A Quaest poll released this Monday and cited by G1 Globo and Folha de S.Paulo showed Lula with 39% support in the first round, while Flávio Bolsonaro registered 34%.

According to the published data, the five-point gap is outside the two-percentage-point margin of error, so both moved past the technical tie seen in the previous measurement.

In the same survey, Augusto Cury and Ronaldo Caiado are each at 4%, Renan Santos at 3% and Romeu Zema at 1%. Samara Martins does not reach 1% in this round. Undecided voters account for 5%, and those who said they would vote blank, spoil their ballot or not vote reach 10%.

In the spontaneous question, where no list of candidates is presented, Lula gets 31% and Flávio Bolsonaro 27%. The undecided share in that scenario reaches 31%.

For a possible second round between Lula and Flávio Bolsonaro, the poll shows 42% for each. In other matchups, Lula appears with 43% against Caiado, who has 40%; with 42% against Augusto Cury, who reaches 33%; with 42% against Renan Santos, who registers 39%; and with 46% against Romeu Zema, who gets 30%.

G1 Globo also reported that government approval stood at 46%, while disapproval was 49%.

The survey was commissioned by Globo and the newspaper O Globo. According to Brazilian media, 2,004 people aged 16 or older were interviewed between September 24 and 27, with a 95% confidence level. The study is listed under registration BR-06520/2026.
