The SEC has 170k recorded FTDs for GME in the second half of December 2020: https://www.sec.gov/data/foiadocsfailsdatahtm
GME has been on the NYSE Threshold list for months: https://www.nyse.com/regulation/threshold-securities
Multiple WSB users were aware of this public data and that GME had high FTD rates in significantly more favourable circumstances at least as early as October 2020: https://old.reddit.com/r/wallstreetbets/comments/j0ckgf/reg_... https://old.reddit.com/r/wallstreetbets/comments/jbvwek/fail...
There was no reason to not be ass-naked or close to it on the high end of GME call contract writing a few months ago. They've probably covered (at least partially) by now, but that doesn't mean it hasn't happened.
