In brief

Brazilians voted Sunday, October 4, 2026, in a presidential election pitting President Luiz Inácio Lula da Silva against Senator Flávio Bolsonaro, the eldest son of imprisoned former President Jair Bolsonaro. Pre-election polls showed Lula with a narrowing lead, and because no candidate was expected to clear 50% of valid votes outright, a second-round runoff on October 25 was considered likely.

Who is on the ballot

President Luiz Inácio Lula da Silva, 80, of the Workers' Party is seeking a fourth term in office, according to Al Jazeera. His main challenger is Senator Flávio Bolsonaro, 45, of the Liberal Party, the eldest son of former President Jair Bolsonaro.

Jair Bolsonaro is not on the ballot. He is serving a 27-year prison sentence over a plot to overturn his 2022 election loss to Lula, according to Al Jazeera. With his father imprisoned, Flávio Bolsonaro has emerged as the standard-bearer of Brazil's right, and Al Jazeera reported that he has described his father's conviction as political persecution.

What the polls showed before voting

Four major pollsters released surveys in the final days before the vote. All showed Lula ahead of Bolsonaro in a simulated first round, but with margins tight enough that none of the firms projected an outright majority.

PollsterField datesFirst round: Lula / BolsonaroRunoff: Lula / Bolsonaro
CNT/MDA (Reuters)Sept. 30–Oct. 247.8% / 42.1%47.3% / 43.1%
DatafolhaOct. 145% / 40%48% / 45%
QuaestSept. 24–2739% / 34%42% / 42%

A fourth poll, by AtlasIntel for Bloomberg, put Lula at 46% to Bolsonaro's 43% in a runoff scenario, according to Al Jazeera's reporting; the poll's exact field dates were not specified in that account. The Quaest survey had a margin of error of 2 percentage points; the CNT/MDA poll's margin of error was 2.2 points, meaning several of the runoff gaps were within or close to statistical uncertainty.

How Brazil's two-round system works

Under Brazilian electoral law, a presidential candidate must win more than half of valid votes to be elected outright in the first round. With almost 160 million registered voters choosing a president, members of Congress, governors and senators, according to Al Jazeera, polling pointed to no candidate reaching that threshold, making an October 25 runoff between the top two finishers likely.

Closing campaign messages

Lula held a rally in São Paulo on Saturday that his campaign said drew record attendance, according to Al Jazeera. He framed the election as a choice between 'democracy and barbarism' and warned against foreign interference in the vote.

Flávio Bolsonaro led a motorcycle caravan through São Paulo state before a rally in Rio de Janeiro, where, per Al Jazeera, his father's portrait featured prominently. Bolsonaro expressed confidence he could win outright in the first round.

Investigations around Flávio Bolsonaro

Al Jazeera reported that Flávio Bolsonaro faces an investigation linked to a film-funding scandal and to allegedly defamatory statements he made about Lula. These matters are under investigation and have not resulted in a conviction.

What happens next

Riotimesonline reported that polling stations were set to close at 5 p.m. Brasília time (4 p.m. ET), after which Brazil's Superior Electoral Court (TSE) would begin publishing official counts, with roughly 97% of votes historically tallied by around 9:30 p.m. local time. If neither Lula nor Bolsonaro wins a majority, the runoff is scheduled for October 25, 2026.
