Elon Musk Is the World's First Trillionaire

SpaceX's stock market debut has thrust the richest man in the universe into an unexplored frontier of wealth. There are thousands of billionaires across the world. But there is only one trillionaire. Elon Musk became the first person to amass a personal fortune of over $1,000,000,000,000--that's 12 zeros--after shares of his rocket company SpaceX debuted on the Nasdaq stock exchange on Friday. SpaceX's initial public offering on Thursday valued the company at nearly $1.8 trillion, up from its most recent private valuation of around $1.25 trillion.
