Will Ronaldo Caiado finish in third place in the first round of the 2026 Brazilian presidential election?

Renan Santos leads trader consensus for third place in Brazil’s October 4 first-round presidential vote because recent national polls place the Mission Party nominee in the low single digits—often 3–5 percent—frequently ahead of or tied with other non-Bolsonaro right-wing options. His support has grown among younger voters and social-media users through an anti-establishment, pro-market message that positions him to the right of Flávio Bolsonaro while drawing from blank-ballot and abstention cohorts. Ronaldo Caiado, the PSD nominee and former Goiás governor, sits second in the market at a lower share, reflecting his stronger institutional base and agribusiness ties yet more limited recent polling momentum. The broader right remains fragmented after Jair Bolsonaro’s legal ineligibility, with Romeu Zema and others polling even lower, leaving Santos as the clearest alternative for third among traders assessing current survey trends and campaign dynamics ahead of the August 15 candidate registration deadline.
