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

Situational Awareness, a hedge fund led by former OpenAI researcher Leopold Aschenbrenner, has sold most of its public portfolio following significant losses. Despite the fund's recent decline, Aschenbrenner maintains his bullish thesis on AI infrastructure and retains his stake in Anthropic.

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.

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.
