Alphacution Press: The Mysterious Billionaire Boss at Jane Street Smashing Trading Records

Alphacution quoted in Bloomberg‘s December 1, 2025 article ($) by Katherine Doherty on how Rob Granieri, the secrecy-loving co-founder of the trading powerhouse, Jane Street Group, is “raking in money faster than he can spend it on Burning Man, his own casino and, unwittingly, an African coup.”

“I wouldn’t recognize him walking down a street,” said Alphacution’s Paul Rowady, a researcher who digs into firms like Jane Street. “Congratulations to Rob Granieri: Influence and anonymity is a very rare combination.”
