The $100 million mansion

The $100 million price tag marks the most expensive single-family home ever sold in the United States. Yuri Milner’s new mansion stands in Los Altos Hills, Calif., in Silicon Valley, a 25,500-square-foot monster with every amenity fathomable. In fact, the French-inspired chateau sounds more like a hotel when listed on paper: just a few of its features are a ballroom, wine cellar, two pools and a tennis court.
