Facebook founder Mark Zuckerberg has reportedly found himself a new base in the Sunshine State in the form of an extravagant $170 million megamansion on Miami’s famed “Billionaire Bunker” island—just three doors down from a staggering compound owned by fellow tech tycoon Jeff Bezos.
According to the Wall Street Journal, the billionaire mogul is the proud new owner of a nine-bedroom, 11.5-bathroom property that was originally put on the market for the even higher price of $200 million in November 2025.
Zuckerberg’s reported purchase of the property, which closed on March 2, according to records, marks the most expensive residential real estate transaction ever completed in Miami-Dade County—and it is also one of the priciest homes ever sold in the U.S.
However, it is still a ways off from the official national record, which is currently held by billionaire Ken Griffin, who claimed the title when he snapped up a New York City penthouse for $238 million in 2019. The most expensive home ever sold in Florida—a $225 million waterfront compound in Naples—changed hands in April 2025.
It will be some time before the billionaire and his wife, Priscilla Chan, can move into the home, however, with construction on the opulent abode still ongoing. Renderings shared with the listing have revealed an extraordinary glimpse at the luxury they will enjoy when their new dwelling is completed.
When it was originally listed at the end of last year, the home was described as an “architectural masterpiece” that “defines the pinnacle of luxury waterfront living.”
The home was commissioned by plastic surgeon Aaron Rollins and his real estate agent wife, Marine Rollins, who purchased the 1.84-acre waterfront lot on Miami’s famed Indian Creek Island for $30 million in 2020, according to records.
They then teamed up with Canadian architect and designer Ferris Rafauli, who conceived everything from the structural layout to the interiors and the landscaping, according to information shared with Realtor.com®.
“Ferris designed all the architecture, all the interior design, and all the landscaping. He led the complete creative vision, designing the estate in its entirety from initial concept through to final execution,” an insider revealed.
While the property is still being built, the original designs for the home revealed that it had been designed with every luxury amenity imaginable. They include a waterfront swimming pool, a private dock, a gym, a hair salon and massage room, an aquarium, and a library—complete with its own secret passageway.
“From the limestone façade and grand architectural proportions to the meticulously curated interiors, every detail showcases modern artistry and exceptional craftsmanship,” the listing stated.
“This classically inspired residence offers endless views, indoor-outdoor living, and a sense of privacy and sophistication.”
It marks the first major Florida property purchase made by Zuckerberg, who has been based primarily in California for many years now. He began amassing a collection of properties in Palo Alto back in 2011, which now make up an extraordinary compound worth around $112 million.
The Facebook founder—who is originally from New York—has long since expanded his property portfolio beyond the borders of the Golden State, snapping up homes in Washington, DC; Hawaii; and Lake Tahoe.
It’s unclear whether the businessman has any plans to move his primary residence or his personal office to Florida in light of his new home purchase.
Either way, Zuckerberg’s new dwelling will immediately grant him entry into one of the most elite and high-profile communities in the U.S., which already counts the likes of Bezos and his wife, Lauren Sanchez Bezos, as well as Tom Brady, Ivanka Trump, and Jared Kushner among its residents.
Zuckerberg has yet to comment on the purchase of the home—nor has he publicly expressed any desire to move his residency from California to Florida.
However, news of the record-breaking buy comes amid something of a wealth exodus from California, which is currently in the process of voting on a proposal to implement a one-time tax of 5% on residents who have a net worth of more than $1 billion.
According to Forbes, California is currently home to 246 billionaire residents who would be forced to hand over anywhere from $50 million to $13 billion apiece if the tax proposal is passed.
In Zuckerberg’s case, the tax would likely cost him around $11.5 billion, given his current net worth, which stands at $229 billion at the time of writing, according to the Bloomberg Billionaires Index.
The fact that the wealth tax has yet to be signed into law has done little to deter the Golden State’s wealthiest residents from hauling their personal fortunes out of California, with everyone from Oracle founder Larry Ellison to former Google head Sergey Brin moving their business dealings to states such as Florida and Nevada.
Brin reportedly transferred five LLCs connected to the billionaire out of California at the end of 2025, while venture capitalists Peter Thiel and David Sacks both announced the opening of new satellite offices in Florida and Texas, respectively, laying a paper trail that might thwart future California tax collectors.
Interestingly, while other wealthy California residents have been open in their objections to the wealth tax, Zuckerberg has remained somewhat mum about the proposal, although he has continued to invest ample funds into the continued growth of the state’s technology epicenters.
In January, he pledged $50 million to Sacramento State University to help it build new STEM labs and an AI center, saying in a statement provided to Fortune that he hoped the money would help to “support the next generation of leaders and inventors.”
California Gov. Gavin Newsom, who is vehemently opposed to the billionaire tax, praised the gift, saying that it will “open doors for students to success and for our communities to prosper.”
Newsom has previously vowed to put a stop to the billionaire tax, telling the New York Times in January that he was working diligently behind the scenes to ensure that the measure is not implemented.
“This will be defeated—there’s no question in my mind,” he said. “I’ll do what I have to do to protect the state.”
However, those in support of the ballot measure have accused Newsom of prioritizing the needs of the state’s richest 1%, rather than the majority of its residents, whom the tax’s most devoted backers insist would be the ultimate beneficiaries of the levy.
