While the company doesn’t name Elon Musk directly, Twitter is clearly trying to prevent the billionaire from buying the social network. > Elon Musk currently owns 9.2% of Twitter. Yesterday, he made an offer to acquire 100% of the company’s shares as revealed in a filing with the U.S. Securities and Exchange Commission. Musk has said he is willing to pay $54.20 per share. It would be an all-cash offer that values the social network at $43.4 billion.
