General elections are scheduled to take place in Brazil on October 4, 2026. If no candidate wins outright in the first round, the top two candidates proceed to a runoff. This market will resolve to "Yes" if the listed candidate advances to Brazil's presidential runoff election or otherwise wins outright in the first round. Otherwise, this market will resolve to "No". If the president is decided in the first round of the election but the listed candidate is not the winner or the result of this election isn't known definitively 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/).Incumbent President Luiz Inácio Lula da Silva holds a narrow lead in first-round polls at 39-40% per Datafolha and Ideia surveys from early April, with Senator Flávio Bolsonaro trailing closely at 35-37%, positioning both as frontrunners to advance to the October 25 runoff under Brazil's two-round electoral system requiring over 50% for an outright win on October 4. Flávio's recent surge stems from Ratinho Júnior's March 23 withdrawal and key endorsements consolidating right-wing support, while Lula remains stable despite economic headwinds. Hypothetical runoffs show them statistically tied within margins of error. Traders weigh upcoming party conventions, candidate registrations by mid-August, and potential shifts from undecided voters comprising 10-14%.
