Ken Griffin closed on a penthouse in New York City for $238M on Wednesday, shattering previous records for the highest price ever paid for a home in the United States.

The Citadel hedge fund founder has closed on a penthouse unit at 220 Central Park South after signing a contract there in 2015, the Wall Street Journal reports.

The unit in the Vornado-developed, Robert A.M Stern-designed building was asking $250M. It will be delivered as a “white box,” unfurnished and undecorated, and spans 24K SF.

The Citadel is expanding in the city, and Griffin will need somewhere to stay when he is in New York, a company spokesperson told the WSJ. Citadel is expanding at L&L Holding Co.’s 425 Park Ave. — bringing its presence in the building to 332K SF, reportedly paying, for its part, a record-breaking office rent.

Griffin has been on a global pricey-property-purchasing binge in recent months, buying a home in London for $122M, the most expensive sold in the U.K. in more than a decade. He also spent a record-breaking $58.5M on a Chicago condominium in November.
