Flávio Bolsonaro's commanding position in trader pricing for first place in Paraná during the October 25 second round stems from his decisive first-round performance in the state, where he captured nearly 60% of valid votes against Lula's 31%. Multiple September polls had already shown the PL candidate leading by 15–20 points or more in both first-round and head-to-head scenarios among paranaense voters, reflecting entrenched regional preferences and Lula's elevated rejection levels there. Local alliances, including with the newly elected governor Sergio Moro, further reinforced this positioning. While the market implies limited room for reversal, late shifts in turnout, national campaign developments, or unforeseen events between now and the runoff remain the primary variables that could narrow the gap.
