tl;dr the stock market has been using fake shares to drive down the price of AMC and probably GME too.
A buyer can borrow shares and immediately sell them which is called a short. it’s a gamble that the stock price will go down. It also puts downward pressure on a stocks price because the market looks at it as a bet on the price going down.
But in the case of meme stocks, like AMC and GME, retail holders have bought a ton of available shares, odds are there isn’t a whole lot of real shares for sale in the market.
So, since hedge funds can’t locate actual shares to borrow to short with, they need to find fake shares which is illegal of course. AMC only has about 500 million shares total. FTX claimed to have 400 million simulated share tokens backed buy real shares which is of course ridiculous. hedge funds apparently have been using these fake stock tokens to satisfy the legal need to locate real shares to short AMC
The moment hedge funds are forced to locate real shares the stock price will explode. Thats what this has all been about.
