In just a few minutes, Nintendo will unveil (update: meet the Nintendo Switch) the first official teaser for the Nintendo NX, the company’s next flagship console. While the console isn’t supposed to come out until March 2017, people are excited — including investors.

A few minutes after Nintendo teased the NX preview on Twitter, Nintendo’s shares jumped. The company also unveiled a new Zelda trailer, but we’ve seen Zelda trailers for months already. Nintendo ended with shares up 3.34 percent compared to yesterday’s closing price.

How much can a tweet affect a company? A tweet can be worth $1.36 billion apparently. Nintendo is now worth around $37 billion, and the NX teaser added around $1.36 billion in market capitalization.
