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.
