Omar Aziz (PSD) holds a dominant position in the Amazonas governor runoff due to his first-round performance of 40.63% against Professora Maria do Carmo (PL) at 24.49%, followed by consistent polling leads of 51-56% to 37-44% in valid votes across multiple surveys conducted between October 8-19. His prior service as governor from 2010-2014, along with endorsements such as from Senator Plínio Valério, reinforces trader consensus reflected in the 93.5% implied probability. The October 25 second round remains the decisive event, with Aziz favored in most interior municipalities while facing tighter competition in Manaus. Scenarios that could narrow the gap include shifts in undecided voters (currently 6% or less in recent polls), differential turnout, or late campaign developments before voting concludes.
