AFAIK, they don't have one. Have you seen anything on their positions?
When the month ends, whatever the GME close is, they are on the hook for 140% of the stock (which is both absurd and true).
Why would Citadel, or anyone, be on the hook for 140% of the stock?
Because that’s what Citadel did. They shorted GME. That’s what this is all about.
