Facepalm

I genuinely cant understand why stockbros are so fucking obsessed with artificially pumping this shit up with their obsessive memeing

It was actually a bit of legit class warfare. The institutional investors and billionaires were shorting GME so much that they were overexposed, and when u/DeepFuckingValue on Reddit spotted and shared it tons of regular middle-class retail investors all piled in to collectively fuck over the billionaires by pumping the price knowing that the short positions would still have to be filled. Probably some billionaires made money too, but for the most part is was a "regular folk vs Wall Street" affair.

nor do I understand how it hasnt been investigated as a blatant stock manipulation.

They literally hauled u/DeepFuckingValue up in front of a Congressional Inquiry for pointing out on Reddit that a stock was oversubscribed, which is more than they've done for the many questionable insider stock purchases made by politicians and their families in recent years. Indeed, that's a big part of why the story won't go away, because it very publicly proved that the rules only apply if you're not connected.
