## About

A presidential election is scheduled to take place in Brazil on October 4, 2026.

This market will resolve according to the official voter turnout rate in the first round of the specified election, defined as the total number of votes cast divided by the total number of eligible voters (see 2022 example: https://sig.tse.jus.br/ords/dwapr/r/seai/sig-eleicao-resultados/home-comparecimento-votacao?p0_ano=2022).

If the reported value falls exactly between two brackets, this market will resolve to the higher bracket.

If the results of this election are not known by June 30, 2027, 11:59 PM ET, this market will resolve to the lowest bracket.

The resolution source for this market will be official information published by the Brazilian government, specifically the Superior Electoral Court (Tribunal Superior Eleitoral, TSE) (e.g., https://dadosabertos.tse.jus.br/).
