AI Hedge Fund Liquidation and Regulatory Scrutiny

Overview

Leopold Aschenbrenner’s AI-focused hedge fund, Situational Awareness, which had ballooned to approximately $45 billion AUM and delivered a 439% return by June 2026, suffered a 67% plunge in its public-equity portfolio in July 2026. The collapse was triggered by margin calls following sharp declines in semiconductor and AI infrastructure stocks. The fund, which reportedly utilized up to 400% leverage, saw its AUM drop from $45 billion to approximately $10 billion by mid-August. Specific drivers included massive losses in SanDisk (down 47%) and Micron Technology (down 29%), alongside a 31% drop in Bloom Energy. To meet margin calls, the fund sold most of its $16-$20 billion public holdings—including positions in SK Hynix, CoreWeave, and various Bitcoin mining stocks like Core Scientific and Riot Platforms—to Ken Griffin’s Citadel. Following the acquisition, Citadel executed nearly 100 block trades totaling over $4 billion to offload more than 80% of the inherited risk, stating an aim to be “front-footed and proactive during periods of market dislocation.” The volatility had broader institutional impacts; Jane Street reported a $15 billion loss in July, its first monthly slump in a decade, partly due to its investment in Situational Awareness shrinking from nearly $10 billion to between $3 billion and $3.5 billion. In response to the collapse, the SEC has issued subpoenas to major banks, including Bank of America, Citi, Goldman Sachs, and JPMorgan Chase. The investigation seeks information regarding the fund’s trading activity, the timing of trades that triggered margin calls, and communications between the fund and its lenders concerning the extent of its leverage. The agency is examining borrowing practices used to intensify investments in firms like Micron and SanDisk, though it has not accused Situational Awareness or its leadership of any wrongdoing. The fund has stated it intends to cooperate fully with regulators.
