SpaceXSI.com Reportedly Sells for $174,000 Following Elon Musk's Planned Rebrand

A domain name registered in July 2025 for roughly $10 has reportedly sold for $174,000 after Elon Musk confirmed plans to rebrand SpaceXAI to SpaceXSI, according to reporting by Tech Startups (https://techstartups.com/2026/10/07/a-10-domain-just-sold-to-elon-musk-for-174000-after-spacexais-surprise-rebrand/).

The transaction for SpaceXSI.com was executed through domain registrar and marketplace Spaceship, as announced by the @domain account on X on October 7, 2026. The post named Musk as the buyer. Neither SpaceX nor Spaceship has independently confirmed the purchaser's identity or the final transaction terms.

Registry records show that SpaceXSI.com was registered on July 25, 2025, more than 14 months before the recent naming controversy. At the time of its initial creation, no corporate entity named SpaceXSI existed publicly, and Musk had given no indication of adopting the name.

The domain's market profile shifted rapidly after a policy change in Washington. On September 29, 2026, President Donald Trump signed an executive order directing federal agencies to use 'Super Intelligence' and 'SI' instead of 'Artificial Intelligence' and 'AI' in official executive branch communications, digital portals, and non-statutory documents. The order did not apply to commercial businesses.

Musk adopted the revised terminology days later. On October 4, Musk wrote on X, 'No more AI. SI. It’s better.' When asked if SpaceXAI would be renamed to SpaceXSI, Musk confirmed, 'Yes, we will make that change,' a shift also reported by Reuters.

Technology news outlet The Register noted on October 5 that although Musk announced the SpaceXSI branding, he had set no formal transition date, and the exact-match .com address remained listed on Spaceship with a $174,888 'Buy Now' price tag.

The domain's July 2025 creation date indicates the sale was the result of speculative holding rather than reactive domain squatting following Musk's announcement. At an original registration fee of approximately $10, a $174,000 gross transaction yields roughly 17,400 times the initial cost, excluding renewal fees and marketplace commissions.
