Javier Milei holds the leading position in the 2027 Argentine presidential race as incumbent, with La Libertad Avanza ahead in recent party-preference surveys despite approval ratings stuck near 35-42% and disapproval exceeding 55% in multiple September measurements. Economic headwinds and declining government confidence have narrowed his edge, yet traders price his continuity prospects highest. Axel Kicillof emerges as the primary challenger, topping positive-image rankings among Peronist figures and posting competitive showings in hypothetical first-round and runoff matchups that often fall within polling margins. Other listed candidates trail with limited demonstrated national support, aligning with the market's emphasis on the Milei-Kicillof dynamic one year before voting.
