Billionaire investor Yuri Milner recently bought a lavish, 25,500-square-foot mansion in Silicon Valley for $100 million, believed to be the most ever paid for a single-family home in the United States.

Milner, who appears on the cover of the most recent issue of Forbes magazine, has invested in Facebook, Zynga and Groupon via his investment firm DST Global; he also built Mail.ru, a Russian Internet company which last year listed on the London Stock Exchange. Milner’s primary residence remains in Moscow, where he lives with his wife and two daughters.

The Wall Street Journal reports that 49-year-old Yuri Milner, an investor in Facebook, Groupon and Zynga, has no immediate plans to move into the home.

Milner is the founder of Digital Sky Technologies, an investment firm he started in 2005.

The mansion purchased by Milner is a French-style chateau set on 18 acres in hills overlooking San Francisco Bay.The estate has a ballroom, wine cellar, gym, spa and pools inside and outside.The Journal says the sale price beats the previous high of $95 million in 2008 for an estate in Palm Beach, Fla.
