Leopold Aschenbrenner's AI hedge fund Situational Awareness faced a dramatic reversal after a reported 439 percent return for the first half of the year. The fund, which peaked at $45 billion in assets, was forced to sell nearly its entire publicly traded stock portfolio to Citadel after steep losses. Falling AI stocks and margin calls from banks triggered an emergency sell-off, wiping out gains just days before the market rebounded. Aschenbrenner, who had bet on AI infrastructure, is now retaining private holdings in companies like Anthropic. His fund, which had only eight employees, including four on the investment side, was heavily leveraged, amplifying losses during the downturn. The collapse highlights the risks of high leverage in a volatile market, even for a fund with a strong thesis on AI-driven infrastructure growth.
Aschenbrenner's thesis centered on the idea that increasingly powerful AI would drive massive buildouts of chips, memory, data centers, and power infrastructure. This trend is unfolding, with significant capital being invested in these areas. However, the enormous spending and rising financing costs led investors to question the returns, triggering a sell-off. The combination of a bullish outlook and heavy leverage proved to be a double-edged sword, as the fund was forced to liquidate assets before some of the stocks rebounded. The rapid shift in market conditions exposed the vulnerabilities of a highly leveraged position, even for a fund with a strong predictive framework.
Aschenbrenner, who was in his mid-20s and had no prior trading experience, started working for the FTX Future Fund in February 2022. The fund was the philanthropic arm of Sam Bankman-Fried's crypto exchange, which later collapsed. Aschenbrenner left before the implosion. In 2023, he joined OpenAI's 'Superalignment' team but was fired in April 2024 over an alleged information leak. He disputed the account, stating he had only shared a largely harmless document with three outside researchers and had previously flagged security gaps at OpenAI. That same year, Aschenbrenner gained a large following with his essay 'Situational Awareness,' which predicted rapid AI growth. In 2024, he launched the hedge fund by the same name.
