AI hedge fund Situational Awareness may have sold its public portfolio, but it still has its Anthropic shares

Overview

The former OpenAI researcher's fund was forced to unwind public equities after leveraged public bets plummeted. But he still has cards to play. Situational Awareness, a hedge fund formed by former OpenAI researcher Leopold Aschenbrenner, has sold the majority of its public stock portfolio to Ken Griffin's Citadel following steep losses over the past month, The Wall Street Journal reported earlier on Thursday.

    Some of the hardest-hit stocks held by the fund included memory chip producers SK Hynix and Sandisk, clean energy developer Bloom Energy, and neocloud provider Nebius Group, all of which have plummeted by more than 30% over the past month.

  • Early backers of the fund include quant-trading firm Jane Street, Stripe co-founders Patrick and John Collison, and Meta executives Daniel Gross and Nat Friedman.

" German-born Aschenbrenner, who is 25, had no prior trading experience before launching the fund in 2024. He gained prominence for his investment thesis after publishing essays arguing that scaling AI would require a major build-up in semiconductors, compute, memory, and energy infrastructure.

He joined OpenAI's "superalignment" team in 2023, two years after graduating as valedictorian from Columbia at 19 (he enrolled at age 15). But he was dismissed from the company a year later over what it described as an improper disclosure of internal information. At the time, that team was led by OpenAI co-founder Ilya Sutskever and AI researcher Jan Leike.
