I’m not so sure they closed out 100% of their short. Not that it matters to me. I just don’t believe so much in the media nowadays.
If you look at the Wallstreetsbets reddit board, there is “trader” claiming they only closed out a small portion of the shorts. According to him, they are spreading disinformation (who would think) that they settled there obligations in order to trick the people holding the stock to sell it. Personally I believe this based on all the fraud that is put before the american people.
