Hedge fund Sequoia was shorting GameStop. They did not have enough actual shares to close their position, meaning like sell everything to the people that they promised to sell because they didn't actually have the actual shares in their possession. And somebody figured this out on Reddit somehow and then I can't remember exactly the entire story behind it. Well, the entire Wall Street Med, so they started buying it and therefore driving up the pricebecause eventually they have to close. That's the long and short of what happened.
