Keying in chat.com will now automatically take you to ChatGPT. The change occurred on Wednesday after OpenAI purchased the domain that was once owned by Dharmesh Shah, the founder and CTO of HubSpot.

Shah reportedly purchased chat.com for $15.5 million in early 2023 but within a few months, he sold the domain without disclosing the buyer’s details but confirmed that it was sold for more than he had originally paid.

“The reason I bought chat.com is simple: I think Chat-based UX (#ChatUX) is the next big thing in software. Communicating with computers/software through a natural language interface is much more intuitive. This is made possible by Generative AI,” Shah wrote in a LinkedIn post announcing the purchase, which chat.com briefly redirected to before he resold it.

Chat.com is one of the most prestigious and older domains on the web, having been registered in September 1996.

Shah confirmed in a post on X that OpenAI purchased the domain from him and implied that the startup paid him in shares instead of cash.

The dropping of “GPT” from the domain name stacks up with OpenAI’s recent rebranding efforts. In September, the company announced a new series of reasoning models starting with “o1”, which marks “the first step of newer, more sane names” to better communicate the company’s work.

Hanging on to old domain names has been a business for a long time. A few months ago, AI startup Friend spent $1.8 million on the domain friend.com after raising $2.5 million in funding.
