Ken Griffin’s Citadel purchased the majority of Situational Awareness’s public stock portfolio. Former OpenAI researcher Leopold Aschenbrenner manages the AI-focused hedge fund.
The fund suffered a 67% value loss during a sharp July selloff in AI technology stocks. High leverage and concentrated bets on AI infrastructure drove the liquidation.
Prime brokers issued forced margin calls following the reversal of gains seen through June 2026. Situational Awareness retains approximately $10 billion in assets, including a private stake in Anthropic.
