Conflicting reports have valued Zynga at a range of $7-10 billion.
Earlier in the week the Wall Street Journal claimed Zynga was to receive $250 million in a new investment round – putting its value at $7-10 billion.
The new investment “could pave the way for an initial public offering next year”, the New York Times said.
Zynga has attracted enormous investor interest since it was founded in 2007.
The Facebook games studio has multiple studios across continents and in major cities. It has fuelled its studio acquisition spree with huge investment deals said to rise above $800 million in total.
As Zynga is a privately-listed outfit, its revenues and profit margins have been a matter of intense speculation.
The latest prediction, from the Wall Street Journal, is that the firm generated $400 million in profit from $850 million in revenue last year.
