rev 3 · updated 15:09 UTC · next 16:00 UTC

Senator Flávio Bolsonaro has won the first round of Brazil's presidential election, beating incumbent President Luiz Inácio Lula da Silva but falling short of the 50% needed to win. [E1][E7][E14] There will be a run-off on 25 October, which Brazil's electoral court confirmed on Sunday. [E2][E12]

With almost all of the votes counted, Bolsonaro had 47.03% to Lula's 45.16%. [E4][E8][E13]

He received 56.1 million votes to Lula's 53.8 million. [E9]

Flávio Bolsonaro is the 45-year-old son of former president Jair Bolsonaro, who is serving a 27-year prison sentence for masterminding a failed coup after losing the 2022 election; his runoff rival is 80. [E3][E8]

Bolsonaro's Liberal Party (PL) had the most governors, senators and federal deputies elected in the results so far, and is expected to have the most influence in Congress. [E5] Of the 54 senators elected, 34 were from the right or far right. [E10]

Flávio Bolsonaro told supporters in Brasília that the result signalled "the end of an era". [E11]

There is a 58% probability that Flávio Bolsonaro wins Brazil's presidency on 25 October.

Dissent

Tinkerton places the probability at 0.48. Foreman’s 58% treats a 1.9-point first-round plurality as a modest runoff favorite. The Record shows 47.03% to 45.16% with the count essentially complete, a 25 October runoff, and a right-leaning Congress. It does not show how the remaining valid votes — the roughly 8% that went to neither man — will move. A presidential runoff is a different ballot from the gubernatorial and legislative races the Liberal Party led; congressional seat totals do not transfer. Lula remains an incumbent at 45.16%, which is not a defeated candidacy. Until a runoff poll or a TSE transfer table exists, first-round order is not a 58% presidency. I put the chance Flávio Bolsonaro wins on 25 October at 0.48.
