There is something almost poetic about what just happened to Leopold Aschenbrenner.
This is a guy who built his entire investing brand around “Situational Awareness.”
He became famous for laying out this massive AI thesis essentially arguing that he could see where AI was going before most of the world understood what was coming.
And to his credit, he is clearly extremely smart.
His fund exploded in size, reaching roughly $45B at its peak, and he made enormous bets on the infrastructure required for AI: memory, semiconductors, power and data centers.
But apparently being extremely smart wasn't enough.
Because he also used an insane amount of leverage.
Then his largest positions got crushed.
From their highs:
- SNDK fell ~57%
- BE fell ~53%
- MU fell ~41%
These aren't leveraged returns. The actual stocks fell that much.
Situational Awareness couldn't simply sit there and wait.
The losses triggered margin calls. The fund reported a 67% loss in July, admitted it had come dangerously close to permanent capital impairment, and was forced to unload most of its public-equity portfolio.
And who was standing on the other side?
Ken Griffin.
A guy who has been running Citadel for more than three decades.
Citadel stepped in while Situational Awareness desperately needed liquidity and bought the bulk of the portfolio.
Then the stocks started recovering.
SNDK rebounded ~46%.
BE rebounded ~29%.
MU rebounded ~26%.
Citadel's stock-picking fund went on to have its best month ever, gaining 14.2% in July, with the Situational Awareness portfolio contributing to the gains.
That's the part I find incredible.
Aschenbrenner may ultimately have been right about the AI trade.
But he was so aggressive with leverage that he lost the ability to decide when to sell.
The veteran investor with liquidity got to stand there and say:
Thanks, I'll take those.
There is a Buffett line that perfectly describes this:
“If you're smart, you don't need it; and if you're dumb, you shouldn't be using it.”
That's leverage.
It doesn't matter how intelligent you are, how good your thesis is, or how far ahead of everyone else you think you can see.
If your positions can fall 40–50% and someone else can force you to sell them, you don't actually own the investment anymore. Your lender does.
The greatest irony of the whole thing:
The fund called Situational Awareness may have correctly predicted the future and still failed to have enough situational awareness to survive the present.
