SpaceX's super IPO boosts Musk to become the world's first trillionaire.

SpaceX, a huge corporation covering rockets, satellites, and artificial intelligence, raised a record $75 billion through its first public offering on Thursday, highlighting investors' high enthusiasm for its business projects. SpaceX, together with the electric car manufacturer Tesla, form the core of Musk's business empire. Before the stock offering, Forbes estimated his net worth at around $780 billion, far surpassing the second-ranked Google parent company Alphabet's co-founder Page, whose net worth has been around $300 billion. "The second richest person's net worth has always been around $300 billion, which is less than a third of Musk's potential wealth tomorrow," said Forbes wealth deputy editor Matt Durot. "In history, only one other person has reached $400 billion." Most of Musk's current wealth comes from SpaceX, with his holdings worth approximately $866 billion. According to Forbes and Reuters estimates based on company disclosures, with the company's stock trading starting on Friday, along with Tesla and other assets, Musk's total net worth will exceed $1.1 trillion.
