GameStop shares surge nearly 50% after 'Roaring Kitty' teases livestream

• Roaring Kitty schedules YouTube livestream for noon Friday.
• Keith Gill's return to social media sparks rallies in meme stocks.
• GameStop closes at $46.55 per share.

Shares of GameStop surged nearly 50% on Thursday after the online stock influencer known as "Roaring Kitty" posted on YouTube that he would host a livestream on Friday.

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 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%.

Gill developed a cult following of traders who fueled sharp gains in GameStop, which scalded hedge funds that had bet against the shopping mall retailer that was struggling with shrinking sales as videogame fans shifted to online purchases.

Ending Thursday at $46.55 per share, GameStop has surged over 160% in 2024. In 2021, the stock reached an intra-day peak of nearly $121 before tumbling nearly 90% in the following five sessions.

Gill did not immediately respond to a request for comment about the upcoming livestream.
