The domain SpaceXSI.com, originally registered in July 2025 for approximately $10, has reportedly been sold for $174,000. The transaction occurred through the marketplace Spaceship shortly after Elon Musk announced plans to rebrand SpaceXAI to SpaceXSI.
The sale follows a recent shift in terminology. On September 29, 2026, a presidential executive order mandated that federal agencies replace the term Artificial Intelligence with Super Intelligence, or SI. On October 4, Musk confirmed on X that SpaceXAI would adopt the new branding.
Prior to the sale, the domain was listed on Spaceship with a buy-it-now price of $174,888. While the identity of the buyer and the final price have not been independently verified by SpaceX or the registrar, the reported figure represents a return of roughly 17,400 times the initial registration cost.
The domain was registered over 14 months before the rebrand announcement, suggesting a speculative investment rather than a registration made after the company's intentions became public. The rapid increase in value highlights how quickly corporate branding shifts can impact the price of digital assets.
