It is the first time since the 2003 Buenos Aires provincial elections and the second time since the restoration of democracy in 1983 that the provincial elections in Buenos Aires were held on a date other than the national elections.

The Justicialist Party won 47% of the vote, followed by La Libertad Avanza of President Javier Milei at 34%. [2]

The electoral victory of the left sparked widespread panic across financial markets, causing the peso to plunge by nearly 10% in a matter of hours. This sharp decline was fueled by concerns among investors about the potential downfall of President Javier Milei’s pro-market, business-friendly libertarian administration. [3]
