Mean of 5 draws (0.16, 0.14, 0.19, 0.19, 0.18). (0) The resolving condition is not met. The STF portal was unreachable (HTTP 403), but reporting from Oct 8–9, 2026 shows Moraes still active: he issued Eduardo Bolsonaro's arrest warrant and met the Federal Police director-general. (a) About 82 days remain before Jan 1, 2027. (b) If nothing changes, he stays. Impeachment needs Senate President Alcolumbre to open a petition, and he has refused all 66+ of them. STF impeachments have a 0% historical success rate. The PL and senators-elect are explicitly targeting impeachment 'in 2027', after the new Senate is seated in February. (c) NO: Dino's pedido de vista on the Vorcaro investigation drags into December or 2027. Even if an investigation opens, the result is at most a suspension, which does not count. Moraes, characteristically combative, rides out the pressure past year-end. (d) YES: Flávio Bolsonaro wins the Oct 25 runoff and a negotiated 'honorable exit' emerges, with back-channels to Gilmar Mendes and Zanin already reported. Moraes would also have an incentive to resign before Lula leaves office on Jan 1, so Lula, not Flávio, picks his successor and the current Senate confirms. That timing argument is the strongest YES case and keeps this from being negligible. Still, there is no confirmed resignation signal, and the pressure campaign's own timeline points to 2027. Kalshi is at 22% (bid 19%/ask 24%) and Polymarket at 19–23.5%; I shade modestly below that given the structural blockers.

Planner reasoning
This is a Kalshi question, so kalshi_direct is the price anchor, and resolution_source should check the STF's official roster. Cross-venue prices from kalshi_related and polymarket_related give independent crowd signals. Wikipedia covers background (de Moraes was born in 1968, so mandatory retirement at 75 is far off), and gdelt_news picks up Brazilian-language headlines on impeachment or resignation moves.

Research loops, bottom lines
- current state: As of October 10, 2026, Moraes remains an active, sitting Supreme Court justice, actively issuing rulings (e.g., Eduardo Bolsonaro's arrest warrant) and attending plenary sessions; dozens of impeachment petitions and one stalled internal STF investigation attempt exist, but no formal removal, suspension, resignation, or retirement process is underway, and the political faction pushing hardest for his ouster explicitly targets action "in 2027" — after the question's Jan 1, 2027 deadline — conting
- base rate: The reference class (impeachment attempts against STF justices, and against Moraes specifically) has a 0% historical success rate across 176+ petitions since 2001 and 134 years of the Court's existence, with the Senate president controlling whether any process even advances; voluntary early resignations do occur among STF justices but historically reflect career transitions or near-retirement timing rather than scandal-driven exits mid-term. This strongly favors "No" as the base-rate expectation
- yes case: The strongest YES path is a voluntary, negotiated "honorable exit" by Moraes — distinct from the slow, historically unsuccessful Senate impeachment track — engineered as part of a broader STF-Bolsonaro camp deal (possibly tied to Jair Bolsonaro's sentence review and Jan 8 amnesty) and catalyzed by the Dino "vista" deadline that forces an internal STF reckoning on investigating Moraes by around December 15, 2026, just before the market's deadline and the Judiciary's year-end recess.
- no case: Every procedural lever that could end Moraes's tenure before Jan 1, 2027 — the STF's own internal Vorcaro probe, and any Senate impeachment process — is either stalled with no resumption date, gated by a Senate president who has explicitly declined to advance it, or deliberately aimed by its proponents at 2027 and beyond; combined with the zero-success historical base rate for STF impeachments and the absence of any resignation signal, the structural and procedural evidence strongly favors NO.

- [2026-10-09] A Rio Times prediction-markets roundup notes

- [2026-10-06] CNN Brasil analysis states

- [2026-09-15] STF plenary session on opening a formal investigation into Moraes over the Vorcaro ties was suspended:
the STF suspended the judgment that could decide on opening an investigation against Moraes over his relationship with Daniel Vorcaro... after Justice Flávio Dino requested more time to review
, with the court split 4-3 on keeping his case separate from colleague André Mendonça's. https://www.infomoney.com.br/politica/ao-vivo-stf-investigacao-alexandre-de-moraes/
- [2026-09-01] Senator Carlos Viana formally

- [2026-10-09] Runoff context:
Flávio Bolsonaro captured 47.03% of valid first-round votes against incumbent President Lula's 45.16%
, setting up an October 25, 2026 runoff that is directly tied to Moraes's political fate, since any Senate removal attempt depends on the post-election Senate composition seated in February 2027. https://www.latintimes.com/brazils-supreme-court-moves-against-eduardo-bolsonaro-four-days-after-his-brothers-historic-600025
BOTTOM LINE: As of October 10, 2026, Moraes remains an active, sitting Supreme Court justice, actively issuing rulings (e.g., Eduardo Bolsonaro's arrest warrant) and attending plenary sessions; dozens of impeachment petitions and one stalled internal STF investigation attempt exist, but no formal removal, suspension, resignation, or retirement process is underway, and the political faction pushing hardest for his ouster explicitly targets action "in 2027" — after the question's Jan 1, 2027 deadline — contingent on a new Senate taking office.
NOT FOUND: No evidence of any binding Senate impeachment trial scheduled before Jan 1, 2027; no STF plenary ruling actually opening a formal investigation/suspension of Moraes (the Sept 15 session was suspended via "pedido de vista" with no new date confirmed in search results); no indication of imminent voluntary resignation or retirement by Moraes (born Dec 1968, below Brazil's mandatory retirement age of 75).
report: base rate
- [2026-09-01] Historical tally:
Moraes has been the target of at least 66 impeachment petitions filed with the Senate over the years, including old filed-away representations and new petitions during the political escalation around the Court
.
At least 66 impeachment requests have been filed against Moraes
. Source: congressoemfoco.com.br.
- [2026-09-01] Base rate of success is zero: the article's own subtitle states that
despite the quantity, the Senate has never approved an impeachment request against an STF minister
. (congressoemfoco.com.br)
- [2025-08-06] Longer historical count:
despite pressure from Bolsonaro allies for the Senate to take up Moraes's impeachment, never in Brazilian republican history has an STF justice been removed by Congress; since 2001 the Senate has received 176 impeachment requests against STF justices, most shelved before formal review, with Moraes leading the ranking with 48 representations against him
. (otempo.com.br)
- [undated, Senate official note] Primary source confirms the procedural base rate:
an impeachment request against an STF justice has never been approved
, and
the Senate president, who must authorize proceedings, has never advanced any such request, and no impeachment process against a Supreme Court justice has ever succeeded
. (senado.leg.br / gazetadopovo.com.br)
- [2026-10-10 approx] Current political momentum has risen sharply but remains gated: a recent article notes
by early this week there were already 66 impeachment requests against Moraes, but Senate President Davi Alcolumbre has not authorized the opening of any of them
. (terra.com.br)
- [2026-10-09] Newly elected senators (taking office 2027) are vocal:
of the 54 senators elected on October 4, 2026, 30 declared themselves favorable to impeachment of STF ministers, representing 55% of the seats contested
, but this reflects the incoming Senate for 2027+, not the sitting body that controls the process through year-end 2026.
- [2026-10-08]
Senator-elect Bia Kicis stated impeachment of Moraes is "priority number one" for the new Senate bloc, alongside amnesty as priority two
— a stated intention/goal, not yet an initiated or advancing process.
- [2026-09-02] Separately, "honorable exit" speculation (voluntary resignation) emerged amid the Banco Master/Vorcaro scandal:
in conversations with politicians since the prior Tuesday, there was growing pressure for Moraes himself to decide to leave the STF
, per CNN Brasil analyst commentary — rumor/pressure, not a confirmed decision.
- [reference class: voluntary early departures] Brazilian STF base rate for *voluntary* early exits (unrelated to scandal) exists but is driven by career moves or age proximity, not political pressure:
Célio Borja left six years three months early in 1992; Nelson Jobim left ten years early in 2006 to run for office; others like Lewandowski, Eros Grau and Celso de Mello left only weeks before mandatory retirement at 75
— none of these precedents involved resignation under political/impeachment pressure while in the midst of a sitting term.
- [reference class: mandatory retirement]
STF justices have life tenure with mandatory retirement at age 75
; Moraes was born in December 1968, so turns 75 only in 2043 — mandatory retirement is irrelevant to this window.
- [structural factor] The Senate presidency is the key gatekeeper, and current leadership (Davi Alcolumbre) has shown no inclination to advance any petition; this gatekeeping pattern has held consistently for 134+ years regardless of the volume of petitions filed.
BOTTOM LINE: The reference class (impeachment attempts against STF justices, and against Moraes specifically) has a 0% historical success rate across 176+ petitions since 2001 and 134 years of the Court's existence, with the Senate president controlling whether any process even advances; voluntary early resignations do occur among STF justices but historically reflect career transitions or near-retirement timing rather than scandal-driven exits mid-term. This strongly favors "No" as the base-rate expectation, though the unprecedented volume of pressure (66+ petitions, scandal-driven "honorable exit" talk, and an incoming more hostile Senate) represents a modest departure from the pure historical pattern.
NOT FOUND: No evidence of any scheduled Senate floor vote or admissibility ruling on a Moraes impeachment petition; no confirmed resignation announcement or date from Moraes himself; no polling data quantifying public/elite probability estimates for his departure.
report: yes case
YES means: Alexandre de Moraes has an actual, confirmed departure date (resignation, removal, retirement, or other permanent exit) and formally vacates his STF seat on or before December 31, 2026 — a temporary suspension or recusal would not count.
- [2026-10-06] A wing within the STF itself, per CNN Brasil's Jussara Soares, is already signaling willingness to negotiate:
"Já há um grupo dentro do Supremo Tribunal Federal que defende buscar um diálogo com uma ala dentro do bolsonarismo."
https://www.cnnbrasil.com.br/eleicoes/ala-do-stf-quer-dialogo-em-meio-a-ameaca-de-impeachment/
- [2026-10-06] Crucially, the same report says the dividing line in any such deal is explicit:
the continued presence of Alexandre de Moraes "seria algo que o novo Congresso e Flávio Bolsonaro (PL-RJ), caso eleito, não estariam dispostos a negociar"
— i.e., any negotiated institutional "peace" is reported as contingent on Moraes specifically leaving, not merely being sidelined. https://www.cnnbrasil.com.br/eleicoes/ala-do-stf-quer-dialogo-em-meio-a-ameaca-de-impeachment/
- [2026-10-06] Rogério Marinho, Flávio Bolsonaro's campaign coordinator, has already made direct contact with senior STF figures:
"o coordenador da campanha de Flávio Bolsonaro, Rogério Marinho (PL), procurou o decano da Corte, Gilmar Mendes, e também o ministro Cristiano Zanin, enviando recados sobre a disposição ao diálogo."
This shows an active back-channel, not just public rhetoric, aimed at resolving the Moraes question. https://www.cnnbrasil.com.br/eleicoes/ala-do-stf-quer-dialogo-em-meio-a-ameaca-de-impeachment/
- [2026-10-06] The PL's own internal vote count has moved further than previously known: the party claims
"já há pelo menos 49 votos garantidos no Senado para o impeachment de Moraes, faltando apenas mais 5 para atingir o mínimo de 54 votos necessários"
— only five votes short, a tally that did not exist in earlier September reporting of dozens of unscheduled petitions. https://www.cnnbrasil.com.br/eleicoes/ala-do-stf-quer-dialogo-em-meio-a-ameaca-de-impeachment/
- [2026-10-06] The PL's stated preferred mechanism is for the Court to force Moraes out itself:
"A preferência do PL seria que o próprio STF resolvesse a questão de Moraes — por meio da abertura de uma investigação relacionada à sua ligação com Daniel Vorcaro, o que resultaria em seu afastamento enquanto durassem as apurações."
While this would be a suspension (not disqualifying under the rules), it is explicitly framed by its proponents as a stepping stone toward full removal, and the same pressure campaign simultaneously pushes for a negotiated resignation as an "honorable exit." https://www.cnnbrasil.com.br/eleicoes/ala-do-stf-quer-dialogo-em-meio-a-ameaca-de-impeachment/
- [2026-09-16] The internal STF timeline creates a concrete window before the deadline: Flávio Dino's "pedido de vista" on the Vorcaro investigation question
has until 90 days to return the case to the plenary; if he uses the full term, the analysis would only be freed up on December 15, four days before the Judiciary's recess.
This means a plenary ruling on whether to formally investigate (and potentially suspend) Moraes could plausibly occur between mid-November and December 15, 2026 — squarely inside the market's window — intensifying pressure for a voluntary "honorable exit" before any formal Senate process even starts.
- [2026-09-25] Dino has discretion to accelerate or delay this timeline for political reasons: reporting noted
the regimental deadline would let Dino return the case before December, but according to reports published that Friday, the possibility being considered by the minister was to leave the discussion for after the second round of the elections
— meaning a resumption and ruling as early as late October/November, materially before Dec 31, remains live. https://www.enfoquems.com.br/dino-avalia-deixar-para-depois-do-2o-turno-julgamento-sobre-caso-moraes-no-stf/
- [2026-10-07] PoderData/Aya polling cited by CNN Brasil shows Flávio Bolsonaro leading the runoff 53%-47% over Lula, which — if the trend holds through the October 25 runoff — would mean a Bolsonaro-aligned president-elect is already confirmed well before January 1, 2027, sharply raising the political cost for Moraes and any STF colleagues of inaction, and strengthening incentives for an early negotiated resignation to pre-empt a hostile 2027 Senate. https://www.cnnbrasil.com.br/eleicoes/ala-do-stf-quer-dialogo-em-meio-a-ameaca-de-impeachment/
- [2026-09-03] Independent of the Senate track, CNN Brasil's own political analysts have floated that
"integrantes do meio político avaliam que uma renúncia voluntária de Moraes poderia funcionar como uma espécie de 'saída honrosa' diante do desgaste provocado pelas revelações envolvendo o ministro e Vorcaro,"
showing the resignation option is being actively discussed in Brasília's corridors, not dismissed as fringe speculation. https://spdiario.com.br/noticias/politica/pressao-por-saida-de-moraes-cresce-nos-bastidores-em-meio-a-crise-no-stf.html
- [2026-10-07] Grassroots PL-aligned sentiment reflects impatience with any deal that doesn't include Moraes leaving before year-end: one widely engaged comment captured in media monitoring insisted "Pacificação PRECISA da saída de no MÍNIMO Moraes e Dino... vão ser minoria logo logo, e senado já tem bancada suficiente pra impeachment," illustrating the political base actively expects an imminent departure, not a 2027-only process. https://quenty.com.br/resumo/7-outubro-2026/pl-rejeita-acordo-amplo-com-o-stf-e-mantem-pressao-sobre-moraes-e-dino
BOTTOM LINE: The strongest YES path is a voluntary, negotiated "honorable exit" by Moraes — distinct from the slow, historically unsuccessful Senate impeachment track — engineered as part of a broader STF-Bolsonaro camp deal (possibly tied to Jair Bolsonaro's sentence review and Jan 8 amnesty) and catalyzed by the Dino "vista" deadline that forces an internal STF reckoning on investigating Moraes by around December 15, 2026, just before the market's deadline and the Judiciary's year-end recess.
NOT FOUND: No confirmed date or commitment from Moraes or any STF/political actor for an actual resignation; no evidence the October 6 "diálogo" contacts have produced a concrete exit agreement; no outcome yet of the October 25 presidential runoff.
report: no case
YES means: Moraes has an actual, confirmed departure date before Jan 1, 2027 — a permanent cessation of his STF seat via resignation, Senate-approved impeachment, removal, or other mechanism — not merely suspension, recusal, or an investigation being opened.
- [2026-09-16] The STF's own internal probe into Moraes (the predicate many hope leads to his removal) is stalled procedurally, not advancing toward any removal:
the STF ended its Sept 15 session without a set date to resume the judgment that could open an investigation against Moraes, after Flávio Dino requested up to 90 days to review the case
.
Even if Dino returns the case early, it falls to the STF presidency to schedule a new date, and the 90-day window does not mean the judgment automatically resumes on day 90.
- [2026-09-16] This is explicitly an investigation-opening vote, several steps removed from any removal power, and could slip past year-end:
new requests for review could again postpone the analysis, pushing it into next year.
Moreover the STF has not even reached the merits:
the STF still has not decided whether Moraes will be investigated.
- [2026-09-01] The constitutionally mandated Senate impeachment gatekeeper remains the decisive bottleneck and has shown no sign of yielding:
Pressured to advance Moraes's impeachment, Senate President Davi Alcolumbre signaled he would not proceed in the coming days, deflecting when asked his decision and stating only that there are 109 requests.
- [2026-09-01] The formal process has many sequential steps even after filing, none of which have begun:
after a complaint is filed, the Senate president must send the request to the Chamber's legal counsel; after technical review, the proposal is analyzed by the Directing Committee, and only then can it be brought to the floor.
None of these stages have started.
- [2026-08-06] A key pragmatic Bolsonaro-aligned power broker, Senate PP leader Ciro Nogueira, has refused to even sign a petition, saying
"Não vou assinar porque é uma pauta impossível. Não temos os 54 votos necessários para aprovar... Não perco tempo com pautas que não têm chance de sucesso."
- [2026-08-06] Nogueira further noted Alcolumbre's personal discretion is dispositive regardless of signature count:
"Eu conheço o presidente da Casa, o presidente Davi Alcolumbre. Pode chegar com 80 assinaturas que ele não abre [o processo], porque essa é uma prerrogativa dele."
- [legal/structural] Primary-source legal analysis confirms there is no deadline forcing the Senate president's hand:
in practice there is no peremptory deadline obliging the Senate president to schedule the receipt or rejection of the complaint immediately, a gap that allows the exercise of the so-called "poder de gaveta" (drawer power), where requests sit pending political convenience.
- [legal/structural] Even if a process somehow opened, the law provides no fixed timeline for ministers (unlike for the president):
Law 1079/50 sets no specific deadline for concluding proceedings against STF ministers, unlike the 180-day limit for the President, leaving the Senate discretion over the timetable.
A full trial, defense, evidence-gathering and a two-thirds floor vote would be needed before removal — a multi-month-minimum process that has not even begun.
- [2026-10-09] The faction most invested in ousting Moraes is itself targeting 2027, after the resolution deadline: this is consistent with Bia Kicis's Oct 9 statement that impeachment is her top priority "a partir de 2027," confirming organized pressure is explicitly aimed at the next Senate (sworn in February 2027), not the current one.
- [status quo] Moraes continues performing active judicial functions through early October 2026 (issuing arrest warrants, meeting with the PF director), with no indication of health issues, resignation talk translating into action, or any scheduled Senate vote.
BOTTOM LINE: Every procedural lever that could end Moraes's tenure before Jan 1, 2027 — the STF's own internal Vorcaro probe, and any Senate impeachment process — is either stalled with no resumption date, gated by a Senate president who has explicitly declined to advance it, or deliberately aimed by its proponents at 2027 and beyond; combined with the zero-success historical base rate for STF impeachments and the absence of any resignation signal, the structural and procedural evidence strongly favors NO.
NOT FOUND: No scheduled date for STF to resume the Vorcaro investigation vote (pending until Dino returns the file, within 90 days of mid-September); no Senate floor vote scheduled on any Moraes impeachment petition; no confirmed resignation plan or date from Moraes.

(0) The resolving condition is not met. The STF portal was unreachable (HTTP 403), but reporting from Oct 8–9, 2026 shows Moraes still active: he issued Eduardo Bolsonaro's arrest warrant and met the Federal Police director-general. (a) About 82 days remain before Jan 1, 2027. (b) If nothing changes, he stays. Impeachment needs Senate President Alcolumbre to open a petition, and he has refused all 66+ of them. STF impeachments have a 0% historical success rate. The PL and senators-elect are explicitly targeting impeachment 'in 2027', after the new Senate is seated in February. (c) NO: Dino's pedido de vista on the Vorcaro investigation drags into December or 2027. Even if an investigation opens, the result is at most a suspension, which does not count. Moraes, characteristically combative, rides out the pressure past year-end. (d) YES: Flávio Bolsonaro wins the Oct 25 runoff and a negotiated 'honorable exit' emerges, with back-channels to Gilmar Mendes and Zanin already reported. Moraes would also have an incentive to resign before Lula leaves office on Jan 1, so Lula, not Flávio, picks his successor and the current Senate confirms. That timing argument is the strongest YES case and keeps this from being negligible. Still, there is no confirmed resignation signal, and the pressure campaign's own timeline points to 2027. Kalshi is at 22% (bid 19%/ask 24%) and Polymarket at 19–23.5%; I shade modestly below that given the structural blockers.

(0) The resolving condition has not been met. As of Oct 8-9, 2026, Moraes is still issuing rulings, including the Eduardo Bolsonaro arrest warrant, and meeting the Federal Police chief, and Rio Times reports both markets still open on Oct 9. The STF site read failed (HTTP 403), but multiple dated news sources confirm he remains on the court. (a) About 82 days remain before Jan 1, 2027, and the Judiciary's year-end recess starts around Dec 19. (b) The status quo is No: he stays, absent a resignation or removal. Impeachment cannot finish in this window. Senate President Alcolumbre has not opened any of the 66+ petitions, no STF justice has ever been removed, and the PL itself targets impeachment for 2027 with the new Senate. The internal STF Vorcaro probe is stalled on Dino's 90-day review request, and at most it could produce a suspension, which does not count. (c) NO scenario: Moraes stays combative through the Oct 25 runoff and the December plenary, and the fight moves to the 2027 Senate. Even a Flávio Bolsonaro win mainly sets up a 2027 impeachment push, not a 2026 exit. (d) YES scenario: Flávio wins the runoff, the STF wing seeking dialogue brokers an 'honorable exit' tied to institutional peace, and possibly a damaging Vorcaro investigation vote in late November or December prompts Moraes to resign before year-end. Market anchor: Kalshi is at 22% and Polymarket at 23.5%, down sharply from a 44% peak. The only live path is a voluntary resignation, and there is no concrete signal of one; Moraes has historically dug in under pressure. I therefore shade below the market to about 14%, keeping meaningful weight on a post-runoff negotiated exit.

I anchor on Kalshi’s live 22% YES price, with the apparently matching Polymarket contract at 23.5% providing corroborating crowd evidence. The condition is neither documented as met nor impossible: CNN Brasil’s October 7–8 reporting describes Moraes continuing to work at the STF, and no source establishes a permanent departure. About 83 days remain until January 1, 2027, and YES requires him actually to vacate the seat permanently before then; an investigation, temporary suspension, or announcement of a later departure does not qualify. If nothing changes, NO wins, and mandatory retirement is not due until 2043. A plausible NO scenario is continued Senate gatekeeping and delayed internal proceedings, consistent with the absence of an advancing impeachment case and the historical lack of successful STF impeachments. The strongest YES scenario is a negotiated resignation following a Bolsonaro runoff victory and renewed Vorcaro-related pressure, supported by CNN Brasil’s October 6 reporting of back-channel contacts but not by any confirmed exit agreement. My modest reduction to 19% reflects a potentially underweighted deadline mismatch: opponents explicitly target the incoming Senate seated in February 2027, while Dino’s late-2026 review deadline guarantees neither a ruling nor a qualifying departure. The official STF roster returned HTTP 403, so direct resolution-source verification remains unavailable; that gap and uncertainty around private negotiations limit confidence and argue against pricing NO near certainty.

I anchor on Kalshi’s live 22% YES price, with the apparently matching Polymarket question at 23.5% providing independent crowd corroboration. No source documents a qualifying departure, and October 8 reporting describes Moraes exercising judicial functions; however, the official STF roster returned HTTP 403, leaving residual verification and source-update risk. Approximately 83 days remain from October 10 until January 1, 2027, and YES requires an actual permanent vacancy before that deadline—not merely a departure announcement, suspension, or recusal. The status quo resolves NO, and a straightforward NO scenario is continued Senate gatekeeping and delayed court proceedings, consistent with the historically unsuccessful record of STF impeachment attempts. My modest downward adjustment to 19% reflects potentially underweighted timing constraints: CNN Brasil’s October 6–7 reporting targets impeachment in 2027, while the newly elected Senate takes office only in February. Furthermore, the reported mid-December deadline for returning the internal investigation case does not guarantee a hearing, much less permanent removal. YES most plausibly occurs through a negotiated resignation following a Bolsonaro runoff victory and renewed scandal pressure, supported by CNN Brasil’s October 6 reporting of institutional backchannels, with Moraes actually vacating his seat before year-end. Those talks have produced no documented resignation agreement or departure date, but they preserve a meaningful early-exit risk despite the procedural obstacles.

(0) The condition has not been met: although the official STF roster was inaccessible due to HTTP 403, CNN Brasil reported Moraes issuing an arrest warrant and meeting the Federal Police director on October 8, confirming he remained an active justice. (a) About 82 days remain until January 1, 2027, and any qualifying departure must be permanent and occur within that short window. (b) If nothing changes, the outcome is No because Moraes remains seated, is far from mandatory retirement, and neither an investigation nor a temporary suspension would qualify. (c) The No scenario is that Senate President Davi Alcolumbre continues blocking the dozens of petitions, the STF investigation vote remains delayed, and removal efforts wait for the incoming Senate in 2027, as proponents themselves have indicated. (d) The Yes scenario is a negotiated voluntary resignation after the October 25 runoff, potentially catalyzed by the STF's Vorcaro deliberations returning by mid-December and back-channel demands that institutional accommodation require Moraes's departure. Kalshi's 22% Yes price is the primary anchor, while the same-question Polymarket price of 23.5% provides an independent crowd estimate. I price Yes modestly below both at 18% because no formal process or resignation commitment exists, impeachment has a zero historical success rate for STF justices, and the organized removal campaign is principally aimed at 2027, while retaining a meaningful tail for an unusually rapid negotiated exit.

(64% confidence)
Yes: 17%
No: 83%
Mean of 5 draws (0.16, 0.14, 0.19, 0.19, 0.18). (0) The resolving condition is not met. The STF portal was unreachable (HTTP 403), but reporting from Oct 8–9, 2026 shows Moraes still active: he issued Eduardo Bolsonaro's arrest warrant and met the Federal Police director-general. (a) About 82 days remain before Jan 1, 2027. (b) If nothing changes, he stays. Impeachment needs Senate President Alcolumbre to open a petition, and he has refused all 66+ of them. STF impeachments have a 0% historical success rate. The PL and senators-elect are explicitly targeting impeachment 'in 2027', after the new Senate is seated in February. (c) NO: Dino's pedido de vista on the Vorcaro investigation drags into December or 2027. Even if an investigation opens, the result is at most a suspension, which does not count. Moraes, characteristically combative, rides out the pressure past year-end. (d) YES: Flávio Bolsonaro wins the Oct 25 runoff and a negotiated 'honorable exit' emerges, with back-channels to Gilmar Mendes and Zanin already reported. Moraes would also have an incentive to resign before Lula leaves office on Jan 1, so Lula, not Flávio, picks his successor and the current Senate confirms. That timing argument is the strongest YES case and keeps this from being negligible. Still, there is no confirmed resignation signal, and the pressure campaign's own timeline points to 2027. Kalshi is at 22% (bid 19%/ask 24%) and Polymarket at 19–23.5%; I shade modestly below that given the structural blockers.
