Elon Musk just offered to buy Twitter for $43 billion, telling the SEC that the deal would be really good for free speech. Elon Musk said that he invested in Twitter as he believes in the potential of the platform for free speech around the globe, believing that free speech is a societal imperative for a functioning democracy. If this deal goes through, the company is going to be going private.

Also, after this news hit the public, Twitter shares jumped up 18% on the news & Elon Musk implied that if this deal was rejected he would be ready to dump all of his shares. “I am offering to buy 100 percent of Twitter for $54.20 per share in cash, a 54 percent premium over the day before I began investing in Twitter and a 38 percent premium over the day before my investment was publicly announced,” Musk said in the filing. “My offer is my best and final offer.”

In a separate text noted in the filing that included Twitter Chairman Brett Taylor, Elon Musk, put things bluntly as he said, “I have moved straight to the end. It’s a high price and your shareholders will love it. If the deal doesn’t work, given that I don’t have confidence in management nor do I believe I can drive the necessary change in the public market, I would need to reconsider my position as a shareholder. This is not a threat, it’s simply not a good investment without the changes that need to be made.”

All of this started when Elon Musk purchased a 9.2% share and Twitter and was later offered a seat on the board of Directors, after which he declined. Also, adding to the drama, Elon Musk is currently facing a lawsuit from Twitter shareholders for an 11-day delay and officially disclosing his 9.2% investment in the company. Twitter said that the board of directors would carefully review the proposal to determine the course of action.
