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 polls reflect trader consensus pricing an 85.5% chance of no outright first-round winner in Brazil's October 4 presidential election, as no candidate polls above 47% of voting intentions despite President Lula's consistent lead. The latest AtlasIntel survey (April 22-27) shows Lula (PT) at 46.6%, Senator Flávio Bolsonaro (PL) at 39.7%, and Ronaldo Caiado (PSD) at 3.3%, with blanks, nulls, and undecideds at around 5-19% across polls like Quaest (April 9-13: Lula 37%, Flávio 32%) and Datafolha (April 7-9: Lula 39%, Flávio 35%). A fragmented field and Flávio's recent gains amid Lula's steady but sub-majority support make the 50%+ valid-vote threshold unlikely, favoring a polarized runoff on October 25 per historical precedents.
