Aschenbrenner’s meteoric rise has been almost as exceptional as his latest fall.

Dubbed the “Nostradamus of AI,” Aschenbrenner met his fiancée Avital Balwit while the pair labored at FTX. She now serves as chief of workers to Anthropic’s CEO.
Now, instead of celebrating one of the greatest weeks of his life solely as a newlywed, the AI wunderkind is also making an attempt to rebuild one of the most spectacular hedge fund collapses in latest reminiscence.
