Leopold Aschenbrenner's hedge fund Situational Awareness saw its portfolio value plummet by $30 billion (67%) in July, according to a letter sent to investors and seen by Reuters. The losses were driven by steep declines in AI stocks, prompting the fund to sell most of its stock holdings to Ken Griffin's Citadel.

The AI-focused hedge fund, run by former OpenAI researcher Aschenbrenner, unwound most of its public equities portfolio this week. In a letter to investors, Aschenbrenner acknowledged that the firm came 'closer to permanent capital impairment than is acceptable,' though he noted that the fund ultimately found a solution.

Despite the significant monthly loss, Situational Awareness remains up 80% for the year, according to the investor letter. The hedge fund has garnered a cult-like following among investors since its launch in 2024 due to Aschenbrenner's bets on the AI sector. However, a global selloff in chip stocks has revived fears that the AI boom may be losing steam.

The situation highlights the risks of leveraged bets in volatile markets. Hedge funds typically borrow heavily to increase market exposure and boost returns, but such strategies can unravel quickly when markets move against them. Aschenbrenner told investors that the hedge fund has removed all leverage from its portfolio after experiencing a significant drawdown in July.

According to CNBC, the fund's prime brokers, including Bank of America, Goldman Sachs, and JPMorgan Chase, have been working with Situational Awareness to meet margin requirements or reduce positions. The firm had been negotiating to sell its stake in Anthropic but it wasn't clear if that deal was finalized.

The unwind comes at an unfortunate time for Aschenbrenner, who is getting married this weekend, according to CNBC. The turmoil marks an early test of the investment thesis that made Aschenbrenner a prominent figure in AI investing circles. He built his fund on the idea that powerful AI systems would require vast expansion in chips, memory, data centers, and electricity generation.
