What happens if a huge number of stocks is being sold at any price?

What would happen in Jeff Bezos would sell all of his shares of Amazon for any price available (market order)?
All of the current open positions would close and the stock would quickly drop significantly. But would it reach 0 $, or it would stop before? Then anybody who would like to buy at any price would instantly get their order filled. So by my logic the stock price would go to 0 $. Obviously this would be a bad idea from Jeff Bezos, but theoretically what would happen?
