Hedge fund titan Ken Griffin is about to cut the last of his personal ties to Chicago.

Griffin, the CEO of Citadel, broke up with the Windy City in 2022 after three decades in residence. It was an acrimonious split. The businessman took his family and his headquarters to Miami, leaving Chicago — and several trophy homes — out in the cold.

Griffin’s final remaining and longest-held Chicago property, a six-bedroom duplex, went under contract on Tuesday, Crain’s Chicago Business reported. The penthouse condo had recently re-listed at a discount, asking $12.5 million.

Griffin was outspoken about the Midwestern city’s crime rates, high taxes and woke culture, which sent him — and his billions of dollars — fleeing for sunnier conditions.

Griffin has an estimated net worth of $50.5 billion, according to Forbes, making him the 33rd richest person in the world today.

Griffin listed a total of five Chicago penthouses in several prime Gold Cost towers in 2022, Crain’s reported.

This final sale along North Michigan Avenue takes up the entire 67th floor of the luxurious Park Tower. Griffin previously lost $3.8 million selling off another unit on the tower’s 66th floor, according to the outlet.

This under-contract home on the 67th floor spans 9,250 square feet, with 12-foot ceilings and a private elevator. Its three outdoor spaces include a custom Jacuzzi deck and a 400-square-foot rooftop terrace equipped with a custom kitchen, according to the listing.

The next owner will benefit from some intense security features, like facial recognition and a “lockdown mode.”

Griffin purchased the six-bedroom duplex in 2000 for $6.9 million, according to property records. It hit the market for $15.75 million amid Citadel’s 2022 departure, rotating on and off the market until reappearing for $12.5 million this week.

Listing agent Susan Miner of Premier Relocation could not be reached for comment.

The rest of Griffin’s portfolio included a 37th-floor home at the Waldorf Astoria and a four-penthouse spread on West Walton Street. The latter collectively cost Griffin $58.5 million in 2017, Crain’s reported, setting a then-record for the city.

Two of the four West Walton pads sold in 2024 to Illinois Governor JB Pritzker for a discounted $19 million. The last two, both unfinished, found a buyer this spring at a $8.79 million discount. Griffin’s losses on the West Walton spread totaled 40% of his 2017 investment, Crain’s reported.

Zia Ahmed, a spokesperson for Griffin, pointed to the city’s weakening housing market.

“The decline in Chicago’s high-end real estate market is yet another cost of years of failed leadership in Illinois,” Ahmed told The Post. “In contrast, the stunning appreciation of Ken’s Florida properties reflects the impact of good governance by state and local leaders.”  

As Griffin finishes icing out his investments in Chicago, his billion-dollar dealmaking in South Florida is certainly heating up.

Griffin — already the proud owner of the country’s most expensive residence at 220 Central Park South — is reportedly building the priciest home on the planet in Palm Beach.

A Florida native, Griffin has spent well over $1 billion on Sunshine State real estate. In 2022, Citadel spent a record-setting $363 million for a site along Miami’s Brickell Avenue for its forthcoming headquarters.

Griffin set a Miami-Dade record of his own when he purchased a 4-acre Coconut Grove estate in 2022 for $106.9 million. He continued the buying spree into 2023, shelling out approximately $169 million for a seven-property assemblage on the exclusive Star Island.

And the cherry on top — he recently secured planning approval for a more than 30,000-square-foot personal megayacht marina in Miami Beach.
