As of 11 October 2026, Brazil's presidential election is headed to a 25 October runoff between Flávio Bolsonaro and President Luiz Inácio Lula da Silva. Brazil's electoral court reported 47.03% of valid first-round votes for Bolsonaro and 45.16% for Lula.
What is known.
The first-round lead is a recorded result, not a declaration of the eventual winner. The forecast will be settled by the Superior Electoral Court's official runoff result for the Bolsonaro–Alfredo Gaspar ticket.
Why it is a possibility.
Bolsonaro starts the second round slightly ahead, giving him a plausible route to victory. The gap is small enough that voters who backed eliminated candidates could change the result, so the editorial probability stays close to an even chance.
What could prevent it.
Supporters of eliminated candidates may consolidate behind Lula in the runoff.
How it will be assessed.
Resolves yes if Brazil's Superior Electoral Court declares the Flávio Bolsonaro–Alfredo Gaspar ticket elected in the 25 October 2026 presidential runoff.
