Mark Zuckerberg and his wife Priscilla Chan have purchased an unfinished limestone mega-mansion on Indian Creek, an exclusive private island in Miami-Dade County known as the "Billionaire Bunker", for a record $170 million. The purchase marks the highest price ever paid for a home in Miami-Dade County, though it still trails the US record set by Ken Griffin's $238 million Manhattan buy in 2019 and the Florida record of $225 million for a waterfront property in Naples.

Why it matters

The record-breaking sale highlights the continued growth of Miami as a destination for the ultra-wealthy, with the city's exclusive enclaves like Indian Creek attracting high-profile buyers looking for luxury homes and privacy. The purchase also demonstrates Zuckerberg's vast personal wealth and willingness to invest heavily in real estate.

The details

Zuckerberg and Chan's new 14,000-square-foot limestone mansion is still under construction on the 300-acre Indian Creek island, which is home to just 42 residences and features 24/7 security and its own police force. The couple purchased the property directly from the developer.

  • The sale closed on March 4, 2026.
