Anthropic hit B ARR in 16 months. I went looking for where the money is actually coming from.

Short summary

Anthropic's $30B ARR stems primarily from enterprise contracts and coding tool vendors reselling Claude (GitHub Copilot, Cursor, Windsurf), not individual developers. Revenue flows through multiple margin-taking layers—a $0.04 API call becomes a seat fee several multiples higher—but 50-70% gross margins get consumed by model training. The next margin compression will come from wrapper tools facing commoditization pressure.

• •$30B revenue comes from large enterprise contracts and coding tool resellers, not direct consumer use
• •Multiple margin-taking layers mean end users pay 5-10x raw API costs while inference maintains 50-70% gross margin
• •Wrapper tools (GitHub, Cursor, Windsurf) now face margin compression as customers seek cheaper alternatives
