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

Peter Thiel has bought close to 1% of Vista Energy, an Argentine oil producer. His fund paid roughly $76 million for about 1.2 million American depositary shares.

The purchase was disclosed in a quarterly filing with the U.S. Securities and Exchange Commission (SEC). Vista now ranks second among Thiel’s disclosed holdings.

Inside Thiel’s $76 Million Vista Energy Stake

Thiel Macro reported eight positions worth $418.7 million for the second quarter of 2026. Vista accounts for $75.9 million of that total, or 18.1%.

Thiel Macro also expanded fast. It listed a single holding a quarter earlier, then disclosed eight.

Only Amazon (AMZN) ranks higher at 28.2%. Meanwhile, three power companies absorb much of the rest. Vistra, American Electric Power, and DTE Energy together make up roughly 34% of the book.

The shape of that portfolio reads as an energy bet, not a technology one. Thiel has pulled back elsewhere this year. In February, his Founders Fund exited an Ethereum treasury firm as digital asset treasury companies came under pressure.

His stock picks have also stumbled. In May, another Thiel-backed stock lost half its value after a Las Vegas debut fell flat.

The filing is dated Aug. 14 and covers positions held through June 30. Quarterly disclosures lag the market, so the fund may have changed its position since then.

Vista therefore stands out in Thiel’s book. It is the largest single wager outside Big Tech.

Why The Billionaire Is Betting on Vaca Muerta Oil

Vista drills in Vaca Muerta, a shale formation roughly the size of Belgium. The field holds the world’s second-largest shale gas reserves and its fourth-largest shale oil reserves.

Output reached 156,061 barrels of oil equivalent per day in the second quarter, a 16% rise from the first. Vista has committed more than $6.5 billion to Argentina, and it raised its production outlook in May.

Politics helps explain the timing. Thiel met President Javier Milei at the presidential palace in Buenos Aires four months ago. Milei later told local media that they discussed economic policy and a shared dislike of wealth taxes.

Since then, Argentina’s inflation under Milei has kept falling, though economists still doubt how durable the peso fix will prove. Thiel also bought a mansion in an upscale Buenos Aires neighborhood.

Tax policy runs through the story as well. Wealthy investors spent 2026 hunting lower-tax jurisdictions, and Milei courts that money openly.

For crypto readers, the rotation matters more than the ticker. Capital that once chased digital assets has drifted toward commodities and equities through this downturn. Thiel’s filing lands squarely in that trend.

Whether Thiel’s wager pays now depends on two things: Vaca Muerta output and Milei’s ability to keep his reform program intact.
