Recent polls from Datafolha, Nexus, and others show incumbent Luiz Inácio Lula da Silva leading first-round voting intentions at 39–41 percent, with Flávio Bolsonaro of the Liberal Party consistently placed second at 33–37 percent, well ahead of Ronaldo Caiado, Renan Santos, and Romeu Zema. Jair Bolsonaro remains ineligible due to a final conviction and suspended political rights, positioning his son as the primary right-wing standard-bearer after his July party convention. Official campaigning began August 16, 2026, with limited early debates and stable polling trends reinforcing trader expectations that Flávio will secure the runner-up spot on October 4 absent a major late shift among fragmented opposition candidates.
