Anthropic's annualized revenue run rate tops $65 billion ahead of expected IPO

Anthropic told investors its annualized revenue run rate surpassed $65 billion at the end of July, a sevenfold jump from roughly $9 billion at the end of last year, as the company moves toward a widely expected initial public offering later this year.

What's new

As TechCrunch reported, "Anthropic's revenue continues to not only grow at an historic pace but also to accelerate. The model maker's annualized revenue run rate — a projection of a full year's revenue based on a recent, shorter period — surpassed $65 billion at the end of July, Bloomberg reported on Monday, up from $47 billion in May and just $9 billion at the end of last year." Annualized run rate is a snapshot projection, not booked annual revenue: it takes a recent period's revenue pace and extrapolates it across a full year, so it moves faster than trailing revenue figures typically do.

The jump follows an already-fast climb: Anthropic reported an annualized run rate of roughly $47 billion in May, meaning the company added close to $18 billion in projected annualized revenue in just two months. Investors reportedly anticipate Anthropic will finish 2026 with actual revenue between $100 billion and $120 billion. For comparison, rival OpenAI's run rate has been reported around $40 billion, putting Anthropic ahead on this particular growth metric even though OpenAI remains larger by other measures like user base.

Context

The disclosure comes as both Anthropic and OpenAI have filed confidential paperwork for public offerings, with Anthropic reportedly eyeing a listing this fall at a valuation that could reach $2 trillion. Anthropic's growth has been driven heavily by enterprise and API demand for its Claude models — including Claude Code and its Managed Agents platform — rather than a ChatGPT-style mass consumer product, a different growth shape than OpenAI's. The figure also lands the same week Anthropic published its second Risk Report and continued rolling out watermarking on Claude-generated content, as the company balances rapid commercial growth with public safety commitments ahead of going public.

Why it matters

A sevenfold increase in annualized revenue run rate in under eight months is an extraordinary growth rate for a company already generating tens of billions in projected revenue — most companies see growth like that decelerate as the base gets larger, not accelerate. If Anthropic's actual 2026 revenue lands anywhere near the $100–120 billion range investors are reportedly expecting, it would cement Anthropic as one of the fastest-growing technology companies in history heading into its public debut, and would materially shape how public markets price both Anthropic's IPO and any subsequent OpenAI listing. It also raises the stakes on Anthropic's forthcoming public financial disclosures, which will let outside analysts scrutinize these investor-relayed figures for the first time.
