AI Stock Bets Lead to Hedge Fund Collapse

Leopold Aschenbrenner’s hedge fund, Situational Awareness, collapsed in July following significant, highly leveraged investments in AI stocks such as SanDisk and Micron. The fund, which once managed an over $20 billion US stock portfolio, saw a dramatic 67% decline in July.

Initial AI Stock Plays

Before its July collapse, Situational Awareness made substantial bets on AI-focused companies, with considerable holdings in key technology firms. The fund also adjusted its options strategy, indicating a heightened risk approach.

• Investments of $5.7 billion in SanDisk.
• Stakes of $5.6 billion in Micron.
• These constituted 56% of its over $20 billion US stock portfolio.
• Increased holdings in TSMC.
• Acquired $1.2 billion stake in Nebius.
• Reduced put options, suggesting higher risk.

Fund’s Dramatic Downturn

Despite an impressive track record since its inception, the highly leveraged portfolio of Situational Awareness faced a severe downturn. A sell-off in AI stocks triggered a rapid decline, leading to significant financial repercussions for the fund.

• Achieved a 1,000% gain since inception.
• Experienced a 67% decline in July.

Consequences and Market Reaction

The sharp market correction led to margin calls, forcing Leopold Aschenbrenner to divest most of his publicly traded stocks. These assets were subsequently acquired by Ken Griffin’s hedge fund, Citadel, amidst the fallout.

Shares of SanDisk and Micron initially saw significant drops in July following the broader sell-off. However, both stocks have since regained some value, as investors increasingly anticipate their pivotal role within the expanding AI infrastructure.
