**Lula da Silva and Flávio Bolsonaro lead first-round polling and are widely viewed by traders as the near-certain runoff qualifiers ahead of Brazil’s October 4 vote.** Recent August surveys place Lula in the high 30s to low 40s percent, with Flávio in the low-to-mid 30s, while Renan Santos, Ronaldo Caiado, and Romeu Zema remain in single digits amid a fragmented field. The incumbent’s position is supported by expanded debt-relief measures and temporary fuel subsidies, which have helped stabilize assessments of his standing. Flávio has consolidated much of the right-wing vote following Jair Bolsonaro’s ineligibility, though earlier audio leaks and family tensions produced temporary setbacks before a public reconciliation. With candidate registration closing around mid-August and the official campaign period beginning immediately afterward, attention now shifts to how the polarized contest and any late shifts in independent or regional support could affect the final first-round margins. A runoff on October 25 appears highly likely given current polling averages.
