Thursday’s surge was the latest in a bout of volatile trading in the struggling videogame seller’s shares that kicked off last month after the influencer, whose real name is Keith Gill, returned to X.com after a three-year hiatus.

The "Roaring Kitty" channel on YouTube on Thursday showed an upcoming livestream scheduled for 12 p.m. ET (1600 GMT) on Friday.

On Monday, GameStop shares closed over 20% higher after Gill’s Reddit profile returned with a post showing a $116 million bet on the stock after a three-year gap.

Gill was a key player in the 2021 rally in GameStop and other so-called meme stocks that was fueled by individual investors on Reddit’s wallstreetbets forum.

His recent return to social media rekindled rallies in GameStop, as well as other shares popular with individual traders on social media.

AMC Entertainment jumped 12% on Thursday, while headphone maker Koss rallied 15%.
