Peter Thiel’s hedge fund discloses a stake in Argentina’s Vista Energy, prompting shares and American depositary receipts to rise in early trading. Multiple outlets report that Thiel Macro LLC bought about $76 million worth of Vista, roughly a 1% holding, according to a securities filing.

CNBC and Quartz say Vista’s ADRs rise by more than 5% in premarket activity after the disclosure. The Buenos Aires Herald and Buenos Aires Times report the stake is connected to Vista Energy’s role in Argentina’s Vaca Muerta shale field, which is widely described as the country’s top oil exporter and a major shale-producing region.

Outlets also place the investment in a broader context. Some sources cite Thiel’s growing engagement with Argentina, including purchasing a home in Buenos Aires and meeting President Javier Milei, who is pursuing market-oriented reforms. Several articles link those reforms—such as changes to oil price and export rules and improved access to global markets—to renewed interest and growth in Vaca Muerta operations. One outlet adds operational detail on Vista’s production scale after years of investment.
