Anthropic Financials: September 2026 Update

This update is a roundup of same-day reporting from the linked sources below, with editorial context from the CPJ Stock Desk.

Anthropic enters September with a revenue run-rate of $65 billion (Sacra, July 31) and an IPO filing that Bloomberg reports is expected within weeks, potentially putting the company in front of public investors before year-end.

Key points

Revenue run-rate reached $65B as of July 31, up from $47B in May, per Sacra. That is roughly 38% growth in under three months.
The $965B valuation set by the May 2026 Series H is unchanged. No new round has closed.
Anthropic signed $80B in compute commitments in August alone: a $45B deal with Nscale (460 megawatts of GPU capacity) and a $35B cloud deal with Nvidia-backed Lambda.
Bloomberg reported on August 31 that an IPO filing is coming in the next few weeks, with some market observers citing a potential public valuation of $1 trillion to $2 trillion.
Legal risk grew: Sony Music and Warner filed suit on August 29 alleging broad copyright infringement in Anthropic’s training data.

How does the revenue growth stack up?

At $65B annualised, Anthropic has grown its run-rate more than seven-fold since the end of 2025 (estimated $9B then). The pace is notable even by AI-sector standards. OpenAI, for comparison, sits at a $40B run-rate as of July 31 (Sacra), meaning Anthropic now leads its closest private-market peer on revenue by a wide margin, while carrying a valuation premium of roughly $113B ($965B vs. $852B).

The revenue base is still heavily enterprise-weighted. As of May, 80% of revenue came from business customers, with over 1,000 accounts spending seven figures annually and eight Fortune 10 companies in the customer base.

What is driving the compute commitment spree?

The Nscale and Lambda deals, totalling $80B, reflect both scale and strategic urgency. Locking in GPU capacity ahead of a public offering signals confidence in demand, but it also creates substantial fixed obligations. The Lambda deal carries Nvidia backing, deepening the chip giant’s financing role in the AI supply chain. Anthropic also launched a standard in late August enabling Claude to interface with robots and laboratory hardware, broadening the addressable market beyond software.

A federal court ruling on August 28 cleared another avenue for growth: a judge found the government’s supply-chain-risk designation unlawful and ordered the ban on Anthropic’s AI for federal agencies lifted, reopening the public-sector market.

On the partnership side, Salesforce expanded its collaboration to build a reasoning-capable AI interface inside its platform, adding another large enterprise distribution channel.

IPO watch: what does the filing window look like?

Bloomberg’s August 31 report places the filing within weeks. The Information reported separately that Anthropic is considering letting existing shareholders sell in the IPO while imposing longer-than-standard lockups and structured employee trading windows, a structure that draws on late-stage private-company playbooks used by SpaceX.

Anthropic also told investors it sees more than $30 trillion in potential revenue, per the Wall Street Journal, a figure aimed at framing the scale of the opportunity for prospective public-market buyers rather than serving as a near-term forecast.

The backdrop for the offering is mixed. The four most relevant public benchmarks are all down on the day: Amazon ($254.78, -1.92%), Google ($335.63, -1.10%), Microsoft ($501.00, -1.24%), and Nvidia ($219.54, -0.56%). A broad technology selloff in the weeks before an IPO roadshow is not ideal, but the filing timeline suggests Anthropic is targeting a post-Labor Day window regardless.

One overhang worth watching: the Sony Music and Warner lawsuit, filed August 29, alleges a broad campaign of intellectual property theft in training data. IP litigation has not derailed AI company financings to date, but the suit adds litigation-risk disclosure to any prospectus.
