Short sellers notch $8.7B profit as SpaceX shares dip to IPO price

The buyer of your short sale would lose money to you. Remember options are contracts between two parties.

Shorters are selling to willing buyers at the current fair market price. So that they may survive.

Someone who bought and expected to make a profit, but reached a point where they hit their stop loss or just wanted to get out the trade at any cost and couldn’t bear to wait longer. Quite possible a redditor who frequents r/wallstreetbets and YOLOed in.

The person you sold it to after borrowing it, who paid for it at the elevated price.
