NEW YORK, July 30 — Situational Awareness, an AI-focused hedge fund led by former OpenAI researcher Leopold Aschenbrenner, has sold the bulk of its stock portfolio to Ken Griffin’s Citadel following heavy losses in its tech holdings, according to sources familiar with the matter. The fund was forced to unwind most of its public equities portfolio, which included significant positions in Broadcom, Intel, and CoreWeave, after a market selloff battered AI-related stocks. Citadel, one of the world’s largest hedge funds with $71 billion in assets under management, acquired the portion of Situational’s portfolio financed by leverage from brokers, including Goldman Sachs, JPMorgan Chase, Bank of America, and Citigroup. The deal leaves Situational with a remaining book of roughly $10 billion, comprising stocks and private investments, such as its stake in Anthropic, which was not sold.
The fund’s collapse comes amid a broader AI sector meltdown, with global hedge funds experiencing record monthly drawdowns. Jim Cramer, host of CNBC’s Mad Money, described the situation as a cautionary tale about the risks of leveraged investing, noting that Situational’s strategy of long hardware, short software backfired when the trade reversed. The forced liquidation of leveraged positions contributed to recent volatility in AI-related stocks, though some analysts believe the unwinding could mark a turning point by removing selling pressure.
Background: Aschenbrenner’s Rise and Fall
Leopold Aschenbrenner, a Gen Z investor who co-founded Situational Awareness in 2024, gained prominence for his prescient bets on AI, delivering a 439% return from January to June. A German native and Columbia University valedictorian, Aschenbrenner previously worked at OpenAI before being fired in 2024 over allegations of improperly sharing internal information. He denied the claims, stating his dismissal was related to an internal memo about security measures.
Aschenbrenner’s 165-page essay, Situational Awareness, published in June 2024, warned of economic disruptions from AI advancements and potential geopolitical risks. Despite his early success, the fund’s leveraged bets on AI infrastructure—such as Micron and SK Hynix—sourced as software stocks like Adobe and Salesforce rebounded, forcing margin calls.
Market Reactions and Broader Implications
The selloff in AI stocks has been severe, with Micron dropping 39% from its June high before partially rebounding. However, the unwinding of Situational’s positions may have eased selling pressure, as evidenced by a 2.5% surge in the Nasdaq Composite on July 30. Analysts like Cramer argue that forced liquidations often signal a market bottom, though the long-term impact remains uncertain.
The incident has reignited debates over leverage in hedge funds, with critics warning of systemic risks when highly leveraged bets unravel. Meanwhile, some investors see the selloff as an opportunity, with Nvidia, Broadcom, and other AI-related stocks showing signs of recovery.
Key Takeaways
- Citadel acquired Situational’s leveraged stock portfolio after heavy losses in AI holdings.
- Leveraged bets on AI infrastructure backfired, leading to forced liquidations.
- Market volatility may ease as forced selling subsides, but risks remain.
- Aschenbrenner’s rise and fall highlights the risks of high-leverage strategies in volatile sectors.
The situation underscores the fragility of leveraged bets in rapidly evolving markets, particularly in high-growth sectors like AI.
