GameStop's implied volatility explosion based on a single tweet from a r/wallstreetbets veteran adheres to the purest form of a mania-like phenomenon that is unfolding before our eyes today.

For the benefit of those who might not be aware, Keith Gill, who goes by the moniker Roaring Kitty on Reddit's r/wallstreetbets thread, played a pivotal role in unleashing the meme stock mania of 2021 by predicting a massive short squeeze in GameStop's shares at the time. The OG meme stock veteran also pocketed a sizable windfall from that saga, to the tune of around $30 million.

Roaring Kitty's Intricate GameStop Moves

From the 30th of April onwards, someone has been accumulating out-of-the-money calls on GameStop, targeting strikes all the way to the $20 price level.

GameStop Put-Call Skew Sourced From Market Chameleon

This accumulation becomes very evident when one looks at GameStop's 25-delta put-call skew. As can be seen in the chart above, the implied volatility of 25-delta (out-of-the-money) calls has been surging of late, suggesting sustained buying pressure.

Fast forward to Sunday, when Roaring Kitty returned to X after a hiatus of almost three years, posting a picture that indicated he was getting ready for action.

This has translated into a full-blown melt up in GameStop shares today, with call gamma exploding ahead of the regular trading session.

At the time of writing, GameStop shares are up around 80 percent, with at least two volatility-based trading halts already under the belt.

As of the 30th of April, GameStop had a short interest of around 27 percent of its float. We convey our sympathies to the stock's short-seller's today.

News Corp. is currently the smallest company in the S&P 500 index, bearing a market capitalization of just around $14.65 billion. On the other hand, GameStop is currently sitting at a market cap of $9.64 billion. This means that a mere ~52 percent pump from the current levels will allow the meme stock to start eclipsing the market-based capitalization of S&P 500 members.

GameStop's entire option chain for the most recent expiry has entered in-the-money territory!

And, just like that, Robinhood is apparently again placing restrictions on the trading of GameStop shares.

Update 2: GameStop Short-Sellers Are Now Sitting On Steep Paper Losses

According to S3 Partners, GameStop short-sellers were sitting on paper losses for the month of May of around $1 billion in early morning trading when the stock was up around 50 percent. As of 14:56 ET, the stock is up around 75 percent, which means even steeper losses for the short-sellers.
