Method & sources
Each figure carries the **round and date** it is tied to (valuations move very fast: OpenAI $730B in Feb 2026 → $852B in March; Anthropic $380B in Feb → $965B in May). **Confidence** tiers: first-party = the company's own funding announcement; press-confirmed = valuation not disclosed by the company but reported by Reuters/Bloomberg/WSJ/CNBC; press-reported = less certain / anonymous sources. **Rumored-but-not-closed rounds are excluded** (e.g. Mistral's reported €20B round, Perplexity above $20B, Thinking Machines $50B, SSI's Nvidia investment amount).
