Mauro Mendes (União Brasil), the former governor of Mato Grosso, leads trader consensus for first place in the state's two-seat Senate election due to consistent polling leads in late August 2026 surveys. Recent Quaest and Paraná Pesquisas data place him ahead in first-vote and combined scenarios, with Janaina Riva (MDB) as the clearest challenger and a cluster of others—including José Medeiros (PL), Pedro Taques (PSB), and Carlos Fávaro (PSD)—further behind. High undecided shares (around 25%) and voter flexibility noted in the polls underscore the still-fluid race ahead of the October 4 vote. These trends reflect Mendes' established statewide profile and early campaign positioning, which have shaped market probabilities more than any single late-breaking development.
