The Phantom Billionaire Who’s Richer Than Warren Buffett

A practically unheard-of billionaire, Amancio Ortega, just blew past household name Warren Buffett to be the second-richest man in the world, according to Bloomberg. Microsoft founder Bill Gates, who is worth $85.5 billion, remains first.

Oretega, who has amassed a net worth of $71.5 billion, is the founding chairman of the Inditex fashion group, the world's largest apparel retailer. Inditex is best known for its chain of Zara clothing and accessories shops, which had sales of $19.7 billion in fiscal 2014.

Worth noting is that Warren Buffett, whose net worth of $70.2 billion puts him at third place, would be in second-place if not for his philanthropic giving.

A native of Spain, Ortega refuses almost all interview requests and until 1999, no photograph of him had ever been published. However, Zara is not so low-profile. The world's biggest fashion retailer operates over 6,600 stores in more than 88 countries.

Inditex has shown strong growth year over year. In March, it reported net profit up 5 percent from the previous fiscal year. In addition, the company said it planned to open up 480 more stores this year.
