When it comes to residential real estate, no one does it quite like Ken Griffin. The investment mogul appears to be keenly aware that kingdoms are built, not bought; his M.O. certainly bears out the suspicion, and delivers the kind of trophies money can’t buy. At least not outright.

Between August and December of 2020, Griffin spent heavily on Miami’s Star Island, the area’s ne plus ultra planned community: an 86-acre private island containing around 30 estates. Griffin dropped a total of $100 million to begin putting together a compound on the desirable Biscayne Bay destination, snapping up three properties in closings that registered at $25 million, $32.5 million and $35 million.

It turns out that Griffin closed on yet another Star Island property last month. This time he set a Miami-Dade County record, closing on a 1993-built mansion for $75 million. The Mediterranean-style house features eight bedrooms and fifteen full or partial baths across its 16,619 sq. ft. of interior living area. More importantly, it adds 1.8 acres to Griffin’s holdings on the western side of the island, and comes with 100 feet of water frontage.

The Star Island compound is shaping up to be a jewel in Griffin’s portfolio, but it’s not the half of it. In fact, not even the third of it. A few miles north, in Palm Beach, grander ambitions are already realized: In 2019, the hedge fund manager dropped $100 million on a 19,000-sq. ft. estate in the area, reportedly bringing his total expenditure on that compound to over $350 million. The estate measures in at 20 acres.

In 2018, Griffin set another record when he spent $238 million for a mansion in the sky in the Robert A. M. Stern-designed 220 Central Park South in Manhattan. Financier Dan Och recently sold his penthouse in the building for $190 million. A few miles east, and still on Griffin’s favorite coast, the Citadel founder owns a Hamptons home he purchased from Calvin Klein for around $85 million.

Griffin’s net worth is north of $25 billion, according to Forbes.
