Golden Finance reports that insiders reveal that SpaceX executives are starting to select Wall Street banks to provide advisory services for their initial public offering (IPO). Insiders say that the investment bank is scheduled to conduct preliminary presentations next week, representing the most concrete step this rocket manufacturer has taken towards what could be a significant IPO. SpaceX informed employees last Friday that the company is preparing for a possible public offering next year. Earlier this month, The Wall Street Journal reported that SpaceX is also seeking a secondary stock sale, which would value the company at approximately $800 billion, up from $400 billion this summer.
