>I don't know how some of these shorts will find 20 million shares by tomorrow.

you're confusing shorts with options. shorts don't expire. They can be held indefinitely as long as you have the margin to keep up with the losses.

If you short more stock than exists, eventually you need to find it. Prime brokers will allow you to naked short but you have to locate shares or buy back in pretty quickly.

Shorts don't expire, but the short sellers can call in on that short and there's also interest at exceptionally high rates.

>There are no set rules regarding how long a short sale can last before being closed out.

>The lender of the shorted shares can request that the shares be returned by the investor at any time, with minimal notice, but this rarely happens in practice so long as the short seller keeps paying its margin interest.
