When a high-profile AI book running heavy leverage starts cutting positions under broker pressure the forced selling can itself pressure the same crowded names further. That is how a correction turns into a cascade.
- Leopold Aschenbrenner’s Situational Awareness hedge fund got crushed in the AI and semiconductor sell-off.
- The fund was reported at around $20 billion in scale.
- It was up 439 percent net through the end of June 2026.
- July reversed those gains hard as AI and chip stocks sold off.
- The fund is dumping trades according to reports citing CNBC’s David Faber.
- Prime brokers are on them over margin requirements and position cuts.
- Reports say the fund was running roughly 4x margin on AI and semiconductor bets.
- That leverage turned the drawdown into a full-blown problem.
- Now they are seeking fresh capital from existing investors and lenders.
- Some investors are being offered the chance to buy assets out of the portfolio.
- Oracle and AMD fell about 20 percent in July.
- Other holdings like Nebius, Bloom Energy and Sandisk dropped even harder.
- An investor letter admitted the pain, especially in Asia, then tried to spin the sell-off as a buying opportunity.
