Four distinct concentration patterns identified: (1) Declining S1 — ERP, Cloud, Productivity — where market TAM grew faster than the leader, producing CR3 stability but lower S1. (2) Rising S1 — CRM (Salesforce), ITSM (ServiceNow), Payments (Stripe) — where cloud-native players displaced on-prem incumbents. (3) Stable oligopoly — CAD/PLM held ~56% CR3 for 15 years. (4) Reconsolidating after disruption — Data & Analytics went 30% → 18% → 29% as Snowflake/Databricks re-concentrated after the Hadoop era.
