Earlier quoted context omitted.
The second that the shorts have covered the price isn't going to drop to $90, it's going to drop back to $20 and most of the WSBers who were holding out for $2000 will lose their shirts. The shorts are going to lose, no doubt. But once they've lost, the stock price is probably $20. A lot of WSBers are going to be holding stock at that point, and possibly on margin. And that stock is going to be a crappy retail stock.…
You're forgetting the stock is 125% over shorted. There literally isn't enough stock for shorts to cover their current positions. That's why there is potential for infinite, (huge) gains as long as everyone holds.
The sensible people will take their (massive) profits, and those who believe the "as long as everyone holds" rhetoric will be left with losses, probably on margin.
