Core Event: Citadel Purchases Bulk of Situational Awareness Public Portfolio
In early July 2026 the AI-focused hedge fund Situational Awareness was compelled to sell most of its public equity holdings to Ken Griffin’s Citadel after margin calls threatened solvency. The transaction, completed within 24 hours, transferred a public-stock book valued at roughly $10-20 billion, leaving the fund with a largely private-asset portfolio that still includes a stake in Anthropic.
Background & Context
Founder Leopold Aschenbrenner left OpenAI in 2024 and launched Situational Awareness that year, naming it after a viral essay on rapid progress toward artificial general intelligence. The fund’s thesis centered on AI-driven demand for data-center infrastructure, memory chips, and cloud services. Early backers included Stripe co-founders Patrick and John Collison, AI veterans Nat Friedman and Daniel Gross, and trading firm Jane Street.
Data & Statistics
- Peak assets: ~ $45 billion at the start of July 2026.
- Post-sale assets: $10 billion of public equities sold; remaining book estimated at $10-20 billion, primarily private stakes.
- July performance: Portfolio value fell 67 % in July 2026.
- YTD return: Up about 80 % despite July losses.
- First-half 2026 return: 439 % net of fees (Jan 1–Jun 30).
- Leverage: Up to 400 % on AI-themed bets.
- Key holdings impacted: SK Hynix, Sandisk, CoreWeave, Nebius, Bloom Energy, AMD, Oracle.
Official Statements & Responses
Aschenbrenner’s July 24 investor letter said rapid market moves and drying liquidity made risk-parameter compliance “progressively difficult.” He noted the fund had removed all leverage from its public book and would continue as a hybrid public-private vehicle. Citadel and Situational Awareness declined comment.
Criticism & Opposition
Observers warned the fund’s rise was built on excessive leverage. Jerry Diao, a Wall Street coach, said, “A lot of people saw this blow-up as a matter of not if, but when.” Critics highlighted Aschenbrenner’s limited investing experience prior to 2024.
Conflicting Reports & Gaps
Sources differ on the size of the public portfolio sold: CNBC cites about $10 billion, Bloomberg mentions $16 billion, and The Globe and Mail refers to “roughly $20 billion” before the sale. The exact timing and source of margin calls remain unverified.

What’s Next
Citadel has not disclosed its future handling of the acquired AI stocks. Aschenbrenner plans to seek additional capital beginning August 1 2026 and to focus on private-market positions, including a potential Anthropic IPO. Analysts note the episode underscores systemic risk of heavily leveraged, theme-concentrated funds.
