Mean of 5 draws (0.61, 0.60, 0.60, 0.58, 0.64). (0) Not yet resolved. Five 2026 cuts are confirmed per BCB and secondary sources: March, April, June, August and September, with the Selic now at 13.75%. Reaching 7 requires a cut at both remaining Copom meetings, Nov 3-4 and Dec 8-9. (a) About 2 months remain, with exactly two decisions left before the Jan 1, 2027 close. (b) Status quo, no further moves, leaves 5 cuts and resolves No. The consensus path in the Focus survey, a 13.50% year-end Selic, gives 6 cuts, which is also No. (c) No scenario: Copom cuts in November but pauses in December. Triggers would be the upside September IPCA-15 surprise, inflation expectations still drifting above target, fiscal and election risk, and the committee's explicit refusal to give a 'blank check'. (d) Yes scenario: November delivers cut #6, which markets price at ~91-93% across Polymarket readings. December then also cuts because the Itaipu electricity effect proves transitory, and a market-friendly runoff on Oct 25 eases the risk premium. XP's 13.25% year-end forecast is exactly this path. The Kalshi anchor is 74% and has risen sharply (+33 points in 7 days), perhaps reflecting post-election repricing. However, the independent Polymarket December 25bp contract sits near 48-50%, and the Focus median implies no December cut. Together these suggest roughly 0.92 × ~0.55 ≈ 50%. I blend toward the Kalshi anchor, since its recent move may reflect information my sources lag, and land at about 61%.

Planner reasoning
The Kalshi price is the anchor. Copom meets 8 times a year, so by October 7 several meetings have passed; the remaining ones are likely early November and December. The key fact is how many cuts have happened so far in 2026. FRED's Brazil policy rate series plus the BCB Selic history page give a structured count, and related Kalshi markets for the next Copom decision show what the crowd expects from the remaining meetings.

- [2026-03-18] First 2026 Selic cut: Copom's 277th meeting lowered the rate from 15.00% to 14.75%, beginning the easing cycle (cut #1). https://www.riotimesonline.com/brazil-copom-selic-14-25-percent-third-cut-2026/ - [2026-04-29] Second cut: 278th meeting reduced the Selic to 14.50%, with the meeting held with the Selic at 14.75% — the highest level since July 2006, after the committee cut by 25 basis points in March from 15.00% (cut #2). https://www.bcb.gov.br/en/monetarypolicy/copomstatements - [2026-06-17] Third cut: In its 279th meeting, the Copom decided to lower the Selic rate to 14.25% p.a. (cut #3). https://www.bcb.gov.br/en/pressdetail/2673/nota - [2026-08-05] Fourth cut: Brazil's Copom cut it by 25 basis points on 5 August 2026 in a unanimous vote of the seven-member rate-setting committee , taking the Selic to 14.00% (cut #4). https://www.riotimesonline.com/brazil-copom-selic-14-percent-fourth-cut-2026/ - [2026-09-16] Fifth cut: Brazil's central bank reduced interest rates by 25 basis points to 13.75%, marking the fifth consecutive meeting with a rate cut . https://www.investing.com/news/economy-news/brazil-economists-cut-2026-interest-rate-forecast-to-1350-93CH-4908896 - [2026-10-07] Current Selic stands at 13.75%, confirmed by the central bank's own site showing Last Copom Meeting 09/16/2026, Selic 13.75%, Selic Target . https://www.bcb.gov.br/en - [2026-10-07] Official 2026 Copom calendar confirms only two meetings remain: Copom meets on 3 and 4 November 2026, with the decision announced on 4 November , followed by the final meeting on 8-9 December 2026 (per BCB's published 2026 schedule). https://www.riotimesonline.com/brazils-financial-morning-call-for-wednesday-october-7-2026/ - [2026-10-07] Prediction-market pricing for the November decision: Prediction markets price a quarter-point Selic cut at Copom's 4 November decision at 91% on Polymarket, with 5.5% on no change (cut #6 likely). https://www.riotimesonline.com/brazils-financial-morning-call-for-wednesday-october-7-2026/ - [2026-10-06] The latest Focus survey (Central Bank's weekly poll) shows economists expect one more quarter-point cut, to 13.50%, at the meeting on Tuesday 3 and Wednesday 4 November, and no further move by year-end . https://www.riotimesonline.com/brazil-focus-survey-inflation-october-2026/ - [2026-09-22] A prior Focus survey already showed economists trimming the year-end Selic forecast: economists now expect the Selic rate to reach 13.50% by year-end, down from the previous forecast of 13.75%. The revision suggests one additional 25-basis-point cut . https://www.investing.com/news/economy-news/brazil-economists-cut-2026-interest-rate-forecast-to-1350-93CH-4908896 - [2026-10-07] No December cut is currently baked into consensus: the median Focus forecast sees the easing cycle pausing after November, implying only a sixth cut in 2026 under the base case, not a seventh. https://www.riotimesonline.com/brazil-focus-survey-inflation-october-2026/ BOTTOM LINE: As of 2026-10-07, five qualifying 2026 Selic cuts have already occurred (March, April, June, August, September), with a sixth highly likely at the 3-4 November meeting given ~91% market-implied odds and Focus-survey consensus; but the Focus median currently expects no further cut in December, implying the base case stops at six cuts — just short of the seven needed for "Yes," though the December 8-9 meeting remains a live swing event that could still tip the outcome if inflation or activity data soften further. NOT FOUND: Market-implied probability for the December 8-9, 2026 Copom meeting specifically (only November-meeting odds were found); official BCB press release/ata for the September 16 decision text was not directly fetched (confirmed via secondary sources instead).
report: base rate
- [2026-09-16] The Selic stands at 13.75% after the Copom's fifth consecutive 2026 cut (25bp) on 15-16 September, following cuts in March (to 14.75%), April (to 14.50%), June (to 14.25%) and August (to 14.00%) from the 15.00% cycle peak. source confirms cumulative cuts since March 2026 total 125 basis points as of mid-September . This puts the running 2026 tally at 5 qualifying cuts, with 2 Copom meetings remaining in 2026 (Nov 3-4, Dec 8-9) — so hitting "7 or more" requires cuts at both remaining meetings. https://www.bcb.gov.br/en - [2026-10-05] The BCB's official Focus survey (collected through Oct 2, published Oct 5) shows economists see 2026 growth at 1.85%, the Selic at 13.50% by December and the real at R$5.20 per US dollar — implying the median analyst base case is only ONE more 25bp cut this year (to 13.50%), i.e. 6 total cuts, short of the 7-cut threshold. https://www.riotimesonline.com/brazil-focus-survey-inflation-october-2026/ - [2026-09-21] A week after the September cut, the Selic was forecast to fall to 13.5%, down from 13.75% previously, according to the weekly Focus survey, with 77 of 140 respondents projecting 13.50% for year-end 2026, reinforcing that consensus expects only one further cut, not two. https://uk.investing.com/news/stock-market-news/brazil-economists-lower-2026-selic-forecast-after-rate-cut-93CH-4876062 - [2026-10-07] Polymarket's "Bank of Brazil decision in November" market prices a 25bp decrease at 80%, a 50+bp decrease at 13.4%, and no change at 8% for the November meeting, while the companion December-decision market shows a 25bp decrease around 48-49%. Combined, this implies roughly even-to-somewhat-below-even odds that BOTH remaining meetings deliver cuts (needed for the 7-cut threshold). https://polymarket.com/event/bank-of-brazil-decision-in-november-1785878499354 - [2026-10-05] Press commentary notes the minutes/tone from Copom stressed caution: earlier in the cycle (August decision) the committee used language of "serenidade e cautela" and said inflation expectations remain "desancoradas," requiring continued tight monetary conditions , a hawkish-leaning bias that argues against an aggressive back-to-back cutting pace in Nov-Dec. https://www.riotimesonline.com/brazil-copom-minutes-caution-selic-2026 - [2026-10-06] Inflation has been drifting above target: the Focus survey's 2026 IPCA forecast rose to 5.01%, well above the 4.5% ceiling, described as a "third straight weekly increase," which historically has been associated with the BCB slowing or pausing cuts rather than accelerating them. https://www.riotimesonline.com/brazil-focus-survey-inflation-october-2026/ - [HISTORICAL BASE RATE] Comparable past Selic easing cycles rarely delivered 7+ cuts within a single calendar year, because Copom meets only 8 times annually (roughly every 45 days) and typically does not cut at every meeting. In the 2023-2024 cycle, the rate was cut six times by 0.5 points and once by 0.25 points between August 2023 and May 2024 — i.e., 7 total cuts, but spread across two calendar years (roughly 3 in 2023, 4 in 2024), not concentrated in one year. https://en.mercopress.com/2024/11/07/brazil-s-copom-raises-selic-rate-to-11.25 - [HISTORICAL PRECEDENT FOR YES] The 2016-2017 cycle is a rarer counter-example where near-every-meeting cutting did occur within a calendar year: by September 2017 the Selic had fallen for the eighth straight rate decline, bringing borrowing costs to the lowest since 2013 , with that cycle having begun in October 2016 and continuing through most of 2017's eight Copom meetings — demonstrating that 7+ cuts in a year is achievable but only under an unusually committed, uninterrupted and aggressive cutting mandate, which is not the tone currently signaled by Copom. https://tradingeconomics.com/articles/09062017210653.htm - [2026-10-06] Current official schedule confirms 2026 Copom meeting dates as 27-28 Jan, 17-18 Mar, 28-29 Apr, 16-17 Jun, 4-5 Aug, 15-16 Sep, 3-4 Nov, 8-9 Dec — eight meetings total, consistent with the standard ~45-day cadence, with exactly two meetings remaining in the current trading window. https://www.bcb.gov.br/en/monetarypolicy/committee NOT FOUND: An authoritative, explicit historical count of "number of calendar years since Selic inflation-targeting began (1999) in which total cuts reached ≥7" (i.e., a clean statistical base rate across all cycles) could not be located; the analysis above instead relies on reconstructing the two most recent major easing cycles (2016-2019, 2023-2024) plus the current 2026 cycle from primary central-bank and news sources. BOTTOM LINE: The outside view is unfavorable to YES: Copom's 8-meetings-per-year cadence plus the current gradualist, caution-emphasizing 25bp-per-meeting pace has produced 5 cuts through September 2026, and both the BCB's own Focus consensus (13.50% year-end, implying only 6 total cuts) and historical precedent (7+ cuts within one calendar year is the exception, not the rule, achieved mainly in the unusually aggressive 2017 cycle) suggest reaching 7 cuts requires an above-consensus acceleration — plausible via Polymarket's ~80% November cut odds but only a coin-flip December cut on top of that.
report: yes case
YES means: The Selic target is cut at both remaining 2026 Copom meetings (Nov 3-4 and Dec 8-9), bringing the cumulative 2026 tally to 7 discrete decreases (from the already-confirmed March, April, June, August and September cuts). - [2026-10-07] The Nov 4 decision is already priced as near-certain by markets: Polymarket's "Bank of Brazil decision in November" contract shows a 25bps decrease at 80% and a 50+bps decrease at 13.4% — combined, over 93% odds of at least one more cut in November, which would be cut #6. https://polymarket.com/event/bank-of-brazil-decision-in-november-1785878499354 - [2026-10-07] Crucially, the companion December contract is not priced as a pause: Polymarket's "Will the Bank of Brazil decrease the target for the Selic rate by 25 bps at the December meeting?" market shows 48% — essentially a coin-flip for a seventh cut, far from consensus's "no change" base case. https://polymarket.com/event/bank-of-brazil-decision-in-november-1785878499354 - [2026-09-16] XP Macro, one of Brazil's most-cited sell-side shops, explicitly forecasts the easing cycle continuing at every remaining meeting, "o Copom continuará reduzindo a taxa básica de juros em 0,25 p.p. nas próximas reuniões," projecting Selic at 13.25% by year-end — arithmetically exactly 7 cuts (13.75%→13.50%→13.25%) from the current level. https://www.infomoney.com.br/economia/taxa-selic-copom-corta-juros-13-75-set-2026/ - [2026-09-16] The same article cites Nomos's chief economist noting the Copom's own September statement flagged that both headline and core inflation are "agora abaixo do teto" (now below the ceiling), explicitly providing room to maintain the cutting pace rather than pause. https://www.infomoney.com.br/economia/taxa-selic-copom-corta-juros-13-75-set-2026/ - [2026-09-16] APAS's chief economist argues Brazil retains "um dos maiores juros reais do mundo" (one of the world's highest real interest rates), a structural argument for front-loading cuts while the economy cools, rather than pausing early. https://www.infomoney.com.br/economia/taxa-selic-copom-corta-juros-13-75-set-2026/ - [2026-10-05] The presidential race unexpectedly went to a runoff, with right-wing Senator Flávio Bolsonaro — seen by markets as more fiscally orthodox/market-friendly — leading Lula 47.03% to 45.16% in the first round and viewed by analysts as "the clear favorite" heading into the Oct. 25 second round; a market-friendly election outcome removes a key fiscal-risk headwind that Copom had cited as a reason for caution, potentially freeing the committee to validate a December cut once the political calendar clears. https://www.americasquarterly.org/article/reaction-flavio-bolsonaro-and-lula-advance-to-brazils-presidential-runoff/ - [2026-09-25] While the September IPCA-15 print surprised to the upside at 0.70% m/m (12-month at 4.47%), the statistical agency and independent economists attributed most of the surge to the one-off reversal of the "Bônus de Itaipu" electricity discount, with one economist calculating that excluding the energy component the reading would have been only 0.41% — supporting the case that disinflation remains intact once the distortion passes, leaving room for Copom to resume cutting in December once the one-off effect fades from the 12-month comparison. https://agenciabrasil.ebc.com.br/economia/noticia/2026-09/previa-da-inflacao-oficial-de-setembro-fica-em-070-mostra-ibge - [2026-08-05] Historical precedent exists for near-uninterrupted multi-meeting easing cycles in Brazil: in the 2017 cycle the Selic fell for eight straight Copom decisions, demonstrating the committee is institutionally capable of consecutive cuts across all 8 annual meetings when the disinflation/growth-slowdown narrative is clear, which is structurally similar to the "cooling activity + moderating core inflation" narrative Copom itself endorsed in its own September communique. https://www.riotimesonline.com/brazil-copom-minutes-caution-selic-2026 BOTTOM LINE: The path to YES is narrow but concrete and already partly priced: a near-certain November cut (cut #6, ~93% market-implied) plus a coin-flip December cut (~48% priced), reinforced by at least one major sell-side shop (XP) explicitly forecasting exactly 7 cuts and by a market-friendly electoral shift that could remove the fiscal-uncertainty excuse Copom has used for caution. NOT FOUND: No official Copom communication or minutes from after the Oct 4 first-round election result were located discussing how the runoff outcome specifically affects the December policy calculus; full-month September IPCA (due Oct 9) was not yet available at time of research.
report: no case
YES means: the Central Bank of Brazil delivers 7 or more discrete Selic rate cuts during calendar year 2026 (counting all qualifying decreases from January through December, including the March/April cuts already banked). - [2026-10-07] Only two Copom meetings remain in 2026 (Nov 3-4, Dec 8-9) after five cuts already delivered through September, meaning reaching 7 requires a cut at both remaining meetings with zero misses — a "needs a perfect run" bar, not a base case. https://www.riotimesonline.com/brazils-financial-morning-call-for-wednesday-october-7-2026/ - [2026-10-06] Polymarket's companion December-decision market prices a 25bp cut at only ~48-50%, well below the ~91% priced for November, showing traders see December as a coin-flip at best, not a continuation lock-in. https://polymarket.com/event/bank-of-brazil-decision-in-november-1785878499354 - [2026-09-25] The September IPCA-15 preview jumped 0.70%, above the 0.55% consensus forecast and reversing August's deflation, pushing 12-month inflation to 4.47% — just under the 4.5% ceiling — driven by a 7.42% electricity spike as the Itaipu bonus expired. https://www.riotimesonline.com/brazil-ipca-15-september-2026-inflation/ - [2026-09-22] The Copom's own September minutes explicitly avoided committing to a November cut, stating decisions would depend on incoming data "evitando mudanças bruscas," and flagged that geopolitical conflicts and foreign rate decisions still weigh on the domestic policy calculus. https://agenciabrasil.ebc.com.br/radioagencia-nacional/economia/audio/2026-09/copom-sinaliza-cautela-sobre-novos-cortes-da-selic - [2026-09-17] Goldman Sachs's read of the September statement found Copom offered no explicit forward guidance and judged "espaço limitado no curto prazo para uma flexibilização adicional significativa," given BCB's own conditional IPCA projections (3.9% for Q4 2027, 3.2% for Q1 2028) sitting above target through the relevant horizon. https://www.moneytimes.com.br/o-detalhe-no-comunicado-do-copom-que-chamou-a-atencao-do-goldman-sachs-jcav/ - [2026-09-18] The post-decision communiqué "evitou sinalizar quais serão os próximos passos," neither committing to a November cut nor signaling a pause, explicitly conditioning the call on data in "um cenário de incerteza que... exige cautela e serenidade." https://portaldaautopeca.com.br/noticias/local/copom-evita-se-comprometer-com-novos-cortes-mantendo-cautela-na-reducao-dos-juros/ - [2026-09-18] A separate economist roundup (published ~19 days ago) characterized the committee's tone as deliberately avoiding a "cheque em branco" (blank check) for further cuts, preserving flexibility rather than pre-committing to back-to-back reductions through year-end. https://revistaoeste.com/economia/copom-mantem-cautela-e-evita-cheque-em-branco-para-novos-cortes-dizem-economistas/ - [2026-10-06] Separately, fiscal risk remains on Copom's radar: minutes reiterated that fiscal policy "precisam caminhar de forma harmônica" with monetary policy and flagged the pre-election spending calendar as a factor keeping the risk premium elevated — an added reason to stay cautious into December amid election volatility. https://www.contabeis.com.br/artigos/78771/ata-do-copom-corte-com-sinalizacao-de-cautela-aponta-riscos/ - [HISTORICAL] Comparable base rate: reaching 7+ cuts within a single calendar year has been the rare exception (achieved mainly in the uninterrupted 2017 cycle) rather than the norm for Brazil's roughly 8-meetings-per-year Copom cadence, reinforcing that the "stop at 6" scenario is the more probable outcome given the current cautious, data-dependent framing. BOTTOM LINE: With five cuts banked and only two meetings left, NO requires just one of the two remaining decisions (most plausibly December, priced near a coin-flip and shadowed by above-forecast September inflation, unanchored expectations, fiscal/election-year risk, and Copom's explicit refusal to pre-commit) to be a hold rather than a cut — a readily achievable outcome under the committee's stated cautious, data-dependent reaction function. NOT FOUND: No official Copom statement or minutes from after the September 16 decision addressing the December meeting specifically (the November decision had not yet occurred as of this research); no primary-source confirmation of the exact December Polymarket percentage beyond the aggregated Rio Times/Polymarket snippet (48-50% range cited across sources).

(0) Not yet resolved. Five 2026 cuts are confirmed per BCB and secondary sources: March, April, June, August and September, with the Selic now at 13.75%. Reaching 7 requires a cut at both remaining Copom meetings, Nov 3-4 and Dec 8-9. (a) About 2 months remain, with exactly two decisions left before the Jan 1, 2027 close. (b) Status quo, no further moves, leaves 5 cuts and resolves No. The consensus path in the Focus survey, a 13.50% year-end Selic, gives 6 cuts, which is also No. (c) No scenario: Copom cuts in November but pauses in December. Triggers would be the upside September IPCA-15 surprise, inflation expectations still drifting above target, fiscal and election risk, and the committee's explicit refusal to give a 'blank check'. (d) Yes scenario: November delivers cut #6, which markets price at ~91-93% across Polymarket readings. December then also cuts because the Itaipu electricity effect proves transitory, and a market-friendly runoff on Oct 25 eases the risk premium. XP's 13.25% year-end forecast is exactly this path. The Kalshi anchor is 74% and has risen sharply (+33 points in 7 days), perhaps reflecting post-election repricing. However, the independent Polymarket December 25bp contract sits near 48-50%, and the Focus median implies no December cut. Together these suggest roughly 0.92 × ~0.55 ≈ 50%. I blend toward the Kalshi anchor, since its recent move may reflect information my sources lag, and land at about 61%.

(0) The condition is not yet met. Five 2026 cuts are documented: March, April, June, August and September, taking the Selic to 13.75%. YES needs cuts at both remaining Copom meetings. (a) About 12 weeks remain, with decisions on Nov 4 and Dec 9. (b) If Copom holds from here, the count stays at 5 and the market resolves NO. Even the Focus consensus path of one more cut to 13.50% stops at 6, so the status quo and the consensus path are both NO. (c) NO scenario: Copom cuts in November but pauses in December. Its caution and refusal to give a 'blank check' would drive that, along with September IPCA-15 above forecast, 2026 IPCA expectations around 5%, and fiscal or election risk premia. (d) YES scenario: Copom keeps its 25bp-per-meeting pace, as XP Macro forecasts (13.25% year-end). The Itaipu-driven inflation spike fades, and a market-friendly runoff result on Oct 25 eases fiscal-risk concerns. Kalshi prices YES at 74%, up 33 points in a week, which suggests traders are reacting to information my research may not capture. Against that, Polymarket's December 25bp cut sits around 48%, and November is about 91-93%. That implies a joint probability of roughly 45-50%, unless the December figure is stale or excludes 50bp outcomes. I shade below the Kalshi anchor toward the independent Polymarket and Focus evidence, while respecting the sharp recent move.

The threshold is neither documented as met nor impossible: the reported BCB June decision, October 7 homepage reading and September coverage support five qualifying cuts, but the designated historical-rate page returned no usable table, leaving residual count-verification risk. Roughly 12 weeks remain until calendar-year eligibility ends on December 31, with scheduled decisions on November 4 and December 9; absent an extraordinary decision, both must deliver cuts. If the Selic target remains unchanged from today, the total stays at five and No wins. I anchor on Kalshi's live 74% Yes price but reduce it to 60%, judging December-pause risk underweighted given the October 5 Focus survey's reported 13.50% year-end median and September 22 coverage of Copom's explicitly data-dependent guidance. Related Polymarket November odds around 91–93% support a sixth cut, but the reported December 48–50% quote covers only a 25-basis-point outcome and is linked to a November-market URL, so I substantially discount it rather than substitute it for the Kalshi anchor. A plausible No scenario is a November cut followed by a December hold as inflation pressure and unanchored expectations persist, leaving six cuts. A plausible Yes scenario is continued gradual easing at both meetings as underlying inflation and activity soften, consistent with XP's September 16 forecast of a 13.25% year-end Selic; this requires maintaining the existing pace, not accelerating it. Because the contrary evidence is public and imperfectly verified, I retain substantial weight on Kalshi's higher probability, while the unavailable resolution table and uncertain December quote limit forecast confidence.

Kalshi's live 74% Yes price is my anchor; I lower it to 58% because the October 5–6 Focus reporting forecasts 13.50% year-end Selic, suggesting December-pause risk is underweighted, reinforced by September's inflation surprise and cautious Copom minutes. Resolution is neither already met nor impossible: the reported BCB September target of 13.75% and the decision chronology support five qualifying cuts, although the named official historical-rate page returned no usable table. Roughly 12 weeks remain until the December 31 calendar-year cutoff, with scheduled decisions on November 4 and December 9; January 1 is the trading close, not an additional qualifying day. If nothing changes, the tally remains five and No wins. A concrete No scenario is a November cut followed by a December hold, leaving six cuts; a larger November reduction still counts only once. Yes ordinarily requires cuts at both remaining meetings, supported by XP's September 16 forecast of 13.25% year-end Selic and a plausible continuation of gradual easing if inflation moderates. The reported Polymarket meeting prices are context rather than another anchor for this exact question, especially because the weakly verified December quote concerns exactly a 25-basis-point reduction, not every possible cut. Historical rarity carries little weight after five consecutive cuts, while incomplete official-table verification and uncertain December pricing leave residual settlement and evidence risk that temper both my downward adjustment and confidence.

(0) The condition is not already met: BCB and contemporaneous reports document five 2026 cuts through September, while the direct resolution-source fetch was truncated and cannot independently verify settlement; cuts at both remaining meetings are still required. (a) About 85 days remain in calendar 2026, with the decisive scheduled announcements on November 4 and December 9. Kalshi’s 74% YES price is the anchor, but I shade below it because the latest Focus median projects only 13.50% at year-end, implying one additional cut, while Polymarket prices a November cut above 90% but only a 25-basis-point December cut near 48%; some probability of a larger December cut keeps the overall any-cut likelihood above 48%. (b) If policy remains unchanged from today, the tally stays at five and the market resolves No. (c) The leading No scenario is a November cut followed by a December hold as Copom responds to above-forecast inflation, unanchored expectations, and fiscal uncertainty. (d) Yes occurs if cooling activity, moderating underlying inflation, or reduced post-election fiscal risk produces cuts at both meetings, consistent with XP’s 13.25% year-end forecast.

Yes: 61% No: 39%
Mean of 5 draws (0.61, 0.60, 0.60, 0.58, 0.64). (0) Not yet resolved. Five 2026 cuts are confirmed per BCB and secondary sources: March, April, June, August and September, with the Selic now at 13.75%. Reaching 7 requires a cut at both remaining Copom meetings, Nov 3-4 and Dec 8-9. (a) About 2 months remain, with exactly two decisions left before the Jan 1, 2027 close. (b) Status quo, no further moves, leaves 5 cuts and resolves No. The consensus path in the Focus survey, a 13.50% year-end Selic, gives 6 cuts, which is also No. (c) No scenario: Copom cuts in November but pauses in December. Triggers would be the upside September IPCA-15 surprise, inflation expectations still drifting above target, fiscal and election risk, and the committee's explicit refusal to give a 'blank check'. (d) Yes scenario: November delivers cut #6, which markets price at ~91-93% across Polymarket readings. December then also cuts because the Itaipu electricity effect proves transitory, and a market-friendly runoff on Oct 25 eases the risk premium. XP's 13.25% year-end forecast is exactly this path. The Kalshi anchor is 74% and has risen sharply (+33 points in 7 days), perhaps reflecting post-election repricing. However, the independent Polymarket December 25bp contract sits near 48-50%, and the Focus median implies no December cut. Together these suggest roughly 0.92 × ~0.55 ≈ 50%. I blend toward the Kalshi anchor, since its recent move may reflect information my sources lag, and land at about 61%.
