Roaring Kitty Returns: GameStop Stock Up 400% in One Week

The Return of the King
Keith Gill, known as Roaring Kitty, has sent shockwaves through Wall Street with his first social media post in three years — a simple cat picture that triggered an immediate 400% surge in GameStop stock. Trading volume exploded to levels not seen since the 2021 short squeeze, with retail investors piling in once again. The stock, which had been trading under $20 for most of 2025, rocketed past $100 in after-hours trading as the crypto and meme stock communities mobilized.
Gill's return comes as GameStop completed its transformation into a tech company with $4 billion in cash and zero debt. The company has been quietly building a Bitcoin treasury and developing blockchain gaming initiatives. The sudden price action caught major hedge funds flat-footed, with short interest still at 18% despite the run-up. Trading was halted six times on volume exceeding 2 billion shares — the highest single-day volume in history.
Déjà Vu or New Chapter?
Unlike 2021, GameStop now has real fundamentals to support its valuation. The company's cash position could fund aggressive Bitcoin purchases or acquisitions. Ryan Cohen's vision of transforming GameStop into a technology platform appears to be gaining traction. The return of Roaring Kitty has reignited the retail investor revolution, proving that social media influence remains a powerful market force.
