GameStop’s share prices spiked Monday after the trader who spearheaded a 2021 frenzy that sent the video game retailer’s stocks soaring returned to social media for the first time in three years.

Keith Gill, known as “Roaring Kitty” on X, had disappeared from the platform after posting a video of kittens falling asleep in June 2021. But on Sunday, Gill seemingly reemerged, posting an image of a video game player suddenly moving from a slouched position to one of straight-backed attention. The meme, which is nearly identical to one GameStop posted in February with the caption “Casual to Competitive,” sent the retailer’s shares skyrocketing once again.
