Trader consensus favors Ronaldo Caiado at 37% implied probability for third place in Brazil's October 4, 2026, presidential first-round vote, driven by the PSD's official nomination of the Goiás governor as its pre-candidate on March 30, positioning him to consolidate center-right support amid a fragmented field behind front-runners Luiz Inácio Lula da Silva and Flávio Bolsonaro. Renan Santos trails closely at 31.5%, boosted by his third-place showing in the March 18-23 AtlasIntel poll as the MBL/Missão outsider surging past rivals like Romeu Zema. Recent polls show third-place votes at 3-5%, with high undecideds and Ratinho Júnior's March 23 withdrawal heightening volatility; further endorsements, party mergers, or new surveys could tip the balance before campaign deadlines.
