OpenAI usage: common questions
How many companies use OpenAI?
9,483 companies have verified their domain with OpenAI, as of 3 November 2026. This counts companies we can tie to a LinkedIn company page, so it is a floor, not a market total.
Which well-known companies use OpenAI?
By LinkedIn following, the largest include The Wall Street Journal, Boston Consulting Group (BCG), Bain & Company, Zoho and Thomson Reuters. The table above lists more, with the evidence for each.
What industries use OpenAI the most?
Software Development (831 companies), IT Services and IT Consulting (761) and Technology, Information and Internet (463) lead, out of 9,467 companies with a known industry.
Which countries have the most OpenAI users?
United States (42%), India (19%) and United Kingdom (5.3%). We see OpenAI at companies headquartered in 114 countries.
What tools do OpenAI users also use?
Compared with the average company in our data, OpenAI users are most over-represented on Cursor (10.9×), Notion (9.7×), Claude (5.4×). The multiplier is how much more likely they are than average to run that tool too.
How do you know a company uses OpenAI?
OpenAI asks companies to publish a DNS TXT record ("openai-domain-verification=…") to prove they own their domain — an admin step taken when setting up a company workspace or account. We read public DNS records for company domains and count the ones carrying that record. A company is only counted when we can tie the domain or app to its LinkedIn company page, and shared domains (link shorteners, site builders) are excluded, so a domain scan of bit.ly never counts as evidence about a brand that links to it.
