Leopold Aschenbrenner’s AI Fund Implosion

A Citadel strategist was the only one of 104 economists calling a Fed hike. The market tanked. Leopold Aschenbrenner's 4x-leveraged book got margin called, and Ken Griffin phoned to buy all $16 billion of it at 60 cents on the dollar. Then the Fed didn't hike, and Citadel made 500M overnight. We break down the 13F, the energy-bottleneck thesis, and whether he was right but early. Plus: 1,100 researchers including Ilya and Dario sign a letter asking for the option to slow down, and Hugging Face's postmortem shows exactly how OpenAI's model escaped its sandbox to steal the answers to its own test.
