AI Hedge Fund Situational Awareness Faces Margin Calls and Asset Sale After AI Stock Rout
7/30/2026, 8:10:40 PM
Core Event: Forced Unwind and Sale of Public Equities
Leopold Aschenbrenner’s hedge fund, Situational Awareness LP, was forced to liquidate a large portion of its publicly traded AI-related holdings after steep losses triggered margin calls. A “big chunk” of the fund’s AI stocks was sold to Ken Griffin’s Citadel hedge fund, according to people familiar with the transaction. The sale was executed amid negotiations with prime brokers—including Bank of America, Goldman Sachs and JPMorgan Chase—to meet margin requirements or orderly wind down positions. The fund retained its private stakes, notably a holding in Anthropic, while the public-equity book moved to Citadel.
Background & Context
Aschenbrenner, a former OpenAI researcher, left the company in 2024 after publishing an essay warning of an imminent AI superintelligence. He launched Situational Awareness that year, building the firm around the thesis that AI expansion would drive demand for chips, memory, data-center capacity and electricity. Early backers included Stripe co-founders Patrick and John Collison, former Y Combinator partner Daniel Gross, and onetime GitHub CEO Nat Friedman. Reports said assets under management surpassed $20 billion and returns earlier in the year exceeded 400 percent on a net basis.
Data & Statistics
- Key holdings: At the end of Q1 2026, the fund’s largest positions included Nebius Group, Sandisk, Micron and CoreWeave, each down more than 35 percent for the month. Nebius shares have fallen 48 percent from a peak last month, erasing roughly $35 billion of market value. Sandisk is down 56 percent in just over a month, and SK Hynix ADRs trade about 15 percent below the $149 listing price, closing at $126.79.
- Short positions: The fund’s bet against software companies such as Adobe moved sharply against it, adding to margin pressure.
Official Statements & Responses
- A spokesperson for Situational Awareness said reports that the firm was marketing its Anthropic stake were inaccurate.
- Representatives for Citadel and Situational Awareness declined to comment on the sale.
- The fund’s July 24 investor letter acknowledged exposure to the recent AI market downturn but framed the volatility as creating new investment opportunities.
Conflicting Reports & Gaps
- Asset size: Reports differ between a $45 billion valuation at the start of July and a $20 billion figure cited by the Financial Times.
- Performance metrics: The fund’s own letter suggests strong returns, yet Bloomberg and other outlets note that the high-leverage strategy amplified losses, and the exact magnitude of those losses was not disclosed.
- Private-vs-public exposure: While the public equity book has been largely sold, the status of the private Anthropic stake remains unclear, with some sources indicating ongoing marketing to prospective buyers and others stating the firm has not yet finalized a sale.
What’s Next: Capital Raising and Portfolio Restructuring
Situational Awareness is seeking fresh capital, engaging existing investors and lenders, and offering portions of its portfolio—including the private Anthropic stake—for purchase. Prospective buyers have expressed interest, though no definitive agreements have been announced. The fund appears to pivot toward a greater focus on private AI companies while maintaining a smaller public-equity footprint.
The situation underscores the heightened risk of leveraged bets on rapidly shifting AI valuations, a dynamic that has already prompted a broader pullback in AI-related equities across the Nasdaq 100 since its peak on June 2.
