Analysis
Situational Awareness, the AI-focused hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, was forced into a sweeping unwind of its public stock positions after a sharp reversal in AI-infrastructure momentum trades triggered margin calls the fund couldn't meet without selling. Assets under management fell from roughly $45 billion to about $10 billion within weeks -- one of the more dramatic and least-discussed casualties of this AI cycle's volatility so far.
The mechanics matter as much as the headline number: the fund reportedly ran leverage as high as 400%, holding long positions in AI-infrastructure names like SK Hynix and neocloud CoreWeave against short positions in software names it expected to underperform AI-native competitors. When semiconductor stocks reversed sharply, both sides of that book moved against the fund at once, and leverage turned a painful drawdown into a forced liquidation rather than a survivable one.
“One detail is worth separating from the rest: the fund kept its Anthropic shares even while liquidating nearly everything else in its public portfolio.”
One detail is worth separating from the rest: the fund kept its Anthropic shares even while liquidating nearly everything else in its public portfolio. Anthropic sits in the fund's private, illiquid holdings rather than its leveraged public book, meaning Aschenbrenner treated it as a distinct, higher-conviction position worth preserving under duress -- a decision that draws a sharp line between genuine long-term thesis and the leveraged trading structure that actually got liquidated.
For LPs and allocators evaluating any AI-themed fund right now, the lesson isn't about Aschenbrenner's macro call, which may well still prove correct over a longer horizon -- it's that a correct multi-year thesis provides no protection against a leverage-driven liquidation if the trade's structure and timing are wrong, even briefly. Underwriting an AI-adjacent fund manager on thesis alone, without asking directly about leverage levels and margin exposure, is the exact gap this episode exposes.
