MSCI · CIK 0001408198
What MSCI Inc. told the SEC could break it.
MSCI's revenue is concentrated in its largest clients: BlackRock alone was 10.8% of consolidated operating revenue in 2025 — and 18.7% of the Index segment — so a major client's cancellation or reduction would meaningfully hit results. On the input side it depends on third-party suppliers of data, applications and services, including stock-exchange data, and on outside vendors (some of them competitors) to distribute its data, leaving it exposed to their fees, quality and willingness to keep supplying. Regulation touches both ends of its business: sanctions that bar users of its indexes from investing in certain markets or securities can indirectly affect index construction and composition, and the EU's new ESG-ratings regime requires authorization and ESMA supervision for its Sustainability and Climate segment.

In its own words

Customer concentration
- revenue concentrated in largest clients (BlackRock 10.8% consolidated / 18.7% of Index)medium
A material portion of MSCI's revenue is concentrated in its largest clients; BlackRock alone was 10.8% of consolidated operating revenue (18.7% of the Index segment) in 2025, so client cancellations or reductions could materially hurt results.
“A material portion of our revenues is concentrated in some of our largest clients. For the fiscal year ended December 31, 2025, our largest client organization by revenue, BlackRock, accounted for 10.8% of our consolidated operating revenues.”
SEC filing →As of 2026
Supplier concentration
- third-party data suppliers (stock exchanges, Vendor Products) and distribution vendorsmedium
MSCI relies on third-party suppliers of data, applications and services (including stock-exchange data, 'Vendor Products') and on third-party vendors — including some competitors — to distribute its data; fee increases, refusals, or quality issues could raise costs or disrupt operations.
“We rely on third-party suppliers of data, applications and services, including data from stock exchanges and other suppliers (collectively, “Vendor Products”), and depend on the accuracy and quality of Vendor Products and the ability and willingness of such suppliers to deliver, support, enhance and develop new products on a timely and cost-effective basis.”
