London Stock Exchange Group (LSEG), a leading global financial markets infrastructure provider supporting over 40,000 customers and 400,000 end users, deployed ChatGPT Enterprise and OpenAI APIs across its organization to transform how employees interact with data and generate insight (OpenAI News). The rollout enabled thousands of employees globally within weeks, with teams across product, engineering, research, and operations using AI to draft reports, synthesize market data, prototype products, and streamline workflows (OpenAI News).
Results included reduced product release cycles from 3–6 months to 2 weeks, accelerated customer delivery timelines to approximately 4 weeks from request to production, and increased analyst productivity through faster research and synthesis (OpenAI News). For commerce practitioners, LSEG's approach—combining broad employee access with embedded governance frameworks, human-in-the-loop review, and strict data privacy controls—demonstrates how enterprise AI adoption can scale safely in regulated industries without sacrificing speed or innovation velocity (OpenAI News).
LSEG is now expanding beyond individual productivity to workflow-level AI applications, including integrating AI directly into research processes and client-facing solutions through systems like its Model Context Protocol, allowing customers to access verified information within AI workflows (OpenAI News).
