A potential SpaceX IPO could create thousands of millionaires, according to reports. More than 4,400 current and former employees may see their stock holdings cross the $1 million mark if shares list at around $135. At that valuation, SpaceX could be worth nearly $1.8 trillion, with about 400 employees potentially holding stakes exceeding $100 million-marking what could be one of the biggest wealth-creation events from a public offering.
