Keith Gill, the former financial analyst known online as "Roaring Kitty," is credited for the GameStop stock surge in late 2020, when he posted on YouTube and Reddit his belief that GameStop (GME) shares were undervalued. Gill bought $53,000 worth of GameStop stock in 2019, valued at $48 million at the height of the GameStop surge in January 2021.

Because much of Gill's net worth seems to be tied to his investment in GameStop, it can fluctuate. After stepping back from the public in June 2021, Gill returned in May 2024 with cryptic memes posted to his X account, followed by snapshots of his GameStop portfolio posted to his Reddit account, DeepF---ingValue, or DFV, in June. Shares of GME surged at the time in response to Roaring Kitty's return to social media and renewed interest in meme stocks.

Gill Owned 9 Million GameStop Shares in June

On June 13, 2024, Gill shared a snapshot of his portfolio on Reddit, showing that his holdings included more than 9 million shares in GameStop, worth $262 million, and another $6.3 million in cash. His overall net worth at that time was about $268 million.

During a YouTube livestream on June 7, 2024—his first in three years—Gill shared his E*Trade portfolio on screen and revealed that his GameStop positions were his only investments.

In July 2024, a Securities and Exchange Commission (SEC) filing showed that Gill also owns a 6.6% stake in pet product retailer, Chewy (CHWY). According to the filing, Gill owns 9 million shares of Chewy. Chewy was founded by billionaire Ryan Cohen, GameStop's chief executive officer (CEO). Gill praised Cohen during his livestream in June.

Gill's role in the GameStop phenomenon made it to the big screen in 2023 with Sony Pictures releasing a film called "Dumb Money," depicting Gill's real-life story and journey during the 2020-2021 GameStop craze.
