From data to decisions: how LSEG is scaling trusted AI

London Stock Exchange Group is scaling trusted artificial intelligence across its global business through a partnership with OpenAI. Facing challenges with manual synthesis and fragmented workflows, LSEG selected OpenAI based on model quality, enterprise readiness, and alignment with existing customer demand. According to the source, the financial markets infrastructure provider deployed ChatGPT Enterprise and OpenAI APIs to thousands of employees within weeks, enabling teams in product, engineering, research, and operations to draft reports, prototype products, and streamline internal workflows. Analysts use the tools to summarize large volumes of financial and market information, reducing time spent on initial research and accelerating insight generation. To manage risk, LSEG embedded governance from the outset, including model evaluation frameworks, human-in-the-loop reviews for critical outputs, and strict data privacy controls. Group Director for AI Products Max Grigoryev noted that the goal is to enable employees and customers with tools to move faster while remaining safe and compliant. LSEG achieved accelerated customer delivery timelines of approximately four weeks from request to production, increased analyst productivity, and expanded innovation velocity. Moving forward, LSEG plans to expand beyond individual productivity gains to deeply embedded, workflow-level AI applications, including integrating OpenAI models with its trusted data to give customers precise, verifiable information directly within AI workflows.
