**Flavio Bolsonaro holds a strong 83.5% implied probability of finishing first in Amapá during the October 25 presidential runoff against Lula.** This trader consensus stems from the national momentum Flavio gained after leading the first round with roughly 47% of valid votes nationwide, contrasted with Lula’s 45%. In Amapá itself, the October 4 first-round result was an extremely tight contest, with Lula edging ahead by just 225 votes (45.71% to 45.67%). Pre-runoff polling had shown Flavio competitive or slightly ahead in second-turn simulations, supported by stronger backing among men and evangelical voters in the state. The upcoming runoff timeline, combined with Flavio’s broader state-level gains and the right’s organizational edge in key Northern demographics, underpins the current market positioning, while Lula’s narrow first-round hold reflects residual local support that traders view as unlikely to expand sufficiently.
