- Palantir CEO Alex Karp is tied to a $46 million waterfront mansion on Miami’s San Marino Island, purchased in June 2025.
- The buy came seven months before Palantir announced its headquarters move from Denver to Miami.
- The 9,700-square-foot home was bought through a Delaware LLC linked to Karp’s attorney and accountant in New Hampshire.
- Karp, worth an estimated $14 billion, also paid $120 million for a 3,700-acre Colorado monastery in December 2025.
- Palantir’s market cap sits around $360 billion, making it one of the most valuable defense-tech companies in the world.
A $46 Million Purchase, Seven Months Before the HQ Announcement
In June 2025, a Delaware-registered entity called Hibiscus East LLC purchased a newly built waterfront home at 55 East San Marino Drive for $46 million, according to property records first reported by The Real Deal. The LLC is connected to an attorney’s office and an accounting firm in New Hampshire — both of which appear on documents from previous real estate transactions linked to Karp.
The nearly 10,000-square-foot property sits on San Marino Island, one of the exclusive Venetian Islands in Biscayne Bay. The sellers were Tom and Patricia Kennedy, founders of a Miami Beach-based software firm. Listing agent Dina Goldentayer of Douglas Elliman originally asked $48.5 million. Seven months later, in February 2026, Palantir announced it was moving its headquarters from Denver to Miami — a move Karp had apparently been preparing for well in advance.
Protests, Politics, and a $360 Billion Empire
Palantir’s departure from Denver followed more than a year of escalating protests targeting its offices. Activists organized street theater, pickets, rallies, and vigils over the company’s contracts with ICE and its work with the Israeli military. Colorado’s 2024 AI bill, which imposed new compliance requirements around algorithmic discrimination, also weighed on the decision. Palantir cited the legislation in SEC filings, warning that compliance “may be difficult, onerous, and costly.”
Florida offers what Denver did not: no state income tax, a business-friendly governor, and fewer regulatory headaches. Karp, who reportedly owns 20 properties around the globe — most near ski resorts — is no stranger to high-end real estate. In December 2025, he paid $120 million for St. Benedict’s Monastery, a 3,700-acre former Trappist monks retreat near Aspen, the priciest residential sale in Colorado’s Pitkin County history. His primary residence remains a 500-acre estate in New Hampshire, bought for $825,000 in 2019. The Miami mansion is just the latest addition to a billionaire portfolio that keeps growing alongside Palantir’s stock, which trades around $153 at a market cap north of $360 billion.
