Famed Reddit trader Keith Gill has increased his stake in GameStop, according to a screenshot he posted to Reddit on Friday.

Gill, who goes by Roaring Kitty on YouTube and Twitter and DeepF---ingValue on Reddit, now owns 100,000 shares of the video-game retailer, representing a double of his previous common share stake of 50,000 shares. Gill also owns call options on the stock, worth about $1.5 million as of Friday.

In total, Gill's current stake in GameStop, between his stock and call options, is worth about $5.5 million. Gill has already realized profits in his GameStop investment of more than $10 million.

Gill initially invested in GameStop in June 2019, when shares were trading below $10. Last month, the stock topped out at $483 after an epic short-squeeze was sparked by members of Reddit's WallStreetBets forum. Gill's initial $50,000 investment in GameStop was briefly worth $48 million amid the short-squeeze frenzy last month.

Gill testified to Congress last week and explained his bullish thesis on GameStop, which is predicated on a potential turnaround in the retailer, a shift to e-commerce sales, and the renewed video game console sales cycle from Sony and Microsoft.

Shares of GameStop traded up as much as 20% on Monday.
