Key Points
— An AtlasIntel/Bloomberg poll shows Flávio Bolsonaro numerically ahead of Lula for the first time in a second-round simulation, 47.6% to 46.6%, a statistical tie within the one-point margin of error
— Both frontrunners carry negative images above 50% — Flávio at 56% and Lula at 51% — while Congress leaders Alcolumbre and Motta are rejected by 81% of voters
— Lula leads all first-round scenarios with 45.9% but his positive image dropped three points since February, while government disapproval hit 53.5%
The latest Brazil election poll from AtlasIntel and Bloomberg shows Senator Flávio Bolsonaro numerically leading President Lula for the first time in a second-round simulation — 47.6 percent to 46.6 percent — a statistical tie within the survey’s one-point margin of error. The Rio Times, the Latin American financial news outlet, reports that the shift extends a trend that has narrowed steadily since December, when Lula led by 12 points.
The poll of 5,028 respondents, conducted between March 18 and 23, also measured how Brazilians view their political class — and the results are bleak for nearly everyone. Flávio carries the highest negative image among presidential candidates at 56 percent, while Lula stands at 51 percent. Both share an identical 43 percent positive rating.
First Round: Lula Leads but Weakening
In the first round, Lula still commands the field with 45.9 percent against Flávio’s 40.1 percent, followed by Renan Santos at 4.4 percent, Ronaldo Caiado at 3.7 percent, and Romeu Zema at 3.1 percent. But the trajectory is working against the president: his positive image fell three points from February while government disapproval reached 53.5 percent.
Flávio’s rise from roughly 20 percent late last year to 40 percent represents one of the fastest opposition consolidations in recent Brazilian history. The speed reflects both his father’s prison endorsement and a broader anti-incumbent mood. Notably, if Lula is replaced by Fernando Haddad as the PT candidate, Flávio takes the outright lead at 40.1 percent to 37.6 percent.
An Unpopular Political Class
The poll’s image ratings reveal the depth of voter frustration with Brazilian politics. Senate president Davi Alcolumbre and House speaker Hugo Motta both carry 81 percent negative ratings — an extraordinary rejection for leaders of Congress. Former Finance Minister Fernando Haddad, who may be Lula‘s backup candidate, has a 57 percent negative image, the worst among potential presidential contenders.
São Paulo governor Tarcísio de Freitas, who endorsed Flávio and will seek reelection instead, holds the most competitive profile: 45 percent negative versus 44 percent positive. Among other tested candidates, Romeu Zema carries 51 percent rejection while Ronaldo Caiado has 49 percent — numbers that explain why neither has broken through as a viable third option.
What the Brazil Election Poll Means for October
The structural picture is clear: Brazil’s October election is now a genuinely competitive race between two candidates that most voters view unfavorably. Lula’s first-round advantage gives him the easier path, but the second-round tie — and the historical trend showing Flávio gaining roughly three points per month since January — means the race could flip entirely by summer. Lula’s declining approval adds further pressure.
For markets, the implications are direct. A Lula reelection likely means continuity of the current spending framework with limited reform ambition, while a Flávio victory introduces uncertainty around fiscal policy and the independence of the Central Bank.
With both outcomes now plausible seven months before the vote, political risk will increasingly drive the Selic rate path, the real, and equity valuations through the rest of 2026. The era of comfortable Lula leads is over — and both sides know it.
