The Most Expensive Apartment Ever Sold

Ask almost anyone what the most expensive apartment ever sold is, and you'll hear the same number: $238 million, for Ken Griffin's glass penthouse above New York's Central Park. For seven years that was the record everyone quoted — and it was wrong. In April 2026, it emerged that the real record had been quietly, secretly broken by more than double: a five-floor apartment in Monaco that sold for $554 million. This is the full story of the most expensive apartment ever sold, from Billionaires' Row to a brand-new district floating on the Mediterranean Sea. A note on the numbers: luxury real estate is a world of estimates and private deals. Every figure here is drawn from reporting by Bloomberg, The Real Deal, CNN and others, and softened where a price was never officially confirmed.
