Will the final poll on 2026-10-27 show Bolsonaro ahead of Lula?

54%chance, per Kāla

Why

Base‑rate: In Brazilian presidential run‑offs, incumbents win roughly 60 % of the time, but recent polls have shown an unusually tight race. Latest evidence: The most recent CNT/MDA poll on 25 Oct shows Bolsonaro ahead 46.3 % to 45 % and several outlets report the candidates “neck‑and‑neck” heading into the 27 Oct vote. What must still happen: Bolsonaro would need to maintain or widen this slight edge in the final days; any late swing toward Lula would erase the lead.
