The Brazilian Federal Senate election for Piauí is scheduled to take place on October 4, 2026. This market will resolve according to the candidate who wins the second-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 second-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 polls in Piauí's October 2026 Senate race reveal a fragmented field of roughly 18 candidates for two seats, with Ciro Nogueira (PP) often leading but Marcelo Castro (MDB) and Júlio César (PSD) locked in a tight contest for second place. An August GP1 survey placed Nogueira at 23.5 percent, Castro at 11.3 percent, and Júlio César at 7.6 percent, while earlier Data Max and Real Time Big Data releases showed Castro and Júlio César trading narrow edges or tying within margins of error. Incumbency advantages, party alliances, and local endorsements sustain momentum for the top three, yet the multi-candidate ballot and inconsistent survey results keep second-place probabilities fluid. Trader consensus assigns Nogueira 27 percent, Castro 22 percent, and Júlio César 15.8 percent for second, underscoring how shifts in turnout or late endorsements could separate the contenders before election day.
