Ken Griffin is one big step closer to cutting his final Chicago condo loose. The Citadel founder, who has been shifting both his family and his firm to Florida, is reportedly under contract to sell one of his last remaining trophy homes in the city: a high-floor condominium at Park Tower, 800 N. Michigan Avenue.
The Park Tower unit, originally listed at $12.5 million, went under contract only after a roughly $3.25 million price cut from its July asking figure, according to Bloomberg. A spokesperson confirmed to the outlet that the home is under contract, although the final closing price has not been disclosed.
The pending sale is the latest chapter in a yearslong pullback from Chicago real estate for Griffin. He has been unloading downtown holdings since announcing in 2022 that he would move Citadel's headquarters, and his own home base, to Miami, a broader trend detailed by The Real Deal. That outlet has tracked earlier sales, including the disposal of two full floors at 9 West Walton, that steadily trimmed his exposure to the city's ultra-luxury condo market.
A Compass listing for units at 800 North Michigan Avenue describes Park Tower as a 67-story building with hotel-style amenities managed by Hyatt, and MLS notes for some listings were last updated on July 1, 2025. Those details help explain why condos in the building are treated like market barometers, with buyers and sellers watching closely as high-end price expectations get adjusted.
What the Sale Signals for Chicago Luxury
The hefty price cut on Griffin's Park Tower condo, followed by its under-contract status, underscores how even the most rarefied homes are not immune to a cooler market at the top. The Real Deal has reported that some of Griffin's earlier Chicago condo sales closed well below what he originally paid, a pattern that has added pressure on list prices across the upper tier.
For now, Griffin and his representatives are not saying more than what was confirmed to Bloomberg, and the agreed-upon number remains under wraps. If the deal closes, the final sale price will offer one more closely watched data point on what Chicago's priciest downtown condos can actually fetch in the current market.
