(CNN) - Facebook is now worth more than $200 billion, passing that level for the first time this week.
The social network is now the 15th most-valuable company in the S&P 500 stock index and worth more than much older companies such as IBM, Coca-Cola, AT&T and Disney.
Facebook's stock is up more than 40 percent this year and has more than doubled from its initial public offering in 2012, when it launched at $38 a share.
Analysts say mobile growth and big acquisitions have pushed the company's value sky high. Facebook generates nearly two-thirds of its total ad sales from mobile platforms.
