Summary
Claude Code ARR and user growth from May 2025 to April 2026
Description
Methodology
Figures are blended from disclosed milestones and interpolation. Months between anchors use smoothed growth curves; early months (May–Oct 2025) assume a typical enterprise SaaS J-curve from near-zero.
ARR Anchors
- Nov 2025 — $1B ARR, reached ~6 months after public launch (Orbilon, SaaStr)
- Jan 2026 — ~$1.2B implied (doubled by Feb per SaaStr/Anthropic)
- Feb 2026 — $2.5B ARR (Anthropic Series G press release, Feb 12 2026)
- Apr 2026 — ~$5.5B implied from Claude Code's ~18–20% share of Anthropic's $30B total ARR (SaaStr, Apr 2026)
ARR uses Anthropic's definition: last month's revenue × 12 (run-rate).
User Estimates
Anthropic does not publish Claude Code-specific MAU. The "Est. developers using" line is modeled from daily install trends (30-day moving average from uncoveralpha.com, Jan 2026), a global base of ~28M professional developers, and survey data showing ~42–58% of developers using Claude Code by early 2026. Post-Feb 2026 install figures are extrapolated.
11-Month Growth
From May 2025 launch through April 2026, ARR grew approximately 110× ($0.05B → $5.5B).
All figures should be treated as directional. Data current as of April 2026.
