You're a fucking idiot. That's not how the stock market works.

When you buy stock, you're not buying it from AMC.

AMC did an IPO that was x shares. That's all there is available. If I buy 10 shares at the IPO, yes, I gave AMC money. But if you want to buy my 10 shares, your money doesn't go to AMC. It goes to me.

AMC has been public since forever.
