Summary
Ken Griffin, the billionaire founder of Citadel hedge fund with an estimated net worth of $34.4 billion according to Forbes, is undertaking a substantial residential development project in Palm Beach centered on constructing an oceanfront mansion for his mother, Catherine Gratz Griffin. The property is located at 60 Blossom Way on the northern section of Griffin's expansive 27-acre ocean-to-lake estate, one of the largest contiguous residential holdings in Palm Beach.
The residential compound will comprise three structures: the primary oceanfront mansion, a separate guesthouse, and a utility building, totaling approximately 44,000 square feet of combined floor space. The structures will extend approximately 350 feet along the beachfront. The design received architectural approval from the Palm Beach Architectural Commission in July 2022, with modifications to the utility building approved exactly one year later in July 2023. The property will serve as a residence for Griffin's mother while providing accommodations for family members and visitors.
Griffin's Palm Beach real estate portfolio represents a long-term acquisition strategy initiated in 2012. Over the course of more than a decade, he has assembled his current estate by purchasing 10 separate properties, investing more than $500 million in cumulative acquisitions. His total contiguous beachfront spans approximately 1,400 feet—roughly a quarter mile of oceanfront property in one of the world's most sought-after residential markets.
Beyond this Palm Beach project, Griffin has aggressively expanded his Florida footprint as part of his broader corporate relocation strategy. In 2023, he relocated Citadel headquarters from Chicago to downtown Miami and acquired a $107 million waterfront residence in nearby Coconut Grove for personal family use. He has also invested in commercial real estate on Palm Beach's premier Worth Avenue, recently purchasing two side-by-side commercial buildings including a retail-and-office asset acquired for a recorded $83 million.
Despite his substantial investments in Miami and Coconut Grove properties, Griffin has publicly indicated plans to construct an additional residence for himself on his Palm Beach estate, suggesting further development of the property beyond the current oceanfront mansion project for his mother.
