Brazil's October 4, 2026 presidential first round produced no outright winner, sending incumbent Luiz Inácio Lula da Silva and Flávio Bolsonaro into a runoff on October 25. The outcome has revived a recurring question in Brazilian politics: when, if ever, has a candidate won the presidency without a second round?
The constitutional majority rule
Article 77 of Brazil's 1988 Constitution sets the first round for the first Sunday of October and, if needed, a runoff for the last Sunday of the same month. To be declared president-elect in the first round, a candidate must obtain an absolute majority of valid votes — more than 50%, excluding blank and null ballots. If no one clears that bar, the two most-voted candidates compete again within 20 days of the result being announced, according to the constitutional text.
Two outright wins in 37 years
The two-round system has governed every direct presidential election since 1989, the first held under the 1988 Constitution. According to Rede98, a Brazilian news outlet, only two of those contests were decided in the first round: in 1994, Fernando Henrique Cardoso (PSDB) won with 54.27% of valid votes, and in 1998 he was re-elected with 53.06%. Every other presidential election since 1989 — including 2002, 2006, 2010, 2014, 2018 and 2022 — went to a second round, the outlet reported.
First-round outcomes in Brazilian presidential elections, 1994–2026| Election | Leading/winning candidate (1st round) | 1st-round share of valid votes | Outcome |
|---|
| 1994 | Fernando Henrique Cardoso | 54.27% | Won outright in 1st round |
|---|
| 1998 | Fernando Henrique Cardoso | 53.06% | Won outright in 1st round |
|---|
| 2002–2022 (six elections) | Varies by year | Below 50% | Decided in 2nd round |
|---|
| 2026 | Flávio Bolsonaro | about 47% | 2nd round scheduled, Oct 25, 2026 |
|---|
Why 2026 needs a second round
In the October 4, 2026 first round, Flávio Bolsonaro led with about 47% of valid votes, ahead of incumbent Lula's about 45%, according to Jornal do Cariri. Because neither crossed the 50% threshold required by Article 77, both advance to the October 25 runoff, the newspaper reported, noting that voting will run from 8 a.m. to 5 p.m. Brasília time and that campaigning, including a new televised debate and free airtime, resumes October 9 through 23.
The presidential race is not the only contest heading to a runoff. According to Itatiaia, seven of Brazil's 27 states — Rio de Janeiro, Acre, Amazonas, the Federal District, Espírito Santo, Rio Grande do Norte and Tocantins — will also hold second-round gubernatorial votes on October 25, because no candidate topped 50% of valid votes there either.
What the pattern shows
The historical record indicates that a first-round victory in Brazil has been the exception rather than the rule: two wins out of nine direct presidential elections held since the return to democracy in 1989. Both exceptions came under the same candidate, Fernando Henrique Cardoso, in the 1990s. Every election since 2002 — now including 2026 — has required voters to return for a second round before a president is declared elected.
