Twitter stock jumps after Elon Musk takes 9 percent stake in company

Twitter shares rose more than 20 percent Monday morning on news that Tesla CEO Elon Musk acquired a 9.2 percent stake in the social media platform.

Musk is now the largest outside shareholder, with 73,486,938 shares, according to a Securities and Exchange Commission (SEC) filing released Monday.

The Tesla chief is a very active Twitter user with a committed fan base. Just last week, he polled his 80 million followers on whether the platform “rigorously adheres” to principles of free speech.

More than 70 percent responded “No,” prompting Musk to ask whether a new platform is needed.

Musk has previously gotten into hot water over his tweets and is currently in a legal fight with the SEC over an agreement restricting his posts about Tesla.

The deal to acquire a stake in Twitter comes months after longtime CEO Jack Dorsey departed the company.

Parag Agrawal replaced Dorsey in November, prompting Musk to tweet a meme depicting Agrawal as Joseph Stalin and Dorsey as Soviet secret police chief Nikolai Yezhov being pushed into water.
