NEW YORK, Oct. 23, 2025 /PRNewswire/ — S&P Global (NYSE: SPGI) today announced plans to expand its S&P Dow Jones Indices (“S&P DJI”) index offering with the launch of the S&P 500 3AI Sector Rotator Index, an innovative benchmark that incorporates artificial intelligence (AI), through machine learning, to analyze company data and market signals to forecast sector performance, enabling systematic and adaptive allocations across S&P 500 sectors. This launch represents S&P DJI’s first AI-enhanced index using predictive modeling as a tool and marks the beginning of a broader initiative to explore the use of AI in index design.
As the demand for smarter and more adaptive investment tools grows, S&P DJI continues to deliver innovative benchmarks that blend traditional index methodology with cutting-edge technology. The S&P 500 3AI Sector Rotator Index utilizes scores generated by 3AI using a machine learning model to identify the three highest-ranked sectors at each rebalancing date. Designed to provide adaptive exposure to U.S. equity sectors, the index employs a rules-based methodology that incorporates AI technology and represents an extension of S&P DJI’s leadership in factor-based indexing.
“By applying machine learning to identify sector rotation opportunities, we are offering market participants a dynamic, proactive approach to overweighting sector exposures within the S&P 500,” said Cameron Drinkwater, Chief Product and Operations Officer at S&P Dow Jones Indices. “While the index is driven by machine learning models, it is uniquely transparent, bringing together the benefits of active systematic sector strategies with the transparency and robust governance of high-quality index design.”
3AI, a UK-based leader in AI-powered investment intelligence, provides the predictive analytics that underpin the S&P 500 3AI Sector Rotator Index. Trusted by global investment institutions, 3AI’s forecasting system applies explainable machine learning across global equities by mapping deep company analysis and business-cycle sensitivities to forward return forecasts, enabling adaptive, data-driven sector rotation. The collaboration integrates 3AI’s proprietary AI forecasting with S&P DJI’s rigorous index design, marking a milestone in the use of predictive intelligence for benchmark construction.
“This collaboration transforms AI from concept to capability in index construction,” said Jacob Ayres-Thomson, Founder and CEO of 3AI. “By combining S&P DJI’s benchmark expertise with 3AI’s predictive models, we’re building adaptive, forward-looking indices that reflect how information dynamically shapes markets—advancing the next generation of intelligent benchmarks.”
While S&P DJI has previously introduced AI-themed and multi-asset indices, this new initiative represents a significant advancement in using AI-related technology as a tool to facilitate constituent selection within an index.
