An AI Hedge Fund Learned the Oldest Lesson in Finance

CNN tells the remarkable story of Situational Awareness, an AI-focused hedge fund founded in 2024 by former OpenAI researcher Leopold Aschenbrenner.

Aschenbrenner believed artificial intelligence would drive global investment returns over the next decade. The fund grew from several hundred million dollars to more than $20 billion in assets, helped by enormous returns, additional investment and aggressive borrowing. Aschenbrenner had become known as the “Nostradamus of AI,” despite having no previous experience managing money.

Then the AI trade moved against him.

The fund lost approximately 67 percent of its portfolio value during July as chipmakers, cloud providers and other AI-related investments declined. Its use of leverage amplified those losses and created pressure from lenders, eventually forcing Situational Awareness to sell most of its public stock portfolio to Citadel. Aschenbrenner later told investors that the fund had come closer to permanent capital impairment than he considered acceptable.

The scale of the collapse is extraordinary, but there is an important qualification: the fund was still reportedly up approximately 80 percent for 2026 after the July loss. This was not a simple case of every investment becoming worthless. It was a liquidity crisis caused by concentrated positions, borrowed money and a market moving too quickly for the fund to wait for a recovery.

Being correct about a long-term technology trend does not mean every company associated with that trend is correctly valued. It also does not mean the market will move according to your preferred timeline.

Leverage removes the ability to wait.

This does not prove that artificial intelligence has no economic future. It does demonstrate how much speculation has accumulated around the companies supplying the current AI boom. When investors borrow heavily to buy the same crowded group of stocks, even a temporary decline can trigger margin calls, forced sales and further declines.

Situational Awareness may be an isolated failure rather than the beginning of something systemic. But other funds reportedly held many of the same investments, and that makes this more than a story about one inexperienced manager who became famous while his bets were working.

The AI bubble can be real while the underlying technology remains important. We still do not know which companies will survive, which valuations can be justified or how much borrowed money is holding the current market together.
