Flávio Bolsonaro beat Lula 47.1% to 45.1% in Brazil's first round — a shock the final polls missed by miles. Runoff: October 25.

RIO DE JANEIRO — Brazil's pollsters got it wrong, and Brazil's president got the shock of his career. With nearly all ballots counted late Sunday, right-wing Senator Flávio Bolsonaro — the 45-year-old eldest son of imprisoned former president Jair Bolsonaro — finished first in the presidential first round with 47.06 percent of valid votes, 56,075,582 ballots, ahead of incumbent Luiz Inácio Lula da Silva at roughly 45 percent. The margin was about 2.3 million votes, but neither man cleared the 50-percent threshold of valid votes, so the two will meet again in a runoff on October 25. The final polls had forecast a Lula lead of about three points. Instead, the senator's camp celebrated what he called the end of the PT era — and political scientist Oliver Stuenkel's verdict hung over the night: “Flávio Bolsonaro is now the clear favourite to be Brazil's next president.”
The numbers landed early and refused to move. With 99.88 percent of the vote counted, the Superior Electoral Court’s tally gave Bolsonaro 56,075,582 votes against Lula’s 53,778,788 — a gap of roughly 2.3 million in an electorate of more than 150 million. The eleven other candidates in the twelve-strong field were left with the crumbs: none cleared 3 percent, and the third, fourth and fifth finishers were all right-wing — a single-digit pool of votes likely to flow the senator’s way on October 25.
The pollsters called it a tie. The machines called it a Bolsonaro.
The misses were not close. Datafolha’s eve-of-vote survey had Bolsonaro at 42 percent against Lula’s 45; the final CNT/MDA poll was worse still, Lula 43.1 to Bolsonaro 38.0, with a simulated runoff nearly tied. The ballot boxes delivered something else entirely: a first-round lead for the challenger of roughly two points. “The pollsters missed badly,” Robert Muggah, co-founder of the Igarapé Institute think tank, told Reuters, adding: “Expect the runoff polls, which show a dead heat, to understate Bolsonaro as well.” Brazilian pollsters similarly underestimated Jair Bolsonaro in 2018 and 2022 — but never by a margin this wide, or in the wrong direction for the favorite.
The senator overran his supposed ceiling in the country’s biggest states. In São Paulo, the largest, he led Lula 52 percent to 38; in Minas Gerais, the historic bellwether, 50 to 43; in his Rio de Janeiro stronghold, 53 to 39. It was the kind of night that turns on individual defections: Oscarina de Oliveira, a 62-year-old caregiver, told Agence France-Presse she had always voted Lula — “when I got there, I switched to Bolsonaro. Just to see what happens, to see if anything changes.” A country exhausted by polarization voted with its exasperation.
Flávio Bolsonaro savored it. Speaking to supporters, the 45-year-old senator — little known nationally only months ago, when his father anointed him as heir — called his first-place finish “the end of the PT era,” a reference to Lula’s Workers’ Party, and said he “can’t wait to regain democracy in three weeks.” He repeated the proposal that has become his signature: ending presidential re-election altogether. “I only need one term.” It was a striking line from a dynasty’s heir — and a taunt aimed squarely at an 80-year-old seeking a fourth term.
Lula’s answer came from a hotel in São Paulo, hoarse and unsparing toward himself. “I confess I was convinced I would win the election in the first round,” he told party workers. “Starting tomorrow, we begin a new campaign.” He had also warned, earlier, that his rival was an “uncertainty for Brazil,” and called the runoff “the ultimate test” for the country. The Wall Street Journal reported him calling the night a “lesson in democracy” — the line of a man who has lost before, in 1989, 1994 and 1998, and won four national campaigns after that.
The presidency was only the headliner. Conservatives piled up gains in both houses of Congress — particularly the Senate, where a stronger right-wing bloc would make life easier for a President Bolsonaro and harder for a re-elected Lula. The Bolsonaro family itself swept: Jair Bolsonaro’s wife Michelle and his son Carlos won Senate seats, while his youngest son Jair Renan and his brother Renato took seats in the lower house. Several governorships went the same way. Lula, the sole progressive in the race, faces a runoff with nowhere natural to grow — while the senator inherits the right-wing also-rans’ voters, a combined pool of roughly five to seven percent.
Geopolitics. This is the Latin American right’s biggest prize, and Washington’s fingerprints are on the campaign. Flávio Bolsonaro runs as an ally of Donald Trump, and a victory would extend the wave of Trump-aligned right-wing wins across the region — while a Lula re-election “could be a challenge for Washington,” Reuters noted, after years of clashes over trade and security. Brian Winter, editor-in-chief of Americas Quarterly, told CNN the runoff offers “two competing visions of what the country should look like and what Latin America should look like.” The tariff war between Brasília and Washington is now, effectively, on the ballot.
Macroeconomics. The markets voted before the people did. Brazil’s currency and stock market have been rising on the prospect of a business-friendly challenger, Reuters reported — and Sunday’s surprise is likely to extend that rally. Yet both campaigns offered, in Reuters’s words, “meager policy debate”: both men skipped the major television debates, Lula defends a state with expanded social spending, Flávio promises Milei-style austerity. The winner inherits slowing growth and strained public finances — and three weeks in which the economy is a slogan, not a plan.
Demographics. The Wall Street Journal’s diagnosis of the right’s surge — fury at violent street crime, the political muscle of evangelical Christians, middle-class anger at taxes and the left’s handling of the economy — is a portrait of an electorate voting against something as much as for someone. Voting is compulsory for most adults, and turnout runs among the highest in the Americas; the exasperated middle showed up. “Few voted with conviction,” Agence France-Presse observed of a nation “jaded by familiar choices.” In a compulsory-vote democracy, fatigue itself becomes a constituency.
Historical patterns. History has a warning for Lula: since Brazil’s return to democracy in 1989, every first-round winner has gone on to win the runoff. It is the statistic the PT’s strategists will stare at for three weeks. And there is a nearer ghost: this is, in many ways, the 2022 rerun — except the name on the ballot is the son’s, the polls were wrong in the opposite direction, and the incumbent is the one trailing. Stuenkel’s line — “It is very hard to imagine Lula turning this around” — is the consensus of the history books, if not yet of the voters.
Structural and technological. Two structural facts shaped the night. First, both frontrunners skipped the major TV debates, and the campaign was fought in soundbites, rallies and networks — a reminder that in Brazil’s media system, the candidate who owns the direct channel owns the narrative. Second, the polling industry faces a credibility crisis: after 2018 and 2022, a third straight undercount of the right, this time the largest, will fuel the Bolsonaro camp’s long-standing claim of pollster bias — and poison every survey published before October 25.
Three weeks, and no rest. The runoff campaign begins Monday with the arithmetic brutal for the incumbent: the senator needs only a fraction of the eliminated right-wing vote to cross 50 percent, while Lula must win over the centre and the undecided — and persuade a country that rejected his fourth term by 2.3 million votes to reconsider. Early Sunday, Bolsonaro told journalists he was counting on “a protest vote from people who would otherwise vote for another candidate but are opposed to Lula.” Whether the result is accepted will matter as much as the result itself: Brazil has never produced a gracious loser in the polarized era, and a tight finish on October 25 would test its institutions to the limit. Until then, the only poll that matters is the one the machines already took.
Western newsrooms read the night as a polling catastrophe first and a political earthquake second. The through-line from CNN to the Wall Street Journal is the scale of the miss: a three-point Lula lead in the final surveys turned into a two-point Bolsonaro win at the ballot box, the third straight undercount of the Brazilian right, and the largest yet. The frame is institutional — what it means for the credibility of pollsters, for market expectations on Monday morning, and for a Washington that must now game out a Trump-aligned presidency in the hemisphere's largest economy.
The second Western reading is dynastic. A 45-year-old senator, obscure nationally until his imprisoned father anointed him, has inherited not just a name but a movement — and the family swept the down-ballot races alongside him. The question Western analysts now ask is whether bolsonarismo has become transferable: a brand that survives its founder's 27-year sentence and wins without him on the stump.
The Eastern reading is colder and more transactional: this is about the map of Latin America, not the drama of one family. A Bolsonaro victory on October 25 would put the region's largest economy in the camp of Washington's tariff diplomacy — a realignment Beijing has every reason to dread and Moscow every reason to watch. The vote is compulsory, the machines are electronic, the count was fast: for capitals that prize order over theater, Brazil just demonstrated that power can change hands without a shot fired, even in a polarized giant.
The second Eastern note is on information. Both frontrunners skipped the televised debates and campaigned through direct channels; the polls were wrong by miles. For states that manage their own information environments tightly, the lesson is double-edged: direct-to-voter media beats legacy gatekeepers, but it also blinds the forecasters — nobody, including the pollsters, knew what was coming.
The Global South reading starts at home: Brazil is the South's heavyweight, and its choice reorganizes the room. A Lula defeat would remove the most prominent voice of the Global South's institutional left from the world's stage — the man of BRICS expansion, of South-South credit lines, of the Amazon as a planetary bargaining chip. A Bolsonaro win hands the steering wheel to a leader promising alignment with Washington and austerity at home, and every capital from Buenos Aires to New Delhi is recalculating what that changes for BRICS, trade and climate.
The second Southern reading is about dignity and fatigue. Agence France-Presse's caregiver who “switched to Bolsonaro, just to see what happens” is the South's perennial voter: not ideological, but exhausted — by prices, by crime, by familiar faces. Compulsory voting dragged that exhaustion to the ballot box. The lesson travels: in the South, incumbents do not lose to ideas; they lose to weariness.
The final surveys were not merely off but inverted: CNT/MDA's last poll had Lula ahead 43.1 to 38.0, Datafolha's eve-of-vote survey 45 to 42 — the ballot boxes gave Bolsonaro a roughly two-point lead. Robert Muggah of the Igarapé Institute told Reuters “the pollsters missed badly” and warned runoff surveys showing a dead heat may understate Bolsonaro too. Brazilian pollsters also underestimated Jair Bolsonaro in 2018 and 2022, but never by this much.
He called his first-place finish “the end of the PT era,” a reference to Lula's Workers' Party, said he “can't wait to regain democracy in three weeks,” and repeated his signature proposal: ending presidential re-election — “I only need one term.” The Times also reported him promising a “modern government” to mark the end of Lula's party.
“I confess I was convinced I would win the election in the first round,” he told party workers in São Paulo. “Starting tomorrow, we begin a new campaign.” The Wall Street Journal reported him calling the night a “lesson in democracy,” and The Times quoted him calling the runoff “the ultimate test” for the country and his rival an “uncertainty for Brazil.”
The third, fourth and fifth finishers were all right-wing, holding a combined five to seven percent of the vote — a natural pool for the senator. Lula ran as the race's sole progressive, which limits his room to grow. Early Sunday, Bolsonaro said he was counting on “a protest vote from people who would otherwise vote for another candidate but are opposed to Lula,” according to Reuters.
Conservatives made significant gains in both houses, particularly the Senate — a stronger base for a President Bolsonaro, a harder one for a re-elected Lula. The Bolsonaro family swept its own races: Michelle Bolsonaro and son Carlos won Senate seats, youngest son Jair Renan and brother Renato took lower-house seats. Several governorships went right as well.
History says it is very hard: since Brazil's 1989 redemocratization, every first-round winner has won the runoff. But Lula has three weeks, a “new campaign,” and a career built on comebacks — he lost three presidential races before winning four. He must win the centre and the undecided while the senator needs only a fraction of the eliminated right-wing vote to cross 50 percent.
