Leopold Aschenbrenner, in his mid‑20s, runs a hedge fund called Situational Awareness that he launched in 2024 after publishing a 165‑page essay arguing that artificial superintelligence would transform society. Investors responded quickly and within months he was managing hundreds of millions of dollars; by July he was said to be overseeing as much as $45bn. The fund reported a 67% loss in July and on 30 July offloaded most of its listed shares to Citadel at speed.
Regulatory filings show the fund was heavily exposed to firms providing electricity and hardware used by AI, including Bloom Energy, CoreWeave and Sandisk, each of which lost more than half their value from recent peaks before Citadel’s intervention. Aschenbrenner had reported 439% returns for the first half of 2026, a performance that suggests either extraordinary luck or substantial borrowing. A Bank of America survey found “long global semiconductors” to be the most crowded trade, raising concern that the reversal could affect other managers.
The reporting sets out the sequence of rapid growth, concentrated bets and a swift sale to a larger firm, but some surrounding language and comparisons verge on sensationalism. Framing investors as simply reckless risks oversimplifying a situation that also involved massive flows into crowded trades and limited public detail about the fund’s actual leverage. Parallels with past collapses such as LTCM underline the dangers of borrowing, but LTCM differed in experience, scale and strategy, so direct comparisons should be cautious. Public filings do not yet show systemic contagion, so uncertainty remains about how far the fallout will spread.
