It is the moment nobody was sure would ever happen: after months of drama, Musk says his $44 billion deal to buyTwitter is complete.
He changed his bio to read "chief twit" and declared "the bird is freed" after announcing the big news on the social networking site. As far as he is concerned, the job has been completed.
It has not been confirmed yet, and the silence from the headquarters has been deafening.
According to reports, Mr Musk has already fired the chief executive, chief financial officer, and legal and policy executive at the company.
What would Mr Musk's account look like?
In a message posted on Thursday, Mr Musk addressed potential advertisers. He stated that he wanted to help humanity and that he wanted a digital town square. He accepted that his mission might not work out.
The fact that he wrote specifically to those who advertise on the social networking site suggests that he intends to stick with his digital advertising business model. As the global financial crisis bites and firms find themselves with less cash to splash on marketing, this revenue is not going to fall for giants likeAlphabet and Facebook.
He has said in the past that he wanted to lighten moderation so that more voices could be heard.
Maybe he will bring back some of the more controversial tweeters, like former US president Donald Trump, who has previously said he had no desire to return, or his friend and fellow musician, Yeezus, who has also previously said he had no desire to return.
I don't know. The platform must remain welcoming, must abide by national laws, and must not become a free-for-all hellscape according to Mr Musk.
I don't think it's right that Mr. Trump was suspended for inciting violence and that West was banned for anti-Semites.
The amount of bot accounts that Mr Musk believes litter the site has always been disputed by the company. He could order a mass kill, but it would probably affect everyone's follower numbers, which could be unpopular.
His most intriguing hint so far is that his company will be called X, the everything app. Many people think that he is referring to the creation of a "super app" similar to China's WeChat, which is a one-stop-shop for social media, messaging, finance, food orders.
One could argue that the West does not have such a thing.
The press release I received said that Mr Musk is a proud investor in the vision of his company.
Is there a way for businesses to accept payments in cryptocurrencies? It would be a hit with fans of the digital currency and a horror for those who warn of its risks.
We don't know much about Mr Musk, but he's visionary, volatile, ambitious, and creative. Some people are saying that the change of leadership will cause them to leave.
"We wanted flying cars, instead we got 140 characters," said the investor Peter Thiel, long before the meme "expectations vs reality" became a thing. We might get both with Mr Musk.
