LSEG Links Its Market Feeds to ChatGPT, Letting Users Pull Data on Demand

London Stock Exchange Group plans to connect its financial data and analytics to OpenAI’s chatbot so licensed users can pull prices, news and analytics without leaving the ChatGPT screen.

LSEG will integrate data from products such as Workspace and Financial Analytics directly into ChatGPT, where, users who hold valid LSEG credentials will log into the chatbot and then request market data or news that LSEG licenses to them.

It will start with LSEG Financial Analytics and then add more data types and functions after the first launch phase, it announced on Wednesday.

How the MCP connector works

The rollout will begin in the week of 8 December 2025. At that point, ChatGPT will act as a single interface where users can ask questions in plain language, while the connector in the background fetches structured data from LSEG systems.

“LSEG’s connector within ChatGPT combines all the benefits of a secure, enterprise AI platform with a seamless MCP connection and the unparalleled depth, breadth and quality of financial data, analytics, news and commentary that LSEG provides,” Emily Prince, Group Head of AI at LSEG, commented.

LSEG said its content is “AI-ready”, which means it prepares data in a format that machine-learning tools can use more easily. The MCP connector then delivers that content to ChatGPT in a controlled way, so financial firms can keep using licensed data under existing rules.

Users will reportedly be able to ask the model to analyze or summarize that information, which could reduce the time they spend switching between terminals, research tools and emails.

What users will be able to do

The integration aims to help traders, sales teams and analysts get faster answers to questions about markets or specific instruments. Over time, LSEG plans to unlock more datasets and features through the same connector so users can run deeper analysis with natural language prompts.

Additionally, the partnership with OpenAI also covers internal use. LSEG will grant access to ChatGPT Enterprise to an initial group of around 4,000 employees. Staff will use the enterprise-grade version of the chatbot to automate routine tasks, draft documents and improve internal workflows.

In a similar collaboration involving AI adoption in the financial markets, S&P Global announced a partnership with Anthropic to integrate its trusted financial data into Claude, the AI chatbot, in July.

The move lets hedge fund managers, private equity analysts, and investment bankers query complex financial questions and get quick, reliable answers right inside Claude.​
