The .ai ccTLD registry sold over 50,000 domain names in just over a quarter, according to the registry.
Its recently updated web site says its total domains under management as of September 23 was 306,861, compared to 248,609 on June 14.
That represents a growth acceleration from its last update, which saw it register over 100,000 domains in a year.
The domain is of course popular due to the rise of artificial intelligence technologies and the popularity of chatbots such as ChatGPT.
The registry says its renewal rate in over 90% — very high for a TLD — but it expects that to decline due to its rapid growth.
The registry is managed by the Government of Anguilla, a British Overseas Territory in the Caribbean.
