Otaviano Pivetta holds the leading trader consensus at 64.5% for the October 2026 Mato Grosso gubernatorial race, ahead of Wellington Fagundes at 34.5%, with all other registered candidates below 1%. Pivetta benefits from incumbency after assuming the governorship in March 2026 upon Mauro Mendes’s resignation, combined with recent União Brasil backing and a broad Republicanos-aligned coalition that includes his vice-governor Gisela Simona. Fagundes, the PL senator who tops recent polling averages around 27–34%, draws support from bolsonarista voters and a multi-party alliance but faces fragmentation on the right. High undecided shares (20–30%) and the first-round threshold on October 4 create volatility, while minor candidates such as Natasha Slhessarenko remain marginal in both surveys and market pricing.
