Brazilians cast ballots Sunday in the presidential runoff between President Luiz Inácio Lula da Silva of the Workers Party and Senator Flávio Bolsonaro of the Liberal Party. The last Datafolha survey before the vote puts Flávio at 51 percent of valid votes and Lula at 49 percent, Folha de S.Paulo and G1 reported. Before rounding, Folha said the split was 50.89 percent to 49.11 percent.

Datafolha interviewed 4,050 people on October 23 and 24 in 124 cities. The margin of error is two percentage points either way at 95 percent confidence, Folha and G1 reported. Datafolha labels the race a technical tie. The TSE registry number is BR-09540/2026, G1 said. In the prior midweek round, both candidates sat at 50 percent of valid votes in rounded numbers, Folha reported, after Flávio held a four-point edge earlier in the runoff.

Among voters Datafolha judged most likely to turn out, Flávio leads 52 percent to 48 percent. Flávio is stronger with men, evangelicals, and voters in the South and Southeast. Lula leads among women, younger voters ages 16 to 24, Catholics, and in the Northeast, Folha and G1 reported. About 95 percent of voters say they are fully decided. Flávio’s backers more often say they are voting to defeat Lula; Lula’s backers more often say he is the best choice.

Polls close at 5 in the afternoon Brasília time, which is 4 in the afternoon Eastern. Official results are expected later Sunday night and are a separate follow-up for the Editor.

Electronic voting machines will tabulate results as polls close. Campaigns spent the final hours pressing turnout in São Paulo, Rio, and the Northeast, where Lula’s base is strongest and Flávio needs to hold his lead among evangelicals and southern voters.

What we know: The last Datafolha valid-vote read is 51-49 for Flávio within the margin. Turnout models still show a tight race.
What we don't: Who will win once ballots are counted.
