Brazilian President Luiz Inácio Lula da Silva secured an unprecedented fourth term on Sunday, October 25, 2026, defeating Senator Flávio Bolsonaro in a runoff election with more than 51% of the vote. The victory blocks a right-wing return to the presidency and keeps Latin America’s largest nation anchored to the left.
The veteran leftist secured 51.78% of the popular vote—equivalent to 64,248,884 ballots—while his challenger, Senator Flávio Bolsonaro, finished with 48.22% and 59,822,138 votes, according to data reported from the Superior Electoral Court. Luiz Inácio Lula da Silva won a fourth presidential mandate in a dramatic runoff that defied pre-election polls, predictive markets, and a conservative wave across Latin America.
The outcome marks the first time since Brazil’s return to democracy in the 1980s that a candidate trailing in the first round has mounted a successful comeback to win the presidency.
Lula’s win deprives U.S. President Donald Trump of a key partner in a region where several governments have aligned with Washington on security and migration agendas.
During the race, Lula repeatedly framed the contest around national sovereignty, declaring that Brazil is no one's backyard
while accusing his opponent of seeking to govern alongside American interests.
Flávio Bolsonaro Rejects the Vote
Flávio Bolsonaro refused to concede defeat and announced plans to challenge the legitimacy of the vote.
Standing before reporters, the senator condemned the process as an unacceptable manipulation and argued that too many questions remained unanswered following voting irregularities.
It is impossible to recognize the elections, Flávio Bolsonaro said according to France24.
The incumbent president’s team alleged that voters were prevented from voting, describing the transit shortages as an abominable attempt to block access to the polls. The dispute centered partly on a Supreme Court decision that extended voting hours by two hours in certain regions after Lula’s campaign filed complaints regarding public transit disruptions.
Markets React to the Results
Prior to the runoff, prediction markets heavily favored Flávio Bolsonaro, with platforms attributing 80% chance of victory to him on Sunday afternoon.
The election result caught financial markets and speculative platforms off guard. Traditional pollsters had also indicated a tight race leaning toward the conservative challenger.
Perpetual contracts linked to the EWZ iShares MSCI Brazil exchange-traded fund plunged more than 22% on trading platforms, reflecting investor anxiety over the continuation of state-led economic models and future fiscal policy under a fourth Workers’ Party administration. As the count flipped in Lula’s favor during Sunday evening’s tally, investor sentiment turned sharply.
Congress Faces the New Term
Three weeks prior to the presidential runoff, Brazil elected its most conservative Congress since the return to democracy in the 1980s. Lula assumes his new term facing a challenging legislative reality.
The Liberal Party and allied conservative factions secured comfortable majorities, controlling over 280 seats in the lower house and up to 50 seats in the Senate.
Oliver Stuenkel told Huffpost that he is likely to be a lame duck from the start.
International relations experts warn that the incoming legislature will likely deepen a trend of executive power ceding to Congress.
Lula campaigned on expanded social programs.
He campaigned on the revaluation of the Bolsa Família welfare initiative.
Economic pressures compound these political obstacles, but the incoming conservative Congress is expected to push for business-friendly structural reforms and spending cuts.
Lula will be sworn into office on January 5, 2027, becoming Brazil’s oldest president since the nation’s democratic transition at age 80.
