How Index Providers Make Money

Direct answer: Index providers construct and maintain market benchmarks and earn revenue by licensing those indexes to asset managers, exchanges, banks, and other financial institutions. The licensing fee is typically a fraction of a basis point on AUM in linked products, which on trillions of dollars in assets generates substantial annual revenue.

The Licensing Model

An index provider's core product is a rules-based set of criteria that defines which securities belong in a benchmark and in what proportions. The S&P 500 defines which 500 US large-cap stocks qualify, the weights assigned to each, and when changes are made. The MSCI World Index does the same for developed market equities globally.

The index itself has no direct monetary value in isolation. Its value comes from the fact that asset managers, institutional investors, and financial institutions want to create products that track or reference it. An ETF tracking the S&P 500 must pay S&P Dow Jones Indices for the right to market its product as an S&P 500 tracker. An exchange listing a futures contract on the MSCI Emerging Markets Index must pay MSCI for the right to use that index in a listed derivatives product.

That payment is the licensing fee. It is typically expressed as a few tenths of a basis point (a basis point is 0.01% of AUM) charged annually on the assets in linked products. At 0.03% on $500 billion in linked ETF assets, that is $150 million per year from a single index family. Apply that logic across dozens of popular indexes tracking trillions in assets, and the revenue is substantial.

Major Index Providers and Their Segments

The index market is highly concentrated. A small number of providers control the most widely tracked benchmarks.

S&P Dow Jones Indices is a majority-owned subsidiary of S&P Global. It operates the S&P 500, which is arguably the most tracked single index in the world, plus the broader S&P family of US, global, sector, and factor indexes. It also owns the Dow Jones Industrial Average, one of the most recognizable financial names globally. Learn more: How S&P Dow Jones Indices Makes Money.

MSCI is a standalone publicly traded company whose indexes dominate international equity benchmarking. The MSCI World, MSCI Emerging Markets, and MSCI ACWI indexes are the standard references for developed and emerging market equity allocations used by institutional investors globally. MSCI also has analytics and ESG businesses. Learn more: How MSCI Makes Money.

FTSE Russell is owned by London Stock Exchange Group. The Russell 2000 is the dominant US small-cap benchmark; the FTSE 100 is the principal UK large-cap index. The combined FTSE Russell business has broad coverage across US, international, fixed income, and factor indexes.

Bloomberg Index Services maintains the Bloomberg Aggregate Bond Index (the Agg), which is the dominant investment-grade US bond benchmark, and a large family of fixed income, commodity, and multi-asset indexes. Bloomberg licenses these across ETFs, mutual funds, and structured products worldwide.

Data Licensing Alongside Index Licensing

Index providers generate a second significant revenue stream from data subscriptions. Institutional investors, asset managers, risk systems, and analytical platforms need access to index constituent lists, historical data, methodology documents, and calculated index levels.

This data is valuable independently of whether a client is creating an index-linked product. A pension fund comparing its portfolio against the S&P 500 needs access to the index data; a risk management system needs historical index return series; a portfolio analytics platform needs constituent-level data. Index providers charge subscription fees for access to these data products.

Data licensing revenue tends to be more stable than AUM-linked licensing revenue because it is not directly sensitive to market levels. A 30% bear market reduces AUM-linked fee revenue proportionally but does not reduce the number of institutions paying for index data subscriptions. This makes data an important revenue stabilizer.

Derivatives Licensing

Derivatives exchanges pay licensing fees to use index names in listed futures and options contracts. The CME Group pays S&P Dow Jones Indices for the right to list S&P 500 futures and options, some of the most actively traded derivatives contracts in the world. MSCI licenses exchanges globally to list futures on its country and regional indexes.

Derivatives licensing revenue is typically structured as a fee per contract traded rather than a percentage of notional AUM. High trading volumes in listed index derivatives can generate meaningful revenue for index providers. It also reinforces the indexes' brand and utility: an index with liquid futures and options is more attractive as a benchmark because it can be hedged efficiently.

Custom Index Business

Major index providers offer custom index construction for institutional clients who need a bespoke benchmark tailored to their specific investment strategy, liability profile, or mandate constraints. A sovereign wealth fund might need a custom index excluding certain sectors. A pension fund might want a custom benchmark incorporating both fixed income and equity in specific proportions. An insurance company might need an index reflecting its specific liability duration requirements.

Custom index work typically involves a setup fee for designing and implementing the index methodology, plus ongoing annual licensing fees to maintain the index. Because the client cannot simply use a competitor's off-the-shelf product, switching costs are high once a custom index is embedded in a fund or mandate structure. Custom indexes also generate data licensing revenue from reporting and analytics around the bespoke benchmark.

Why Index Providing Is a High-Margin Business

Once an index is established and widely tracked, maintaining it requires modest ongoing costs relative to revenue. The methodology is documented; the index committee meets on a scheduled basis; reconstitution is systematic and rules-based. Adding one more ETF that tracks the index costs the provider close to nothing in marginal effort, while the AUM in that ETF generates continuous licensing revenue.

The business also benefits from network effects and switching costs. The S&P 500 is the standard US large-cap benchmark because virtually every institutional investor, performance analytics system, and financial publication tracks it. The fact that millions of investors hold S&P 500 index funds means any new ETF sponsor is almost compelled to license the S&P 500 to offer a competitive product. Switching to a competing index would confuse investors who expect "the S&P 500 fund" to track the S&P 500.

This combination of low marginal cost, recurring AUM-linked fees, and high switching costs produces operating margins in the index licensing business that are well above most of financial services.
