Thiel's Argentine Gambit: Tech Magnate Builds South American Base Amid Geopolitical Realignment

Peter Thiel showed up at a chess tournament in Abasto, a middle-class neighborhood of Buenos Aires, on a Saturday afternoon in late spring. He paid 3,000 pesos—less than two euros—to enter the Torre Blanca Chess Club's competition, played several rounds, finished third, and left with a medal worth perhaps a dollar. He was so relaxed, so absorbed in the game, that he stayed an hour longer than he'd planned. For a man whose fortune sits at roughly 30 billion dollars, the moment was oddly ordinary. It was also, in its way, a signal.

Thiel arrived in Argentina in April, having purchased a twelve-million-dollar mansion in Barrio Parque, the neighborhood where Buenos Aires keeps its wealth. His children now attend school locally. He has met with President Javier Milei, with the economy minister Luis Caputo, and with Federico Sturzenegger, the minister of deregulation, who hosted him for dinner alongside the foreign minister. The libertarian circle around Milei has already begun floating the idea of offering him Argentine citizenship—a gesture that would mean little to a man who was born in Germany, raised in the United States, acquired New Zealand nationality in 2011, and received a Maltese passport in 2022.

Thiel is not in Argentina by accident. He is following a thread that the Argentine-Spanish entrepreneur Martín Varsavsky laid out in these pages in March 2025, when Varsavsky described Argentina as a potential sanctuary in the event of nuclear war. The Pampas, Varsavsky argued, would be among the last places on Earth to experience the temperature collapse that would follow atomic exchange—the "nuclear winter" that would devastate grain-producing regions like the American Midwest and Ukraine. Argentina, with 47 million people capable of producing food for 500 million, could survive what much of the world could not. Varsavsky proposed a "tranquility visa" to the Milei government, modeled loosely on Trump's recent gold visa program, priced at half a million dollars. Milei listened. Thiel is precisely the sort of person such a visa was designed to attract.

The magnate has local leverage beyond his wealth. Alex Oxenford, now Argentina's ambassador to the United States, was a friend of Varsavsky's and, fifteen years ago, received investment from Thiel in OLX, a venture that eventually reached unicorn status—a valuation exceeding one billion dollars. In 2024, Oxenford brought Thiel to the Casa Rosada to meet Milei. The timing was delicate: Milei had recently apologized to Pope Francis for calling him "the representative of evil." Weeks later, at a private dinner with Thiel in Buenos Aires, the magnate began discussing the dangers of the Antichrist to a room of economists and businessmen. He connected this theological concern to what he saw as a global order of moral superiority and state overreach—an order he associated with figures like Greta Thunberg and the left more broadly.

Pola Oloixarac, a sharp columnist for La Nación, sees in Thiel and Milei a shared preoccupation with ordering the human world according to particular principles. Where Elon Musk aims for Mars, Thiel concerns himself with the rules of the game on Earth. He arrives in Argentina as part of what Oloixarac calls "ideological tourism with a planetary perspective," treating every corner of the globe as a potential future amid unknown chaos. "Buying property in Buenos Aires," she writes, "could be the latest word in theological investment, a style for diversifying across the globe, a conscious strategy in the face of possible future Armageddon."

Not everyone welcomes him. Elisa Carrió, a veteran center-left political leader and longtime scourge of corruption, has called Thiel's presence in Argentina "terrible." She warns that Palantir Technologies, the data-analysis firm Thiel co-founded in 2003 with CIA backing, operates against the republic, democracy, and freedom. Palantir develops platforms used by defense agencies, intelligence services, and governments worldwide. Thiel's closeness to Donald Trump—whom he supported in the last two presidential campaigns—and his early investment in Facebook (half a million dollars in 2004) have made him a central figure in the architecture of American power.

Argentina is now Thiel's base for deepening influence across South America. He has visited Brazil, Chile, Uruguay (where he purchased land near the coast), and Paraguay, where he met with President Santiago Peña, who dreams of making his country "the Qatar of South America" and an artificial-intelligence paradise. Milei himself announced in 2025 a major investment in AI data centers in Patagonia, where cold climate could theoretically cool server farms. Santiago Caputo, Milei's principal adviser, has become one of the government's chief advocates for Thiel's involvement. In a recent post on social media, Caputo outlined Argentina's strategic position: its alignment with the United States and Israel, its natural resources, its geography in the South Atlantic, its proximity to Antarctica. "Argentina will have international relevance in a few years that is not yet fully understood," he wrote. "Fortunately, everything is proceeding according to plan." Peter Lamelas, the U.S. ambassador to Argentina, echoes this view, framing American companies—and by extension, Palantir—as essential to Argentina's energy security and its containment of Chinese influence. What began with a chess medal in a Buenos Aires neighborhood has become something far larger: a geopolitical repositioning, a bet on catastrophe, and a deepening experiment in how power might be organized when the old world breaks down.
