Anthropic's S-1 shows the top-5 customers' share of quarterly revenue fell from 36% in Q1 2026 to 21% in Q3, with all other customers rising from 64% to 79%. Notably, absolute revenue from each top-5 customer still hit all-time highs in Q3 — diversification driven by growth, not churn. No single customer exceeded 10% of revenue for Jan–Sep 2026.
