Recent polling for Brazil’s October 4 first-round presidential vote shows incumbent Luiz Inácio Lula da Silva leading Flávio Bolsonaro by roughly 5–7 points, with Lula near 38–40% and Bolsonaro near 31–34%. This narrow gap, amid a fragmented field where other candidates poll in the low single digits, has positioned a Lula da Silva 5–10% margin as the leading outcome in trader assessments. Flávio Bolsonaro’s support has been tempered by June audio recordings and a subsequent family dispute with Michelle Bolsonaro that drew media attention, though the pair reconciled by late July. Lula’s edge reflects his incumbency advantages and targeted economic measures, while the overall contest remains sensitive to turnout among swing and independent voters in the weeks ahead.

This market will resolve according to the margin of victory between the top two candidates in the first round of the next Brazil Presidential Election.
For the purpose of this market, the “margin of victory” is defined as the absolute difference between the percentages of valid votes received by the first- and second-place candidates. Percentages of the valid votes received by each candidate will be determined by dividing the total number of valid votes each of the top two candidates receives by the sum of all valid votes cast in the election.
If the reported value falls exactly between two brackets, then this market will resolve to the higher range bracket.
This market will resolve based on the official vote count once the vote count has been made official.
If a recount is initiated before the vote total has been made official, the market will remain open until the recount is completed and the vote is made official.
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/).
