Situational Awareness hedge fund forced to unwind after AI infrastructure bets collapse — Citadel steps in

Situational Awareness Forced to Unwind After AI Infrastructure Bets Crater

Leopold Aschenbrenner's AI-focused hedge fund has been forced to liquidate its entire public stock portfolio after steep losses on concentrated infrastructure bets, with Ken Griffin's Citadel acquiring the positions in what amounts to a fire sale.

The fund, built around Aschenbrenner's 2024 thesis that rapid AI progress requires massive buildout in chips, memory, power, and compute infrastructure, held 4x leverage across concentrated long positions in Nebius, Micron, and CoreWeave while shorting software names like Adobe. As AI infrastructure stocks plunged in recent weeks—before rebounding sharply today—the combination of leverage and margin pressure forced the unwind.

Citadel's deal to acquire the portfolio appears to value the holdings at a significant discount, though the exact haircut remains unclear. The spread between what's being reported as "pennies on the dollar" and actual recovery varies in the narrative: some commentary suggests 5-10% recovery, but the acquisition may actually be closer to 50-80% of book value.

The speed of the collapse matters here. The fund sat at approximately $4.5 billion AUM around the end of June or beginning of July. The blow-up happened in days. One minute there's a letter to LPs framing market weakness as a buying opportunity; the next, forced liquidation. This mirrors the velocity of FTX and SVB—when leverage is involved, things move in hours and overnight, not months. Venture capital collapses can drag on for years because equity absorbs losses gradually. Leverage-fueled forced selling compresses the entire cycle.

The frustration among observers is that this doesn't read as a referendum on AI or the infrastructure build thesis itself. The fund faced a perfect storm: oil price moves, inflation signals, Federal Reserve rate uncertainty, and retail froth layered on top of what had become an oversized trade. Aschenbrenner's core bet on compute and power infrastructure may be sound, but timing, leverage, and macro conditions created the conditions for forced selling regardless of the long-term thesis.

Aschenbrenner, a former OpenAI researcher who rose to prominence after publishing his essay series "Situational Awareness," is also reportedly engaged to Dario Amodei's chief of staff at Anthropic. He previously lived through FTX's collapse as part of the Future Fund team, which he left when the fraud emerged.

The fund's failure to survive even a short drawdown—despite its high-profile LP base of founders and investors with deep AI exposure—underscores a basic mathematical reality: at 150% volatility with variance drag alone running 113% annually, the risk of ruin was roughly even money over the fund's lifespan. Ruin wasn't unlikely. It was a coin flip.
