Mark Zuckerberg and his wife, Dr. Priscilla Chan, have reportedly bought a luxury mansion on Indian Creek Island, often referred to as the “Billionaires’ Bunker” in Florida for $170 million, making it his most expensive property purchase this year, Fortune reports. While the Meta CEO’s latest acquisition was a 440-acre estate with a 196-year-old castle in Ireland for about $57.1 million, his costliest purchase this year reportedly came earlier, when he and his wife, Priscilla Chan, bought a waterfront mansion on Indian Creek Island near properties owned by Jeff Bezos. According to reports cited by Fortune, Zuckerberg paid around $170 million for the residence.
Inside Florida’s ‘Billionaires’ Bunker’
Located near Miami and Miami Beach, Indian Creek Island is a roughly 300-acre man-made island that contains only 41 residential lots and a small population. The island has earned the nickname “Billionaires’ Bunker” because of its concentration of ultra-wealthy residents, including Jeff Bezos, financier Carl Icahn and former NFL star Tom Brady. The property reportedly purchased by Zuckerberg at 2 Indian Creek Island Road is situated on the island’s western side, which real-estate experts consider the most desirable section. Larger waterfront lots, direct access to Biscayne Bay and expansive sunset views have made the western side especially attractive to billionaire buyers. According to the report, home prices on the island start at roughly $60 million, while even undeveloped waterfront parcels can sell for more than $100 million.
Privacy and security drive demand
A key attraction of Indian Creek Island is its privacy and security infrastructure. The island functions as an independent municipality with its own government and police force. Access is controlled through a single gated bridge, while security patrols operate on land and water. Much of the island’s interior is occupied by the exclusive Indian Creek Country Club and its 18-hole golf course. Membership is highly selective and reportedly requires a substantial initiation fee, adding another layer of exclusivity to the community.
Joining billionaire neighbour Jeff Bezos
Zuckerberg’s reported purchase places him close to fellow tech billionaire Jeff Bezos, who has steadily expanded his own footprint on the island since relocating to Florida in 2023.Bezos initially bought a $68 million mansion on the island before acquiring an adjacent property for $79 million. He is also reported to own another Mediterranean-style home on the island purchased for $87 million. The trend of combining adjacent waterfront properties into larger compounds has become increasingly common among ultra-wealthy buyers seeking greater privacy and larger estates.
A property portfolio spanning the US
The Florida mansion is only the latest addition to Zuckerberg’s extensive real-estate holdings. His home base remains in Palo Alto, California, where he reportedly owns multiple properties in the Crescent Park neighbourhood after spending more than $110 million acquiring adjacent homes over the years. In Hawaii, Zuckerberg owns the sprawling Koʻolau Ranch compound on the island of Kauai. The estate reportedly spans more than 2,300 acres and includes extensive security measures, with reports suggesting the property features an underground shelter and private energy infrastructure.The billionaire also owns a Lake Tahoe retreat created by combining two neighbouring estates purchased for a reported $59 million. More recently, he reportedly acquired a $23 million mansion in Washington, D.C.’s exclusive Woodland-Normanstone neighbourhood as Meta increased its engagement with policymakers in the US capital.
Timing amid California’s billionaire tax
The purchase comes as California voters prepare to vote next week on a proposed one-time 5 percent tax on billionaires, retroactive to January 1, 2026. Fortune notes that Zuckerberg still very much calls California home, pointing to his $50 million investment through Meta in a Sacramento downtown and AI project earlier this year. Google co-founder Larry Page bought a $71.9 million house in Miami’s Coconut Grove in January, which he plans to combine with another property into a $173 million waterfront compound.
