Ask anyone on the street to name an AI company, and you will almost certainly hear the same answer: OpenAI, the maker of ChatGPT. Ask them to name a second one, and most will struggle. ChatGPT is the AI your aunt uses to write birthday card messages and your teenager uses to cheat on history homework. It has 900 million weekly users. It is, by any reasonable measure, the most famous software product on earth.
So here is something genuinely strange. According to new data published this week by Ramp — a finance platform that quietly watches how more than 50,000 American companies spend their money — there is now a different AI company sitting at the top of corporate invoices. It is called Anthropic. Its product is called Claude. And in April, 34.4% of the businesses Ramp tracks were paying for it, compared with 32.3% paying for ChatGPT.
That gap is small. The story behind it is not. For roughly two years, OpenAI has been winning the headlines, the magazine covers, and the dinner table conversations. Anthropic has been quietly winning the invoices. This week, the gap between fame and adoption finally got wide enough to see with the naked eye — and the way both companies reacted tells you everything about which fight actually matters.
