Bia Kicis (PL) holds an 83.7% implied probability for second place in the Federal District Senate race because recent polling shows her consolidating support as one of the two leading candidates behind Michelle Bolsonaro (PL). Datafolha's October 1 survey placed Michelle at 23%, with Bia and Leila do Vôlei (PDT) tied at 18% and Erika Kokay (PT) at 13% in combined first-and-second preferences; Bia has risen three points since late September and frequently leads second-choice responses across Quaest and Igape surveys. Ronaldo Fonseca's withdrawal from the race and reported alignment with Bia further narrows the field. With voting set for October 4 and two seats at stake, traders view Bia's trajectory and party coattails as the dominant factors positioning her ahead of lower-probability alternatives such as Leila (12%) and Michelle (1.6%).
