Recent polls from mid-March 2026, including AtlasIntel (18-23 March) showing Luiz Inácio Lula da Silva at 46% and Flávio Bolsonaro at 40% in first-round scenarios, alongside Quaest and Datafolha surveys placing Flávio consistently second behind Lula at 32-42%, drive trader consensus favoring Flávio Bolsonaro for second place ahead of the October 4 first round. Lula leads most multi-candidate fields by 5-7 points amid high undecided rates (10-21%), but Flávio's surge—closing a 12-point gap from February polls—reflects his consolidation of right-wing support following Jair Bolsonaro's ineligibility and Ratinho Júnior's withdrawal on March 23. Lower odds for Tarcísio de Freitas, Fernando Haddad, and others align with their single-digit showings, underscoring a tight Lula-Flávio duel shaping market positioning.
