Ken Griffin's Citadel stepped in to purchase the bulk of Situational Awareness's public stock holdings, valued at over $10 billion, following heavy losses incurred by the AI-focused hedge fund. This acquisition, which occurred on Thursday, July 30, effectively offloaded the leveraged portion of Situational's portfolio that was financed by brokers, and reportedly helped stabilize the broader AI market.
Situational Awareness, managed by former OpenAI researcher Leopold Aschenbrenner, was down approximately 67% in July after facing margin calls due to a significant rout in AI stocks. The fund, which had managed around $20 billion in assets, was under pressure to either raise fresh capital or sell its entire portfolio. Citadel's intervention is seen by some as having prevented a further downward spiral in AI stocks, potentially signaling a bottom for the sector. Shares of AI companies like Broadcom, Intel, and CoreWeave, which were among Situational's holdings, saw a subsequent rally.
Citadel, with about $71 billion in assets under management, became one of the largest holders of AI stocks through this deal. Interestingly, this move represents a shift for Griffin, who had previously expressed skepticism about some AI technology. The deal was facilitated by several top Wall Street prime brokers, including Goldman Sachs, JPMorgan Chase, Bank of America, and Citigroup. Situational Awareness will retain a book of roughly $10 billion, including its private investments like a $5 billion stake in Anthropic, which was not sold.
The volatility in the AI sector highlights the influence of short-term traders and sentiment, with price action often becoming disconnected from fundamentals. Despite the recent rally, some analysts note that the iShares Semiconductor ETF (SOXX) is still well below its peak from the end of June. The rapid rise and subsequent distressed sale of Situational Awareness's assets have captivated the industry, underscoring the risks associated with highly leveraged bets in fast-moving sectors like AI, where market downturns can trigger margin calls and accelerate selling pressure. Hedge funds globally faced significant drawdowns, with Asia-focused long-short funds down an average of 18.6% through July 28.
Aschenbrenner’s fund, founded in 2024, had achieved remarkable returns of 439% from the start of 2026 until the end of June, building a cult-like following among investors. However, the AI meltdown in July forced its significant asset reduction. In addition to public tech names, Situational also held private stakes in companies like Anthropic PBC and Nebius Group NV, and was exposed to the AI boom through Asia-based companies such as SK Hynix Inc., whose American depositary receipts have declined since their listing.
