This market will resolve according to the listed candidate that wins this election.
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/).The Brazilian presidential race ahead of the October 2026 first round remains tightly contested, with incumbent Luiz Inácio Lula da Silva holding a modest lead in trader pricing over Senator Flávio Bolsonaro. Lula seeks an unprecedented fourth term amid steady approval ratings near 45 percent, while Flávio consolidates right-wing support following his father Jair Bolsonaro’s endorsement and the latter’s ongoing ineligibility after a coup-related conviction. Recent Quaest, Datafolha, and Ideia polls show the pair statistically tied in simulated runoffs at roughly 45 percent each, with a fragmented field including Romeu Zema and Ronaldo Caiado drawing single-digit shares. A May leak tying Flávio to the Banco Master banking scandal has introduced fresh scrutiny without yet shifting broad polling momentum. Economic conditions and potential candidate withdrawals continue to shape the narrow margins.
