AI Hedge Fund Surges to $20 Billion

A former OpenAI researcher's unconventional AI hedge fund has surged to $20 billion, defying traditional investment strategies with a bold bet on the underlying infrastructure of the AI boom. Leopold Aschenbrenner's Situational Awareness fund has gained roughly 270% after fees this year through May, according to figures reported by the Wall Street Journal.

Aschenbrenner's strategy is centered around the idea that the real winners in the AI boom will not be the companies developing the AI technology itself, but rather those providing the necessary infrastructure to support it. He refers to this approach as betting on the 'shovels' rather than the 'gold' in a gold rush analogy.

The fund's largest public holding is Bloom Energy, a company that makes fuel cells to generate power on site. Aschenbrenner also owns CoreWeave, which rents out AI computing power, as well as several former mining data centers now running AI. In a clever twist, while betting on power, he is also betting against the chipmakers everyone loves, including Nvidia, with short bets totaling over $1.5 billion.

Aschenbrenner's single largest position is not a stock at all, but a private slice of Anthropic, the company behind the Claude chatbot. He bought in during February 2025, when Anthropic was worth about $60 billion, and by May 2026, that price tag had jumped to $965 billion after a fresh funding round. This one bet now makes up roughly a fifth of the whole fund.

The fund's success has not gone unnoticed, with secretive trading giant Jane Street also putting money into the fund. However, the strategy is not without risk, and if companies slow their AI spending or the power crunch eases, the fund could fall just as fast as it rose.

The coming months will be crucial in determining whether Aschenbrenner's unconventional approach will continue to pay off. As the AI industry continues to evolve, one thing is clear: the winners will not only be those who develop the most advanced AI technology, but also those who provide the necessary infrastructure to support it.

Market reaction to the fund's strategy has been mixed, with some investors praising Aschenbrenner's bold approach and others expressing concerns about the risks involved. Institutional impact has also been significant, with the fund's success attracting attention from major investors and sparking a wider debate about the role of infrastructure in the AI boom.
