Javier Milei holds the leading position in trader pricing for Argentina’s October 2027 presidential election due to his incumbency, legislative gains in the 2025 midterms, and progress on fiscal balance plus inflation reduction from prior hyperinflation levels. Recent months have seen his approval ratings stabilize near 35–40 percent after earlier declines tied to persistent monthly inflation above 3 percent, purchasing-power erosion, and government-linked corruption concerns. Axel Kicillof, governor of Buenos Aires province, trails at 40 percent amid Peronist efforts to build a broad coalition that could unify center-left and center-right factions against the incumbent. Sergio Massa and other listed contenders remain marginal because polls show limited national traction and internal party divisions. Traders appear to weigh Milei’s structural advantages and reform record against the risk that economic fatigue or a consolidated opposition could narrow the race before the vote.
