Incumbent Javier Milei leads trader consensus at 50.5% for Argentina's October 2027 presidential election, reflecting his party's stronger congressional position after the 2025 midterms and progress on austerity measures, deregulation, and fiscal balance. His approval has declined into the mid-30s amid persistent inflation, eroded purchasing power, and government-linked corruption allegations, creating openings for challengers. Axel Kicillof trails at 40.5% as the leading Peronist alternative, backed by coalition-building efforts in Buenos Aires province and polls showing him competitive or ahead in head-to-head scenarios. Sergio Massa and remaining candidates hold single-digit shares, underscoring a fragmented field where economic outcomes and opposition unity could shift probabilities ahead of the vote.
