**Flávio Bolsonaro leads the market for second place in Brazil’s October 4 first-round presidential vote because recent polling aggregates and individual surveys consistently place him well ahead of other opposition candidates while Lula maintains a clear first-round lead.** Lula (PT) registers 38–41% support across late-August polls from Datafolha, Nexus/BTG, Quaest, and others, with Flávio Bolsonaro (PL) in second at 31–37%. Ronaldo Caiado (PSD), Romeu Zema (Novo), Renan Santos (Missão), and Augusto Cury trail in single digits or lower. Flávio consolidated the right-wing electorate after his July party nomination and Jair Bolsonaro’s endorsement, while other right-leaning figures failed to build comparable momentum ahead of the formal campaign launch on August 16. Traders therefore assign overwhelming probability to Flávio finishing second, reflecting both the polarized two-bloc structure and the absence of any credible challenger able to split the non-Lula vote at scale.
