Some traders are making millions or tens of millions of dollars on their GameStop holdings, while several hedge funds are losing billions of dollars. A huge number of small retail traders have been taking it to the billion-dollar hedge funds that have large short positions in GameStop, and these retail traders are a vicious pack out for blood. This zero-sum battle between small retail investors taking long positions (betting the stock will go up) and big money hedge funds on the short side of the trade (betting the stock will go down) led to a massive short squeeze that propelled the price of GameStop into a parabolic move to the moon.
