Musk made a final offer to buy the company and said he would make it his own.

Musk made the offer in a filing with the SEC. The billionaire disclosed a stake of 9% on April 4.

The executive is one of the most popular firebrands on the social media site, and often uses his platform to make fun ofelonmusk. He was the largest individual shareholder and the company offered him a seat on the board.

After his stake became public, Musk immediately began appealing to fellow users about prospective moves, such as turning San Francisco headquarters into a homeless shelter and adding an edit button to his account. Several celebrities with high numbers of followers rarely use the social networking site.

Musk can pay for it. He is currently worth $260 billion according to the Bloomberg Billionaire's Index, which is less than the market value of the micro-messaging service.
