Facebook CEO and co-founder Mark Zuckerberg had a phenomenal 2013. His net worth increased around $12.4 billion, according to data compiled in the Bloomberg Billionaires Index. This is the largest gain than any current tech executive, excluding Bill Gates. Zuckerberg now has a total net worth of over $24.5 billion. The increase in Zuckerberg’s net worth is largely due to the increase in Facebook’s stock price.
Facebook went from around $27 to $54 in the year 2013. The stock price grew because investors grew their confidence in Facebook being able to monetize from mobile devices. The more Zuckerberg made, the more he wanted to give back. This is why Zuckerberg and his wife Priscilla Chan donated around 18 million shares of Facebook stock to charity.
Zuckerberg is also part of Bill Gates’ Giving Pledge, which is an initiative to give away most of his wealth to charity as time goes by. Bill Gates saw his net worth increase around $15.8 billion due to Microsoft’s stock price increase. Tesla Motors CEO Elon Musk saw his net worth increase 233% during the year, which is the largest percentage increase of every billionaire on the list as driven by the stock price increase of the auto company.
