The Tesla CEO’s businesses and wealth have made him a celebrity, but his private life has also courted attention thanks to relationships with Grimes and Amber Heard and reports of lovechildren with senior Neuralink executive Shivon Zilis.
In April 2022, Mr Musk launched a controversial buyout of Twitter - a deal that he said would lead to a fundamental reset of the social media platform’s freedom of expression policy.
However, after announcing the pause of his bid in May, he has since said he wishes to drop out of the deal altogether - although legal action by Twitter could still force the takeover to happen.
So, why has Elon Musk ended his Twitter takeover bid - and what could happen next?
When did Elon Musk launch Twitter takeover?
On 4 April, Elon Musk bought a 9.1% stake in Twitter before announcing that he would seek to purchase the social media giant in a $44 billion (£37.2 billion) deal.
Despite initial resistance from Twitter’s board, including CEO Parag Agrawal, it’s believed shareholder pressure led it to accept the deal of $54.20 a share being offered by Mr Musk.
Over the ensuing weeks, the tech entrepreneur outlined his vision for how Twitter would look under his ownership.
These plans included changes to the site’s free speech policies, and the reintegration of banned figures, such as former US President Donald Trump.
He also said he wanted to “own the libs” with his buyout - i.e. frustrate people who are politically central or left-of-centre.
But in May, Mr Musk began to make statements that fuelled uncertainty about whether he would complete his buyout, including saying the deal was “on hold”.
Why has Elon Musk ended Twitter buyout?
After almost two months of uncertainty, Elon Musk announced he was pulling the plug on his Twitter deal on 8 July.
The stated reason given by Mr Musk’s lawyers was that Twitter had “not complied with its contractual obligations” surrounding his takeover.
In a letter to the US Securities and Exchange Commission, they wrote that Twitter did not provide enough information for the billionaire to “make an independent assessment of the prevalence of fake or spam accounts on Twitter’s platform”.
Fake or spam accounts could be important for Mr Musk’s bid because he has suggested that he wants to monetise the platform’s userbase.
If a high proportion of Twitter’s users are not real people, organisations or companies, it could lower the amount of money he could generate from the site.
For years, Twitter has said in its regulatory filings that it believes 5% of the accounts on its site are fake.
However, some commentators have said they believe Elon Musk’s bid was never truly serious, and may instead have been an attempt to disrupt Twitter or force it to change its freedom of speech policies.
For example, his share price offer includes the number 420 - a reference to weed - that he’s used before in an apparent attempt to troll people.
If Elon Musk’s intention was to disrupt Twitter, he’s certainly achieved his goal.
Since the takeover was announced, the company has brought in a hiring freeze, laid off workers, halted discretionary spending and fired two of its top managers.
Its share price has also dipped from a high of $38.75 when markets closed on 7 July to $32.65 at the close on 11 July.
What has Twitter said about Elon Musk deal?
Immediately after Elon Musk announced his Twitter deal was over, Twitter chair Bret Taylor said the company was “committed to closing the transaction on the price and terms agreed upon”.
He suggested the company would sue the entrepreneur in a Delaware state court if that was not possible.
On 13 July, Twitter took another step towards suing Mr Musk, with Taylor tweeting out a copy of its 62-page lawsuit.
The document opens with the accusation that “Musk refuses to honour his obligations to Twitter and its stockholders because the deal he signed no longer serves his personal interests”.
It continues: “Having mounted a public spectacle to put Twitter in play, and having proposed and then signed a seller-friendly merger agreement, Musk apparently believes that he — unlike every other party subject to Delaware contract law — is free to change his mind, trash the company, disrupt its operations, destroy stockholder value, and walk away.”
It all suggests Elon Musk could be in for a lengthy court battle with Twitter, which could lead to him being forced to buy the company, or face a settlement that could total billions of dollars.
Twitter’s use of Delaware as the legal jurisdiction for the deal is significant, because the state court there has previously forced a company - Tyson Foods - to complete a takeover of another business - IBP - after Tyson attempted to pull out of the deal.
Of course, if Elon Musk wins any court case, he wouldn’t have to pay Twitter anything.
Another potential outcome could be that the billionaire stumps up $1 billion (£840 million) to secure a clean break from the deal.
What memes did Elon Musk respond to Twitter with?
For now, Elon Musk is using memes to respond to Twitter’s legal threats.
In one Twitter post, he used a meme of himself, with the caption: “They said I couldn’t buy Twitter. Then they wouldn’t disclose bot info. Now they want to force me to buy Twitter in court. Now they have to disclose bot info in court.”
He also used a picture of Chuck Norris sitting at a chessboard and captioned it: “Chuckmate”.
