Citadel acquired the entire public equity portfolio of Situational Awareness LP, the AI-focused hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, after margin calls triggered a forced liquidation. The fund’s concentrated positions in AI infrastructure names — including SK Hynix, CoreWeave, Nebius, Micron, and Bloom Energy — had fallen 35–47% in July, wiping out equity at approximately four times leverage. Prime brokers Goldman Sachs, JP Morgan, and Bank of America issued the margin calls, prompting a failed capital raise and unsuccessful negotiations with Millennium Management and Jane Street. Citadel stepped in, and news of the removal of a forced seller sparked a sharp rebound in AI infrastructure stocks, with the Nasdaq gaining 3.30% Thursday.
Crypto markets, by contrast, showed little reaction. Bitcoin traded around $64,155 — essentially flat on the day — while Ether held near $1,900. Total crypto market capitalization remained around $2.25 trillion. The episode highlights that while some AI infrastructure names have significant crypto mining operations (e.g., Core Scientific, TeraWulf), the selling pressure was equity-specific and did not spill into digital assets. The resolution of the margin call mechanics allowed AI stocks to recover faster than crypto, which trades around the clock and lacks the same concentrated forced-seller dynamics.
