Palantir CEO Alex Karp moved to his ‘Billionaire Bunker’ months before moving headquarters to Miami
Palantir CEO Alex Karp reportedly got his own “Billionaire Bunker” in Miami months before the company relocated its headquarters there. A report claims that his move came long before Facebook founder Mark Zuckerberg and other technology executives began purchasing property in the city. According to public records seen by Bloomberg, Karp bought a mansion in Miami Beach in June 2025, around seven months before Palantir announced plans to move its headquarters to Miami. Palantir, one of the biggest Silicon Valley-born companies that has become the face of defence software in the US for its work with the government on the battlefield and in immigration enforcement, announced in a post on X in February 2025 that it was moving its headquarters from Denver to Miami. Though it hasn’t provided further information on its plans in Miami, the company’s principal executive offices are now listed at a coworking space in Aventura, about 17 miles north of downtown.
What we know about Alex Karp ’s Miami property
The property, located on a man-made island, was purchased for $46 million through an entity called Hibiscus East LLC, which listed New Hampshire lawyer Patrick Collins as its representative, the Bloomberg report claims. Collins has previously worked with Karp on other real estate deals, and the Palantir executive also owns property in New Hampshire.Palantir declined to comment on the purchase, while Collins did not immediately respond to requests for comment. Real estate agents Zalmy Shapiro and Joel Lusky, who represented the buyer, also declined to comment. Dina Goldentayer of Douglas Elliman, who represented the sellers, did not comment either.The Bloomberg Billionaires Index estimates Karp’s net worth at $16 billion, and he is among several wealthy technology executives who are acquiring property in Miami. The area has drawn interest partly due to tax proposals targeting high-income individuals in states such as California.
What are these ‘Billionaire Bunkers’ and why tech leaders are moving in there
Silicon Valley’s home state, California, has proposed a 5% tax on billionaire wealth. The proposed 2026 California Billionaire Tax Act seeks to impose a one-time 5% tax on the global net worth of residents with more than $1 billion in assets to fund healthcare and education. While the initiative has gained early support through signature collection, it faces opposition from critics who warn it could drive wealthy residents out of the state and lead to legal challenges. California Governor Gavin Newsom has also opposed the measure and expects it to be defeated.This billionaire wealth tax has reportedly prompted Mark Zuckerberg and other technology billionaires to move away from California. The Meta CEO recently purchased a $170 million property in Indian Creek, a gated island community sometimes referred to as the “billionaire bunker.”Meanwhile, the founders of Google, Sergey Brin and Larry Page, have also bought property in Miami this year. Earlier this week, Starbucks’ former CEO, Howard Schultz, said he had also moved to the city.
