Peter Thiel’s Second-Biggest Bet is Not a Tech Stock Anymore

Peter Thiel has made his second-largest investment not in a technology stock, but in an Argentine oil producer. His investment firm, Thiel Macro, purchased nearly 1% of Vista Energy, paying around $76 million for approximately 1.2 million shares. This information was disclosed in a filing with the U.S. Securities and Exchange Commission (SEC). Now, Vista ranks as Thiel's second biggest holding, accounting for $75.9 million, or 18.1%, of the fund's disclosed positions worth $418.7 million for the second quarter of 2026.

Vista Energy is primarily involved in drilling in Vaca Muerta, a significant shale formation in Argentina. This field holds the second-largest shale gas reserves and the fourth-largest shale oil reserves in the world. In Q2 2026, output reached 156,061 barrels of oil equivalent per day, marking a 16% increase from the previous quarter. Vista has committed over $6.5 billion to Argentina, and it raised its production outlook in May.

The timing of this investment is influenced by Thiel's meeting with President Javier Milei, who later mentioned discussing economic policy and a shared dislike for wealth taxes. Since then, Argentina's inflation has been on a downward trend under Milei's presidency. Additionally, Thiel expanded his portfolio by buying a mansion in a prestigious Buenos Aires neighborhood.

Tax policy plays a significant role in this story as well, as wealthy investors have been seeking lower-tax jurisdictions, and Milei openly courts such investments.

For crypto enthusiasts, this shift in Thiel's investment strategy from digital assets to commodities and equities is more noteworthy than the specific ticker symbol. The success of this wager depends on two factors: Vaca Muerta's output and Milei's ability to maintain his reform program.
