Peter Thiel is scheduled to meet Javier Milei on Thursday at 2:00 p.m. in Buenos Aires, one of the Argentine president’s first activities after returning from his official trip to Israel. It will be the fourth time the two have met in two years.
Thiel and Milei first met in January 2024 at the Casa Rosada, then again in May 2024 in Los Angeles during the Milken Institute forum. They met once more in Buenos Aires before Thursday’s sit-down, underscoring a relationship that has moved from one-off contact to repeated in-person exchanges.
The timing matters because Thiel has already spent at least a week in Buenos Aires with his family, according to local media, staying in a luxurious home in Barrio Parque. During the visit, he also had lunch with Santiago Caputo and dined at the home of Federico Sturzenegger, while on Sunday he watched River Plate beat Boca Juniors by a single goal at the Monumental Stadium.
That visit has drawn attention well beyond the social calendar. Thiel is closely linked to Palantir, the data-processing company whose work has been central to tracking and monitoring people suspected of being undocumented immigrants in the United States, and the company has faced criticism for its support of artificial-intelligence weapons and military uses. Palantir has defended that stance by saying it will not indulge in theatrical debates about technologies with critical military and national security applications, arguing instead that the atomic age is ending and a new era of deterrence built on A.I. is set to begin.
Milei has spoken in sweeping terms about Argentina’s future, saying the country has all the conditions to be the new mecca of the West. But the meeting comes as he faces his lowest approval ratings since taking office in December 2023, which is why Thiel’s return is being watched so closely. With more than 440,000 people deported in 2025, the mix of immigration enforcement, artificial intelligence and political alignment gives the meeting a sharper edge than a private visit would usually have.
The broader question is not whether Thiel is passing through Buenos Aires. It is how much of this relationship is becoming part of Milei’s political message, and whether Thursday’s meeting signals a deeper alignment between Argentina’s president and one of Silicon Valley’s most influential and controversial figures.
