Summary

Anthropic closed a $13B Series F at a $183B post-money valuation, led by ICONIQ with co-leaders Fidelity and Lightspeed. Additional investors: Blackstone, Goldman Sachs, Qatar Investment Authority. At announcement: run-rate revenue grew from ~$1B at start of 2025 to $5B+ by August 2025; Claude Code generating $500M+ run-rate since its May 2025 GA; 300,000 business customers; 7x increase in $100K+ accounts. Funds earmarked for enterprise capacity, safety research, and international growth.

Implications

• Capital thread. $183B valuation in September 2025, rising to $380B by February 2026 — Anthropic’s valuation roughly doubled in five months. The Series F → Series G trajectory is the fastest valuation growth of any company in this category.
• Investor profile evolution. ICONIQ (family office/sovereign wealth), Fidelity (public markets), Blackstone (PE), Goldman Sachs (bank), Qatar Investment Authority (sovereign) — this is a fully institutional investor base that signals IPO preparation. VC-heavy rounds don’t have this mix.
• Claude Code at $500M run-rate within 4 months of GA. The $500M Claude Code figure at Series F grows to $2.5B at Series G (February 2026, 9 months later) — 5x in five months. This is the revenue line that drove the valuation step-up.
• 7x growth in $100K+ accounts. Large account growth outpacing overall customer count growth means the revenue concentration is increasing — fewer, larger customers generating more revenue per account. This is the enterprise SaaS maturity pattern.
• Watch: IPO timeline signals; whether Qatar Investment Authority and sovereign wealth participation indicates Middle East/Asia deployment expansion plans; Series G round composition for further institutional signals.
