Recent national polls from early May, including surveys by Quaest, Ideia, and Futura, place incumbent Luiz Inácio Lula da Silva at 38–40 percent first-round support while Flávio Bolsonaro registers 33–37 percent, with Ronaldo Caiado, Romeu Zema, and smaller candidates dividing the remainder. This fragmented field leaves both frontrunners well short of the 50 percent plus one threshold required for an outright win on October 4. Trader consensus reflected in the 86 percent probability for no outright victory aligns with these consistent polling patterns and the structural dynamics of Brazil’s two-round presidential system, where vote consolidation typically occurs only between rounds.
