Dozens of protesters gathered this week at the mansion of billionaire Peter Thiel in Buenos Aires, raising concerns about his growing influence in Argentina. The demonstrators, wearing white masks, carried signs reading "Peter Thief" and "No to the Peter Thiel law" outside the $12 million home Thiel purchased in April as he moved his family to the country. Their presence reflects broader public unease over Thiel’s role in Argentina, where his relocation has sparked speculation about both personal and political motivations. Thiel, a prominent tech investor and co-founder of Palantir, a data analytics company, has been linked to a series of proposed regulatory changes introduced by Argentina’s far-right president, Javier Milei. Last week, Argentina’s chamber of deputies held a six-hour session to discuss these reforms, which include measures aimed at attracting foreign investment and reducing restrictions on land ownership. However, neither Thiel nor Milei attended the session, and officials from the government’s intelligence services also failed to appear, despite being invited. Juan Marino, a deputy and leader of the Piquetero party, criticized the proposed laws as a "technofascist legislative package" that could empower U.S. tech billionaires in Argentina. Among the most controversial proposals is the "super RIGI," a law that would offer foreign companies a low tax rate and a 30-year guarantee against regulatory changes, specifically targeting investments like AI data centers. Another proposed law, which did not pass, aimed to remove restrictions on foreigners buying land in Argentina. A third measure would require government agencies to share large amounts of personal data on citizens with the country’s intelligence services. While Thiel has not publicly endorsed these laws, he has met privately with Milei and his advisers, raising questions about his influence on the reforms. Critics argue that the proposed reforms align with Thiel’s broader techno-libertarian vision, which includes creating autonomous zones free from traditional state control. These ideas are reminiscent of projects like Próspera, a controversial "startup city" in Honduras that Thiel has supported. Cecilia Nicolini, an Argentine representative in the Mercosur regional parliament, said that U.S. tech billionaires are using Argentina as a testing ground for their policies, with Milei’s government serving as a political ally. She noted that Milei has even advocated for "non-human corporations" — AI-run entities — a concept that raises complex questions about legal accountability and governance. While Thiel has not publicly commented on these concerns, the growing scrutiny highlights the intersection of tech innovation, political reform, and national sovereignty in Argentina.
