SpaceX remains a privately held company and has not yet gone public. There is no completed IPO, no stock pricing at $135 per share, and no $1.77 trillion valuation from a public offering. Elon Musk is not a trillionaire. While there has been speculation and discussion about a potential future SpaceX IPO, nothing of that scale has actually happened. Any claims about employees becoming millionaires from such an offering or it being the largest IPO in history are based on a scenario that hasn't occurred.
