Anthropic Overtakes OpenAI in Revenue, Hitting $30 Billion Run Rate

A remarkable shift has taken place in the competition among major AI companies: Anthropic, developer of the AI assistant Claude, has overtaken OpenAI in annualized revenue. While Anthropic reports a run-rate revenue of over 30 billion US dollars, OpenAI states its own figure at around 24 to 25 billion US dollars per year (2 billion US dollars per month). The decisive difference lies in strategic focus: Anthropic consistently targets the enterprise business, while OpenAI has traditionally aimed at end consumers with ChatGPT.

The figures Anthropic has published are impressive. At the end of 2025, the company's annualized revenue was still around 9 billion US dollars. Since then, that figure has more than tripled. Particularly striking is the growth in the large-customer segment: when Anthropic announced its Series G funding round in February 2026, the company counted over 500 enterprise customers each spending more than 1 million US dollars per year. Today, there are already more than 1,000 such customers -- a doubling in less than two months.

OpenAI is also posting impressive growth figures. As a technology platform, the company reached 10 million and subsequently 100 million users faster than any other company. Within one year of ChatGPT's launch, OpenAI generated revenue of 1 billion US dollars; by the end of 2024, it was already 1 billion US dollars per quarter. Today, monthly revenue stands at 2 billion US dollars. OpenAI claims to be growing its revenue four times faster than the companies that defined the internet and mobile era, including Alphabet and Meta.

The key difference, however, lies in the customer structure. OpenAI's growth is strongly driven by the mass-market product ChatGPT, which is aimed at consumers. Anthropic, by contrast, has focused on enterprise customers and API usage from the very beginning -- that is, on companies that integrate Claude into their own products and processes.

To secure further growth, Anthropic has concluded a far-reaching infrastructure agreement with Google and Broadcom covering several gigawatts of next-generation computing capacity. The new TPU capacities are set to come online incrementally from 2027 onward and will be located predominantly in the United States. This is an extension of the commitment announced in November 2025 to invest 50 billion US dollars in American AI infrastructure.

Anthropic operates its models on a broad hardware base, including AWS Trainium, Google TPUs, and NVIDIA GPUs. Amazon remains the primary cloud provider and training partner. Claude is also the only frontier AI model available on all three major cloud platforms: Amazon Web Services (Bedrock), Google Cloud (Vertex AI), and Microsoft Azure (Foundry).

That Anthropic would overtake OpenAI in revenue was already predicted by Epoch AI back in February 2026, with an estimated timeframe of around mid-2026. Now, however, it has happened even earlier.
