Sources: AI-focused hedge fund Situational Awareness sold the bulk of its stock portfolio to Ken Griffin's Citadel after suffering deep losses

The highflying hedge fund run by Leopold Aschenbrenner is in crisis mode after AI-related bets sank — Situational Awareness …

Wall Street Journal 2026-07-31

Context & Ripple Effects

Situational Awareness had rapidly accumulated assets as an AI-focused fund, with earlier coverage placing it above $20 billion in assets under management before the recent downturn. Reports then said it was seeking capital after heavy losses during the AI selloff, framing the portfolio sale as a liquidity response rather than a routine repositioning.

The reported exit from public equities follows coverage that the fund grew to roughly $45 billion before losses took hold. Its reported $5 billion Anthropic stake and plan to continue as a private investment firm mean the episode is a retrenchment of one investment channel, not necessarily a full shutdown.

First-order effects

Situational Awareness converts most of its public-equity exposure into cash to address reported margin calls, while Citadel takes over the acquired stock portfolio.
The fund’s investors and counterparties face a materially smaller, less liquid strategy centered on private holdings after the public-book sale.

Second-order effects

The unwind puts AI-theme hedge funds under sharper scrutiny from investors and lenders over leverage, liquidity terms, and the ability to withstand concentrated drawdowns.
Citadel gains a portfolio transferred under distressed conditions, while public-market exposure to AI-linked companies shifts from a specialist fund to a diversified multi-strategy buyer.

Third-order effects

If similar funds have to reduce risk during AI-market reversals, capital may concentrate in managers with deeper liquidity and more resilient financing rather than in narrowly themed vehicles.
The episode highlights how private AI investments can remain exposed to public-market volatility when fund-level leverage and liquid public positions are used to finance a broader AI thesis.

The trend: AI investing is becoming increasingly financialized, with concentrated thematic bets tested by the mismatch between volatile public markets and illiquid private holdings.

Citadel Securities publicly called for a surprise hike two days before the FOMC. The Fed held. These guys liquidated leopold and scooped up his port at the bottom. 😂

When you use this kind of leverage you didn't come here to not scramble for margin calls at least once. Full ‘we know what we signed up for’ protocols in place.

In a sense, this is the second big blowup for Leopold in a few years, the first having been his involvement with FTX (though that was on the firm's philanthropic side)
