Overview

• Official results show the Peronist Fuerza Patria coalition at roughly 47% versus about 34% for La Libertad Avanza, with turnout near 63–65% in Argentina’s largest province.
• President Javier Milei conceded a “clear defeat,” admitted unspecified mistakes, and pledged to deepen and accelerate his libertarian reform agenda.
• Markets slid after the vote, with Buenos Aires’ main stock index down around 12%, the wholesale peso off about 5%, and over-the-counter bonds lower by roughly 4%.
• The contest followed a bribery scandal involving Milei’s sister linked to the National Disability Agency and a rare congressional override of his veto on disability allowances.
• Analysts warn the result complicates efforts to grow Milei’s minority in Congress before the Oct. 26 midterms, reinforcing calls for alliance-building in a province that holds about 40% of voters and over 30% of GDP.
