BBBY announced a buyback of 2/3rds of their outstanding shares yesterday which triggered an 80% jump after hours in their stock price. There is a theory that GME is being shorted through equity basket swaps. The theory is there are also other "meme stock" companies within these baskets. Yesterday when BBBY jumped big AH so did BB, AMC, KOSS, etc.
Also of note, GME trade volume was almost 5x the entire daily average in the first hour of trading today. This plays into the rehypothecated shares theory.
