Key Points
— The April BTG Pactual/Nexus poll released Monday morning April 27 — the first major election poll after the Workers’ Party closed its 8th National Congress on Sunday — shows President Luiz Inácio Lula da Silva recovering a more comfortable first-round lead while simultaneously losing the second-round comfort margin against Goiás Governor Ronaldo Caiado and Minas Gerais Governor Romeu Zema. The previous March wave had shown Lula and Senator Flávio Bolsonaro statistically tied in the first round and dead even in the runoff at 46% each.
— The April reading confirms two structural shifts: Lula has consolidated his floor among PT-aligned voters following the Brasília Congress and the dairy-chain investment announcement Monday morning, but the right has produced multiple credible runoff alternatives. Caiado and Zema, who were polling at 4% each in March first-round simulations, have now demonstrated they can compete with the president in head-to-head runoff scenarios — a finding that reshapes the strategic logic for the conservative bloc heading into October.
— The methodology is consistent with prior waves: Nexus Pesquisa e Inteligência fielded the survey by telephone (CATI) with approximately 2,000 voters across the 26 states and the Federal District, with a margin of error of two percentage points and 95% confidence. The poll is registered with the Superior Electoral Court (TSE). The 161 days remaining until the October 4 first round leave room for further movement, but the post-Congress baseline is now formally set.
The first major BTG Nexus poll after Sunday’s PT Congress closing shows the Brazilian race converging on a structural finding: Lula leads the first round comfortably, but three different opposition candidates — Flávio Bolsonaro, Caiado, and Zema — now plausibly tie him in a runoff.
A new poll has reset the Brazilian electoral picture less than 24 hours after the Workers’ Party closed its 8th National Congress. The Rio Times, the Latin American financial news outlet, reports that the BTG Nexus poll released Monday morning April 27 confirms President Lula has recovered first-round breathing room — but at the cost of seeing his second-round comfort against Goiás Governor Ronaldo Caiado and Minas Gerais Governor Romeu Zema disappear. The poll, the second of the cycle from the BTG Pactual-Nexus partnership, sets the post-Congress baseline that will define the next three weeks of strategic positioning.
The headline framing from Money Times — that Lula has “recovered first-round advantage but ties Flávio Bolsonaro, Caiado, and Zema in the second round” — captures the structural shift. The March wave had Lula and Flávio Bolsonaro statistically tied at 41-38 in the first round and dead-even at 46% each in the runoff, with Caiado and Zema struggling to break out of single-digit first-round territory.
What the BTG Nexus Poll Captures
The April reading is the first comprehensive electoral poll fielded after several converging events: the PT 8th Congress (April 24-26), Lula’s basal-cell carcinoma surgery and recovery (April 24-26), the Banco Master CPI political-payments revelations expanding through April, and the Trump White House Correspondents Association dinner shooting that produced an unsolicited Lula condemnation Saturday. Each of those events had the potential to move the polling — and the cumulative effect appears to have hardened the Lula floor while raising the conservative ceiling.
Money Times’ release framing emphasizes the “recovery” of Lula’s first-round advantage — language that signals Lula’s first-round numbers are now further from the technical-tie zone than they were in March. The exact April numbers will determine whether the recovery represents a one-to-two-point movement (within sample noise) or a structural three-to-five-point shift consistent with the Datafolha April 11 reading.
The runoff finding is the more consequential signal. If Caiado and Zema have moved from “Lula wins by 5-10 points” in March to “Lula tied” in April, the conservative bloc has produced two credible runoff candidates beyond Flávio Bolsonaro. That changes the PT campaign’s calculation of which opposition figure represents the highest threat — and, by extension, where to focus first-round attack messaging.
Why the Right’s New Optionality Matters
Throughout late 2025 and early 2026, the assumption inside the PL machinery and the Bolsonaro-aligned political ecosystem has been that Flávio Bolsonaro represents the only viable conservative national candidate — with Tarcísio de Freitas held in reserve as a backup if the Bolsonaro brand becomes electorally toxic before October. The April BTG Nexus poll suggests the right may now have three credible candidates, not one or two.
Caiado, the Goiás governor expected to be confirmed as PSD’s presidential candidate, has been quietly building a pragmatic-conservative profile that targets the moderate right vote that the Bolsonaro family alienates. His April 25 Reagrishow comment that the 2026 election will determine who reaches the second round — and his call for opposition convergence — reflects that strategic positioning.
Zema, the Novo Party governor, has used his recent confrontation with the STF — particularly Justice Gilmar Mendes — to consolidate the pro-business libertarian-conservative niche. His confrontational social-media presence has produced measurable polling momentum: from 4% first-round in March to a runoff number against Lula that is now within the margin of error.
The Methodology Constants
Nexus Pesquisa e Inteligência fielded the April wave consistent with the March methodology: telephone interviews (CATI), approximately 2,000 voters above age 16, all 26 states plus the Federal District, two-percentage-point margin of error at 95% confidence. The poll is registered with the Superior Electoral Court (TSE).
The Nexus April poll is the most prominent of the early-week political data points and arrives ahead of Datafolha’s expected May reading and the Genial/Quaest April 30 release. Together those three tracking instruments will determine whether the BTG Nexus April reading represents a sustained trend or a one-poll outlier.
The March wave’s most-cited cross-tab finding — that 49% of voters reject Lula “de jeito nenhum” against 48% rejecting Flávio Bolsonaro — sets the rejection-rate baseline. If the April rejection numbers hold steady, the polarization remains structural rather than shifting. If Lula’s rejection has dropped below the high-40s zone while Flávio’s has held, the late-April improvement reflects genuine demographic re-engagement rather than sample noise.
Lula’s Strategic Window
The PT campaign now operates with a clear first-round message: Lula vs Flávio Bolsonaro, with the latter framed as the dangerous-continuity Bolsonaro family extension Haddad described in his Sunday keynote at the PT Congress as the “family that has only delivered chaos.” That framing serves a first-round consolidation purpose.
The runoff exposure is different. If Lula reaches the runoff against Caiado, the Goiás governor’s pragmatic-conservative governance record — agrobusiness emphasis, security-focused, fiscal conservatism — is harder to attack as “extremist” than the Flávio profile. Against Zema, the libertarian-anti-state framing intersects with the STF confrontations Zema has been cultivating, making him the candidate most aligned with the broader anti-establishment current that has carried Trump in the US, Milei in Argentina, and the Bolsonaro family in Brazil.
PT national president Edinho Silva’s Sunday closing remark — that the campaign is “90% organized in the states” — was an operational signal. The April poll suggests the strategic frame still requires work: the campaign needs to decide whether to focus first-round attack messaging on the Bolsonaro family alone or to extend it to the broader conservative-governor alternative bloc.
Why the BTG Nexus Poll Matters for Markets
The election polling matters to Brazilian asset prices through one mechanism: the Lula-vs-conservative-governor scenario produces lower fiscal-and-monetary-uncertainty pricing than the Lula-vs-Flávio-Bolsonaro scenario. If markets begin pricing a higher probability that the runoff will be Lula vs Caiado or Lula vs Zema rather than Lula vs Flávio, the Brazilian risk premium compresses regardless of which candidate ultimately wins.
Both Caiado and Zema project as more market-friendly than Flávio Bolsonaro on fiscal and structural-reform questions. A Caiado or Zema runoff trajectory therefore reduces the tail risk that has been built into BRL forwards and the Ibovespa risk premium since the Trump tariff shock in mid-2025.
The Polymarket prediction-market pricing currently puts Lula and Flávio Bolsonaro at approximately 40% probability each of winning the October 4 first round, with Tarcísio at lower but rising probability and Caiado/Zema below 5% each. If the April BTG Nexus reading holds in the next two waves of polling, that prediction-market distribution will shift visibly — and the Brazilian forward curve will shift with it.
What the Next Three Weeks Test
Three immediate signals will tell whether the BTG Nexus April reading is the new baseline or an outlier. First: the Datafolha May wave, expected within 10 days, will independently test the Lula recovery and the Caiado/Zema rise.
Second: the Quaest April 30 release will provide a third tracking line. Third: the PSD’s formal candidate confirmation around Caiado will either lock in his polling momentum or expose vulnerabilities the right would prefer not to surface.
For the PT, the Tarcísio question remains. If the São Paulo governor enters the race as the PL substitute for Flávio Bolsonaro, the runoff calculus shifts again — Tarcísio polls more competitively against Lula in São Paulo but less competitively in the Northeast. Haddad’s PT Congress keynote pointedly ignored Tarcísio, signaling that the PT machinery considers the São Paulo governor’s national candidacy an unlikely scenario for now.
The April BTG Nexus poll’s central message: the Brazilian race has converged on a Lula-comfortable-first-round, three-way-runoff-contest baseline. The 161 days to October 4 are now the operational window, and the tracking polls of May will determine whether the right has genuinely produced three credible candidates or whether the runoff convergence is a momentary post-Congress reset that fades by June.
