Recent polls for Brazil's October 4, 2026 presidential election first round consistently show incumbent President Luiz Inácio Lula da Silva leading with 37–47% support, positioning Senator Flávio Bolsonaro as the clear runner-up at 32–40%, which anchors trader consensus at 65.5% odds for his second-place finish amid fragmented opposition. The latest AtlasIntel survey (April 22–27) narrowed Lula's lead to 6.9 points, with Renan Santos third at 5.3%, while April polls from Nexus, Quaest, Datafolha, and Futura reinforced Flávio's consolidation of the right-wing vote post-father Jair Bolsonaro's ineligibility. Lula's 19.5% second-place odds reflect tightening trends and 8–19% undecideds that could enable a Flávio surge, though no candidate nears the 50%+1 threshold for outright victory. High volatility persists ahead of campaign formalization.
