Anthropic told investors its annualized revenue run rate reached $65 billion at the end of July, up from more than $47 billion in May and $14 billion in February.
That is extraordinary acceleration for a company already operating at enormous scale. The reported pace has increased about 4.6 times since February, including a 38% jump in roughly two months.
But the figure needs one important translation: Anthropic did not collect $65 billion over the past year. A run rate projects a recent period of sales across a full year. At $65 billion annually, Anthropic was generating revenue at a pace of about $5.4 billion a month by the end of July.
The acceleration is showing up in actual sales
The run rate is not simply a dramatic way to present Anthropic’s quarterly total. The company recorded preliminary second-quarter revenue of $11.5 billion, or about $3.8 billion a month on average. Its end-July pace was roughly 41% higher than that monthly average.
That suggests demand was still accelerating after the quarter closed.
The clearest explanation is Anthropic’s focus on businesses, particularly software development. By February, Claude Code alone had exceeded a $2.5 billion annualized revenue pace. Enterprise customers supplied more than half of the product’s revenue, while more than 500 customers were each spending at least $1 million a year across Anthropic’s products.
Independent expense data points in the same direction. In June, 42.4% of businesses in Ramp’s sample paid Anthropic, compared with 39.5% paying OpenAI. The sample covers Ramp customers rather than the entire market, so it is evidence of Anthropic’s strength among businesses, not a definitive industry ranking.
Growth is becoming an infrastructure problem
Selling more AI services means buying access to far more computing power. Anthropic has committed more than $100 billion over ten years to Amazon Web Services technologies for as much as five gigawatts of capacity. It has also announced plans for another five gigawatts with Google and Broadcom, along with GPU access from SpaceX.
Five gigawatts is power-plant scale. The commitments show the physical consequence of Anthropic’s sales growth: serving all those Claude requests requires data centers, chips and electricity on a vast and expensive schedule. Anthropic has acknowledged that demand was already straining Claude’s reliability and performance.
That capital appetite helps explain the company’s recent $65 billion funding round at a $965 billion post-money valuation. Anthropic has also confidentially submitted draft paperwork for an initial public offering, although no timing, price or share count has been set.
The OpenAI comparison remains messy
On the latest reported figures, Anthropic’s $65 billion run rate stands above OpenAI’s reported $40 billion pace. But that does not establish a clean, audited lead.
The companies may account differently for revenue sold through cloud partners. Earlier reporting found that Anthropic included the gross value of some partner token sales while OpenAI counted only its share, a difference that could distort an annualized comparison by as much as $8 billion.
The firmer conclusion is simpler: Anthropic has turned its foothold with developers and large companies into one of the fastest revenue expansions in technology. Its next constraint may be less about finding customers than building enough infrastructure to serve them.
