Tesla CEO Elon Musk becomes Twitter’s most significant shareholder after buying 73.5 million share

Tesla CEO Elon Musk acquired a 9 percent stake in Twitter to become its largest shareholder at a time when he is questioning the social media platform’s dedication to free speech and the First Amendment.

It’s unclear just when Elon Musk bought the stake. A U.S. Securities and Exchange Commission filing made public on Monday says the event triggering the filing happened March 14.

In a note to investors, CFRA Analyst Angelo Zino wrote that although Musk’s intent is unclear, Twitter could be viewed as an acquisition target because the value of its shares have been falling since early last year.

Elon Musk actual investment is a very small percentage of his wealth, and an all-out buyout should not be ruled out,” wrote Zino, who covers Twitter and social media.

Musk ended up selling more than 15 million shares worth roughly $16.4 billion. With some sales in late December, Musk is close to selling 10 percent.

Billionaire Elon Musk has reached an agreement to acquire Twitter for approximately $44 billion.

After transaction, Twitter will become a privately held company. Stockholders will receive $54.20 in cash for each share.
