Recent polling aggregates place incumbent Luiz Inácio Lula da Silva (PT) first in first-round voting intentions at 38–41 percent ahead of the October 4 vote, with Senator Flávio Bolsonaro (PL) consistently second at 33–37 percent and the remaining field—including Ronaldo Caiado (PSD), Renan Santos (Missão), and Augusto Cury (Avante)—fragmented below 5 percent each. This distribution has narrowed in the past month as official campaigning began in mid-August and multiple surveys registered statistical ties or near-ties in runoff simulations, yet the right-wing vote remains consolidated behind the Liberal Party nominee. Jair Bolsonaro’s prior ineligibility has channeled opposition support toward his son, while low single-digit showings for alternatives limit any realistic path for them to displace Flávio Bolsonaro for second place. Trader consensus therefore reflects the stable ordering shown in late-August surveys from Datafolha, PoderData, and Nexus.
