Javier Milei, the incumbent running for re-election under La Libertad Avanza, leads trader consensus at 51.5% as the market reflects his 2025 midterm gains in Congress and continued pursuit of austerity and deregulation measures. Axel Kicillof trails at 40% as the leading Peronist contender, supported by coalition-building efforts among opposition factions and polls showing him competitive or ahead in some hypothetical head-to-head matchups. Milei’s approval ratings have declined to the mid-30s amid persistent inflation, eroding purchasing power, and recent corruption allegations, creating space for alternatives. Other candidates, including Sergio Massa, remain marginal at single-digit or lower probabilities, underscoring the concentrated focus on the Milei-Kicillof contest ahead of the October 2027 vote.
