Brazil Heads to a Runoff: Flavio Bolsonaro vs. Lula on 25 October

Brazil will choose its president in a runoff on 25 October 2026 between Flávio Bolsonaro (PL) and Luiz Inácio Lula da Silva (PT).

The Superior Electoral Tribunal confirmed the pairing on 5 October. It reported 56,104,268 votes for Flávio Bolsonaro, or 47.03% of valid votes, and 53,876,617 votes for Lula, or 45.16% TSE. The gap was under two points. In Brazil a candidate needs more than half of valid votes to win outright in round one, so neither cleared that bar.

Flávio Bolsonaro is a right-wing senator and the son of former president Jair Bolsonaro. He beat what opinion polls had suggested and finished first. He is described as an ally of U.S. President Donald Trump. Jair Bolsonaro served as president from 2018 to 2022. Lula is the incumbent president and is on the left. He will turn 81 two days after the 25 October runoff.

The final tally was closer than the early count. With almost 65% counted, Flávio Bolsonaro had 49.8% and Lula had 42.25%. Candidates other than the top two were in single digits at that stage.

Lula and Flávio Bolsonaro closed their campaigns on Saturday before Sunday's first-round vote. Brazilian assets rallied on Monday, 5 October 2026, after Bolsonaro led the vote Reuters.

Evangelical Christians now make up nearly a third of Brazil's population The Guardian. Televangelist Silas Malafaia is a megachurch leader allied with Jair Bolsonaro. Thomas Traumann served as spokesperson for former president Dilma Rousseff in the broader Workers' Party orbit.

On ties with Washington, Trump designated Rio's Red Command and São Paulo's PCC as foreign terrorist organizations. That label gives U.S. authorities a counterterrorism framework for the two criminal organizations rooted in Rio de Janeiro and São Paulo.

Down-ballot races were also settled or narrowed. Jerônimo Rodrigues (PT) was reelected governor of Bahia in the first round with 4,626,265 votes, or 55.80% of valid votes. In Acre, Mailza Assis (PP) and Alan Rick (Republicanos) won the most votes in the first round and will contest the second round for governor.

The broader context here is a runoff between a sitting presidency and a Bolsonarista succession candidacy, with polling error favoring the challenger in round one. With neither man above 50%, both depend on voters from the single-digit candidates, on managing abstention, and on regional machines such as the PT governorship in Bahia. The Bahia result and the Acre runoff are useful guides to how national coalitions perform apart from presidential coattails.

Looking at what this means for the three weeks to 25 October, economic and external factors may carry unusual weight. The market rally after round one points to investor positioning on fiscal policy, state-owned enterprises, and regulatory risk under either a continued Lula administration or a Flávio Bolsonaro presidency. At the same time, the Trump alliance and the terrorist designations for the Red Command and PCC bring security cooperation, sanctions powers, and U.S.-Brazil diplomacy into the campaign debate. The evangelical electorate, at nearly a third of the population, remains central to turnout math on both sides.
