With a net worth of $222 billion, Mark Zuckerberg is one of the richest people in the world and the owner of a massive real-estate portfolio that spans the entire U.S.
His latest purchase from August is a 440-acre estate and accompanying 196-year-old castle in County Waterford, Ireland, a purchase that reportedly set him back 51.17 million euros, or about $57.1 million.
Yet, his priciest purchases dates back to earlier this year, when the Meta CEO and his wife, Dr. Priscilla Chan, reportedly purchased a luxury mansion on Indian Creek Island in Florida near the in-progress home of Amazon founder Jeff Bezos.
The 300-acre, man-made Indian Creek Island is near Miami and Miami Beach and contains a mere 41 lots with approximately 84 residents, the Wall Street Journal reported. Home prices on the island start at about $60 million, and records show the billionaire paid $170 million for his waterfront home with nine bedrooms and 11 full bathrooms, the Miami Herald reported. Miami-Dade County property records note the owner as a land trust.
Even an undeveloped property on the exclusive island can fetch big bucks: One vacant lot roughly the same size as Zuckerberg’s sold for a reported $105 million in 2025.
The property Zuckerberg reportedly purchased at 2 Indian Creek Island Road puts him in the most coveted area of the already exclusive island, said Mitchell Duchon, a Miami Beach–based real estate agent with the Corcoran Group who specializes in high-end waterfront properties. On the western side of the island, where Zuckerberg’s property is reportedly located, lots are about 80,000 square feet, compared with about 50,000 square feet on the east side, according to Duchon. On this side, where Amazon founder and fellow billionaire Jeff Bezos also owns two lots, residents have better access to the open water of Biscayne Bay and a more expansive view with great sunsets, he added.
“That side of the island is perceived to be the most appealing,” Duchon said.
Bezos has been buying up properties on Indian Creek Island since he announced in 2023 he was leaving Seattle for Florida. The Amazon founder first purchased a $68 million home that would end up being just a few doors down from Zuckerberg’s in 2023. Near the end of that year, he paid another $79 million for a neighboring property with the intention of combining the lots into a single compound—a trend Duchon said is increasingly common among wealthy buyers because of the scarcity of truly expansive waterfront properties in the area. Meanwhile, Bezos is reportedly living in a third Mediterranean-style property also on Indian Creek Island, on the east side, which he snapped up for $87 million in 2024. Last year, Bezos sold one of his Seattle homes overlooking Lake Washington for a record $63 million, the Puget Sound Business Journal reported.
Indian Creek Island operates as an independent municipality with its own government and private police who patrol by air, water, and sky. Access to the island is controlled by a single gated bridge, making safety and privacy a defining feature. Most of the island’s interior comprises an 18-hole golf course and the Indian Creek Country Club, with a limited number of members owing, in part, to a difficult admissions process and a $500,000 initiation fee.
Zuckerberg is one of the latest billionaires to pick up a Florida property, especially in light of a proposed ballot initiative to be voted on in California next week that would impose a one-time 5% “billionaires tax” for any individual worth at least $1 billion dollars retroactive to Jan. 1, 2026. (To be sure, Zuckerberg still very much calls California home, having invested $50 million through Meta for a Sacramento downtown revitalization and AI-focused project earlier this year.) Google cofounder Larry Page also snagged a $71.9 million home in Miami’s Coconut Grove neighborhood in January that he plans to combine with another property to form a total $173 million waterfront compound.
Indian Creek Island, in particular, is home to a number of high-profile names, who, besides Bezos, include the financier Carl Icahn and former NFL quarterback Tom Brady.
Zuckerberg’s reported newest property is just the latest addition to the tech CEO’s growing portfolio of luxury homes across the U.S.
Palo Alto compound
Zuckerberg’s home base remains Palo Alto, where, according to the New York Times, he owns 11 properties in the Crescent Park neighborhood. Over more than a decade, Zuckerberg has poured $110 million into buying adjacent properties, in some cases drawing complaints from his neighbors.
Hawaiian estate
On the island of Kauai, about 100 miles northwest of Honolulu, Zuckerberg owns a $300 million property commonly known as Koʻolau Ranch, spanning roughly 1,400 acres. He quietly added about 1,000 additional acres to the compound last year, Architectural Digest reported, bringing his total Kauai holdings to more than 2,300 acres.
The ranch is one of Zuckerberg’s most secretive properties. Almost anyone who passes the compound security, including builders and other workers, must sign nondisclosure agreements, Wired reported. The ranch reportedly includes a 5,000-square-foot underground shelter with its own energy source.
Lake Tahoe retreat
Zuckerberg created his own mountain compound in the Lake Tahoe area through the purchase of two adjacent estates in Tahoe City on the lake’s West Shore. Lake Tahoe, in the Sierra Nevada mountains between Nevada and California, has emerged as a popular destination for billionaires seeking a retreat, with both Google cofounder Sergey Brin as well as 2020 presidential candidate Tom Steyer owning homes there.
Zuckerberg bought the properties—known as Carousel Estate and Brushwood Estate—for a total of $59 million, or $22 million and $37 million, respectively, according to multiple reports. The Brushwood Estate dates back to the early 1900s and has only had two other owners, according to SFGate. The property has six bedrooms, five full baths, and a 2,293-square-foot guesthouse.
Washington, D.C., mansion
As Meta and Zuckerberg have engaged more with policymakers in Washington, D.C. during the Trump administration, the tech CEO reportedly picked up a $23 million mansion in Washington D.C.’s exclusive Woodland-Normanstone neighborhood, Politico reported. The 15,000-square-foot mansion features brick and limestone walls and glass enclosed “walkways.”
