Leopold Aschenbrenner earned recognition in the investment landscape by advocating for the transformative power of artificial intelligence. However, the reality turned grim in July 2026 when his hedge fund, Situational Awareness, experienced an alarming 67% loss in value in just one month.
#What led to the downfall of Situational Awareness?
The significant losses prompted Aschenbrenner to liquidate the entire public equities portfolio of his fund, which was acquired in a block trade by Ken Griffin's Citadel. In his communication to investors, Aschenbrenner openly acknowledged the disappointment of the month’s performance. The losses primarily affected AI infrastructure and semiconductor stocks, which were central to his investment strategy.
#How did the failed Anthropic deal compound the issues?
Compounding the difficulties was Situational Awareness's involvement in a stalled $3.5 billion share sale of Anthropic, a competitor in the AI safety sector. The deal withdrawal arose from a liquidity crisis that the firm faced, further underscoring its precarious position.

#What does Aschenbrenner's past at OpenAI signify?
Previously, Aschenbrenner served as a researcher at OpenAI, where he nurtured a firm belief in AI's potential to disrupt industries. This conviction led him to design an investment thesis focused on AI infrastructure, culminating in the establishment of his hedge fund. Despite the recent turmoil, Aschenbrenner remains determined to keep the fund operational, considering the loss as a setback rather than a conclusion.
#What should investors in AI funds takeaway from this?
For investors focusing on thematic funds, especially those concentrated in the AI sector, the recent events indicate the need for rigorous examination of their investment strategies. One should inquire about position sizing, hedging practices, and liquidity management among fund managers. A 67% drawdown in a single month raises questions about adequate risk controls and whether they were effectively implemented.
The failed Anthropic transaction adds to the caution. With private market holdings typically illiquid, they can weigh heavily on a fund's balance sheet during a liquidity crunch. Any fund that maintains substantial private AI investments alongside leveraged public positions risks repeating the missteps encountered by Situational Awareness.
