Peter Thiel Builds $419M Portfolio Around Amazon, Energy and AI Power Demand

Peter Thiel’s hedge fund has rebuilt its public-equity portfolio around one of the biggest constraints facing artificial intelligence: electricity.

Thiel Macro disclosed eight U.S.-listed holdings worth $418.7 million at the end of the second quarter, according to its 13F filing. Amazon was the only technology company in the portfolio, while the remaining positions were concentrated in oil, electricity generation and regulated utilities.

The filing marks a sharp change after the fund reported no meaningful long U.S. equity positions in the previous two quarters.

Amazon Leads a Portfolio Dominated by Energy

Amazon was Thiel Macro’s largest position at about $118 million, representing roughly 28% of the disclosed portfolio. The investment gives the fund direct exposure to the AI infrastructure boom through Amazon Web Services.

The timing is notable. Amazon has raised its 2026 capital-spending plan to $220 billion, with much of that spending directed toward cloud infrastructure, AI computing and data centers.

That level of spending also reinforces the investment case for companies supplying electricity to data centers. Coinpaper’s overview of leading data centers highlights the growing importance of power, cooling and physical infrastructure as AI workloads expand.

Vista Energy was Thiel Macro’s second-largest holding at $75.9 million, followed by power generator Vistra at $59.1 million. Thiel’s Vista position represents roughly 1% of the company, which is a major producer in Argentina’s Vaca Muerta shale region.

Utilities Become an AI Infrastructure Trade

The remainder of the portfolio included American Electric Power, DTE Energy, FirstEnergy and CMS Energy, with each position worth roughly $40 million to $42 million. Nuclear developer X-Energy was the smallest holding at about $3.7 million.

The allocation suggests that Thiel Macro is looking beyond the semiconductor layer of the AI boom. Coinpaper’s guide to AI chips shows how Nvidia, AMD and Broadcom remain central to AI spending, but electricity availability is increasingly becoming a separate investment theme.

That trend is already reshaping other industries. Bitcoin miners with large power connections are increasingly being valued as potential AI infrastructure providers rather than simply crypto producers, a shift visible in recent mining stocks.

AI’s Power Bottleneck Moves Into Focus

Electricity constraints are becoming harder for investors to ignore. Grid connection delays are already pushing some businesses toward larger on-site generation systems, while AI developers continue searching for locations with sufficient power capacity.

Thiel Macro’s filing does not prove that every position was purchased specifically because of AI. A 13F also shows only certain long U.S.-listed holdings and represents a snapshot from June 30, meaning the portfolio may have changed since then.

Still, the concentration is striking. Rather than assembling another portfolio dominated by semiconductor stocks, Thiel Macro has placed most of its disclosed capital in companies tied to the energy system supporting the AI buildout.
