, 2026, 11:59 PM ET, and continued tenure without a qualifying departure announcement resolves No. I anchor on Polymarket's live 21% Yes price and adjust modestly to 18%, judging the deadline-specific scheduling barriers and uncertainty over whether suspension actually ends judicial status somewhat underweighted. The principal No scenario is that Dino's review and subsequent scheduling delays carry proceedings beyond year-end—as CNN Brasil reported September 23 that insiders expected February 2027 resumption—while Senate President Alcolumbre continues withholding impeachment action. The strongest Yes scenario is fresh Banco Master evidence breaking institutional resistance after the election, prompting a resignation announcement or qualifying interim removal, with Mendonça's September 3 removal request providing a concrete alternative to Senate impeachment. Delay is not impossibility: Dino can return the case early, the review period reportedly expires around December, and an announced resignation or removal qualifies even if effective later. However, suspension from duties or removal from an individual inquiry does not unambiguously establish that Moraes has ceased to be a Justice, so I discount the YES report's automatic-trigger interpretation and require official information or credible reporting establishing a qualifying change. Confidence is moderate because official verification failed, the scheduling forecast is not binding, and the research contains factual inconsistencies about Moraes's birth year and the Senate presidency.

Polymarket's live 21% YES price is my anchor; I adjust modestly to 18% for potentially underweighted scheduling bottlenecks and uncertainty over whether suspension of duties would satisfy the resolution wording. No supplied source documents a qualifying departure or announcement, and Al Jazeera (October 2) and Nexo (October 3) describe Moraes as still seated, although the official STF roster returned HTTP 403 and could not be verified directly. About 89 days remain until December 31, 2026, at 11:59 PM ET, by which time a qualifying cessation or resignation/removal announcement must occur, even if an announced departure takes effect later. If nothing changes, Moraes retains his seat without announcing departure and NO wins. A concrete NO scenario is that Dino's review and the judicial recess push proceedings into February 2027, as CNN Brasil reportedly anticipated on September 23, while Senate President Alcolumbre continues withholding action on impeachment petitions. A plausible YES scenario is that further Banco Master evidence after the elections prompts a resignation announcement or an officially recognized temporary removal, with Mendonça's September 3 removal request providing a specific institutional pathway beyond impeachment. However, preventive detention, suspension of duties, or removal from an individual inquiry cannot automatically be equated with ceasing to be a Justice; the official action and credible-reporting consensus would determine whether the condition is met. The February timetable is only an insider estimate, Dino can return the case early, and the failed official-source read plus inconsistencies in secondary reporting justify retaining a meaningful YES probability rather than treating delay as guaranteed.

(0) The condition has not already been met: Al Jazeera and Nexo Jornal reported on October 2–4 that Moraes remained a sitting STF Justice, although the official STF page could not be checked because it returned HTTP 403. (a) About 88 days remain until December 31, 2026, during which Moraes would need to resign, be removed or temporarily suspended, or have such an action officially announced. (b) If nothing changes, the market resolves No because Moraes remains seated, the STF proceeding is paused by Flávio Dino's review request, and no Senate impeachment petition has advanced. (c) The central No scenario is continued institutional delay: STF insiders expect reconsideration only in February 2027 because of the review period and judicial recess, while Senate President Davi Alcolumbre continues withholding admissibility and waiting for the STF. (d) A Yes scenario is that new Banco Master evidence prompts Fachin or the STF plenary to order an exceptional precautionary suspension, as requested by André Mendonça, or creates enough pressure for a resignation announcement before year-end. Against Polymarket's 21% Yes anchor, I price Yes modestly lower at 17% because the February timetable, the Senate gatekeeping stalemate, and the historical absence of a successful STF impeachment outweigh the fresh but unscheduled temporary-removal requests.

Yes: 17% No: 83%
Mean of 5 draws (0.15, 0.15, 0.18, 0.18, 0.17). (0) No source shows the condition met: as of 2026-10-02/04, Al Jazeera and Nexo confirm Moraes is still a sitting STF justice, and nothing shows a resignation or removal announcement. The STF portal (the resolution source) returned 403, but credible reporting is consistent. (a) About 88 days remain until Dec 31, 2026, and the judicial recess (Dec 20 to Jan 6) eats into that window. (b) The status quo is No. Dino's 90-day vista on the investigation vote expires in December, and court insiders (CNN Brasil) expect no resumption before February 2027. Senate President Alcolumbre has refused to process any of the 66+ impeachment petitions and is waiting on the STF; no justice has ever been impeached and removed. A Flávio Bolsonaro presidency or a new Senate would only take office in 2027, after the deadline. (c) NO: Dino holds the case through the recess, Alcolumbre keeps petitions shelved, Moraes rides out the scandal as he has told allies he will, and the election moves the news cycle on. (d) YES: new Banco Master revelations (the R$131m law-firm contract, Vorcaro's postponed depositions after the election) make his position untenable. That could prompt a resignation announcement, or Fachin could act on Mendonça's afastamento request via a precautionary-removal plenary vote, as the STJ did with Buzzi. This is a real tail given three major papers' editorials and a sitting colleague demanding his removal. The market anchor is 21%, up 6 points this week, likely on election-related speculation. Because the specific procedural evidence pushes both institutional tracks past the deadline, I shade below the market, keeping meaningful weight on a scandal-driven resignation.
