Did the castle hunt the 25-year-old stock god Leopold? At the end of June, Leopold Aschenbrenner's fund achieved a net return of 439% for the year. A month later, he handed over the majority of his approximately $16 billion public stock portfolio to Ken Griffin's Citadel. This is the cruelest lesson on Wall Street in 2026: looking at the future doesn't mean you can live into it. Leopold is not a traditional fund manager. He once studied superintelligence at OpenAI and published a 165 page article titled 'Situational Awareness' in 2024, predicting that AGI may arrive around 2027, with computing power, electricity, storage, and data centers becoming the scarcest resources. Subsequently, he established a fund with the same name and directly turned this article into an investment portfolio. He did not simply heavily invest in Nvidia, but instead bet on the physical bottlenecks that AI expansion must pass through: Bloom Energy、CoreWeave、Applied Digital、Core Scientific、IREN、SanDisk， And a group of power, storage, and computing infrastructure companies. This logic was once astonishingly accurate. The disclosed US securities position of the fund increased from approximately $255 million at the end of 2024 to $5.52 billion at the end of 2025; In the first quarter of 2026, the declared value of 13F reached 13.68 billion US dollars. By the end of June, the cumulative return of the fund has reportedly exceeded 1500%, with a management scale of over 20 billion US dollars. Leopold is therefore known as the 'AI stock god'. But his combination is far more dangerous than 'heavy warehouse AI'. Of the $13.68 billion in 13F, approximately $8.4 billion is from Nvidia AMD、 The nominal value of put options for Broadcom, TSMC, Oracle, and semiconductor ETFs. That is to say, he is long on storage, power, and new computing infrastructure while hedging against crowded semiconductor and software companies through options or short positions. When the market operates according to expectations, bulls, bears, and leverage can make money simultaneously. When the market suddenly reverses, it may also strike the net asset value from three sides. In July, SanDisk plummeted by over 50% in a single month, and AI infrastructure stocks such as SK Hynix, Micron, and CoreWeave experienced significant pullbacks; South Korea's leveraged trading concentration closed positions, and KOSPI fell nearly 40% from its peak at most. At the same time, the rebound of some software stocks has also hit the short positions of funds. On July 24th, Leopold also stated in an investor letter that this round of decline has created the most attractive investment opportunity since early 2025, and invited investors to raise additional funds. A few days later, the question was no longer whether these stocks would rise in the future, but whether the fund could sustain their rise. Goldman Sachs、 Morgan Stanley, Bank of America, Citigroup and other prime brokers participate in portfolio disposal. Situational Awareness faces two options: immediate acquisition of new capital or surrender of public stock positions. Citadel ultimately took up its main position supported by leveraged financing from securities firms in less than 24 hours. It is rumored that the peak value of the fund has reached 45 billion US dollars, and the leverage is close to 4 times. Leveraging not only amplifies returns, but also the speed at which the market forces you to give up. On July 27th, Citadel Securities publicly predicted that the Federal Reserve may unexpectedly raise interest rates by 25 basis points, even calling this shock a "cleaning event" that forces the market to reprice. Three days later, Citadel bought Leopold's stock portfolio. The timeline is indeed like a carefully designed hunt. In 2006, Amaranth suffered a loss of approximately $6 billion due to leveraged natural gas trading, and Citadel also took over its energy portfolio during the crisis, earning huge profits from it. Ken Griffin's greatest skill is not predicting who will sell out, but having the capital, risk management system, and trading ability to take over the entire portfolio when others must sell. Ironically, after Leopold relinquished his position, the semiconductor index rose 8.2% in a single day, Micron rose 18%, AMD rose 13%, and SanDisk rose about 26%. This cannot prove that Citadel was bought at the absolute bottom, but it constitutes the cruelest picture: As soon as the forced seller left, the assets he believed in began to rebound. Situational Awareness has not gone bankrupt. The fund still retains approximately $10 billion in assets, including billions of dollars worth of Anthropic equity. Leopold may not have misjudged AI either. What he really lost was waiting for his right ability. Investment ability is never just about research and judgment, but also includes positions, financing, liquidity, and how long to survive in the worst-case scenario. Leopold sees the future of AGI. Citadel saw his balance sheet. In the end, what the castle bought was not just stocks, but a time that the forced seller no longer had the ability to continue owning.
