The Brazilian Federal Senate election for Goiás 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).**Gustavo Gayer leads trader consensus for second place in Goiás’s October 4 Senate election, where voters select two senators.** Recent surveys, including Quaest (late August) and IGAPE (mid-September), show ex-first lady Gracinha Caiado (União) consistently ahead in consolidated first- and second-preference votes, while Gayer (PL) ranks second or within the margin for the remaining seat ahead of Vanderlan Cardoso (PSD), Dr. Zacharias Calil (MDB), and Gustavo Mendanha (PRD). High undecided shares above 25% and low spontaneous recognition persist, yet Gayer’s federal deputy incumbency, party backing, and stronger second-choice performance in Directa polling underpin the implied probability. No major late developments have altered this positioning in the past month, with the race remaining focused on turnout and name recognition among the 11 registered candidates.
