From Data to Decisions: How LSEG Is Scaling Trusted AI

Global financial markets infrastructure provider LSEG (London Stock Exchange Group) is integrating generative AI into its vast financial data ecosystem through a partnership with OpenAI. To address existing manual data synthesis and fragmented workflow problems, LSEG has deployed ChatGPT Enterprise and the OpenAI API company-wide.

LSEG is driving responsible AI scaling by building a governance framework that includes a model evaluation framework, Human-in-the-loop review processes, and strict data privacy and security controls. This enables the company to boost internal operational efficiency while also helping customers leverage LSEG's data within familiar environments.

Key outcomes from AI adoption include:

• Product release cycles: Shortened from the existing 3–6 months to 2 weeks
• Customer service response: Approximately 4 weeks from request to production deployment
• Work efficiency: Faster analyst research and data synthesis, and reduced time to turn ideas into prototypes
• Organizational innovation: Thousands of employees worldwide began using AI tools within weeks
