Milner’s wealth soared in the mid-1990s as CEO of an investment brokerage owned by Mikhail Khodorkovsky, who famously fell out of favour with Vladimir Putin and spent eight years in prison.
He’s made some extremely astute bets on US social media companies. Milner bought shares in Facebook back in 2009, and held 5.5% of the company as it went to IPO, turning a $200 million investment into well over $1 billion in a few years.
Similarly, on the day of Twitter’s IPO, Milner’s investment in Twitter, (about $400 million in 2011, when it was valued at $8 billion) surged when it floated. The company is currently worth about $26 billion.
