Anthropic’s revenue run rate just topped $30 billion — that's ahead of OpenAI, depending on how you count
The Claude maker's revenue run rate has tripled in three months, as Dario Amodei's firm takes the software world by storm.
Anthropic said Monday that its annual revenue run rate has topped $30 billion, more than tripling from the ~$9 billion reported at the end of 2025. That places the Claude-maker ahead of OpenAI, at least on paper, which disclosed roughly $24 billion in ARR at the end of March — a remarkable leapfrogging that would have seemed unthinkable just six months ago.
The jump came alongside the announcement of an expanded partnership with Google and Broadcom, which will give Anthropic access to 3.5 gigawatts of AI compute capacity starting in 2027 to help meet surging demand for its Claude products. The company's latest model, Mythos, is already turning heads.
Over 1,000 enterprise customers are now spending over $1 million annually, more than double the ~500 in February.
Still, as remarkable as Anthropic’s near-vertical growth looks, the Claude maker may not have actually surged past its rival in the AI revenue race, since the comparison isn’t perfectly apples-to-apples.
Both OpenAI and Anthropic sell their AI models through cloud partners such as AWS, Google Cloud, and Microsoft Azure, which take a slice of revenues generated through their platforms. But the two account for those sales differently. According to The Information, Anthropic records the full amount a cloud customer pays as revenue, later counting the partners’ cut as an expense. OpenAI, by contrast, records what it actually receives after the cloud provider takes its share — at least in the case of Azure, its primary cloud partner.
In fact, The Information estimates Anthropic could pay roughly $1.9 billion to cloud providers this year and as much as $6.4 billion in 2027 based on the startup's most optimistic forecasts, meaning the revenue gap with OpenAI could be narrower than it appears.
Beyond the revenue race, both AI startups are burning cash at historic rates, with the ChatGPT maker expecting to burn through a staggering $218 billion between 2026 and 2029 — about 23x what Tesla burned during its most cash-intensive years, and roughly equivalent to the GDP of Ukraine.
