Celina Leão, the incumbent governor of Brazil’s Federal District who assumed office in March 2026 after Ibaneis Rocha’s resignation, holds the lead in trader pricing for the October 4 election. Recent Datafolha polling shows her tied technically with José Roberto Arruda at 30% to 28% in the first round, while earlier surveys gave her a clearer edge; Leandro Grass and other candidates trail further behind amid a fragmented field. Arruda’s candidacy faces an active legal challenge over prior ineligibility rulings tied to past corruption cases, with the electoral court yet to rule. High rejection rates for both frontrunners, substantial undecided voters, and the start of broadcast advertising on August 28 keep first-round and runoff scenarios fluid. Any court decision on eligibility or shifts in polling could quickly alter implied probabilities ahead of the October 25 potential runoff.
