Situational Awareness LP, an AI-focused hedge fund founded by 24-year-old Leopold Aschenbrenner, has surpassed $20 billion in assets under management after delivering roughly 270% in gains after fees in 2026 through May, according to multiple financial sources.
The milestone marks an extraordinary trajectory for a fund launched less than two years ago. Aschenbrenner, a former OpenAI researcher with no professional investing background, seeded the hedge fund in September 2024 with approximately $225 million from prominent Silicon Valley investors including Patrick Collison and John Collison of Stripe, as well as Nat Friedman, former CEO of GitHub.
The fund’s rapid growth reflects investor appetite for AI infrastructure bets. Situational Awareness focuses on companies powering the physical layer of artificial intelligence development—energy providers, semiconductor manufacturing, and computing infrastructure—rather than AI application companies. This thesis distinguishes it from many technology-focused hedge funds that concentrate on software and chip designers.
The fund’s largest position has been Bloom Energy, a distributed power generation company, which Aschenbrenner identified as critical to solving AI’s growing energy demands. By May 2026, the fund had disclosed $13.7 billion in assets, up from $5.5 billion at the end of 2025, representing a 148% quarterly increase in Q1 2026 alone.
Aschenbrenner’s background shaped his investment philosophy. Before launching the fund, he worked on OpenAI’s Superalignment team and published a widely circulated essay titled “Situational Awareness: The Decade Ahead,” which argued that artificial general intelligence development would require massive infrastructure buildout. He graduated from Columbia University as valedictorian at age 19.
The hedge fund industry has seen record growth in 2026, with global hedge fund assets reaching $5.6 trillion by Q2, according to Financial Times reporting. However, Situational Awareness LP’s performance stands apart—the fund has delivered cumulative returns exceeding 1,000% since its September 2024 launch, vastly outpacing typical hedge fund benchmarks and the broader market.
The fund’s investors include venture capital leaders and technology entrepreneurs who recognized Aschenbrenner’s thesis early. Beyond the Collison brothers and Friedman, anchor investors have included Daniel Gross and other prominent figures in the AI community.
