Can I buy shares in SpaceX?

Could you please elaborate on the feasibility of investing in SpaceX through the purchase of shares? Given SpaceX's status as a privately-held company, I'm curious to know if there are any avenues for individuals to acquire ownership stakes. Furthermore, what are the potential risks and rewards associated with such an investment? Are there any secondary markets or alternative methods that enable investors to gain exposure to SpaceX without direct share ownership? I'd appreciate your insights into this matter.
