Citadel, the hedge fund led by Ken Griffin, quickly sold off approximately 80% of the public stock portfolio it had recently acquired from Situational Awareness, the AI-focused hedge fund. This rapid divestment occurred shortly after Citadel purchased the distressed assets from Situational Awareness, which was forced to sell due to heavy losses and margin calls. The move allowed Citadel to profit significantly from a short-lived market rebound in certain AI-related stocks.

Situational Awareness, founded by former OpenAI researcher Leopold Aschenbrenner, had accumulated over $20 billion in assets under management but faced severe downturns in its AI-focused public equity positions. Its portfolio included companies in the AI supply chain such as SK Hynix, Sandisk, Bloom Energy, and Nebius Group, all of which had experienced significant declines. Citadel acquired these holdings at a discounted rate, primarily purchasing the portion of Situational's public portfolio that was financed with borrowed money.

This strategic acquisition and subsequent rapid sale contributed to Citadel's strong performance in July. Its flagship Wellington fund returned 5.9% for the month, and its equities fund saw an impressive 14.2% gain, marking its best-ever month. This quick turnaround highlights Citadel's ability to capitalize on market dislocations and distressed asset sales, turning a challenging situation for one firm into a profitable opportunity for itself. Situational Awareness still retains its private investments, including a stake in AI giant Anthropic.
