Mailza Assis, the incumbent governor who assumed office in April 2026 after her predecessor resigned to run for Senate, secured 49.76% of valid votes in the October 4 first round and advances to the October 25 runoff against Senator Alan Rick, who received 32.27%. Her performance reflects the strength of the Avança Acre coalition, incumbency resources, and a fragmented opposition field that included Tião Bocalom, Thor Dantas, and minor candidates. Traders assign her a commanding implied probability consistent with this first-round margin and historical runoff dynamics favoring frontrunners with near-majority support. A decisive shift could occur only if Rick consolidates the remaining first-round votes, turnout patterns change markedly, or late campaign developments alter voter preferences in the final weeks.
