Anthropic Hits $30B Revenue Run Rate, Pulls Ahead of OpenAI After 'Crazy' 80x Year

Anthropic told investors this week that its annualized revenue run rate hit $30 billion as of early April 2026, a roughly 3x jump from the $9 billion it reported at the end of 2025 and a figure that, at face value, puts it ahead of OpenAI for the first time. OpenAI's most recently disclosed run rate, from March, was $24 billion. The numbers landed alongside a fresh disclosure that more than 1,000 enterprise customers now spend over $1 million a year with Anthropic, double the count from February.

CEO Dario Amodei described the trajectory in unusually candid terms, telling staff that the company had planned for 10x growth this year and ended up tracking closer to 80x — a pace he characterized as "crazy" and "too hard to handle." The surge tracks the launch of Claude Mythos, which has become the default model for a growing roster of Fortune 500 deployments, and an aggressive rollout of managed agents into law, finance, and software engineering workflows.

The headline comparison comes with an asterisk worth flagging. Anthropic books the full amount its cloud customers pay through partners like Google Cloud and AWS as revenue, then deducts the providers' cut as cost of goods sold. OpenAI, by contrast, recognizes only the net it actually receives after Microsoft and other partners take their share. Reporting suggests Anthropic could pay out roughly $1.9 billion to cloud partners this year and as much as $6.4 billion in 2027, which means the real gap with OpenAI is narrower than the topline implies — though the growth slope is what investors are paying for.

Underneath the revenue figure is a compute-supply story. Anthropic is leaning on an expanded partnership with Google and Broadcom that locks in 3.5 gigawatts of AI capacity starting in 2027, plus the previously announced $200 billion TPU commitment and exploratory talks with chip startups. The pitch to enterprise buyers — frontier models trained for far less capex than rivals, paired with a deep agent stack — is for now translating into the kind of growth curve that even seasoned SaaS analysts say has no precedent in public-software history.

Whether the trajectory holds is the open question. Eight of the Fortune 10 are now Claude customers, but consumer revenue remains a rounding error compared to OpenAI's ChatGPT business, and the company has yet to disclose gross margins net of cloud pass-through. The next test arrives with Anthropic's expected $50 billion fundraise at a $900 billion valuation — likely the last private round before an IPO that would force it to reconcile the two ways the industry has learned to count its money.
