Anthropic Hit a $47 Billion Run Rate as Pentagon Talks Reached Court

Anthropic’s run-rate revenue crossed $47 billion in May, making the roughly $19 billion estimate from early March a historical snapshot rather than a current measure. Anthropic’s May 28 financing announcement placed the figure above $47 billion earlier that month, up from approximately $9 billion at the end of 2025.

The company has passed OpenAI’s latest available public benchmark, but the figures do not establish which business is larger today. A Reuters report on OpenAI’s February figure put annualized revenue above $25 billion, while Lawfare’s July 30 hearing record shows that Anthropic’s Pentagon negotiations had developed into litigation awaiting decisions in two federal proceedings.

Anthropic’s March revenue snapshot is obsolete

Anthropic’s May disclosure more than doubled the run-rate figure associated with the company in early March. That acceleration is the most substantial update to the original comparison: it changes Anthropic’s scale relative to the older OpenAI benchmark and renders projections based on the March pace unreliable.

The same May announcement paired the revenue disclosure with a $65 billion Series H financing at a $965 billion post-money valuation. It also identified agreements with Amazon, Google, Broadcom and SpaceX as part of an expansion in computing capacity, connecting rising Claude adoption with the costly infrastructure required to serve it.

Those facts support a limited conclusion: Anthropic was selling AI services at a much faster annualized pace and raising capital to expand capacity. They do not disclose recognized revenue for a completed fiscal year, the duration of customer commitments, customer concentration, gross margin or the cost of supplying additional Claude usage.

The OpenAI comparison has a timing problem

OpenAI’s public benchmark covers the end of February, whereas Anthropic’s larger figure covers May. The two observations are separated by several months, and they also have different provenance: Anthropic published its own number, while the OpenAI figure was attributed to a person familiar with the company’s finances and was not independently verified by Reuters.

It is therefore accurate to say that Anthropic crossed a higher disclosed threshold at a later date. It is not accurate to present the two numbers as proof that Anthropic currently leads OpenAI, because the February observation does not reveal OpenAI’s pace in May or its position in August.

A defensible head-to-head ranking would require figures covering the same period and calculated on comparable terms. Without them, the numbers show Anthropic’s rapid acceleration and the age of OpenAI’s available benchmark—not a settled change in market leadership.

Run-rate revenue is not earnings

The headline figures describe annualized revenue run rates, not earnings, profit or sales already collected over a full year. A run rate projects a recent revenue pace across 12 months, giving a fast-growing private company a current indicator without waiting for annual accounts.

At a $47 billion annualized pace, a simple division implies an average of about $3.92 billion per month. That calculation illustrates the scale of the projection; it does not mean Anthropic earned $47 billion in profit or booked that amount during the first five months of the year.

Run rates can move sharply when usage changes or major contracts begin. They also omit the expenses that determine profitability, including model training, inference, data-center capacity, staffing and customer acquisition.

Calling the increase an earnings surge therefore blurs an important financial distinction. Revenue measures sales before expenses, while earnings normally refers to profit after relevant costs. Neither company’s annualized revenue benchmark demonstrates that it is profitable.

The Pentagon disagreement is now a procurement and legal risk

The dispute began with Anthropic’s refusal to permit its frontier AI products to be used for lethal autonomous weapons or mass surveillance of the US population. The Defense Department subsequently designated Anthropic as a supply-chain risk, prompting challenges under two different statutes.

In the district-court case, Anthropic argues that the designation punished protected speech and violated due-process and administrative-law requirements. The government maintains that national-security concerns and doubts about undisclosed model guardrails justified its treatment of the company.

A judge granted Anthropic preliminary relief in March. At the July merits hearing, the parties argued cross-motions for summary judgment, with Anthropic seeking permanent relief and the government defending the designation; the judge did not resolve the case from the bench. A related statutory challenge remained pending in the D.C. Circuit.

The financial consequence is uncertainty rather than a demonstrated loss of revenue. Anthropic can continue expanding in commercial markets while facing unresolved questions about defense deployments, federal procurement relationships and the eventual scope of any judicial remedy.

What the updated figures establish—and what they do not

The strongest current evidence is that Anthropic’s annualized sales pace advanced far beyond its early-March level and exceeded OpenAI’s older February benchmark. It also establishes that the Pentagon negotiations did not end in a commercial compromise and instead became an active legal dispute.

The evidence does not establish audited annual revenue, profitability or a current winner between the companies. Those judgments would require aligned reporting periods plus recognized revenue, margins, cash flow and compute obligations—information that the headline run rates do not provide.

Anthropic’s May disclosure is consequently the fresher signal of commercial momentum, not a complete financial statement or a definitive competitive ranking. Its simultaneous court fight also shows that rapid private-sector adoption and restricted government access can develop along separate tracks.
