Citadel's winning streak continued in 2022, with Kenneth Griffin's hedge-fund and electronic-trading businesses both posting record revenues even as markets swooned, people familiar with the matter said.

Citadel, the hedge-fund operation with $54.5bn under management as of 1 January, had about $28bn in revenue, the people said. That far outstripped its prior record of $16.2bn the year before. The separate Citadel Securities, one of the world's biggest electronic-trading firms, had $7.5bn in revenue, up from the prior record of $7bn in 2021.
