Leopold Aschenbrenner's Situational Awareness hedge fund rebounds after 67% loss, secures new investor interest

Aug 6, 2026

Leopold Aschenbrenner's AI-focused hedge fund, Situational Awareness, secures fresh interest from Silicon Valley investors despite suffering a devastating 67% loss in July 2026. The fund was forced to sell its $45 billion public book to Citadel for $10 billion after leveraged bets on companies like SK Hynix triggered margin calls. Undeterred, Aschenbrenner is pivoting to physical infrastructure, investing $400 million in lithography startup Source Foundry to challenge ASML's chip-making dominance.
