Summary
Ken Griffin, founder and CEO of Citadel Advisors, is completing his real estate exit from Chicago with the sale of his final property in the city. According to Bloomberg, Griffin's last Chicago condo—a full-floor duplex penthouse at 800 N. Michigan Avenue in the exclusive Park Tower building—has gone under contract. The property, characterized as the "crown jewel" of Park Tower, is listed for $12.5 million on Zillow, reflecting a notable 20% markdown from its initial July 2025 asking price of $15.75 million.
This transaction represents the final chapter in Griffin's sweeping Chicago real estate divestment that began following Citadel's announced relocation of its global headquarters from Chicago to Miami in June 2022. Bloomberg reported that Griffin owned a portfolio of high-end Chicago properties over his tenure but systematically liquidated most holdings after announcing the corporate move. The price reduction on his final Chicago asset underscores the disparity in valuations between aging blue-state urban centers and the Florida markets where Griffin has concentrated his recent real estate acquisitions.
Griffin has articulated a clear strategic preference for Florida's business environment. Speaking at an Economic Club of Miami event several months after the 2022 relocation announcement, he stated: "There's something very special about the government in Florida and their focus on delivering traditional values for the community." In October 2025, Griffin disclosed at a Citadel Securities conference that the firm's planned office tower in Miami's Brickell neighborhood will likely cost approximately $2 billion, signaling substantial capital commitment to the Florida market. His South Florida real estate portfolio now spans high-profile properties across Palm Beach, Miami Beach, and Miami proper.
The Chicago penthouse sale represents a symbolic and financial culmination of a high-profile corporate migration trend, with Griffin repositioning both Citadel's operational footprint and personal wealth concentration toward Florida-domiciled assets during a period of significant interstate business relocation.
