Brazil’s electoral court expects to announce the winner of Sunday’s presidential runoff between 7:30 and 8 p.m. ET. Court president Kassio Nunes Marques said voting is going “within what was expected,” according to TV Senado, the Brazilian Senate’s TV channel and NSC Total, a news site in Santa Catarina state.
The result decides the Brazil election 2026 runoff between Luiz Inácio Lula da Silva, Brazil’s president, and Flávio Bolsonaro, senator for Rio de Janeiro and son of former president Jair Bolsonaro. The race matters for Brazilian stocks and the real, the national currency; see our Brazil runoff date page for how to follow it.
What the Court President Said
Nunes Marques spoke to reporters on election day. “Historically we set a fictional benchmark of 8:30 p.m. Brasília time, but it falls around 8:30 and 9,” he said, as quoted by O Liberal, a daily newspaper in Pará state (translated from Portuguese).
He added that “everything” is running “within what was expected,” according to O Liberal. The TSE is the court that organises Brazil’s elections, runs the electronic voting machines and announces official results.
Why the Timing Matters for Markets
Brazil counts its votes electronically, so the winner is usually known within hours of the polls closing. The court’s estimate of 7:30 to 8 p.m. ET gives investors and campaigns a window to watch.
If the race is close, the announcement could slip past that window. Nunes Marques called 8:30 p.m. Brasília time a historical benchmark.
What Prediction Markets Say
