A presidential election is scheduled to take place in Rio de Janeiro, 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 from Rio de Janeiro. Candidates will be primarily ranked by order of valid votes won in Rio de Janeiro. 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/).Flávio Bolsonaro holds a commanding position in trader assessments for first place in Rio de Janeiro’s October 2026 presidential first round, reflecting his status as the state’s sitting senator and the Liberal Party nominee with deep local roots in Bolsonarismo. Recent state-specific polling from Datafolha and Quaest shows him leading or statistically tied with incumbent President Lula, consistent with his home-state advantage and stronger rejection ratings for Lula among fluminense voters. Minor candidates including Renan Santos, Ronaldo Caiado, Romeu Zema, and Augusto Cury register only low-single-digit support, while others remain at negligible levels. With the first-round vote less than six weeks away, traders appear to price in limited scope for late shifts absent major developments in the remaining campaign window.
