With Elon Musk owning SpaceX, Tesla and Twitter to name just a few, he's got countless sources of income and there's no wonder the entrepreneur has surpassed $400,000,000,000 net worth.
The billionaire reached the historic wealth marker this week, making him the first person in history to ever have a net worth so high.
According to the Bloomberg Billionaires Index, the 53-year-old is now worth an incredible $447 billion as of December 11, which is $198 billion more than the second richest person in the world Jeff Bezos at $249 billion.

Although if we go off Forbes' rich list, he is only worth a mere $379.4 billion - pathetic.
What is almost unbelievable though, is that just three weeks ago we published how he was worth $315.7 billion meaning that he's incurred $63.7 billion... again, according to Forbes.
Meanwhile, Bloomberg's records state that since Election Day, dominated by President-elect Donald Trump, Musk has become roughly $136 billion richer.
And he even has a role in the White House.
"I am pleased to announce that the Great Elon Musk, working in conjunction with American Patriot Vivek Ramaswamy, will lead the Department of Government Efficiency ('DOGE')," Trump wrote at the time.
The President-Elect went on to explain that the pair would 'pave the way for my Administration to dismantle Government Bureaucracy, slash excess regulations, cut wasteful expenditures, and restructure Federal Agencies – Essential to the 'Save America' Movement'.
As well as Tesla, SpaceX and Twitter, Musk also owns artificial intelligence company xAI, American infrastructure business The Boring Company as well as tech-company Neuralink.
In its own words, Neuralink states: "We are currently focused on giving people with quadriplegia the ability to control their computers and mobile devices with their thoughts."
Musk also owns a healthy share of cryptocurrency including Dogecoin, designed initially to make a joke of the crypto system using a popular internet meme of a dog.
His upcoming role as the US' head of the new Department of Government Efficiency (DOGE) is actually named after the memecoin.
Last week, Musk's record-breaking $56bn payout was denied for a second time, with a judge ruling against the richest man in the world.
Musk was set to receive the $56bn in pay from Tesla under a historic compensation package struck in 2018. It was described in court documents as the largest ever seen in public markets.
However, Judge Kathleen McCormick called Tesla’s legal argument ‘fatally flawed’ and at times ‘indefensible’ as she denied the motion in a 101-page opinion.
