It's unknown when SpaceX will go public, and no one in the investment world knows for sure if it will ever happen. Currently, the company can raise sufficient capital to maintain and expand its business.  Unfortunately, successful private companies tend to stay private longer now than in the past, for a decade or longer. SpaceX was founded in 2002, which means it's already entering its third decade as a private company. That doesn’t offer much hope that an IPO will happen anytime soon.
