Thiel Macro LLC acquired a 1% stake in Vista Energy. The firm purchased approximately 1.2 million American depositary shares. This transaction is valued at $76 million according to a Securities and Exchange Commission filing.

Vista Energy operates as a major shale oil producer in Argentina's Vaca Muerta region. The investment supports President Javier Milei's strategy to expand national energy production. This acquisition follows a meeting between Peter Thiel and Milei in Buenos Aires four months ago.

Thiel's broader portfolio targets companies positioned to benefit from rising electricity demand. Growth in artificial intelligence and data centers increasingly drives this global power demand.
