Veritá Poll of 40,500 Voters Puts Flávio Bolsonaro Ahead of Lula Eight Days Before Brazil Votes
Key Facts
—The country — Brazil, Latin America’s largest economy with about 210 million people, votes for a president on Sunday 4 October, with a runoff on 25 October if nobody wins outright.
—The background — President Luiz Inácio Lula da Silva seeks a fourth term. Senator Flávio Bolsonaro carries the conservative banner after his father, former president Jair Bolsonaro, was barred from running and imprisoned.
—Why it is news — Eight days before the vote, the largest survey of the entire campaign breaks from the pack: while five other institutes show a first-round Lula lead or a dead heat, Veritá’s giant sample puts Flávio Bolsonaro in front.
—What happened — Veritá released its self-commissioned national poll on 26 September 2026: Flávio Bolsonaro 45.53 percent, Lula 41.76 percent in the first round, a numerical lead of 3.77 points.
—The numbers — The institute heard 40,500 voters between 10 and 19 September, by far the biggest fieldwork of the 2026 race and roughly twenty times a standard national survey.
—What it means for you — One outlier house does not settle a race. If you hold Brazilian assets or plan a move, price in both men winning rather than the leader of the largest single survey.

The Biggest Sample of the Race Breaks From the Pack
Veritá’s new national wave is the largest single poll fielded in the 2026 campaign: 40,500 interviews conducted over ten days, from 10 to 19 September, and released on Friday 26 September. Its first-round reading puts Senator Flávio Bolsonaro at 45.53 percent against 41.76 percent for President Luiz Inácio Lula da Silva, a numerical gap of 3.77 points that the institute projects as roughly three million votes.
No other house currently shows a first-round lead for the challenger. Datafolha’s wave released 24 September has Lula ahead 40 to 36, AtlasIntel/Bloomberg reads 45.8 to 43.4 for Lula, and Genial/Quaest’s mid-September wave put the president up 37 to 33. Veritá is therefore the outlier — but an outlier with a sample twenty times the usual size, which is why its number moves the conversation even among analysts who doubt it.
Veritá’s Own Series Shows the Same Direction
The house’s previous registered national wave, fielded 1 to 4 September and released 20 September, already had Flávio Bolsonaro fractionally ahead in the first round at 38.9 to 38.4, and clearly ahead in a runoff at 48.5 to 43.1. The new 40,500-interview wave widens that first-round reading from half a point to 3.77 points. Within Veritá’s own series, the trend line favors the senator; within the broader polling band, every other institute still disagrees.
Our poll tracker reads the race as a band rather than a number: the houses currently spread the first round across roughly eight points, far wider than any single margin of error. Veritá defines the pro-Flávio edge of that band; Datafolha and AtlasIntel define the pro-Lula edge.
How to Read an Outlier Eight Days Out
Giant samples shrink random error, but they do not fix a house effect — the systematic tilt that comes from how a pollster reaches and weights voters. Veritá has leaned toward the conservative camp all cycle, just as some houses lean toward the president. The honest reading is that the true first-round number sits somewhere inside the band, and the band says the race is tight.
What the Veritá wave does settle is momentum: its own series shows the challenger consolidating rather than fading in the final stretch. Whether that consolidation is enough to force the race he wants — or to win it outright on 4 October — is the question the last week of fieldwork will answer.
What Comes Next
The final campaign week brings the last full waves from every major institute before the 4 October vote, and the electoral court’s rules freeze new releases in the days immediately around the ballot. Each new survey lands here in our coverage and in the tracker below within hours of release.
