Citadel Rescues AI Hedge Fund Amid Market Meltdown

In early July 2024, rival hedge fund Citadel stepped in to buy a large portion of the portfolio of Situational Awareness, the hedge fund founded by 24-year-old former OpenAI researcher Leopold Aschenbrenner. After AI-related stocks plunged, Aschenbrenner’s fund scrambled to sell roughly $20 billion of equity within 30 hours. Citadel agreed to purchase much of that stock at a discount, stabilizing the fund and leaving it with about $8 billion of assets—down more than 70 percent from the roughly $30 billion it held at the start of July.

Aschenbrenner launched Situational Awareness in 2024 with $100 million from prominent tech investors, according to the *New York Times*. The fund aggressively invested in AI-adjacent startups and data-center companies, at one point quadrupling investor capital to roughly $30 billion. When AI stocks fell sharply, the fund’s leverage left it exposed. Goldman Sachs, a major lender, demanded repayment, prompting the rapid fire sales that triggered Citadel’s intervention.

Citadel’s involvement was framed as “crisis capital” provision, a role the firm has played in past distressed-asset situations such as Amaranth, Enron, and Sowood Capital Management. The firm’s “preternatural ability” to detect trouble and supply timely funding was highlighted by market observers.
