Elon Musk's SpaceX begins trading on the Nasdaq exchange on Friday with the biggest initial public offering in history expected to make the polarizing entrepreneur the world's first trillionaire. The company priced more than 555 million shares at $135 each in a filing with the US markets regulator on Thursday, placing SpaceX in the top 10 of Wall Street's biggest companies with a valuation of just under $1.8 trillion -- ahead of Tesla, Facebook-owner Meta and Walmart.
