Recent polling shows a statistical tie or narrow lead for Flávio Bolsonaro over incumbent Lula da Silva in valid votes ahead of the October 25 runoff, with multiple surveys placing the gap at one to four points amid high rejection rates for both candidates. This closeness, combined with first-round results where Flávio captured 47% to Lula’s 45%, has positioned narrow victory margins for Flávio and “other” outcomes as leading trader consensus. Late developments including televised debates, Lula administration approval ratings near parity, and electoral court actions over social media reach have kept probabilities fluid. Voter mobilization in swing regions and any final legal or turnout shifts within the next day could alter the narrow margin distribution reflected in current pricing.
