Situational Awareness, the 24-year-old Leopold Aschenbrenner's AI-focused hedge fund, lost two-thirds of its value in a single month. The fund that posted 439% returns through June and ballooned to $45 billion in assets under management was forced to sell roughly $16 billion in equities to Citadel at a 10% discount just to cover margin calls.
The collapse happened fast. A broader downturn in AI infrastructure stocks flipped the script on leveraged bets that had made Aschenbrenner look like a genius. SK Hynix, Nebius, Micron, the semiconductor names that fueled the 439% run, reversed hard. Bank of America, Goldman Sachs, and JPMorgan demanded cash. By July 30, the liquidation was done.
The use trap
The fund's strategy was straightforward but aggressive, combining long positions in AI hardware with short plays in software stocks. When the entire AI sector moved against the long side at once, the shorts couldn't offset the damage. Citadel, the mega-fund known for swooping into distressed situations, picked up the entire $16 billion portfolio at a steep discount. The AI sector itself had already shed roughly $3 trillion in market value during the downturn.
What's left
Situational Awareness didn't die completely. The fund still holds about $10 billion, largely in private positions including a stake in Anthropic, and remains up roughly 80% for the year. But the message landed hard: even with a small team managing more capital than firms take decades to accumulate, use can destroy you in weeks. A 24-year-old managing $45 billion through concentrated bets on a single sector had no margin for error.
