Summary
Billionaire hedge fund founder Ken Griffin has formally completed his geographic transition from Chicago to Miami with the sale of his final Chicago property—a $12.5 million penthouse at Park Tower, located at 800 North Michigan Avenue. The full-floor duplex condo, listed by Susan Miner at Premiere Relocation and confirmed under contract by Griffin's spokesperson to Bloomberg News, represents the end of a sweeping real estate divestment that commenced in 2022 when Griffin relocated his Citadel and Citadel Securities headquarters to South Florida.
The 9,250-square-foot property, built in 2000, exemplifies trophy asset characteristics typical of ultra-high-net-worth portfolios. Originally purchased in 2000 for $6.9 million, the penthouse was marketed as the "crown jewel" of Park Tower, featuring a six-bedroom, 6.5-bathroom layout with 12-foot ceilings and 360-degree panoramic views. The unit includes three private outdoor spaces—a custom jacuzzi deck, semi-enclosed balcony, and a 400-square-foot rooftop terrace with custom outdoor kitchen. Security amenities include facial recognition entry systems, lockdown capability, a secured private elevator foyer, and 24-hour building security, alongside privileges at the adjacent five-star Park Hyatt Hotel. Monthly homeowner association fees are $8,446.
While the final sale price of $12.5 million represented a reduction from the July 2025 listing price of $15.75 million, Griffin's sale still delivered a meaningful profit relative to his 2000 acquisition cost, demonstrating the appreciation trajectory of premier Chicago lakefront properties over two decades. This transaction concludes Griffin's Chicago real estate chapter as he consolidates his personal and professional footprint in South Florida.
Griffin's relocation strategy extends beyond headquarters operations. In 2022, he purchased a 4-acre Coconut Grove estate for $106.9 million, setting a Miami-Dade County record. His announced Miami office tower project, estimated at $2.5 billion, signals substantial capital commitment to South Florida and represents a structural realignment of Citadel's operational geography away from the Midwest toward a Florida-based headquarters model.
