Data: Leopold Aschenbrenner ' s AI Fund return at the beginning of the year to date is about 80 per cent

According to a letter sent to investors on Thursday, 31 July, a hedge fund managed by Leopold Aschenbrenner, a former OpenAI researcher, reported a significant decline in the value of the portfolio in July due to AI stocks, which fell by 67 per cent. According to informed sources, this Aschenbrenner-managed hedge fund, which focuses only on AI, has sold most of its equity portfolio this week to Citadel, a billionaire, Ken Griffin, and has settled most of its open stock holdings. In a letter to investors, Aschenbrenner wrote: “We are closer to permanent capital losses than we can accept.” He added that although the company had finally found a solution, it had never intended to put itself in such a situation. In his letter, he said, “We are disappointed this month.” The Wall Street Journal first disclosed the content of the letter on Thursday evening. However, as indicated in the letter, the Fund ' s cumulative rate of return since 2026 has remained at 80 per cent, owing to the considerable gains made previously. Aschenbrenner also stated that the Fund remained “very optimistic” about the current portfolio, arguing that, despite the significant decline in equity prices, the fundamentals of the related assets continued to improve。
