The duplex penthouse under contract at Faena House in Miami Beach could shatter Miami-Dade County’s pricing record by selling for a whopping $60 million.

At $60 million, the five-bedroom condo would end up going for $10 million above the listed asking price. The buyer of the 8,273-square-foot penthouse is still unknown. Reported early buyers at the mid-Beach building include Apollo Global Management co-founder Leon Black, Goldman Sachs Group CEO Lloyd Blankfein and art dealer Larry Gagosian.

The five-bedroom penthouse includes about 10,000 square feet of exterior space and a 70-foot-long rooftop pool with ocean views. Faena House, the condo component of Alan Faena’s mixed-use Faena Miami Beach, has been sold out since April.
