Recent polling consistently places Luiz Inácio Lula da Silva first in first-round vote intention at 38–42 percent, with Flávio Bolsonaro of the Liberal Party a clear second at 28–35 percent and all other declared candidates—including Ronaldo Caiado, Renan Santos, and Romeu Zema—in low single digits. Flávio’s position stems from unified support within the PL and broader right-wing electorate, reinforced by his July 2026 party nomination and endorsement from his father, the ineligible former president. Other right-leaning contenders remain fragmented and lack comparable national name recognition or organizational backing. Recent Datafolha and Quaest surveys conducted after the official campaign launch show the gap between the top two narrowing modestly yet remaining stable, with no late shifts elevating secondary names. Traders therefore price Flávio Bolsonaro as the near-certain second-place finisher on October 4.
