Meta CEO Mark Zuckerberg and his wife, Priscilla Chan, have acquired an under-construction estate on Miami's exclusive Indian Creek island for $170 million. The transaction, which closed on Monday, sets a new real estate record for Miami-Dade County.
The purchase places the property among the most expensive residential sales ever recorded in the United States, highlighting the continued strength of the ultra-luxury market in South Florida. The deal was confirmed through local multiple listings service data.
Key Takeaways
- Mark Zuckerberg and Priscilla Chan purchased an estate on Indian Creek island for $170 million.
- The sale establishes a new real estate record for Miami-Dade County.
- The property was still under construction at the time of the sale.
- Indian Creek is a highly exclusive, private island known as the "Billionaire Bunker."
A New Benchmark for Miami Real Estate
The $170 million sale price officially makes this the most expensive home ever sold in Miami-Dade County. This transaction surpasses previous local records and signals a new peak for the region's high-end property market.
While a significant figure, it falls short of the current Florida state record, which was set last year by the sale of a waterfront compound in Naples for $225 million. The national record for a residential purchase remains Ken Griffin's acquisition of a New York City penthouse for approximately $238 million in 2019.
Luxury Real Estate Records
- New Miami-Dade Record: $170 Million (Zuckerberg/Chan)
- Florida State Record: $225 Million (Naples, 2025)
- U.S. National Record: ~$238 Million (Ken Griffin, NYC, 2019)
The fact that the property is still under construction adds another layer to the sale. Buyers in this price bracket often prefer to customize a new build to their exact specifications rather than retrofitting an existing structure, a trend that is becoming more common in exclusive enclaves.
Inside the 'Billionaire Bunker'
The location of the purchase, Indian Creek island, is as notable as the price tag. The 300-acre barrier island is often referred to as the "Billionaire Bunker" due to its extreme exclusivity, privacy, and roster of high-profile residents.
The island is a self-contained municipality, Indian Creek Village, with its own mayor and a private police force that patrols the island's single road and surrounding waters 24/7. Access is restricted to a single, heavily guarded bridge, ensuring unparalleled security for its inhabitants.
What is Indian Creek Island?
Indian Creek is a man-made barrier island in Biscayne Bay with just over 40 waterfront residential lots. It is known for its extreme privacy and security, featuring a private 18-hole golf course in the center and a dedicated police force for its small number of residents.
The island's community includes a small, elite group of individuals from the worlds of finance, sports, and entertainment. The addition of Zuckerberg and Chan further cements its reputation as one of the wealthiest and most secure communities in the world.
The State of the Ultra-Luxury Market
This record-setting purchase underscores the resilience and continued growth of the ultra-luxury real estate sector, particularly in South Florida. The region has become a magnet for wealth, attracting high-net-worth individuals with its favorable tax laws, warm climate, and vibrant culture.
Real estate experts note that inventory at this level is extremely limited, which drives prices to historic highs when a premier property becomes available. A waterfront parcel on a secure, private island like Indian Creek represents the pinnacle of this scarcity.
The acquisition is a significant personal investment for the couple and a major indicator of market confidence. It demonstrates that despite broader economic fluctuations, demand for unique, trophy properties in prime locations remains exceptionally strong. The final details of the new mansion are not public, but properties on the island typically feature extensive waterfront access, private docks, and sprawling grounds that offer complete seclusion.
