## A 73% haircut
Bill Koch listed his Aspen compound at $125 million. It sold at auction in July for $33.5 million, nearly $100 million under the ask.

> the winning bid was $33.5 million, a 73% decrease from its peak listing price
## Bought cheap in 2007
The Oxbow Carbon founder paid $26.5 million for the ski-town property in 2007, then bolted on another 31 acres.
## Ten years of price cuts
It hit the market at $100 million in 2015, dropped to $80 million in 2016, and still found no buyer.
## Selling off the edges
In 2020 he unloaded the extra 31 acres for $14.5 million, keeping the lodge and the remaining 52-acre estate.
## The auction gamble
After a failed $125 million relist in 2025, Koch turned to auction in 2026, a tactic reserved for properties too notable to sit quietly.

## What the buyer got
A 16,600-square-foot main lodge, seven cabins including one built as a gym, hot tubs, hiking trails, and a room for acclimating to altitude.
## Key takeaway

A trophy asking price is a wish, not a valuation. The market decides, and at the very top there are only a handful of buyers to decide with.
