Tesla and Space X CEO Elon Musk, a South African, today made a public offer to buy the entire social network Twitter for $54.20 in cash per share, which is expected to total $41.39 billion.

Musk's offer price per share represents a 38% premium over Twitter's closing stock price on April 1, the last trading day before the public announcement of the Tesla CEO's more than 9% investment in the company, according to the Daily Mail.

He is already the social network's largest shareholder, but he turned down a seat on the board of directors, which would have prevented him from amassing more than 15% stake.

Musk reportedly sent a letter to Twitter CEO Bret Taylor stating that he decided to invest in the social network because he believes in the platform's "potential" for free speech around the world. It seems that his expectations were dashed.

""However, since I made this investment, I now realize that the company will never serve that social purpose in its current form. Twitter needs to be transformed into a private company," the international media can read.

Now the richest man in the world wants to buy the whole network for himself.

"Therefore, I am offering to buy 100% of Twitter for $54.20 per share in cash, a 54% premium on the day before I start investing in Twitter and a 38% premium on the day before my investment is publicly announced," the South African CEO is reported to have written.

"This is the last and best offer I can make, and if it is not accepted, I will have to consider my position as a shareholder," he added.

Analysts were already predicting that Musk would ultimately seek, by all means, to buy Twitter for himself.
