Ed O’Reilly, the Global Head of the Client and Partner Group at multi-strategy hedge fund major Citadel is set to retire later this year, according to a report by Reuters citing an internal company memo.
O’Reilly, 57, has been instrumental in scaling Citadel’s assets under management from $26bn to $67bn since joining in 2015 from Capula Investment Management.
Overseeing relationships with pension funds, endowments and other institutional allocators, O’Reilly logged millions of air miles annually to meet clients across 25 countries. His tenure coincided with record inflows and headline-grabbing returns, including Citadel’s $16bn profit in 2022 – the largest annual gain ever by a hedge fund.
Firm veterans Andy Adams and Steve Valan have been promoted to co-head Citadel’s Client and Partner Group.
Founded 35 years ago by Ken Griffin, Citadel ended 2024 up 15.1% and is up 4% in the first seven months of 2025.
