Neither candidate secured a first-round majority. Brazil now faces three weeks of campaigning before voters choose between Lula’s bid for a fourth term and Flávio Bolsonaro’s push to return the right to power.

BRASÍLIA, Brazil | October 5, 2026 — Brazil’s presidential election has produced a leader, but no winner. Senator Flávio Bolsonaro finished ahead of President Luiz Inácio Lula da Silva in Sunday’s vote, setting up an October 25 runoff that will determine whether the incumbent secures a fourth presidential term or the Bolsonaro family returns to the center of executive power.
The Brazil election runoff turns the contest into a direct choice between two sharply different political camps. Both candidates have substantial support. Neither has yet persuaded enough voters to win outright.
For Lula, the next three weeks offer an opportunity to recover from a disappointing first round. For Bolsonaro, they present the challenge of converting a narrow lead into a governing mandate.
What the First-Round Results Show
According to Agência Brasil, citing Brazil’s Superior Electoral Court, Bolsonaro received 47.03% of valid votes, compared with 45.16% for Lula, with 99.99% of voting machines tallied at the reported update.
Those figures put Bolsonaro ahead by approximately 1.87 percentage points. They represent a nearly complete count rather than a final certified result.
| Candidate | Party | Share of valid votes |
| Flávio Bolsonaro | Liberal Party, PL | 47.03% |
| Luiz Inácio Lula da Silva | Workers’ Party, PT | 45.16% |
Count status: Figures reported by Agência Brasil with 99.99% of voting machines tallied.
Brazil requires a candidate to receive more than half of valid votes to win the presidency in the first round. Blank and invalid ballots do not count toward that threshold. With neither contender crossing it, the two leading candidates advance to the October 25 vote.
Lula’s Challenge: Find Support Beyond His Base
Lula acknowledged that he had expected to win in the first round, Agência Brasil reported. He said he would begin a fresh campaign for the runoff.
The incumbent is seeking his fourth presidential term overall. Brazil’s Senate news agency notes that he previously served two terms before returning to the presidency in 2023 after defeating Jair Bolsonaro in the 2022 election.
His immediate task is clear: retain his existing supporters while reaching voters who chose another candidate or stayed home.
That requires a broader appeal than simply repeating the first-round campaign. Voters considering a switch will want reasons to support another Lula term, including what his administration would prioritize next.
Bolsonaro’s Challenge: Turn a Lead Into a Majority
Flávio Bolsonaro, a senator representing Rio de Janeiro and the son of former President Jair Bolsonaro, is making his first presidential bid, according to the Senate news agency.
After the results, he portrayed his performance as evidence that Brazilians wanted a change in leadership.
His first-place finish strengthens that argument. It does not settle the election.
A runoff changes the choices available to voters. People who supported smaller parties must now choose between the finalists, cast a blank or invalid ballot, or abstain. Bolsonaro must attract enough of those voters while protecting the support he already has.
The Trump Connection—and Its Limits
Bolsonaro’s relationship with U.S. President Donald Trump adds an international dimension to the race.
Reuters reported that Trump had hosted the senator at the White House and praised him publicly. However, the agency also reported that Trump had not formally endorsed a candidate.
That distinction matters. Political affinity and public praise should not be presented as an official endorsement.
Reuters identified the cost of living, corruption and public insecurity as central concerns in the campaign. Those domestic pressures give both candidates an incentive to explain how their next administration would improve everyday conditions.
Who Could Decide the Second Round?
The strongest clue lies beyond the two leading candidates.
Their combined share left approximately 7.8% of valid first-round votes with other contenders. That pool is larger than the gap between Bolsonaro and Lula, although it cannot be treated as a single voting bloc.
Turnout also matters. Brazil’s Senate news agency reported first-round abstention of approximately 21.08%. Mobilizing people who did not participate could affect the balance in the runoff.
These figures support a straightforward electoral assessment: both campaigns need to expand their appeal. Endorsements may help, but voters do not automatically follow the recommendations of the candidates they supported earlier.
INVC NEWS | BEYOND THE HEADLINE
A first-round lead measures support already won. A runoff tests how much more support a candidate can attract.
Bolsonaro enters the second round ahead. Lula remains within reach. The decisive questions are whether the challenger can broaden his coalition and whether the incumbent can win back voters who resisted another term.
Brazil will vote again on October 25. Until those ballots are counted, claims that either candidate has already secured the presidency go beyond the result.
