Thesis

Starts from the market price (0.842 on 2026-10-06) and a base rate: the first-round leader has won all 7 Brazilian runoffs since 1989. We take 4.2 points off for the risk that the first-round surge overstates momentum, since late minor-candidate flows and polling bias are partly priced in already. Our language read of the candidates is a cross-check only and adds no probability.
