A presidential election is scheduled to take place in Rondônia, 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 Rondônia. Candidates will be primarily ranked by order of valid votes won in Rondônia. 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/).Flavio Bolsonaro maintains a commanding position in Rondônia first-round polling due to the state's consistent conservative leanings and strong bolsonarista base, with recent local surveys showing him ahead of Lula by margins of 20 points or more. This regional dynamic, rooted in 2022 voting patterns and ongoing party organization by the PL, underpins trader consensus reflected in the elevated odds. National trends favoring Lula or rising support for candidates such as Augusto Cury have not materially altered state-level preferences to date. Late developments including shifts in turnout, endorsements, or campaign events in the weeks before the October 4 vote could still narrow the gap, though current evidence points to structural advantages for the frontrunner.
