SpaceX's IPO is set to be the biggest ever and could make Elon Musk a trillionaire

SpaceX says it plans to raise up to $75 billion when it goes public this month, setting the stage for the largest-ever stock market debut and putting Elon Musk on course to becoming the world's first trillionaire. The company, formally known as Space Exploration Technologies Corp., said Wednesday it will sell 555.6 million shares at $135 a piece. The offering would give SpaceX a market value of $1.77 trillion.
