California's billionaires are moving to Miami. We mapped out where they are buying.

Called the Billionaire Bunker, this private island in Biscayne Bay has long been home to the ultrarich and is known for its intense security, 25,000-square-foot mansions, and exclusive golf club.

Carl Icahn and Tom Brady have homes there, as do Jared Kushner and Ivanka Trump. Amazon founder Bezos, who has purchased three properties on the island for $237 million, made it his home base in 2023 — a year after a 7% capital gains tax went into effect in his home state of Washington. Since his arrival, prices have increased; a 1.84-acre lot neighboring his property sold for $105 million last year.

Zuckerberg may be next. He is circling a waterfront property on the island that is listed for $200 million, The Wall Street Journal reported. That would set a record for both the ritzy island and the county as a whole.

Allison Island is a gated private island in northern Miami Beach. While less exclusive than the better-known Indian Creek, it boasts 24/7 security and ample waterfront — which, agents said, translates to high prices.

There are several eight-figure properties for sale on the island, and Page's Google cofounder, Brin, is eyeing a $50 million home there, The Wall Street Journal reported. At the end of last year, the pair began cutting their ties to California, where Google is headquartered.

Fisher Island is home to resident-only restaurants and drama surrounding members-only clubs. Accessible only by boat or helicopter, the island's main draw is the fact that residents can't be disturbed by outsiders.

"Fisher Island is like a boutique, it's like a unique place — you cannot find land over there," Yizhak Toledano, CEO of Sky Development, told Business Insider.

The community is 216 acres — compared to the nearly 300-acre Indian Creek — and has about 800 residents who mostly live in the many condos on the island, which can go for as much as $40 million.

With coveted waterfront properties and a history of famous residents, Coconut Grove has gone from bohemian to luxury. Over the last five years, though, sales have reached new heights.

It's where Ken Griffin spent a record-breaking $106 million on an estate in 2022, and where Google cofounder Page has set up shop. He spent more than $180 million on three properties in the neighborhood, including a $101.5 million compound with a pool, grottos, a guest house, and a gym, and $71.9 million property with seven bedrooms.

Home to the University of Miami, Coral Gables is a neighborhood that offers an urban lifestyle and the waterfront that wealthy residents often seek.

The tony neighborhood is highlighted by the exclusive Gables Estates, a gated community — named the most expensive neighborhood in the country — home to celebrities like Pharrell Williams, who bought a $30 million home, and The Weeknd, who purchased a $50 million property in 2025.

Last month, billionaire businessman Jorge Mas bought two properties there, including a mansion that sold for a record-breaking $75 million, The Real Deal reported.
