Is SpaceX owned by?

Could you please clarify for me the ownership structure of SpaceX? I'm curious to know who the major shareholders are and if there are any prominent individuals or institutions that hold significant stakes. Additionally, I'm interested in understanding if SpaceX is publicly traded or privately held. It would be great if you could provide a concise but comprehensive description of the ownership details of this influential company. Thank you for your assistance in clarifying this matter.
