Overview
Moody's combines a global credit-ratings franchise with a large risk data and software business. In Q1 2026, Ratings represented about 55% of external revenue and 73% of segment adjusted operating income. The primary moat is Moody's status as a de facto credit-risk standard: ratings are embedded in debt-market convention and regulation, while EU turnover data show a concentrated three-agency market. NRSRO registration alone and company brand claims are not separate moats. Analytics has a smaller, evidence-backed advantage where subscriptions and customer data are embedded in mission-critical risk workflows, including the Intelligent Risk Platform. Competition, private credit, internal models, AI-enabled substitutes and regulatory efforts to reduce ratings reliance are key risks.
