Recent polling from Quaest, BTG/Nexus, and Datafolha shows President Lula (PT) receiving 37-40% in the October 4 first round, statistically ahead of Senator Flávio Bolsonaro (PL) at 33-37% but with the gap narrowing sharply in recent weeks and often within margins of error. Lula's support has edged up slightly in the latest waves amid a 15% Bolsa Família increase, while undecided and blank/null voters remain near 15% combined. Other candidates including Augusto Cury trail in single digits. Traders' elevated probability on Lula exceeding 44% reflects the incumbent's historical first-round performance patterns, residual undecided consolidation potential, and the close two-candidate dynamic heading into the vote.
