Pokémon GO has been a massive success, despite the various server issues and international delays. IGN reports that within the first week of the game’s launch Nintendo’s shares jumped over seventy percent, with ten percent of that coming from the first day alone. However the game’s success doesn’t end there. Yesterday, Bloomberg released a graph showing how profitable the game has been for Nintendo.

As you can see from the title, this graph tracks the most traded Japanese stocks in any one day, and according to this, Nintendo beat out companies like Tokyo Electric and SoftBank.

In the article, it’s said that on Friday Nintendo traded more than 476 billion Yen (about $4.5 billion USD) “making it the biggest turnover for any company in the Topix (The Tokyo Stock Price Index) index this century.” Nintendo broke the previous record held by Tokyo Electric.

This is even more impressive considering that Nintendo doesn’t even control the direction of the game. In an IGN article, it’s said that Nintendo only owns a non-majority stakes in Niantic Labs (the game’s developer) and The Pokémon Company (essentially the Pokémon PR company). This means that while Nintendo does keep tabs on the game, it’s essentially up to Niantic and The Pokémon Company where the game goes in the future.

Pokémon GO is one of those rare games that seems to live up to the hype, whether it will continue to be as popular still remains to be seen. At least in the short term this game is quite the cash cow, or cash Miltank.
