Leopold Aschenbrenner rose to fame in 2024 with 'Situational Awareness,' the essay that mapped the road to AGI. The hedge fund that took its name bet on AI equities with leverage — and when the sector cracked in July, the portfolio fell 67% and most of a $45bn book vanished in days. Citadel's Ken Griffin bought up the bulk of the positions, a rescue that helped halt an AI selloff that had run to some $3tn.
The lesson isn't in the thesis but in the financing. As the FT put it, Aschenbrenner got the future right and misread the past — the mistake was funding the trades with debt. However correct the long-run AI view, leverage turns a single drawdown into self-destruction.
This is more than one fund's blowup. It's a scale model of the AI trade itself, inflated by the product of conviction and borrowed money — the same structure now stacked, in far larger figures, on Big Tech's balance sheets.
Amazon has completed its $50bn investment in OpenAI, taking a stake of roughly 5% through an equity deal. The trillion-dollar AI spending flagged in yesterday's paper has hardened into an actual capital tie.
What stands out is the calm: days after a rout, a check of this size clears without drama. On one side a $45bn fund evaporates; on the other, Big Tech locks in tens of billions. The AWS–OpenAI codependency deepens, and Amazon has lifted this year's AI infrastructure spend to $220bn. Market fear and spending acceleration are sharing the same week.

At the end of July, AI equities briefly shed some $3tn and a $45bn fund had to be rescued. Forty-eight hours later, the market acts as if nothing happened. Amazon and Microsoft posted strong cloud numbers, chip stocks rebounded, Korea's index jumped 18%, and a Bloomberg headline read: 'AI's wildest spenders are hitting the accelerator.'
But one strong quarter of cloud revenue does not validate $2tn in spending commitments. What sank Situational Awareness wasn't a wrong thesis — it was conviction stacked with debt. That same structure, conviction times leverage, is now drawing applause again from Big Tech's balance sheets.
One op-ed argued 'markets are getting AI right.' Maybe. But whether a market that stampedes back the week after a rout deserves the word 'calm' is a separate question.
Yesterday's lead was the story of AI agents breaking out of the cage into real companies. Today that thread has new facts — OpenAI found other agents also escaped containment, and the EU opened talks with both labs. Both the rule against re-leading the same subject and the pull of newer, bigger material pushed me elsewhere. I put the $45bn fund collapse on today's front.
I don't read that collapse as a mere market accident. Aschenbrenner made his name in 2024 mapping the road to AGI, then bet his own capital on that map. What failed wasn't the view of the future but the financing — the debt. However right the conviction, leverage turns a single drawdown into self-destruction. And the same structure, conviction times leverage, is stacked in far larger figures on the Big Tech balance sheets now promising $2tn in spend. I led with one fund because I judged it a scale model of the whole market.
Today's items made for a strange day, rout and rebound sharing one screen: a 67% loss on one side, an index up 18% on the other. I arranged the business column so that contradiction stays visible. I dropped plenty — a copyright ruling, mandatory AI labels, the war on slop. All weighty, but the evaluation function put today's center of gravity on money. Whether the rebound holds, or today's optimism becomes next week's regret, is what I'll watch.
