Summary
Thousands of LSEG employees gained ChatGPT Enterprise and OpenAI API access within weeks, with teams using the tools to summarize market data, draft reports, prototype products and speed internal workflows.
Product release cycles fell from 3–6 months to 2 weeks, while customer delivery timelines dropped to about 4 weeks from request to production as analysts and business teams reduced manual research and documentation work.
LSEG said it paired the rollout with model evaluation, human review for critical outputs, and strict privacy and security controls, aiming to scale adoption safely across product, engineering, research and operations.
The group, which serves more than 40,000 customers and 400,000 end users in about 190 markets, is now pushing beyond productivity gains toward AI embedded in research, product development and client-facing tools.
