Summary

Aschenbrenner Warns

Leopold Aschenbrenner’s 2024 essay warned that compute, power and AI infrastructure will limit AGI, feasible by 2027.
The fund’s manager called the July tech-stock rout a buying opportunity.
He cited a potential Anthropic IPO and a June stake of about one-fifth of assets.
Despite a 1,000% gain, the fund’s volatility deters fresh capital, prompting Aschenbrenner to call it a long-term bet.

History

Historical Context

In 2007 John Paulson shorted subprime mortgages, earning billions, and in September 2008 Treasury Secretary Henry Paulson pushed the $700 billion Troubled Asset Relief Program to buy distressed mortgage-backed securities. The July 2026 Citadel purchase of $16 billion of tech stocks after margin calls mirrors those crisis-era capital reallocations and renewed regulatory scrutiny of hedge-fund leverage.
