New research shows how index providers already use AI to enhance data quality and product testing, while transparent methodologies, human accountability and strong governance remain the foundation of index construction

Several index providers are already using artificial intelligence (AI) to research, maintain and test financial indexes – and AI agents may make indexes easier for investors to find and compare, according to a new report from the Index Industry Association (IIA), an education and advocacy organization representing global independent index providers.

The research, “AI and Financial Indexes: Innovation, Governance, and Trust,” finds that the features that have long made indexes trustworthy, including published methodologies, rules-based construction and human accountability, also position the industry to adopt AI responsibly.

AI use is past the experimental stage, with several IIA members reporting that they have used machine learning, natural language processing, and generative tools in data and research operations for a decade or more. It explores how some index providers are applying AI across the index lifecycle; how AI agents may change the way investors, advisers and researchers discover, compare and interact with index information; and the governance considerations that grow in importance as AI’s role expands.

“Artificial intelligence is becoming an increasingly important tool across the financial industry, and index providers are finding ways to use these capabilities to make the processes behind indexes more efficient and scalable,” said Kirsten Wegner, IIA CEO. “But the adoption of AI does not change what makes an index trusted. Transparent methodologies, fit-for-purpose validation, robust governance and human accountability remain fundamental. The opportunity is to apply AI in ways that strengthen these principles while supporting continued innovation across the index industry.”

Key Takeaways:

• AI Insights Are Actionable for Index Providers: Several members report using AI in data and research operations for a decade or more, supporting anomaly detection, reconciliation and back-testing. Flagged data points are typically reviewed before any action is taken.

• Transparency Helps AI Agents Represent Indexes Accurately: IIA members administer over three million indexes. Because methodologies are published and indexes follow set rules, AI agents can help users with discoverability (finding indexes based on what they want to measure), comparability (explaining in plain language how similar indexes differ) and composability (analyzing how indexes may work together or be combined for different objectives).

• Human Accountability Anchors Trust: An index remains a measure of a market, not an investment product or recommendation. Index methodology decisions remain under human oversight, supported by explainability, data governance, operational resilience and third-party risk oversight.

This content is part of the IIA’s ongoing mission to educate and engage the broader public about the essential role of indexes across the global financial landscape. Index providers build tools for trust and transparency, and the paper considers how AI can support that work.

About the Index Industry Association

Many of the leading independent index providers in the world are members of the IIA, including Bloomberg Indices, Cboe Global Indices, China Bond Pricing Co. Ltd., China Securities Index Co. Ltd., FTSE Russell, Hang Seng Indexes, ISS-STOXX, JPX Market Innovation and Research (Tokyo Stock Exchange), Korea Exchange, Morningstar, MSCI Inc., NASDAQ OMX, Intercontinental Exchange, Inc, Parameta Solutions, Shenzhen Securities Information Co. Ltd., S&P Dow Jones Indices LLC, Taiwan Index Plus, and Tilt Indices LLC.

IIA members administer over three million indexes for their clients, covering many asset classes, including equities, fixed income, and commodities. Part of the IIA’s mission is to consider ways to promote best practices for index providers, which makes it a natural supporter of appropriate and proportionate industry standards. Its members are dedicated to promoting transparency, competition, sound operational practices, intellectual property rights, education, and effective index management practices. IIA members are independent index administrators who neither trade the underlying component securities of their indices nor directly create products for investors. Index providers set and publish the rules; asset managers build funds and other products on those indexes and set their fees; savers invest in those products. IIA members also publicly make available their methodologies and explain how their indices are created, calculated, or maintained.
