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 from mid-to-late August 2026 place incumbent President Luiz Inácio Lula da Silva at 39–41% in first-round voting intentions, with Senator Flávio Bolsonaro at 33–37% and remaining candidates such as Ronaldo Caiado, Renan Santos, and Romeu Zema in the low single digits. This distribution leaves the leading contenders well short of the absolute majority of valid votes required for an outright first-round victory on October 4. Brazil’s fragmented multi-party system and historical record of runoffs in every presidential election since 2002 reinforce the pattern. Official campaigning began only on August 16, with early debates producing no evident consolidation among major contenders, sustaining trader consensus that a second round on October 25 remains the probable outcome.
