Flávio Bolsonaro holds a commanding lead in trader consensus for Brazil’s October 25 presidential runoff after securing a first-round plurality of 47% against incumbent Luiz Inácio Lula da Silva’s 45% on October 4. Recent national surveys, including those from Datafolha, AtlasIntel, and Ipespe, show the Liberal Party senator ahead by four to six points in valid votes, consistent with consolidation of support from eliminated right-wing candidates. Historical patterns since Brazil’s return to democracy in 1985 further reinforce the position, as no first-round loser has prevailed in a subsequent round. Lula’s campaign faces headwinds from voter concerns over the economy and approval ratings near 43%, while the three-week window offers limited scope for major shifts before ballots are cast.
