Anthropic's S-1 shows customers spending $100K+ annually grew from 20 (Dec 2023) to 200 (Dec 2024), 1,500 (Dec 2025), and over 11,900 (Sep 2026) — roughly 8x in a year. Yet in Q3 2026, Fortune 500 customers still spend on average less than 0.1% of their total costs on Anthropic, implying huge headroom for enterprise penetration.
