Lula’s campaign has declined participation in the initial August 23 presidential debate organized by Bandeirantes and partner outlets, citing format concerns and the presence of lower-polling candidates, while Flávio Bolsonaro’s camp has signaled a matching absence. This leaves the frontrunners out of the first televised matchup ahead of the October 4 first round. Multiple later debates remain scheduled for September 14 and 27, providing additional opportunities before the October 3 cutoff. Lula’s consistent polling lead over Bolsonaro and other challengers supports a selective approach focused on controlled appearances. Traders price the 58.5% implied probability for Yes on the balance between the confirmed early absence and the remaining pre-first-round slots still available.
