You know how large investors make money right? One day, Investor "A" wakes up and goes to Taco Bell and orders a dozen double cheese bean burritos. Then he takes a big dump, producing a ten pound steaming pile of shit. And now you have investor B come in, who offers $1 million dollars for an ounce of that ten pound steaming pile of shit. That means investor A is now "worth" a billion dollars, because his ten pound steaming pile of shit is "valued" at a billion dollars (valuation is determined at $1 million per ounce .. ten pounds .. ok I rounded up a little). Anyway, since investor A is now a billionaire, he can afford to purchase an ounce of investor B's steaming pile of shit too. Thus making Investor B a billionaire as well. He can go purchase a $10 million yacht by going to the bank and saying hey give me a loan, I have a ten pound steaming pile of shit that's worth $1 billion.
As for what happens to the pile of shit? Can it be sold? I dunno, who cares?
Now, imagine the pile of shit is a data center.
