The companies’ [soaring valuations](https://sherwood.news/tech/anthropic-in-talks-for-funding-at-a-valuation-as-high-as-950-billion-which-would-make-it-bigger-than-openai/) and [annualized recurring revenue](https://sherwood.news/tech/report-anthropic-is-catching-up-to-openai-on-track-for-usd9-billion-annual/) (ARR) have been running neck and neck for months, and The Information now reports that Anthropic is generating an estimated 35% more revenue than OpenAI. According to The Information’s reporting, Anthropic is close to a staggering $45 billion ARR, while OpenAI is at an estimated $33 billion ARR. Last month, Anthropic announced that its [ARR had reached $30 billion](https://sherwood.news/tech/anthropics-revenue-run-rate-just-topped-usd30-billion-thats-ahead-of-openai/) — tripling since the end of 2025. That put it ahead of OpenAI’s $24 billion ARR, which the ChatGPT maker reported at the end of March. Then last week it was reported that OpenAI held a [$1 billion lead](https://sherwood.news/tech/report-openais-q1-revenue-was-5-7-billion-beating-anthropic/) in Q1 revenue over Anthropic. That $45 billion ARR is a whopping 5x the $9 billion Anthropic reported at the end of 2025.
