Roaring Kitty Returns as Meme Stocks GameStop and AMC Surge at Market Open

The man at the center of the pandemic meme stock craze, Keith Gill, also known as “Roaring Kitty,” made a triumphant return to the social platform X after three years, sending prices of some of those stocks soaring at the opening bell on Monday.

Gill posted an image on Sunday of a man sitting forward in his chair, a meme used by gamers when things are getting serious. He followed that tweet with a YouTube video summarizing the bull case for GameStop, the struggling video game retailer that he helped revive in 2021.

At Monday’s opening bell, shares of GameStop surged nearly 50%, marking its biggest intraday jump since the meme craze in 2021. Other meme stocks like AMC Entertainment Holdings Inc. also saw significant gains.

Gill became a hero to small retail investors in 2021 after his posts on the Reddit subcategory Wallstreetbets sparked a battle against large hedge funds that were betting against GameStop. The small investors ultimately won, driving GameStop’s shares up over 1,000% and other meme stocks as well.

Shares of GameStop, AMC, Koss Co., BlackBerry, and Bed, Bath & Beyond all surged on Monday, with GameStop jumping nearly 70% and AMC leaping 23%.

Gill, who had largely disappeared from messaging boards after the meme craze, made a dramatic comeback that reignited interest in these meme stocks. The story of Roaring Kitty and the meme stock craze was even turned into a movie called “Dumb Money” last year.
