In basic terms, each bitcoin is currently worth about $1050, so 16 million bitcoins are worth about $17 billion. If you add $10 billion to that, then each bitcoin would be worth about $1690.
This is in the case of a pure market. It would be much more for me, since if there is a constant buying, other people will start buying by fearing to "miss the train". And I would consider the supply to be a lot less than 16 millions since there is several millions of bitcoins that are sitting in addresses, so that are not counted in the mass calculation. I would say at least 2000$ but that would be much more. I could not tell you how much though.
