MSCI Inc.

MSCI Inc. is an American financial data and analytics company that provides investment decision-support tools — indices, portfolio risk models, ESG ratings, and private-asset data — to institutional investors globally, generating $3.13 billion in revenue in fiscal 2025. The company's benchmarks underpin roughly $21 trillion in assets under management, and its equity indices alone anchor $7.4 trillion in indexed products, making MSCI the dominant standard-setter for international equity portfolios and a growing force in fixed income, private markets, and sustainability measurement.

This is a story about a business that has turned indispensability into a compounding machine. For two decades, MSCI has ridden three mutually reinforcing tailwinds — the shift from active to passive, the globalisation of portfolios, and the proliferation of data in the investment process — while steadily layering new revenue streams on top of its original index franchise. The operating economics are extraordinary: 82% gross margins, 62% EBITDA margins, and a subscription-heavy revenue base with retention rates above 94%. The capital-return story is equally stark: the company has repurchased nearly 40% of its shares over the last decade, funding the program with debt that now stands at $6.3 billion against negative tangible equity.

The file turns on a single question: whether MSCI's data and distribution moat widens fast enough to justify a 35x earnings multiple in a world where AI is simultaneously expanding the addressable market for index-style content and lowering the cost of building competing products.
