Eduardo Riedel, the incumbent governor seeking re-election under the PP banner with a broad center-right coalition, maintains a commanding lead in recent polling for the October 4 first-round vote in Mato Grosso do Sul. Surveys from late August and early September, including AtlasIntel, show him at 49% of voting intentions—sufficient in some estimates to secure an outright win—while main challenger Fábio Trad (PT) trails at 26% and João Henrique Catan (Novo) at around 12%. This positioning reflects Riedel's established administrative record, approval ratings near 51%, and fragmented opposition. Traders price him at 97.1% as the consensus outcome, though a narrow path remains for shifts from undecided voters or unexpected late developments before the October runoff window if needed.
