**Flávio Bolsonaro leads the market for second place in Brazil’s October 4, 2026 first-round presidential vote at 83 percent implied probability.** Recent polls show President Lula da Silva holding a first-round lead near 40 percent, with Flávio in the low-to-mid 30s and the remaining right-wing field (Ronaldo Caiado, Renan Santos, Romeu Zema) in single digits. The Liberal Party nominee has consolidated most anti-Lula support after receiving his father’s endorsement and securing the party nomination in July, despite audio leaks and family tensions that briefly dented his numbers earlier in the summer. A fragmented opposition prevents any other challenger from mounting a credible bid for runner-up status before official campaigning begins on August 16. Traders therefore price Flávio as the near-certain second-place finisher, with Lula expected to advance to a runoff.
