Key Points
—Argentine President Javier Milei will host Palantir co-founder Peter Thiel at Casa Rosada at 14:00 on Thursday, April 23 — the first formal activity after the president’s return from his third state visit to Israel, and Thiel’s third known encounter with Milei since February 2024.
—Thiel — whose estimated fortune ranges from US$23 billion to US$27 billion — has been in Buenos Aires for more than a week on a private agenda: lunch with presidential advisor Santiago Caputo, dinner at the home of Deregulation Minister Federico Sturzenegger, and attendance at Sunday’s Superclásico at the Monumental.
—Thiel has reportedly acquired or rented a property in the Barrio Parque neighbourhood and plans an extended two-month stay, arriving as Milei navigates a tight currency situation, a $20 billion IMF program, and active US-Argentina strategic materials talks.
The Thiel Milei Argentina meeting at Casa Rosada caps a week of private encounters between one of Silicon Valley’s most politically-connected billionaires and the inner circle of Latin America’s most Washington-aligned president.
The Rio Times, the Latin American financial news outlet, reports that Argentine President Javier Milei will receive Palantir co-founder Peter Thiel at Casa Rosada at 14:00 local time on Thursday, April 23, according to Casa Rosada sources cited by EL PAÍS and confirmed by Bloomberg Línea. The meeting is Milei’s first major activity after returning from his third state visit to Israel and the third formal Thiel Milei Argentina encounter on record, following bilateral exchanges in February and May 2024. Thiel co-founded PayPal with Elon Musk in 1998 and Palantir Technologies in 2003 with CIA venture capital, building a data-analytics company that supplies surveillance and targeting software to Western intelligence, defence, and law-enforcement agencies.
The billionaire’s agenda in Buenos Aires has been deliberately private: a Monday lunch with Santiago Caputo, Milei’s strategic advisor and the administration’s principal link to Washington; a dinner at the residence of Deregulation and State Transformation Minister Federico Sturzenegger; and attendance at Sunday’s River Plate–Boca Juniors Superclásico at the Monumental. According to Bloomberg Línea, Thiel has either acquired or rented a property in Barrio Parque, the diplomatic-quarter of Buenos Aires, with local reporting suggesting a two-month planned stay. His fortune is estimated at US$23 billion by Forbes and US$27 billion by Statista.
Why Thiel is in Argentina now
Thiel has publicly framed Milei’s libertarian program as globally significant. At the Milken Institute conference in Los Angeles in May 2024, he said Milei had “decent chances of being successful” given the decadence of alternative models, and Argentina ambassador Alec Oxenford described Thiel as considering Milei’s ideas “as globally relevant as they are for Argentina.” The framing positions Buenos Aires as a test case — a “warning for developed economies” in Thiel’s words — and explains the concentrated personal engagement since the Milei inauguration.
Local analysts have linked Thiel’s timing to Argentina‘s present difficulties: a complex currency position, scandals inside the president’s inner circle, and the fact that Milei’s approval has slid to 36% — the lowest of his term. Valeria Di Croce, author of El Arca de Milei, told EL PAÍS that Palantir’s offer to Argentina is “a tool of surveillance and control,” while the broader US interest is in “cheap energy, raw materials, water and large land extensions.” Foreign Minister Pablo Quirno’s recent signing in Washington was described by Di Croce as making Argentina a “national-security supplier” rather than a participant in technology development.
The Palantir surveillance franchise context
Palantir’s commercial profile is built on contracts with the US Department of Defense, the FBI, ICE, and the intelligence community, alongside similar deployments in the United Kingdom, Israel, and NATO-aligned governments. The company’s systems were instrumental in the tracking and targeting architecture that supported the 440,000-plus deportations executed by US Immigration and Customs Enforcement during 2025. Thiel himself remains the chairman of Palantir’s board, and his partner Matt Danzeisen is the company’s principal shareholder.
A manifesto published on Palantir’s corporate account this week — a 22-point text summarizing Thiel’s forthcoming book La República Tecnológica — argues for restoring compulsory military service and developing AI-enabled weapons systems, on the premise that adversaries will not pause for “theatrical debates.” The text frames the post-atomic era as one built on AI-based deterrence. Reporting from Izquierda Diario notes that possible integrations between Argentina’s SIDE intelligence service and Palantir are among the topics believed to be under discussion.
The Thiel Milei Argentina meeting in broader strategic context
The encounter lands inside an already dense US-Argentina timeline. Washington has backed Milei’s economic program with a US$20 billion IMF program and currency-stabilization signals, and the US-Argentina framework agreement signed in November has moved the relationship closer to formal alignment. The same month, Argentina designated Iran’s IRGC as a terrorist organization, consolidating what The Rio Times has described as Buenos Aires’s alignment with Washington and Jerusalem.
For international investors, the Thiel visit is a signal rather than a transaction. Argentina’s economy grew 4.4% in 2025 after the -1.7% contraction of 2024, with annual inflation closing at 31.5% after peaking at 211% in 2023. A US private-capital push into Argentine strategic materials, AI infrastructure, and security contracting would be a logical next step in a relationship that already runs through the IMF, the Treasury, and the White House — and that now appears to extend through Silicon Valley’s most politically-aligned billionaire.
What to watch after Thursday’s meeting: any public Palantir announcement on Argentine intelligence, defence, or customs contracting; any changes to Argentina’s strategic-materials export framework under the existing RIGI investment regime; and whether Thiel’s planned two-month stay converts into capital commitments, co-investment signals, or open advocacy for the Milei program ahead of Argentina’s return to international debt markets. The commercial and political stakes are captured in The Rio Times’s analysis of the Trump-Milei trade pact.
