Exchange rate – how much would a millionaire (in BTC) cost?

You know how people talk about how they want to have a million dollars? Well, I have a much more golden question. How much would it cost to get a million Bitcoins? That number (unless you have access to all the world's Crypto Dark Pools) is likely to be in excess of $ 7.5 billion, as the stock markets would multiply that price. Do the stock markets even have enough BTC to do this? Note: This does not have to be done exclusively through sharing and I just want one answer. My address needs more than a few pennies, help me to be a future millionaire.
