The much-hyped mobile game Pokémon GO is now available in a handful of countries around the world, and it's off to a hot start. In just a few hours, Pokémon GO shot to the top of the charts. Although the game is free to download, it generates revenue through microtransactions, and it's currently the top-grossing iOS app.

This is good news for Nintendo, as they invested millions into developer Niantic Labs and helped with development. Following Pokémon GO's release, Nintendo's stock jumped 10% overnight. Google Finance currently has Nintendo's stock as being up 8.94% on the day, and it's at its highest point in a month. After today's stock jump, Nintendo currently has a market cap of ¥2.3 trillion, or just under $23 billion.
