Recent polling from multiple firms, including PoderData and Nexus surveys in early-to-mid August 2026, shows President Luiz Inácio Lula da Silva leading the first round with 38–42% support ahead of the October 4 vote, while Senator Flávio Bolsonaro trails in the high 20s to mid-30s. This gap has solidified after Flávio secured the Liberal Party nomination in July with his father Jair Bolsonaro’s endorsement, consolidating much of the right-wing vote despite earlier scandals. Other declared candidates such as Renan Santos and Ronaldo Caiado remain in low single digits, limiting their prospects for second place. Traders have priced this polling hierarchy and limited fragmentation on the right into an 82% implied probability for Flávio as the second-place finisher.
