GameStop, Reddit, and the Day Ordinary Investors Took On Wall Street

In late January 2021, a struggling video game retailer with declining revenues and a share price that had languished below $20 for years became the most talked-about stock in the world — and the weapon in a populist uprising against hedge funds. GameStop’s stock price, driven by tens of thousands of retail investors coordinating on Reddit’s WallStreetBets forum, surged from approximately $17 at the start of January to an intraday high of $483 on January 28 — a gain of more than 2,700 per cent in under four weeks. Wall Street had never seen anything quite like it.

The mechanics of what happened are as important as the spectacle. Several major hedge funds, including Melvin Capital, had taken large short positions on GameStop — essentially betting, with borrowed shares, that the price would fall. When the price rises instead, short sellers must buy shares to cover their losses, which drives the price higher still, forcing more short sellers to buy, in a self-reinforcing spiral known as a short squeeze. The WallStreetBets community identified GameStop as a heavily shorted stock and piled in deliberately. Melvin Capital lost approximately 53 per cent of its assets under management in January alone — a loss of around $6.8 billion.

The episode sent shockwaves through financial institutions, regulators, and the media for reasons that went beyond the numbers. For many retail investors involved, buying GameStop was not purely a financial calculation — it was an act of protest. Years of watching hedge funds profit from the decline of beloved companies, and years of feeling locked out of a system designed to benefit insiders, had built up a reservoir of frustration that WallStreetBets provided a vehicle to express. The fact that some retail investors made life-changing sums while hedge funds haemorrhaged billions only amplified the narrative.

The regulatory fallout was swift and contentious. Trading platform Robinhood controversially restricted buying of GameStop at the height of the frenzy, citing margin requirements. The decision sparked fury among retail investors who saw it as evidence of a system protecting institutional interests at their expense. Congressional hearings followed, at which Robinhood’s CEO and Keith Gill — the retail investor known as ‘Roaring Kitty’ — testified. The broader questions the episode raised about market structure and the power of online communities to move markets are still being wrestled with by regulators today.
