London Stock Exchange Group (LSEG) deployed OpenAI’s ChatGPT Enterprise across its global data platform to accelerate insight generation. The financial‑market infrastructure provider serves 40,000 customers in roughly 190 markets, and had already invested in AI‑driven analytics. By integrating generative models directly with trusted data, LSEG aimed to replace manual synthesis with real‑time, AI‑assisted decision support to meet client AI expectations.

Teams in product, engineering, research and operations gained access within weeks, using the API to draft reports, synthesize market data, and prototype features. Analysts now summarize large data sets in minutes, cutting research time dramatically. The rollout included a governance framework—model evaluation, human‑in‑the‑loop review, and strict privacy controls—ensuring compliance while empowering users and maintaining strict regulatory standards.

After adoption, product release cycles collapsed from three‑to‑six months to two weeks, and customer delivery timelines fell to roughly four weeks from request to production. Thousands of staff report faster research, smoother cross‑functional collaboration, and higher innovation velocity. LSEG’s next phase embeds AI deeper into research and client‑facing tools, leveraging its Model Context Protocol to keep data verifiable for global markets today.
