This market includes any potential second round. If the result of this election isn't known by June 30, 2027, 11:59 PM ET, the market will resolve to "Other".
This market will resolve based on the result of the election as indicated by a consensus of credible reporting. If there is ambiguity, this market will resolve based solely on the official results as reported by the Brazilian government, specifically the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) (e.g., https://dadosabertos.tse.jus.br/).Incumbent President Luiz Inácio Lula da Silva maintains a lead in trader consensus for the October 2026 election through his incumbency advantages and Workers’ Party organization, despite economic headwinds and concerns over his age. Senator Flávio Bolsonaro sits second after receiving his father Jair Bolsonaro’s endorsement last December, consolidating much of the right-wing vote in a field where Jair remains ineligible following his conviction. Recent May 2026 surveys from Quaest, Futura, and Ideia show Lula and Flávio statistically tied or narrowly separated in runoff simulations, with smaller right-wing figures such as Romeu Zema and Ronaldo Caiado drawing limited first-round support. The fragmented field and high rejection ratings for both frontrunners sustain a competitive outlook ahead of the first-round vote.
