Peter Thiel’s hedge fund just made a splashy new bet on South American energy. A fresh SEC filing published Friday shows Thiel Macro LLC built a stake worth about $76 million in Vista Energy, Argentina’s largest independent oil producer, sending the stock up nearly 4.3% in Monday’s premarket trading. The position, made up of almost 1.2 million American Depositary Shares as of the second quarter, is now Thiel’s second-largest disclosed holding behind Amazon.
The filing reveals more than just one trade — it shows a broader energy and power thesis. Six of Thiel Macro’s seven new positions disclosed this quarter were in energy or utility names, including American Electric Power, DTE Energy, FirstEnergy, CMS Energy, Vistra, and X-Energy. Vista Energy itself operates out of the Vaca Muerta shale formation and has poured more than $6.5 billion into Argentine operations. The timing isn’t random: Thiel relocated to Buenos Aires earlier this year and has met repeatedly with officials in President Javier Milei’s government, including Economy Minister Luis Caputo, as Argentina pushes aggressive reforms to attract foreign capital into oil, lithium, and rare earth minerals.
For retail investors who track billionaire 13F filings for ideas, the read-through is bigger than one stock. Thiel’s cluster of new positions signals conviction that power and energy infrastructure — supercharged by AI-driven electricity demand and reform-friendly emerging markets — is where smart money is rotating next. Vista Energy (NYSE: VIST) could be worth researching for investors seeking commodity exposure paired with policy tailwinds, but remember this is a single-stock, emerging-market energy bet — currency swings and political risk in Argentina mean position sizing matters more than usual here. Investors who want the theme without single-country risk could also look at the broader utility and power names Thiel added this quarter, which trade with far less volatility than a single emerging-market energy name.
