illionaire Ken Griffin's Chicago real estate portfolio is taking a hit as he offloads luxury properties after relocating to Florida. Griffin, who moved his family and Citadel headquarters to Miami, recently sold his unfinished penthouse at 9 West Walton for $11 million, half of what he paid in 2017.

    The 38th-floor unit was initially listed at $21 million, a loss of around $10 million if the deal closes at or near the current price. Griffin had previously made headlines with his four-floor, $58.5 million investment at the luxury tower in Chicago's Gold Coast neighborhood.

    Griffin has struggled to sell other units in the building, with the luxury market in Chicago moving slowly compared to hot markets like New York and Miami. He recently listed his 37th-floor unit for $9 million, a loss from his original $12.7 million purchase price.

    In total, Griffin has lost around $17 million on four properties in Chicago, including two other units at the Waldorf Astoria Chicago and Park Tower. However, things are looking up in Florida, where he has invested around $300 million in properties and is developing the most expensive home in the United States, worth an estimated $1 billion.

    Griffin's fortune remains intact, valued at a staggering $43 billion. He continues to aggressively invest in Miami, dropping around $300 million on several properties, including lavish estates on Star Island and Coconut Grove.
