Recent polls show incumbent President Luiz Inácio Lula da Silva holding a narrow lead in first-round voting intentions ahead of the October 4 election, typically in the high 30s to low 40s percent, followed closely by Senator Flávio Bolsonaro in the mid-30s to low 40s. Other candidates, including Ronaldo Caiado, Romeu Zema, Renan Santos, and Augusto Cury, register in the single digits. Runoff simulations between Lula and Flávio Bolsonaro remain statistically tied or within margins of error, reflecting a polarized contest where no candidate has secured an outright majority in recent surveys. With Brazil’s electoral rules advancing only the top two if the first round produces no winner, trader focus centers on polling momentum, turnout patterns in key states, and any late shifts among undecided voters before the October 25 runoff date.
