Rank = a transparent count of validated relationship edges, never a composite score. Investment figures are declared/announced amounts. OpenAI's $122B includes conditional and vendor-linked components (~$37B immediate cash). Valuations are post-money where reported. Key claims externally validated June-July 2026 (TechCrunch, Bloomberg, CNBC, NYT, Quartz). Relationship years are first-public-announcement years; long-tail partnerships without a public record carry era estimates (flagged yearEstimated).
