Billionaire Rinat Akhmetov, Ukraine’s richest man, bought a vast, five-floor luxury apartment in Monaco’s most prestigious new development for an eye-popping €471 million ($554 million), making it one of the biggest single home transactions in history.

The 21-room waterfront property, acquired by the businessman’s holding company, is located in the principality’s Mareterra district. The new area, built on reclaimed land, was inaugurated by Prince Albert II in 2024 and has drawn ultra-rich investors from around the world.
