Roaring Kitty (Keith Gill) made significant money on GameStop (GME) by starting with a modest investment in 2019, believing the stock was undervalued, and then leveraging options trading to amplify gains as retail investors rallied around the stock, causing a massive short squeeze in 2021, and again in 2024, turning his initial ~$50k into tens of millions, potentially over $200M, through his conviction and social media influence, not illegal manipulation.
How Roaring Kitty's wealth went from $53,000 to nearly $300 million — and could one day top $1 billion.
A screenshot on Monday revealed that he made $54 million worth of gains on paper during just one trading session. Gill posted a fresh image on Thursday showing that he has not sold any of his GameStop position since the Monday screenshot and that his holding is now worth more than $500 million.
Jaydyn Carr was a GameStop shareholder long before the buying frenzy that sent share prices skyrocketing, and now the 10-year-old investor has cashed in, making almost $3,200.
During the height of the squeeze, Melvin was reportedly losing more than a billion dollars a day. The short position adopted by Melvin Capital and others resulted in more than 139% of existing shares of GME being shorted, making GameStop stock the most shorted equity in the world.
What is Keith Gill's net worth in 2025? If Gill's Gamestop position hasn't changed since he last made it public in June 2024, he owns 9 million shares, which as of early 2024, would be worth around $275 million. If Gill still holds both of these stock positions, his net worth could be around $580 million.
The "24-year-old trader making $8 million" refers primarily to Jack Kellogg, a successful day trader who reported over $8 million in gains from trading in 2020 and 2021, starting with just $7,500 and leveraging key indicators like VWAP, support/resistance, volume, and linear regression for simple, adaptable strategies. His story highlights achieving significant returns by weathering different market conditions, learning from losses, and sticking to core principles rather than overcomplicating things.
Gill caused a spike in Chewy's stock price, along with that of rival Petco Health and Wellness (WOOF), in June when he posted a comic picture of a dog on his X site. They rose again in July when it was revealed Gill held a 6.6% position in Chewy, owning 9 million shares worth about $245 million at the time.
#7: Gill's Sister Passed Away
Keith and Kevin lost their sister Sara Gill on June 25, 2020, at age 43. The movie mentions that her death was unexpected, but it doesn't delve into how Sara died.
Yes, Daymond John is still very rich, with an estimated net worth of around $350 million, built from his iconic FUBU brand, his role on Shark Tank, and various other ventures like The Shark Group, speaking, and authoring. He's considered a centi-millionaire and continues to be an active investor and entrepreneur.
The biggest Shark Tank miss is widely considered to be Doorbot (now Ring), which the Sharks passed on in 2013 but was later acquired by Amazon for $1 billion in 2018, a massive missed opportunity for the investors. Another significant missed deal, though not a "missed company" but a rejected offer, was the founders of Coffee Meets Bagel turning down Mark Cuban's record $30 million offer for the whole company, though they raised millions in later funding, says Entrepreneur.
While the short squeeze was initially reported as being driven by retail investors, it later emerged that a substantial part of the market activity surrounding GameStop and the related securities was conducted by hedge funds, who had made substantial profits from the short squeeze.
