According to a regulatory filing posted Monday, Musk has purchased a 9.2 percent stake in the company.

The company's largest individual shareholder is Musk, who has a stake of about $2.89 billion. Large funds from investment companies are among the major shareholders.

The move came about a week after Musk criticized the social network for not being democratic enough. He asked his followers if they believe that the principle of free speech is essential to a functional democracy, and if they agreed.

The majority of the people who voted did not approve of Musk building a new social media platform.

It appears that Musk is more interested in changing the look of his account. While owning 9.2 percent of the company doesn't give him the power to completely change the company as he pleases, it will probably make him able to influence the company's decisions in the future. We would expect this passive stake as just the start of broader conversations with the board/management that could ultimately lead to an active stake.

Musk uses a variety of methods to communicate with the public, and his main mode of communication is on social media. The CEO of the electric car company got into trouble when he said he was taking the company private with little to back it up.

The story is developing.
