Otaviano Pivetta secured re-election as Mato Grosso governor on October 4, 2026, capturing roughly 61% of valid votes in the first round and surpassing the 50% threshold required to avoid a runoff. Having assumed the office in March 2026 after Mauro Mendes resigned to pursue a Senate seat, Pivetta campaigned on policy continuity in agriculture, infrastructure, and fiscal management, drawing broad support across all 141 municipalities. Wellington Fagundes (PL) finished second near 23%, followed by Doutora Natasha (PSD) near 15%, with remaining candidates below 1%. The commanding margin and uniform geographic strength produced the current trader consensus reflected in market pricing. Late-stage legal challenges, tabulation discrepancies, or court interventions remain the only realistic avenues that could alter final certification, though none have emerged to date.
