While it is good to see a hedge fund get gamed by a bunch of little guys, in any price wave the biggest beneficiaries are usually small in number but always on the early side of the buying wave. The smartest of them sold their recently bought shares long before the wave hit its high, while the majority will be holding shares bought at prices above what the price will settle down to. Some, with big skin in the game but not with large other assets may have to take losses that collectively may equal or exceed what the hedge fund lost.
And at the end of the day, Game Stop is still a dying business. A brick and mortar retailer of what is now mainly a digital asset. Any executive there with stock is selling it off as fast as they can.
