AI-Focused Hedge Fund Loses 67 Percent in July; Citadel Steps In
Leopold Aschenbrenner, a 24-year-old German investor, launched the AI-focused hedge fund Situational Awareness just two years ago. The fund’s rapid rise was fueled by a bold strategy targeting artificial intelligence, with its portfolio ballooning to 45 billion dollars in just over two years. By May, the fund had already achieved a staggering 1000 percent profit from its inception, and 270 percent profit after fees.
High-profile supporters of the fund included Wall Street giant Jane Street, a major player in algorithmic trading, and the twin founders of the financial services firm Stripe. Situational Awareness built its business around the argument that AI’s explosive growth would require massive infrastructure investments, including powerful semiconductors, expanded computing power, and new energy systems. This vision helped the fund quickly capture attention and capital.
Portfolio Collapse Begins
The fund’s fortunes took a sharp downturn when a key part of its portfolio—semiconductor stocks—began to collapse. SK Hynix, a major holding, saw its stock value multiply more than threefold between March and mid-June. However, within weeks of hitting that peak, the stock lost nearly half its value. This dramatic shift signaled the start of the fund’s unraveling.
Other significant holdings, such as shares of the Nebius Group, also saw their value drop sharply in the market. The losses were made worse by Situational Awareness’s heavy use of leverage. For every dollar of equity the fund held, it borrowed up to four dollars from banks, which amplified both gains and losses. When these positions began to falter, the impact was severe.
As news of Situational Awareness’s struggles spread in the financial industry, some competitors began short-selling the fund’s top holdings. By dumping large amounts of stock, they aimed to drive prices down further and force Aschenbrenner to sell assets at a steep discount. This created additional pressure on the fund’s already weakened balance sheet.
Liquidity Crisis Erupts
Banks, which had initially extended large sums to the fund, now demanded more collateral. This created an immediate liquidity crisis and forced Situational Awareness into urgent negotiations with other Wall Street players. Citadel, a major hedge fund managed by Ken Griffin, and Millennium were among the companies involved, but in the end, Citadel came out as the winner.
Citadel acquired the listed portion of Situational Awareness’s portfolio at a 10 percent discount. This move fits a pattern Citadel has used in the past, such as when it bought parts of the bankrupt energy giant Enron in the early 2000s. By capitalizing on the financial distress of others, Citadel has historically been able to secure assets at a significant discount.
Strategic Shift and Recovery
Following the sale, Situational Awareness’s portfolio dropped to around ten billion dollars, and the fund shifted its focus to private investments. Among the non-listed assets it now holds is a 3.5 billion dollar stake in Anthropic, an influential player in the AI space. This change reflects a strategic shift toward more stable and less volatile assets.
Aschenbrenner had built a reputation in financial circles through a series of essays titled 'Situational Awareness - the coming decade,' published in 2024. In these pieces, he outlined his belief that AI would drive massive demand for computing power, better semiconductors, and expanded energy systems. His insights helped him attract big names in the industry and launch a fund that, at its peak, was one of the fastest-growing in history.
