Leopold Aschenbrenner, a 24-year-old former OpenAI researcher, has built his AI fund, Situational Awareness, into a behemoth with over $200 billion in assets. Now, quantitative trading giant Jane Street has made a rare investment in the fund. After fees, Situational Awareness is up 270% this year and has delivered cumulative returns exceeding 1,000% since inception. The fund's most successful bet has been an equity stake in Anthropic, which alone accounts for one-fifth of its assets. The news comes as Aschenbrenner's fund continues to attract major institutional attention.
