Businesses continue to buy aftermarket .ai domains and put them to use.
The artificial intelligence surge has reshaped the domain industry. Companies are actively registering .ai domains, acquiring .com names for AI products, and launching websites built with AI technologies. The volume and pace of these purchases highlight how domain strategy is now integral to AI brand-building and go-to-market plans.
On the .ai side, registrations have surpassed one million domains. Marketplaces have seen substantial aftermarket activity: Spaceship alone has reported more than $3 million in .ai sales this year on NameBio, and that figure represents only transactions recorded publicly.
Buyers are not parking these names; they are deploying them quickly as working sites or branded products. I reviewed 49 .ai domains that NameBio lists as sold on Spaceship through April, and roughly two-thirds are already developed and active.
A notable pattern is the rise of industry- or role-specific AI offerings. Many of the businesses using these .ai names position themselves as “AI for law firms,” “AI for HR,” or other vertical solutions. Yet their brand names typically remain short and abstract, avoiding explicit industry terms—lean, memorable names that can scale beyond a single use case.
