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 polling aggregates for Brazil’s October 4 first round show incumbent President Luiz Inácio Lula da Silva leading with roughly 39–41% support, followed by Flávio Bolsonaro at 33–34% and smaller candidates each in the low single digits. This distribution leaves the top contender well short of the 50%+1 threshold required for an outright victory under Brazilian electoral rules. The field remains fragmented, with no evident consolidation or late surge that would push any single candidate above majority support. Historical patterns in polarized Brazilian presidential contests have likewise favored runoffs, reinforcing trader consensus that a first-round decision is unlikely absent a dramatic shift in the final weeks.
