Ken Griffin’s Chicago Penthouse Returns to Market

Ken Griffin hasn’t quite severed his final tie to Chicago.

The billionaire Citadel founder’s 67th-floor penthouse at the Park Tower returned to the market after a deal to sell the condo apparently fell apart. The luxury condo is now listed for $12.3 million, below the $12.5 million price tag it carried late last year.

The six-bedroom, seven-bathroom Streeterville condo spans 9,250 square feet. The unit at 800 North Michigan Avenue first went on the market in 2022 asking $15.8 million. The asking price was repeatedly dropped over the years as the sluggish downtown market made it difficult for luxury condos to land buyers.

In December, when the listing asked $12.5 million, Griffin went under contract with an undisclosed buyer to purchase the penthouse. The potential buyer’s identity was not public, but the relisting indicates the deal didn’t close.

Susan Miner of Premier Relocation, the property’s listing agent, did not immediately respond to a request for comment. A spokesperson for Citadel didn’t immediately comment.

Griffin moved Citadel’s headquarters to Miami in 2022, pointing to crime in Chicago as a primary driver for the relocation. Since then, he engaged in a high-profile, aggressive selloff of his downtown Chicago luxury portfolio.

Griffin sold off his other high-altitute Chicago properties after relocating to Miami, and the Park Tower penthouse is his last property in the Windy City. The sales came with massive losses amid a general downturn in downtown Chicago’s market.

Griffin paid $58.8 million in 2017 for four unfinished floors at the top of the exclusive No. 9 Walton building. He sold those units over the last two years for a combined $35 million, taking a more than $23 million loss. Two of those units were sold to Illinois Gov. J.B. Pritzker and his wife MK for $19 million in 2024.

Griffin’s losses extended down a floor at the Park Tower, as well. He paid $15 million in 2012 for the 66th-floor unit directly beneath his current penthouse listing. He sold that condo to filmmaker George Lucas and his wife, Ariel Investments co-CEO Mellody Hobson, for $11.2 million in 2023.

Griffin also dumped a 37th-floor, full-floor unit at the Waldorf Astoria for $10.2 million in October 2022. Griffin originally paid $13.3 million for the condo in 2014.

If the Park Tower penthouse sells near its asking price, it would mark the most expensive single downtown condo deal in at least the last three years. The downtown market continues to battle headwinds, though notable trades still close, including the $7.5 million sale of former Fruit of the Loom CEO Bill Farley’s large penthouse at 209 East Lakeshore Drive in November, and Siri co-founder Dag Kitlaus’s purchase of a St. Regis Chicago unit for $9.3 million in October.
