Javier Milei, the incumbent president, leads trader consensus at 53% amid early 2027 election polling that places La Libertad Avanza ahead of Peronist options in most first-round scenarios, though his personal approval hovers near 35-38% positive amid ongoing economic pressures. Axel Kicillof, governor of Buenos Aires province and the leading Peronist challenger, sits at 35.5% as surveys show him competitive in hypothetical runoffs but trailing Milei by varying margins in broader fields. Lower probabilities for figures such as Sergio Massa and Myriam Bregman reflect fragmented opposition support and limited polling traction. Recent national surveys through August and early September 2026 indicate Milei’s edge narrows in runoff tests and remains sensitive to economic sentiment, with no major shifts from legislative or alliance developments yet altering the field.
