Palantir CEO Alex Karp has set a new benchmark for luxury real estate in the Aspen area, paying a record $120 million forĀ a sprawling ranch outside Aspen, Colorado, according to a source with knowledge of the deal. The sale surpasses the previous record $108 million residential transaction in Pitkin County, making it the most expensive completed home sale in the region’s history.

The property, located in Snowmass about 30 minutes from Aspen, was formerly St. Benedict’s Monastery, a secluded complex owned for roughly 70 years by an order of Trappist monks. The ranch spans approximately 3,700 acres and was listed last year for $150 million. Ken Mirr of Mirr Ranch Group, one of the listing agents, confirmed to the Wall Street Journal that the deal now holds the county’s residential sales record, though he declined to identify the buyer. He said the new owner plans to use the property as a private residence. Public records identified the buyer as a Espen LLC, a company registered at the monastery’s address. However, the Wall Street Journal identified the person behind Espen as Palantir’s Alex Karp.

Modeled after a 12th-century Cistercian abbey, the monastery features arched windows, peaked cupolas, and a prominent steeple. The main monastery building dates to the 1950s and measures about 24,000 square feet, while a 6,000-square-foot retreat center was added in the 1990s using reclaimed timber and local stone. The property also includes several historic houses built around 1900, small cabins, a barn, offices, and equipment sheds. Much of the land remains undeveloped.

Bordered by National Forest, the ranch is threaded by Capitol Creek, Lime Creek, and Little Elk Creek, offering expansive views of Mt. Sopris and rare privacy so close to Aspen. Over the decades, the monks raised hens, sold eggs, and more recently leased portions of the land to a local cattle rancher. Only about five monks still reside on the property.

Karp, co-founder and CEO of Palantir Technologies, leads a data-analysis firm closely associated with U.S. military and intelligence agencies. Founded in 2003 alongside high-profile tech names such as Peter Thiel, Palantir has made Karp a billionaire many times over, with Bloomberg estimating his net worth at roughly $18 billion. His software firm sells some of the most powerful and dangerous technology in the world, ingesting huge quantities of data and spotting patterns, trends, and connections that would likely elude most people. Palantir has significantly expanded its work with the Trump administration, securing major government contracts, especially for developing AI tools for agencies like ICE to track migrants. Karp is also known to be an avid skier, a fitting profile for a buyer drawn to a vast, mountain-bound estate near Aspen. Author and journalist Michael Steinberger described Karp in his 2025 book ā€œThe Philosopher in the Valley,ā€ as an eccentric individual with a fanatic obsession with fitness. He owns around 20 homes around the world and is said to have a girlfriend in each place. He is guarded round the clock by super-fit Norwegian body guards reportedly recruited from the Norwegian special forces because they are the only security personnel fit and skilled enough at the sport to keep up with him on his extensive, midday cross-country skiing workouts or save him in a potential snowstorm. The monastery should provide the perfect compound to house his private Norwegian security detail.

Nine-figure home sales are a relatively new phenomenon in the Aspen and Snowmass markets. The previous record sale occurred last year, when Steve Wynn and Thomas Peterffy paid $108 million for a Red Mountain estate. Mirr noted that the monastery deal was not a typical Aspen transaction centered on a massive single mansion, but rather driven by the rarity of 3,700 largely untouched acres in such close proximity to the resort town.

The sale marks the end of the Trappist monk’s 70-year history in Aspen. According to Kaya Williams of Aspen Journalism, the final public mass at St. Benedict’s will be held on January 11, 2026. She also reports that Espen LLC granted an access easement for the monastery’s cemetery, to allow families of those buried in the cemetery access to graves on the ranch. No information is available about an official deconsecration of the church.

The sale comes amid continued upward pressure in Aspen-area luxury real estate. Limited inventory has pushed prices higher, with sales above $10 million rising sharply year over year. One property currently on the market in Aspen is listed for as much as $300 million, underscoring how the ceiling for ultra-high-end deals in the region continues to rise—even as Karp’s $120 million purchase now stands as the definitive record for homes actually sold.
