Summary
Leopold Aschenbrenner's Situational Awareness hedge fund has transferred the majority of its publicly traded stock holdings to Ken Griffin's Citadel following substantial losses incurred on artificial intelligence infrastructure investments. The transaction, reported by The Wall Street Journal, culminated efforts by Situational Awareness to identify buyers for these positions and secure fresh capital amid market volatility in the AI sector.
The fund's affected positions included shares in South Korean semiconductor manufacturer SK Hynix and other AI infrastructure companies that experienced sharp declines as broader market skepticism toward AI valuations intensified. Notably, SK Hynix has subsequently recovered, with the stock trading approximately 16% higher at the time of reporting and the company announcing a 557% year-over-year increase in operating profit, highlighting the sector's volatility and Situational Awareness' potential exit timing concerns.
Situational Awareness, launched approximately two years ago by Aschenbrenner—a former OpenAI researcher—had expanded to manage well over $20 billion before the recent downturn. The fund experienced sharp recent drawdowns in long AI infrastructure positions alongside adverse moves in certain short positions, though it maintained significantly positive year-to-date performance through June. The sale attracted multiple bidders, including Millennium Management, which also submitted a proposal for the portfolio during the competitive process.
The fund has retained its private equity investments, which include a meaningful position in Anthropic, a leading AI developer, and continues to engage with investors regarding potential capital commitments beginning in August. Management has highlighted an anticipated Anthropic initial public offering as a significant near-term catalyst, suggesting confidence in the underlying value of retained private holdings despite recent public market setbacks.
