It would make Facebook one of the biggest technology companies in the world, overtaking Amazon and Cisco, reports the Daily Mail.
That estimate puts its profits far above the numbers Facebook released in January 2011 when Goldman Sachs and Russian investment firm Sky Technologies invested 1.5billion dollars in the firm.
The terms of their investment implied it could be worth as much as 50 billion dollars.
Facebook's rapid growth has fuelled a scramble among investors to buy shares in the company while it remains private.
Much of its success is down to its huge advertising revenue, which is predicted to hit 4.05billion dollars this year, up from 1.86billion dollars in 2010, according to EMarketer.
It has also made extra money from its own payments system, called Credits, for which it takes a 30 percent cut.
The people who leaked the figures stressed that it was difficult to assess Facebook's value, because it will depend on the economic mood at the time of its IPO. (ANI)
