A hedge fund billionaire has purchased a Central Park penthouse apartment for $238 million — the most anyone has ever paid for a home in the United States.

The sale, which closed Wednesday, was confirmed by a spokesman for the buyer, Kenneth Griffin.

The unit, a nearly 24,000-square-foot combination of two apartments, is at the top of 220 Central Park South, an under-construction tower developed by Vornado Trust Realty and designed by the firm of Robert A.M. Stern.

The sale dwarfs the previous record-holder in New York City, a $100.5 million duplex sold in 2014 at One57, a nearby high-rise that helped rechristen a sleepy strip of Midtown across 57th Street as “billionaires’ row.”

The previous United States record-holder was a $137 million East Hampton home that sold in 2014.

The Wall Street Journal first reported the closing.
