Flávio Bolsonaro holds a commanding position in trader pricing for first place in Rondônia during Brazil’s October 25 presidential runoff, reflecting the state’s established conservative leanings and his decisive 67.5% first-round showing against Lula’s 25.9%. Pre-election surveys consistently showed double-digit leads for the PL candidate in the northern state, where voters have backed right-leaning platforms on land regularization, security, and federal policies in recent cycles. Local PL victories for governor and Senate seats further align with this pattern. The market’s near-certainty pricing incorporates these structural advantages while leaving room for shifts from unusually high opposition turnout, national campaign developments in the final weeks, or unforeseen events that could narrow margins in this Amazonian electorate.
