Flávio Bolsonaro leads trader expectations for second place in Brazil’s October 4 first-round presidential election because recent polling consistently places him immediately behind incumbent Luiz Inácio Lula da Silva. Jair Bolsonaro’s December endorsement unified right-wing support behind his son, allowing Flávio to consolidate conservative voters while other candidates such as Ronaldo Caiado and Romeu Zema remain in single digits. May surveys from Quaest, Ideia, and Futura show Lula at 38–40 percent and Flávio at 33–37 percent, with the remainder fragmented. This structure leaves limited room for any other contender to overtake the senator before voting day.
