Javier Milei, the incumbent president seeking re-election, leads trader pricing for the October 2027 first-round outcome amid a fragmented field that includes multiple Peronist and opposition figures. Recent national surveys show Milei and Buenos Aires Governor Axel Kicillof running near even in hypothetical first-round matchups around 31 percent each, with high undecided shares and no candidate approaching the 45 percent threshold or 40-plus-10-point margin needed to win outright. Economic headwinds, including stalled growth and inflation trends, have contributed to Milei’s approval ratings near 35 percent and elevated rejection levels, while Kicillof consolidates the main opposition lane. Party confirmation of Milei’s candidacy and ongoing debate over PASO primary reforms add procedural uncertainty, keeping implied probabilities for alternatives competitive in a multi-candidate environment where small shifts in turnout or alliances could alter first-round positioning before the October 24 vote.
