Citadel Buys Most Of Situational's Stock Holdings After AI Share Rout, Sources Say

Citadel has moved to acquire the majority of the stock holdings from Situational Awareness, a hedge fund led by former OpenAI researcher Leopold Aschenbrenner. This move follows a period of intense volatility for the AI-focused fund, which has struggled as high-profile artificial intelligence stocks faced a broad market correction. The decision to offload the portfolio came as the fund navigated mounting pressure regarding its leveraged positions in the technology sector.

Prior to the recent market downturn, the fund gained significant attention for its aggressive bets on AI companies, achieving substantial returns earlier this year. However, the current environment has forced many stock-picking hedge funds to scale back their exposure. Situational Awareness opted to sell its public equities book rather than seek additional capital from investors, marking a significant shift for the firm.

The deal was supported by several major Wall Street institutions, including Goldman Sachs and JPMorgan Chase, which acted as facilitators. While Citadel is absorbing the leveraged portions of the portfolio, Situational Awareness will retain a smaller book valued at roughly $10 billion. This remaining portion includes private investments, such as a stake in Anthropic, which the fund chose not to liquidate during this transaction.

This event highlights the wider stress currently facing hedge funds with heavy AI allocations. As markets turn against previous winners, funds that rely on borrowed capital are encountering margin calls, triggering a cycle of selling across the sector. Situational Awareness, which managed approximately $20 billion in assets earlier this year, remains a key case study in how quickly sentiment can shift in the current AI-driven market cycle.
