The majority of the portfolio of the fund run by the AI stock guru has been sold, with Ken Griffin’s Citadel as the buyer.

According to people familiar with the matter, Situational Awareness, an AI-themed hedge fund founded by 25-year-old rising Wall Street AI stock prodigy and former OpenAI researcher Leopold Aschenbrenner, has sold most of its stock portfolio to Ken Griffin’s Citadel after incurring massive losses. The fund had recently been seeking buyers for its holdings and attempting to raise new capital. As of the end of the first quarter, Situational Awareness’s top holdings included Nebius, SanDisk, Micron, and CoreWeave, all of which have seen their stock prices drop by more than 35% this month. Ken Griffin is a renowned American billionaire hedge fund manager who founded Citadel in Chicago in 1990 and has served as its founder and CEO ever since. Citadel is one of the world’s largest and most successful hedge funds, managing hundreds of billions of dollars in assets and employing a multi-strategy investment approach covering equities, fixed income, commodities, quantitative trading, and more. Its subsidiary, Citadel Securities, is one of Wall Street’s most important market makers, holding a dominant market share in U.S. stock trading. Griffin is known for his shrewd trading style, rigorous risk management, and massive influence in the hedge fund industry, consistently ranking among the world’s wealthiest hedge fund managers. Earlier reports noted that the so-called "AI stock prodigy’s" fund had liquidated all publicly listed stock assets, initiating a gradual wind-down.
