Pokémon Go is the latest hotness in mobile gaming and Nintendo is basking in its glow -- to the tune of $7.5 billion in additional market value. Nintendo stock closed up 25 percent on Monday, and by the end of last week, when Pokémon Go hit mobile devices across the US, Australia and New Zealand, the company's stock was already up 9 percent.
Nintendo added $7.5 billion to its market value on Friday and Monday alone, Reuters reports. Nintendo didn't directly develop or publish Pokémon Go, but it holds a large stake in the series' licensor, The Pokémon Company. Pokémon Go was developed and published by Niantic Labs, Google's former AR division that was responsible for the Ingress mobile game. Nintendo and Google invested an estimated $30 million in Niantic while it was working on Pokémon Go.
