Palantir CEO Alex Karp nabs Aspen-area ranch for $120M

Alex Karp's purchase of St. Benedict's Monastery marks priciest residential sale in Pitkin County history

Palantir CEO Alex Karp bought Colorado's St. Benedict's Monastery, once home to Trappist monks, for a hefty $120 million. 

The Aspen-area ranch will become the latest in his growing list of real estate holdings. 

The property is located in Snowmass, Colorado, which is about 30 minutes from Aspen, and was originally asking $150 million when it went on the market last year, Ken Mirr of Mirr Ranch Group, one of the listing agents, told The Wall Street Journal.

The entire 3,700-acre property, including the monastery, was sold to Karp, marking the priciest residential sale to date in Colorado’s Pitkin County, Mirr told the Journal.  

For 70 years, it was under the ownership of Trappist monks, though only a few still live there, the Journal reported. While Mirr didn't disclose the buyer's identity, he noted that the buyer won't use the property as a home.

While it's a record-breaking sale, it's only a fraction of Karp's net worth. Karp is listed on Bloomberg's Billionaires index among the world's wealthiest individuals. As of late 2025, he was the 146th richest person in the world with a net worth sitting at just over $17 billion, according to the index.
