In the first-round presidential election, Flávio Bolsonaro defeated Luiz Inácio Lula da Silva by over 2.2 million votes

Final campaign rallies preceded the second-round vote between Luiz Inácio Lula da Silva and Flávio Bolsonaro on 25 October. Economic priorities, public security and Brazil's international alignment remained central divisions; coverage of the final campaign day does not establish the result.

President Luiz Inácio Lula da Silva faces Senator Flávio Bolsonaro in a closely contested election. A Datafolha survey of 2,506 people, conducted 29 September–1 October across Brazil, put a hypothetical run-off at 48% to 45%; Reuters described the result as a statistical tie within the poll's two-point margin of error. The first round on 4 October produced a run-off between Lula and Flávio Bolsonaro.

Flávio Bolsonaro led President Luiz Inácio Lula da Silva in Brazil's first presidential round, with approximately 56 million votes to Lula's 53.7 million after 99.8% of votes were reported. Neither won a majority; the presidency will be decided in a runoff scheduled for 25 October.
