Ken Griffin, founder of and CEO of Citadel, has inked the most expensive single residential real estate deal in U.S. history. The billionaire hedge fund manager has reportedly purchased several floors of a new condo tower in midtown Manhattan for $200 million. 
The 46 year old American trader has secured three floors of 220 Central Park South, a Robert Stern-designed building still under construction. The triplex, which will be located on midlevel floors of the 65-story building, includes a main residence as well as separate units for staff, household help and guests. Altogether, the various units will total more than 18,000 square feet.
Palm Beach property owner Ken Griffin already owns several of the highest-priced condos ever purchased in Chicago history. However with the latest property acquisition, the billionaire may be looking forward to a more longer and luxurious stay in New York.
