Traders price Flavio Bolsonaro at 97.7% to finish first in Acre in the Brazilian presidential election second round, driven by the state's established conservative voting patterns and consistent regional backing for candidates aligned with the Bolsonaro movement. Lula trails at 2.1%, consistent with weaker historical performance in northern states during runoffs. Other candidates remain at 50%, reflecting limited expected traction in Acre's electoral math. Late national developments, such as shifts in coalition support, turnout surges in key municipalities, or unforeseen legal or health events affecting leading contenders, represent the main scenarios that could still alter the outcome before polls close.
