Mailza Assis holds a commanding position in the Acre gubernatorial race after securing 49.76% in the October 4 first round, advancing to the October 25 runoff against Alan Rick, who received 32.27%. As the sitting governor who assumed office in April 2026 following Gladson Cameli’s resignation, Assis benefits from incumbency, a broad coalition including PP, MDB, PL, and others, and victories across 19 of 22 municipalities. The substantial margin and limited remaining candidates consolidate trader consensus around her implied probability near 99%. A decisive runoff outcome could still shift if voter mobilization among first-round supporters of Tião Bocalom or Thor Dantas favors Rick or if turnout patterns change markedly, though historical runoff dynamics in Brazilian state races favor the first-round leader in similar scenarios.
