The historic GameStop phenomenon occurred when a massive coalition of retail investors on digital forums identified that more than 140 percent of the company's public float had been sold short by institutional hedge funds. Coordinated buying pressure, fueled heavily by options market mechanics and viral social media sentiment championed by traders like Keith Gill, forced short sellers into a violent scramble to buy back shares. This buying frenzy triggered a historic short squeeze that drove the share price up by thousands of percentage points in a matter of weeks, causing widespread market disruption and regulatory evaluations.
