Javier Milei maintains the highest implied probability as the 2027 election nears because recent national surveys show his La Libertad Avanza movement leading first-round intentions at 32-37 percent amid a polarized contest with Peronism, even as his approval hovers near 36 percent and economic dissatisfaction remains elevated. Axel Kicillof follows as the strongest challenger, with polls placing him at 15-32 percent in first-round matchups and within two points of Milei in hypothetical runoffs, reflecting his stronger personal image ratings and positioning as the leading Peronist alternative. Sergio Massa trails at lower levels consistent with fragmented opposition support, while minor candidates register minimal shares. October polling from multiple firms underscores the tight ballotage dynamics and economic headwinds that shape trader assessments of reelection prospects one year out.
