$45 Billion AI Fund Collapse Sparks Crypto Market Concerns

Leopold Aschenbrenner's $45 billion AI fund Situational Awareness collapsed in two weeks, losing three-quarters of its assets in late July 2026. The fund was forced to sell its entire public equity book to Citadel at a discount after prime brokers issued margin calls it could not meet.

The fund's positions in AI infrastructure names such as SK Hynix, CoreWeave, Nebius, Micron, and Bloom Energy fell between 35% and 47%, while the Philadelphia Semiconductor Index dropped 28.6%. The positions were leveraged at up to 400%, making them vulnerable to margin calls.

The prime brokers Goldman Sachs, J.P. Morgan, and Bank of America issued margin calls, which the fund attempted to address through a capital raise letter to existing investors, discussions with lenders, and negotiations with Millennium Management and Jane Street Group. However, these efforts failed, and Citadel eventually absorbed the public book at a discount.

The collapse has significant implications for the crypto market, as it highlights the dangers of extreme leverage and concentration in a single thesis. The story bears similarities to previous blow-ups in the crypto space, including FTX's downfall. Aschenbrenner's background in AI research and his connections to OpenAI and the FTX Future Fund add to the intrigue.

The Situational Awareness collapse also raises questions about Bitcoin's correlation with AI stocks. For most of 2026, crypto traded as a high-beta expression of the AI trade, but this relationship broke in July. Bitcoin barely moved when $797 billion came off the largest US technology stocks, and it rose when AI infrastructure names rebounded sharply.

The failure of Situational Awareness is a cautionary tale for investors and fund managers alike. Aschenbrenner's story serves as a reminder that leverage can be symmetrical, and even the most well-researched thesis can go wrong.
