The London Stock Exchange Group (LSEG) has announced a significant collaboration with artificial intelligence firm Anthropic, aimed at embedding its vast reserves of financial data directly into Anthropic’s new “Claude for Financial Services” offering. The move marks a key development in LSEG’s AI strategy, dubbed “LSEG Everywhere,” which focuses on making its trusted, licensed data readily available to scale AI applications across the financial sector.
The partnership will allow enterprise customers using Anthropic’s Claude AI to access LSEG’s data and analytics, including its flagship Workspace product, to automate complex financial analysis. This integration is designed to empower “agentic AI” workflows, enabling Claude to perform tasks such as summarising earnings calls, scanning due diligence materials, and identifying market signals with greater speed and accuracy, all underpinned by LSEG’s decades of curated data.
Ron Lefferts, Co-Head of Data & Analytics at LSEG, commented on the collaboration, stating, “LSEG has a long-established reputation for our open, partnership approach and meeting our customers wherever their workflows are taking place. Secure, enterprise grade AI applications, such as Claude, and open standards like MCP are expanding the opportunities for LSEG to build deep partnerships with customers. With Claude for Financial Services, our customers can now access LSEG’s unmatched financial data and insights to power and scale agentic AI directly within their workflows.”
This initiative is facilitated by the adoption of the Model Context Protocol (MCP), an open standard pioneered by Anthropic to create a universal interface between AI models and external data sources. LSEG has launched a dedicated MCP server, which is now live in the Claude MCP Partner Directory. This open, LLM-agnostic approach is intended to simplify interoperability, reduce custom engineering costs, and accelerate deployment times for financial institutions looking to leverage AI.
For Anthropic, this is a strategic enhancement of its recently launched financial services offering, which already includes integrations with data providers like S&P Global, Moody’s, and Morningstar, as well as new tools such as a Microsoft Excel add-in. The addition of LSEG’s extensive datasets aims to provide the crucial, high-quality information required to minimise AI ‘hallucinations’ and ensure the reliability demanded by the highly regulated financial industry.
Nicholas Lin, Head of Product for Financial Services at Anthropic, commented: “Combining Claude’s intelligence with data and context offers real value. With LSEG’s trusted data, Claude is able to summarize earnings calls, scan diligence materials, trigger agentic workflows and surface instant market signals – all with enterprise-grade controls.”
The partnership is the latest in a series of AI-focused collaborations for LSEG, including wide-ranging initiatives with Microsoft, Databricks, and Snowflake. These moves underscore a broader industry trend towards leveraging large language models (LLMs) and generative AI to process vast amounts of unstructured and structured data, seeking to unlock new efficiencies and analytical insights in financial markets.
The rollout of LSEG data to Claude users will be phased, beginning with LSEG Financial Analytics, with additional datasets and capabilities to follow in the coming months. The collaboration also includes mutual lead generation, where customers of each firm will be encouraged to adopt the services of the other.
