Who is SpaceX owned by?

Could you please clarify for me who exactly owns SpaceX? I understand that it's a company focused on space exploration and commercialization, but I'm curious about the ownership structure and who ultimately has control over the company's decisions and direction. Is it a privately held company with a single owner, or is there a group of investors or shareholders involved? I'm interested in understanding the business model and how it relates to the ownership of the company. Thank you for your time and consideration.
