On 4 October 2026, Brazil's first presidential round ended without any candidate winning an outright majority. Official election reporting put Senator Flávio Bolsonaro at 47.03% and President Luiz Inácio Lula da Silva at 45.16%, sending the two candidates to a runoff scheduled for 25 October. Bolsonaro therefore led the first round but did not win the presidency on 4 October.
The result transformed Bolsonaro from a senator and political heir to Jair Bolsonaro into a realistic contender for executive power and made the Bolsonaro movement's legal and democratic record central to the second-round campaign. He was a runoff finalist, not president-elect; the final officeholder remained undecided.
