At 44 dollar a share, Facebook would be worth about 103.5 billion dollars, The New York Post reports.
Before the company filed to go public last week, its shares were selling in the low 30 dollars for much of last year on private exchanges like SharesPost and SecondMarket.
The private market has heated up as shareholders look to sell some stock ahead of an enforced lockup period, while buyers are banking that the shares will pop when Facebook goes public, expected in about May.
