Market Discussion
Early indications and prediction markets suggest Keiko Fujimori is leading the first round of the Peruvian presidential election, with some forecasts placing her margin of victory between 5% and 10% (inclusive of 5%, exclusive of 10%) [1]. A specific market for this outcome shows a 92% probability [1]. With 73% of ballots counted, Fujimori had secured nearly 17% of the votes [2], positioning her for a likely runoff election as no candidate is projected to reach the 50% threshold required to win outright [3]; prediction markets indicate a 98% probability of a runoff [4].
