Flávio Bolsonaro and President Luiz Inácio Lula da Silva faced Brazilian voters on Sunday, October 4, in a highly polarized presidential election that could be decided only after a second round.
The first-round vote involved 12 presidential candidacies, but the campaign was dominated by the contest between Lula, who is seeking another term, and Bolsonaro, a senator from Rio de Janeiro running for the Liberal Party.

Voting ends as Brazil begins counting ballots
Brazil’s polling stations operated from 8 a.m. to 5 p.m. Brasília time under the schedule established by the Superior Electoral Court, known as the TSE.
The TSE said more than 158.7 million voters were eligible to participate in the 2026 general election.
The ballot also included races for governors, senators and members of the federal and state legislatures.
Official presidential results began to be released after 5 p.m. Brasília time as electronic ballot records were transmitted and processed.
The first figures were preliminary and could change as additional voting sections were added to the national total.
The TSE has directed voters to follow its official results system and mobile application for the count.
A final result cannot be determined from early partial figures alone.
Why the Lula and Flávio Bolsonaro race matters
The election has become a direct test between two competing political projects.
Lula’s campaign has presented the vote as a choice over the direction of Brazil’s democratic institutions, social programmes and environmental policies.
Bolsonaro has campaigned as the main conservative alternative, emphasizing public security, lower taxes, traditional social positions and opposition to the governing Workers’ Party.
The dispute also carries a strong family and political dimension.
Flávio Bolsonaro is the eldest son of former president Jair Bolsonaro, whose political movement remains influential among conservative voters even though he is not on the presidential ballot.
That connection has helped Bolsonaro consolidate support among voters seeking a return to the policies and rhetoric associated with the former president.
It has also made the contest a referendum, for many voters, on Jair Bolsonaro’s legacy and the years of political conflict that followed the 2022 election.
Campaign conflict reached Brazil’s electoral court
The confrontation between the two camps extended beyond campaign rallies and television advertising.
The TSE acknowledged an electoral investigation brought by Flávio Bolsonaro against Lula and Vice-President Geraldo Alckmin.
The case was accepted for further information before the court decided whether to move ahead with a substantive review.
Its existence reflects the broader legal pressure surrounding the campaign, including disputes over political advertising, alleged irregularities and the right to respond to campaign claims.
Electoral court proceedings can continue after voting day.
That means legal disputes may remain relevant even after the presidential result is known, particularly if either campaign challenges campaign conduct or seeks a judicial remedy.
A second round remains possible
Brazilian presidential elections require a candidate to win more than half of the valid votes to avoid a runoff.
If no candidate reaches that threshold, the two leading candidates advance to a second vote.
The TSE has scheduled an eventual second round for October 25, 2026.
Based on the structure of the race and the number of candidates, a runoff between Lula and Bolsonaro was widely considered possible before voting began, but only the official count can establish whether that will happen.
A second round would force both campaigns to expand their coalitions.
Candidates eliminated in the first round could become important sources of endorsements, volunteers and voters, while issues that received less attention during the opening stage could become central to the final campaign.
What happens next
The immediate focus is the TSE’s national vote total.
Election officials will continue receiving and processing ballot records from Brazil and from voters abroad before declaring the final status of the presidential race.
If a runoff is required, campaigning will resume under the rules governing the second round.
The final contest would then centre on turnout, regional voting patterns and whether supporters of other candidates transfer their votes to Lula or Bolsonaro.
Until the TSE completes the totalization, early leads should be treated as provisional.
The official election system remains the authoritative source for the result and for determining whether Brazil proceeds to a second round on October 25.
