The multi-billionaire hedge fund magnate Ken Griffin, who founded the Chicago-based Citadel Securities, has expanded his Star Island assemblage with the acquisition of 10 Star Island for $25 million. In August 2020 an entity tied to Ken Griffin acquired the adjacent double lot with Miami Vice views of Downtown Miami at 11 and 12 Star Island Drive in an off-market deal for roughly $37 million. Soon after, Griffin would purchase 13 Star Island for $32.5 million after the property was previously linked to Alex Rodriguez and Jennifer Lopez. The acquisition of 10 Star Island brings his assemblage to roughly $95 million.

Ken Griffin’s net-worth is estimated to be about $15 billion and he has been one of the largest luxury property buyers in the world over the past several years. In 2015 Griffin purchased two penthouses in Faena House on Miami Beach for a record at the time $60 million. He recently sold the larger of the two penthouses for $35 million and is now reportedly under contract to sell his second penthouse, which is currently listed for $12.5 million. In 2019 Griffin purchased a $240 million unit at 220 Central Park South in Manhattan, NYC, in a deal that broke the record for the most expensive residential transaction ever recorded in the U.S. In Palm Beach Griffin has assembled $350 million of land at Blossom Way and South Ocean Blvd. where he began buying in 2012.
