Thiel fund went dark for two quarters – came back with 72% in energy

From silence to a blockbuster in one quarter

Peter Thiel's hedge fund Thiel Macro was effectively invisible in the U.S. equity market throughout the second half of 2025 and into 2026. According to public SEC filings (13F filings), the fund reported no long equity positions in the United States for either the quarter ending December 2025 or the quarter ending March 2026.

Then, in the second quarter of 2026, something dramatic happened: Thiel Macro reappeared with declared holdings of nearly $419 million – and almost three-quarters of that capital is parked in a single sector.

Energy and power dominate the portfolio

According to the quarter's 13F filing, the portfolio's center of gravity is heavily tilted toward energy infrastructure and power generation. The largest positions include:

Amazon is also part of the portfolio – a company that, according to research sources, has estimated capital expenditures of $220 billion in 2026, largely tied to cloud and AI infrastructure.

The thesis: AI is creating a new energy crisis

Underpinning Thiel Macro's bet is a clear investment logic: the explosive growth of artificial intelligence will make access to electricity the decisive bottleneck – not access to chips or software. According to research based on SEC filings, this is a thesis shared by several prominent investors globally.

The energy sector did in fact deliver its best quarterly return in four years in Q1 2026, with a combined gain of nearly 38 percent, according to sector data. Pure-play oil and gas producers rose an average of 45 percent over the same period, driven by geopolitical tensions and elevated commodity prices. It remains unclear to what extent Thiel Macro was already positioned to capture part of that rally.

The crypto dimension: energy as shared infrastructure

Thiel's energy investments also touch the cryptocurrency sector indirectly. Analysts note that Bitcoin miners with large power contracts are increasingly being evaluated as potential AI infrastructure providers, rather than purely as crypto producers. The energy investments are viewed as "a bullish infrastructure play for cloud, power, and crypto-related investors," according to research available to 24markets.

Meanwhile, Founders Fund, Thiel's primary venture capital vehicle, has been active in the crypto sector: in July 2025 the fund disclosed a 9.1 percent stake in crypto mining company BitMine Immersion Technologies. In February 2026, however, Founders Fund's 7.5 percent stake in Ethereum treasury company ETHZilla was fully unwound – illustrating the risks of debt-driven crypto strategies combined with high volatility.

A familiar pattern: Thiel has done this before

This is not the first time Thiel's fund has executed an abrupt, concentrated re-entry. Founders Fund became an early institutional investor in Bitcoin in 2014, exited crypto positions in 2022 with estimated gains of $1.8 billion, and then re-entered with $200 million in Bitcoin and Ethereum in 2023.

The pattern is recognizable: periods of no reported positions, followed by large, high-conviction reallocations into whatever the Thiel orbit identifies as the next structural shift.

Whether the energy-AI thesis will deliver returns comparable to those crypto entries remains to be seen. But with $419 million on the table and three-quarters of it in power and energy, there is little doubt about what Thiel Macro believes is the defining infrastructure of the next decade.
