Kenneth Griffin, manager of the Chicago-based hedge fund Citadel, is likely owner of the single most expensive apartments in New York, Chicago, and Miami, reported the New York Times’ Robert Frank.

The hedge fund billionaire bought nearly $US300 million worth of real estate in Chicago, New York and Miami, and has broken real estate records in each of the three cities over the past four months.

That includes two floors of Chicago’s Waldorf Astoria for a little under $US30 million, three floors at New York’s “billionaire’s bunker” at 220 Central Park South for about $US200 million, and Faena House’s penthouse in Miami, for $US60 million — $US10 million above asking price.

Though Griffin, who already owns properties in Aspen, Colo. and Hawaii, could be buying the properties as an investment. According to the Times, Griffin has no plans to live in the billionaire’s bunker, but plans to use it to house staff or guests, said people familiar with the deal.

Frank cited unidentified people familiar with the transactions, and Griffin declined to comment to the New York Times. The paper noted the purchases coincide with his messy and expensive divorce from wife of 11 years, Anne Dias Griffin.

The divorce trial is set for Monday. Dias Griffin is reportedly asking for $US1 million a month for child support of their two children.

Griffin earns about $US68.5 million a month after taxes, according to court filings for the divorce.
