Businesses continue to buy aftermarket .ai domains and put them to use.

The impact of the artificial intelligence boom on the domain name industry cannot be overstated. Companies are buying .ai domains, .com domains for their AI businesses, or domains for sites they built with AI.
On the .ai domains front, there are over one million registered .ai domains. So far, Spaceship alone has accounted for over $3 million in aftermarket .ai domain sales this year, and that’s just the ones reported on NameBio.
Companies aren’t just sitting on these domains. They’re quickly putting them to use for their businesses.
I reviewed 49 .ai domains that NameBio shows as sold on Spaceship through April. About two-thirds are already developed.
One thing you’ll notice is that many of these companies are industry or role-specific AI businesses. They are basically “AI for law firms” or “AI for human resources”. And yet…none of their brand names allude to these industries or roles.
Here are 33 .ai domains sold this year that are being used by businesses.
