When Elon Musk tweets, the market listens.

Twitter shares skyrocketed Monday as news broke that the Tesla CEO and Twitter obsessive had purchased a 9.2 percent stake in the social media company. At the end of the day's trading, CNBC reported that Twitter stock was up 27 percent — bringing the value of Musk's holding up with it to a staggering $2.89 billion.

That word of Musk's investment would spur a buying frenzy itself is not a new phenomenon. We saw similar activity after the richest person alive announced that his company Tesla had purchased bitcoin, an announcement which immediately proceeded a new record high for the cryptocurrency.

Notably, this all falls barely a week after Musk questioned whether or not Twitter's time had come — on, of course, Twitter.

In the form of 73,486,938 shares of Twitter, it seems that Musk has provided an answer to his own question. That is, unless he intends to liquidate his entire holding, take a substantial profit, and use that to create a new social media platform entirely.

Either way, we're sure to hear about it... on Twitter.
