Claude Code Revenue Tops $2.5B Annualized; 4% of GitHub Commits Now AI-Authored

Anthropic's Claude Code hit $2.5B annualized revenue, the fastest-growing developer tool in history. An estimated 4% of GitHub commits are now AI-authored, quadrupling from under 1% a year ago. Growth accelerated after Opus 4.6 launched in February 2026, which stepped up agentic coding capabilities including multi-file autonomous execution from the command line.
