If we take ig. They will have a single crest account for most of their clients, if they have more clients long than short then they just use a percentage of the longs to cover the shorts. If they can't do this they stop offering the short.
They make on the deal charges. The spread. The leverage fees on both sides.
It's not a surprise that shorts are falling quite rapidly though as they need liquidity and to be honest this share is running out of liquidity, which will make life hard for them.. not to mention lot potential good news.
