A hedge fund heavily exposed to AI infrastructure was forced to liquidate its public positions after heavy losses, in a market shaken by rates and volatility.
The fund Situational Awareness, founded by Leopold Aschenbrenner, had to unwind its entire listed portfolio after a rapid drop in its positions. Margin calls pushed prime brokers to demand cash, accelerating the sell-off. Citadel, led by Ken Griffin, reached an agreement to acquire these assets, temporarily stabilizing battered stocks.
The strategy was based on a thesis of massive expansion in AI capacity, with concentrated positions in Nebius, SanDisk, Micron, and CoreWeave, while shorting software names like Adobe. The recent pullback in infrastructure-related stocks, followed by a technical rebound, caught the fund off guard.
The episode illustrates the brutality of leveraged markets. Within days, rumors and then forced selling were enough to trigger a downward spiral, comparable to other recent crises. Unlike venture capital, where adjustments unfold over years, the liquidity of public markets accelerates outcomes.
Tensions were amplified by monetary policy expectations. Fears of a surprise rate hike by the Federal Reserve weighed on growth stocks. Although the policy rate was unchanged, mortgage rates reached 6.66%, a one-year high, fueling risk aversion.
Quantitative analyses تشير to a risk of ruin near 50% for such a concentrated and volatile strategy. Annual “variance drag,” estimated above 100%, made the path extremely fragile, even independent of the validity of the AI thesis.
After the acquisition announcement by Citadel, several portfolio stocks jumped by more than 10% in a single session. Despite this bounce, many remain significantly down over a month, confirming the correction goes beyond a one-off shock.
Leopold Aschenbrenner, a former OpenAI researcher, became known for an influential essay on the rise of AI. This vision attracted investors willing to accept high risk to capture a potentially major industrial transformation.
This episode highlights the fragility of concentrated, leveraged strategies in an uncertain macro environment, where even strong convictions about AI are not enough to prevent rapid, systemic losses.
