Brazil's general election: first round October 4, 2026, and a presidential runoff on October 25 between Lula and Senator Flávio Bolsonaro.
See it on the Geopolitics map →The picture
About 155 million registered voters, most required by law to vote, use electronic machines. The first round chose Congress and many governors but no president. Lula, 80, of the left-wing Workers' Party, seeks a fourth term against Senator Flávio Bolsonaro of the right-wing Liberal Party, eldest son of Jair Bolsonaro, jailed after a 2025 conviction for plotting to overturn the 2022 election, which he denies. Lula runs on social programs and sovereignty; Flávio on crime, lower spending, amnesty for his father, ties to Trump.
Why it matters
It sets the direction of Latin America's largest economy: Lula's state-led, nonaligned path or a right-wing turn toward Washington, with stakes for budgets, the Amazon and BRICS.
Key facts and numbers
Official results come from the Superior Electoral Court (TSE), which counts electronic votes within hours; polls by firms such as Datafolha and Quaest track the race.
What to watch
Outlook: the runoff result itself, whether the loser accepts it peacefully after the January 2023 riots in Brasília, and how Congress lines up either way.

▸Brazil's 2026 presidential election will choose the next leader of BrazilFact
The relationship
The vote picks the president, the Chamber of Deputies, two-thirds of the Senate and state governors for 2027–30. Its outcome sets Brazil's fiscal path, Amazon policy and alignment between the US and China, all of which move the real and Brazilian assets.
Since when and why
Nationwide; first round October 4, 2026, presidential runoff October 25, 2026; about 155 million registered voters.
How we know
Fixed by Brazil's constitution and electoral calendar; official results come from the Superior Electoral Court (TSE).
What to watch
How much markets have priced in either outcome, and whether a polarized result brings gridlock between the president and Congress, are open questions.
▸Brazil's 2026 presidential election will decide whether to re-elect Luiz Inácio Lula da SilvaOutlook
The relationship
The runoff decides whether Lula, already the only person elected Brazil's president three times, wins an unprecedented fourth term, which would end in early 2031 when he is 85, or hands power to the Bolsonaro movement he defeated in 2022.
Since when and why
Runoff October 25, 2026, after the October 4 first round; Lula faces Senator Flávio Bolsonaro of the Liberal Party.
How solid?
Outlook: the result is unknown until the TSE counts the runoff votes; polls by firms such as Datafolha and Quaest suggest but do not settle it.
What to watch
How much his age and health weigh on voters, and who would lead Brazil's left after him, are open questions.
