From secluded estates to a former monastery, take a look at Palantir CEO Alex Karp's lavish properties

• Alex Karp has built an impressive portfolio of residential real estate properties.
• His portfolio includes two mansions next door to each other on Miami’s exclusive San Marino Island.
• Together, the two properties are worth nearly $75 million and could be the start of a Karp compound.

Karp may be building a compound in Miami.

According to its original listing, the property is “situated in a private mountain valley” in Capitol Creek Valley.

The property was originally listed for $150 million in 2024, but ultimately sold to Karp for $120 million, according to The Wall Street Journal, which cited a source familiar with the deal.

Ken Mirr of Mirr Ranch Group, the listing agent who represented the sale, declined to confirm whether Karp was the buyer. But he told the Journal that the deal set a record for Pitkin County.

The land for St. Benedict’s Monastery was purchased in 1956 by the Cistercian Order of the Strict Observance, a Roman Catholic religious order known as the Trappists, for an undisclosed amount. The monastery was built two years later.

For decades, the monks cared for the land, supporting themselves through farming and candy sales. But their numbers gradually dwindled, and by the time of the sale, reportedly only five monks remained.

Today, the compound still has a chapel, prayer areas, monks’ living quarters, a monastery building, and a retreat center.

Business Insider contacted Patrick Collins, the lawyer connected to Hibiscus East LLC; Ken Mirr, the listing agent for St. Benedict’s Monastery; and Dora Puig, the listing agent for Karp’s 29 East San Marino Drive property, but did not receive a response.
