Flávio Bolsonaro placed first in Brazil’s presidential election but fell short of an absolute majority, sending the race to a runoff on 25 October. Election authorities reported that no candidate surpassed 50 percent of the vote, the share required to win the presidency in a single round.

Bolsonaro, a national legislator from a prominent conservative political family, will now face the second-place finisher in a two-candidate contest. A first-round lead confers momentum, though runoff campaigns often turn on voters who backed candidates eliminated from the field.

Brazilian law is designed to require a majority of valid votes for the presidency. When the first ballot is fragmented, it functions as a filter, leaving the top two finishers to compete for a clearer national mandate three weeks later.

No candidate surpassed 50 percent of the vote, the threshold needed to claim the presidency in a single round.

The 25 October runoff compresses the remaining campaign into a short window for both sides to assemble broader coalitions. Regional voting patterns, turnout, and the transfer of support from candidates who did not advance are expected to shape the final result.

The next president will inherit wide authority over economic policy, public security, and Brazil’s role in regional and global affairs. For that reason, the second round is typically treated as the decisive test of the country’s political direction.
