|---|---|---|---|
| Q1 2024 | 18M | 0.4M | — |

Claude's growth accelerated meaningfully through 2025 as Anthropic expanded availability outside the United States, launched Claude Code, and shipped the Sonnet 4.6 and Opus 4.7 model families. The 220 million monthly active user figure trails ChatGPT (540 million) and Gemini (410 million), but Claude's usage profile is heavier, longer sessions, more enterprise deployment, and higher revenue per user.
Claude API Adoption
The Claude API is Anthropic's primary commercial surface and is the most consequential channel for the broader AI ecosystem. API customers include AI startups (Cursor, Windsurf, Replit, Perplexity), enterprise AI platforms, and tens of thousands of internal corporate AI applications.

| API customer organisations | 36,000 | 87,000 | +142% |
| Average monthly tokens per organisation | 1.2B | 3.4B | +183% |
| API revenue contribution | 52% | 58% | +6pp |
| Percent of API revenue from enterprise commits | 39% | 54% | +15pp |
Claude Code Adoption
Claude Code is Anthropic's coding assistant, distributed as a CLI for developers and an SDK for engineering teams. Since launch, adoption has grown rapidly inside developer-heavy organisations. As of Q1 2026, Claude Code has approximately 4.2 million weekly active developer users, deployments at over 1,400 enterprise engineering organisations, and a measured productivity lift of 27 to 41 percent on common engineering tasks across user studies. Claude Code accounts for an estimated 18 percent of Claude API token consumption.
Enterprise Claude Adoption
Enterprise mix is the defining characteristic of Anthropic's business. Claude Enterprise (consumer-style enterprise tier) and Claude Team (small-team subscription) plus large API commits collectively generate approximately 64 percent of Anthropic revenue, the highest enterprise mix of any major AI provider. The top deployment categories are software engineering, regulated industries (financial services, healthcare, legal), and customer support. Average enterprise contract values range from 100,000 to 8 million dollars annually, with Fortune 500 deployments commonly exceeding 1 million dollars.
