Leopold Aschenbrenner's AI hedge fund, Situational Awareness, lost roughly $35 billion of investor money in days after leveraged bets on AI infrastructure stocks unwound in margin calls. The fund, which peaked at $45 billion in early July, fell to about $10 billion by late July after running up to 400% leverage on concentrated positions including Nebius Group, SanDisk, CoreWeave, and SK Hynix, while shorts in Adobe moved against it. Within two weeks, Silicon Valley insiders rallied to offer Aschenbrenner fresh capital, though the fund is not accepting new money for now. Aschenbrenner deployed $500 million into private companies post-collapse and retains stakes in Anthropic, signaling conviction from the remaining $10 billion base.
