A billionaire wanted $125 million for his Aspen compound. He got $33.5 million.

Bill Koch finally offloaded his Aspen, Colorado, but not for the $125 million he had hoped for.

Shawn O'Connor Bill Koch's Aspen compound sold at auction for $33.5M, far below its onetime $125M asking price.

The property spans 52 acres with a main lodge, seven cabins, and numerous luxury amenities.

Koch bought the compound for $26.5M in 2007, but couldn't find a buyer by listing it traditionally.

Billionaire and member of the famed Koch family Bill Koch tried to offload his massive compound in Aspen for nine figures, but ended up selling it at auction for nearly $100 million below the listing price.

The founder of Oxbow Carbon bought the ski-town property in 2007 for $26.5 million and later added 31 acres.

The compound hit the market in 2015 with an asking price of $100 million.

Koch eventually dropped the price to $80 million the following year.

In 2020, he sold the additional 31 acres he added for $14.5 million, but held on to the lodge and the rest of the 52-acre property.

In 2025, Koch relisted the property at $125 million, but it didn't sell.

In 2026, Koch went the auction route — a tactic sometimes employed for notable properties .

The property finally sold in July, but for a fraction of its original listing price.

The Wall Street Journal reported that the winning bid was $33.5 million — a 73% decrease from its peak listing price.

Koch's lofty $125 million price would have been the most expensive sale in Colorado history, beating Palatir Alex Karp's recent $120 million ranch purchase in nearby Snowmass, Colorado.
