“Never seen such growth!” Claude Code drives explosive increase, Anthropic’s annualized revenue doubles in two months to $44 billion

```

Anthropic is rewriting the growth records of the tech industry at an unprecedented pace.

According to the latest report from semiconductor and AI infrastructure research firm Semi Analysis, Anthropic’s annual run rate (ARR) has surpassed $44 billion. This figure is nearly five times higher than its approximately $9 billion at the end of 2025, meaning the company added about $96 million in ARR every day over just a few months. An investor who reviewed Anthropic’s data said, "We have studied over 200 public software company IPOs, and have never seen growth like this before."

The core driving force of this growth surge comes from exploding enterprise demand, as well as the strong performance of its programming agent product, Claude Code. Meanwhile, the Semi Analysis report shows that gross margins for Anthropic’s inference infrastructure have jumped from 38% a year ago to over 70%—showing the company is not only expanding rapidly, but also growing more efficiently.

Buoyed by this, Anthropic is reportedly advancing a $50 billion funding round at a valuation exceeding $1 trillion, with Goldman Sachs, JP Morgan, and Morgan Stanley already in early-stage talks.

Growth curve: Unprecedented in software history

Anthropic’s ARR trajectory has almost no historical reference point.

According to CEO Dario Amodei, the company has achieved approximately 10x revenue growth each year since its first earnings:

2022 ARR was about $10 million, 2023 about $100 million, December 2024 about $1 billion, September 2025 about $7 billion, December 2025 about $9 billion, February 2026 about $14 billion, March 2026 about $19 billion, April 2026 about $30 billion, and as of May 2026, over $44 billion.

Notably, the most dramatic acceleration occurred after February 2026—in just three months, ARR surged from $14 billion to $44 billion.

Claude Code is the key variable in this recent surge. This programming agent was publicly launched in May 2025. By February 2026, its annualized revenue had reached $2.5 billion and continued to climb.

Since January 2026, Claude Code’s weekly active users have doubled. Some analyses estimate about 4% of global GitHub public commits are now generated by or involve Claude Code, with enterprise usage accounting for more than half its revenues.

The strategic value of Claude Code lies in bridging user adoption from individuals to enterprise procurement.

Individual developers first use Claude Code for daily programming tasks; the tool then moves into team codebases and eventually triggers company-level unified procurement, permissions configuration, and security compliance access. Personal usage habits thus transition to organizational processes, forming a natural penetration path from To C to To B.

For comparison, AWS took 13 years to reach $35 billion in annual revenue. Salesforce, founded in 1999, only passed $20 billion in 2021, while ServiceNow took about 20 years to exceed $9 billion. Anthropic covered in one year what many software companies took one or two decades to achieve.

Enterprise clients: From trials to embedded infrastructure

Anthropic’s major growth driver comes from enterprises, not consumer subscriptions.

The Semi Analysis report shows that 8 out of the Fortune 10 are now Claude’s clients; the number of enterprise customers spending over $1 million annually has grown from just over a dozen two years ago to more than a thousand; customers spending over $100,000 per year grew sevenfold in the past year.

In terms of market share, Anthropic’s share of enterprise AI spending, relative to OpenAI, rose from about 10% at the start of 2025 to over 65% by February 2026—a reversal at an almost unprecedented speed in the industry.

The underlying structural change here is enterprises are now buying Claude not for “innovation projects” but as “core workflow.” Legal, finance, consulting, and customer service departments are embedding Claude into stable process chains, with procurement methods shifting from seat-based licenses to consumption-based billing. Semi Analysis points out companies are not experimenting with Claude, but embedding it into critical business flows, signing long-term contracts, and ramping up usage.

Distribution advantages should not be overlooked. Claude is the only leading AI model simultaneously available on AWS Bedrock, Google Cloud Vertex AI, and Microsoft Azure Foundry—the breadth of coverage unmatched by rivals so far.

Gross margin leap: The key signal of commercial quality

The most significant data in the Semi Analysis report might be the sharp gross margin improvement. Inference infrastructure gross margin climbed from 38% to over 70%, elevating the Anthropic story from “speed of growth” to “commercial quality.”

High-growth AI companies have always faced a core doubt: Is revenue being bought at a loss through compute costs?

Analysis suggests the significant improvement in gross margin means Anthropic’s unit economics are improving. This could result from increased model inference efficiency, caching and routing optimization, better hardware utilization, and more stable loads via enterprise contracts.

This is also the core logic for investors willing to grant a valuation of about 20 times ARR. If inference margins above 70% are sustained, Anthropic will no longer be merely a “money-burning model company,” but more akin to an AI infrastructure firm with software-level gross margins. By contrast, Anthropic expects to become profitable by 2028—earlier than competitor OpenAI’s post-2030 expectation.

IPO prospects: The real test beyond the speedometer

Anthropic is reportedly considering going public as early as the end of 2026, aiming to realize $26 billion in actual annual revenue by then. If $44 billion ARR is maintained, that target does not look aggressive.

However, ARR is a speedometer, not a finish line. It reflects current growth momentum but does not guarantee full-year performance. Enterprise AI spending still needs to pass the test of budget cycles: Can high-frequency usage in trial phases become long-term contracts? Will developer enthusiasm translate into organizational renewals? Can Claude Code’s efficiency gains be accepted by large enterprises in audit, security, and compliance? All of these will determine the quality of Anthropic’s revenue.

Competitive pressures also persist. OpenAI has the strongest consumer mindshare and developer ecosystem; Google has cloud, Workspace, and TPU synergy; Microsoft controls mass enterprise distribution; Meta keeps slashing industry prices with open-source models.

Semi Analysis asserts that current enterprise demand for Claude is structural rather than cyclical. If the $44 billion ARR can be sustained, Anthropic will not only challenge OpenAI’s valuation, but also rewrite the industry’s imagination for an AI company’s growth ceiling.
