# Ken Griffin

## Ken Griffin

**Type:** Person  
**Role:** Billionaire founder and CEO of [[entity-citadel]] and Citadel Securities.

### Role in This Vault

Mentioned by [[entity-jay-roberts]] as a **major driver of capital into the Brickell market**, where Griffin is building a new headquarters for [[entity-citadel]]. Griffin's Miami relocation is part of the broader post-COVID financial-firm migration that produced the office-rent boom underpinning [[concept-office-suite-condos]] — and which remains an open empirical question in [[question-office-rent-sustainability]].

Griffin's presence functions in the conversation as **shorthand for the demand-side story** powering Roberts's market thesis.
