Brazil Heads to an Oct. 25 Runoff After Flávio Bolsonaro Edges Out Lula
Brazil will choose its president on 25 October in a runoff between Senator Flávio Bolsonaro and incumbent Luiz Inácio Lula da Silva. Neither won outright in the first round on 4 October.
With more than 98% of votes counted, Bolsonaro led with 47.3% to Lula's 44.8% The Guardian. The gap was 2.5 points. In Brazil, a candidate needs more than half of the valid votes to win in the first round, like a playoff that goes to a final when no one wins outright. Both fell short, so they have three weeks to chase the rest of the electorate.
The first round capped a crowded field. Twelve candidacies disputed the Presidency of the Republic, with the first round set for 4 October TSE. Behind the two leaders, Ronaldo Caiado took 2.2% and Renan Santos took 2.2%. No other contender broke through. The vote concentrated heavily in the top two tickets.
Lula, of the PT, ran with Geraldo Alckmin of the PSB as his running mate. Flávio Bolsonaro, of the PL, ran with Alfredo Gaspar of the PL. Bolsonaro, 45, campaigned under ballot number 22 for the Partido Liberal. He serves as a senator and is the eldest son of former president Jair Bolsonaro.
Down-ballot results extended the Bolsonaro family's presence in Congress and confirmed continuity in São Paulo. Carlos Bolsonaro and Michelle Bolsonaro each won seats in the Senate, while Jair Renan was elected to the lower house. In São Paulo, Tarcísio de Freitas was reelected governor.
The runoff pairs two political lineages now defined in opposition to each other. Former president Jair Bolsonaro is serving a 27-year sentence for plotting a failed coup after losing the 2022 election to Lula. Lula was elected president in 2002, 2006 and 2022 and is seeking a fourth non-consecutive term in 2026.
Polling immediately before the vote pointed to a close runoff. An Oct. 1 Datafolha simulated second round put Lula at 48% and Flávio Bolsonaro at 45% Reuters. Lula closed his first-round campaign with a march through São Paulo that drew large crowds of supporters Reuters.
The broader context here is succession under constraint. A movement still identified with a jailed former president has transferred its presidential candidacy to his eldest son, and that candidacy finished first in October. For specialists, the question is less about name recognition than about transferability: whether congressional strength, state-level incumbency and a near-majority in the first round translate into a runoff majority without the former president on the ballot.
Looking at what this means for the next three weeks, the arithmetic is tight and the coalitions are narrow. A 2.5-point lead reverses the pre-election polling order but stays within a range where endorsements from eliminated candidates, turnout operations and regional machines matter more than national messaging. Brazil elects a president with continental weight on trade, climate and multilateral alignment. The choice on 25 October will clarify not only who governs, but which political project can assemble a majority in a polarized electorate.
