Citadel has successfully unwound more than 80% of the risk associated with its recent acquisition of assets from the AI hedge fund Situational Awareness, according to a letter Ken Griffin, the firm's CEO, sent to clients Friday. In the three weeks since the purchase, Citadel executed over 100 block trades totaling more than $4 billion, indicating a swift and profitable repositioning of the acquired portfolio.
The assets were purchased from Situational Awareness, a fund managed by 25-year-old Leopold Aschenbrenner, who had amassed $20 billion by heavily investing in artificial intelligence. Aschenbrenner's fund held substantial stakes in companies like SanDisk and Micron, alongside short positions in software stocks. However, market volatility in late July led to a forced liquidation of these public stock positions by Aschenbrenner to Citadel in a rapid sale.
Griffin highlighted Citadel's proactive approach during market disruptions, stating in the letter, "Over our nearly thirty-six-year history, we have prided ourselves on being front-footed and proactive during periods of market dislocation." He emphasized Citadel's capability to manage such a large-scale transaction within a tight timeframe. The acquisition was reportedly made at a discount of approximately 10%, with Citadel anticipating a market rebound to facilitate profitable resale of the positions.
Since Citadel's intervention, shares of SanDisk and Micron have shown signs of recovery, aligning with Griffin's strategy. The significant volume of trades executed by Citadel suggests substantial profits were realized from this strategic acquisition. The firm's flagship multistrategy Wellington fund also reported a 5.94% return in July, its strongest monthly performance since 2022.
Situational Awareness had attracted investments from prominent figures in finance and technology, including executives from Greenoaks, D1 Capital Partners, and former Tiger Global Management personnel. Some investors had reportedly cautioned Aschenbrenner about the aggressive nature of his AI-centric strategy. Frustration had also been growing among certain investors due to Situational Awareness's less frequent disclosure of returns compared to industry standards.
The fund's aggressive use of leverage to finance its AI bets proved risky. The downturn in AI and tech stocks over the summer led to significant losses for Situational Awareness, prompting some investors to seek withdrawals. Notably, Jane Street, a major investment bank and an investor in Situational Awareness, reported a $15 billion loss in July following the fund's difficulties.
Despite these challenges, Aschenbrenner had previously informed investors that Situational Awareness remained up 80% for the year, following an earlier report of over 400% gains in the first half of 2026. The recent maneuvers by Citadel suggest a successful navigation of the volatile AI investment landscape.
