Thanks for the explanation! What happens when someone shorts a stock and then the company goes under? In this case of SVB, you short a stock, company gets taken by FDIC, trading is halted and I'm assuming the company will be sold/dissolved? So what happens with the shorts?

At that point, the stock is worthless and the borrower doesn't have to return it. They keep all of the money from the initial sale.
Companies are often in limbo for a long time before they officially go under.
The borrower has to keep paying borrow costs during that time. Which makes shorting companies that go down rather risky.
