Presidential elections are scheduled to be held in Brazil on October 4, 2026. A second round will be held if no candidate secures more than 50% of the valid votes in the first round. This market will resolve to "Yes" if any candidate wins this election in the first round. Otherwise, this market will resolve to "No". If the result of the first round of this election isn't known by June 30, 2027, 11:59 PM ET, the market will resolve to "No". 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/).Recent August 2026 polls show incumbent Luiz Inácio Lula da Silva leading with 40–44% of first-round voting intentions, followed by Flávio Bolsonaro at 28–40% and a fragmented field of right-wing candidates—including Ronaldo Caiado, Romeu Zema, and Renan Santos—each in single digits. No contender approaches the 50% threshold required for outright victory under Brazil’s two-round system. The October 4 first-round date is weeks away, yet vote splitting on the right and persistent undecided or null ballots continue to cap front-runner support well below historical levels needed for a first-round win. Every presidential contest since 2002 has advanced to a runoff, a pattern reinforced by current polling averages and the absence of late-campaign consolidation or major endorsements that would alter the field. Trader consensus at 91% for no outright winner reflects this durable fragmentation and structural precedent.
