As someone who is not an investor but has bought into the r/wallstreetbets hype I found if you watch the video Fleury posted from 15:30 - 20 min he does a good job of explaining the GameStop situation in my opinion.
I think the key is that GME was heavily shorted in late 2020 and some people questioned why when the company's financials and situation with new leadership were improving. They invested then convinced others to invest which pushed the stock up and then forced shorts to cover creating a feedback loop. Now people are seeing early investors posting 1000+% gains (there is a guy with a 13 million USD position who started with only 50k in!!) and more are investing. At this point it's obviously overvalued and not surprisingly still heavily shorted so something has to give

In the meantime a few big players have gotten themselves burnt!

As someone who normally doesn't follow stocks it's been very entertaining the last few weeks.
