The Reddit poster and YouTube streamer who caused a Wall Street crisis by driving up the price of GameStop – and boasted about his $47 million gains – is a suburban financial adviser who nicknames himself Mr. Wizard, DailyMail.com can reveal.

Keith Gill, 34, is the man behind the Roaring Kitty YouTube streams and the DeepF***inValue Reddit posts which caused a buying frenzy for stock of the ailing retailer, and cost hedge fund billions.

Gill, a married father-of-one who lives in a three-bed home in Wilmington, Massachusetts, is a MassMutual financial adviser who drove the frenzy of buying by Robinhood investors which has roiled the stock market and is now the subject of SEC and Senate inquiries.

On Wednesday, as the stock price soared, he posted a screenshot which showed how he had invested a total of $745,991 investment - and at that point it was worth $47,973,298.

A hedge fund which had bet that GameStop's share price would go down was left seeking a bailout of its own from other hedge funds, and the frenzy spread to other stocks including AMC and on Thursday morning, American Airlines.

But by Thursday the sudden surge in price had become a full-blown regulatory crisis, Robinhood barred trading of GameStop – to the fury of users and politicians ranging from AOC to Ted Cruz - and Gill himself could be part of the SEC investigation. 

It could also face legal action from users furious that they cannot trade. 

The saga began with Gill posting a video on his YouTube channel for investing and finance tips in August, suggesting GameStop was undervalued.

But as the stock got taken up by millions of everyday investors, coordinating via the Reddit subgroup Wall Street Bets and some gambling their life savings against Wall Street veterans who were heavily shorting the company, Gill was soon being held up as the messiah of the financial flash mob movement. 

The unassuming financial advisor is a far cry from the Wall Street lords he has been pitted against.
