The Brazilian Federal Senate election for Rio de Janeiro is scheduled to take place on October 4, 2026. This market will resolve according to the candidate who wins the most valid votes of any candidate at the specified election. Candidates will be primarily ranked by order of valid votes won. 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 definitively known 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., www.tse.jus.br/eleicoes/resultados-eleicoes).Recent Datafolha polling from late August shows Benedita da Silva (PT) holding a modest lead in voting intentions at 15 percent for one of Rio de Janeiro’s two Senate seats, ahead of a crowded field that includes Carlos Jordy (PL) and Carlos Portinho (PL) at 8 percent each, followed by Marcelo Crivella, Pedro Paulo, and Monica Benicio near 6 percent amid more than 30 percent undecided or blank responses. Traders have priced da Silva’s first-place contract highest, reflecting her consistent edge in multiple surveys and alignment with the state ticket headed by Eduardo Paes. The race remains fragmented because voters select up to two names, elevating uncertainty around second-place positioning and leaving room for late shifts in turnout or consolidation among center-right or evangelical blocs. Upcoming campaign events and any movement in undecided voters could widen or narrow separations among the top contenders before the October 4 vote.
