How to Invest in Private Space Companies in 2026

SpaceX grew and achieved its milestones for over a decade as one of the leading private space companies. Each successful launch and landing increased the appetite for the still-private stock. Retail was blocked from access without accreditation, including a dedicated marketplace account and a five-digit minimum purchase. 

In 2026, anyone with a brokerage app can trade the now-public SpaceX (Nasdaq:SPCX). The sudden shift also drew attention to other private space companies and the opportunity for early ownership. Some private space companies may repeat the listing process of SpaceX, but for others, potential traders are still facing steep limitations and the strict thresholds for accredited investors. Previous IPO decisions also do not guarantee a similar access level. Pre-IPO opportunities also come with various risk levels and no guaranteed access to owning the actual shares. Pre-IPO pitches do not overrule the existing limitations on accredited buyers.
