Facebook is now worth a staggering $50 billion (USD), according to new figures released yesterday (Tues).
The world's biggest social networking website - which has 500 million users worldwide - held a share auction last week where 1.9million shares were sold at $20.76 each.
There are an estimated 2.5 billion shares in the company - giving the business a current value of $51.9 billion USD, or #33 billion pounds sterling.
This means the site is now worth just over a quarter of the value of Google - currently around $186 billion - and just under a quarter of software giant Microsoft at $216 billion.
The figures mark a staggering six years of growth for Facebook, which was launched by Harvard student Mark Zuckerberg in 2004.
The story behind the website was recently made the subject of Hollywood film with The Social Network hotly tipped for Oscar glory next year.
Zuckerberg, 26, is the world’s youngest self-made billionaire with a fortune thought to be in the region of $7billion USD.
