OpenAI has acquired the chat.com domain name, likely for well over $10 million. OpenAI CEO Sam Altman posted a one-word tweet this morning, simply stating, “chat.com.” Domain Name Wire reports: The chat.com domain name has changed hands for the third time in two years. HubSpot founder Dharmesh Shah kicked off the buying last year, plunking down over $15.5 million for the domain name. He turned around and sold the domain shortly thereafter for a profit.
