Did Elon Musk pay for SpaceX?

Could you clarify the meaning behind the statement "Did Elon Musk pay for SpaceX?" Is the question implying that Elon Musk single-handedly funded the entire company SpaceX, or are we asking if he contributed financially to its establishment and ongoing operations? It's worth noting that SpaceX, like many startups, likely received funding from a variety of sources, including venture capitalists, private investors, and possibly even government grants. Elon Musk's personal investment in SpaceX is significant, but it's unlikely that he paid for the company entirely out of his own pocket. Is there a specific aspect of SpaceX's funding history that you're interested in understanding further?
