Ken Griffin

Founder & CEO, Citadel~$40B+

Multi-strategy machine

Edge decays, so build a machine that manufactures it continuously: the best talent, the best data, the best infrastructure, across many uncorrelated strategies at once. Risk is managed centrally so no single idea can sink the ship.

The tax playbook

Editorialstrategies widely reported around Griffin — never tax advice

The Florida move

Relocating Citadel from Chicago to Miami took him from a high-tax state to zero state income tax — on one of the largest earned-income streams in finance.

Art and philanthropy

Museum-scale giving and loans of appreciated works carry meaningful deduction value.
