A presidential election is scheduled to take place in Brazil on October 4, 2026. This market will resolve according to the listed candidate who receives the most valid votes in the first round of this election. Candidates will be primarily ranked by order of valid votes won. If two or more candidates are tied for any position, ties will be broken by alphabetical order of the candidates’ listed full names as they appear in this market. This market will resolve to the candidate that occupies the highest finishing position after applying this ranking. If the result of this election isn't known definitively 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/).Lula maintains a commanding lead in first-round polling averages near 39 percent, well ahead of Flávio Bolsonaro near 33 percent and Augusto Cury near 6 percent, with all other declared candidates in single digits or lower. This positioning stems from the incumbent’s established voter base, the start of official television and radio advertising in late August, and the continued fragmentation of right-leaning and centrist challengers. Recent Quaest surveys through early September confirm Lula’s first-round advantage has held steady even as second-round simulations tighten to statistical ties. Traders price Lula at 85.5 percent to finish first on October 4 because no opponent currently demonstrates a realistic path to surpassing him in the initial round, while the remaining field’s low single-digit support limits any rapid consolidation before voting.
