Nintendo's market value has now risen above $39 billion to overtake Sony – itself on a high after a six month rise.
The chart below shows just how meteoric Nintendo's market value rise has been.
Last week Nintendo set a record for the most shares ever traded in a single day on the Japanese market - 476 billion yen ($4.5 billion) worth of shares were traded on Friday.
Remember all this is happening despite Nintendo only owning around a third of Pokemon Company, which is publishing the new Pokemon GO game. We're yet to hear from Nintendo how the game's success will affect its earnings.
