Yes, it appears so. I just did a search on Wikipedia, and here's what I saw on this article:
"The top two floors of One57 sold to Michael Dell for $100.47 million in 2015, setting a record for the most expensive apartment ever sold in New York. Another bi-level apartment in the building was bought by hedge fund manager Bill Ackman for $91.5 million. The top penthouse at 432 Park Avenue went to Saudi retail magnate Fawaz Al Hokair for $87.7 million, and hedge fund manager Kenneth C. Griffin is said to have bought three floors at 220 Central Park South for $238 million, breaking One57's record for the most expensive home sold in New York City and setting a new record for the most expensive home sold in the United States. Also at 220 CPS, several units were combined into a four-story mansion costing $250 million."
