LSEG and Anthropic collaborate to make more financial data

accessible to Claude for Enterprise customers

LSEG today announced a collaboration with Anthropic granting access to data
licensed through LSEG products, like Workspace and Financial Analytics, for
Claude customers. This will be available through Anthropic's expanded Claude
for Financial Services offering - launched today.

 

This is the latest milestone in LSEG's AI strategy - LSEG Everywhere - which
is delivering trusted licensed data to scale AI in financial services. The
unparalleled depth, breadth, and quality of LSEG's AI-ready content and
taxonomies includes datasets stretching back over decades.

 

LSEG Everywhere includes the adoption of MCP and involves recent partnerships
with enterprise grade AI applications and data platforms including Microsoft,
Rogo, Snowflake and Databricks.

 

AI powered by LSEG's licensed AI-ready content in financial workflows

LSEG is granting access to data licensed through its products like Workspace
and Financial Analytics so customers can automate financial analysis. LSEG's
AI-ready content will be accessible through MCP in a phased rollout, starting
with LSEG Financial Analytics. Following this first release, LSEG will grant
Claude users access to more licensed AI-ready content, with initial
capabilities launching later this month and additional data categories to
follow.

 

LSEG is setting the standard for secure, scalable AI in financial services
with its open, LLM-agnostic, and infrastructure-oriented partnership approach
enabling workflows through open protocols such as MCP. This helps customers to
minimise cost and custom engineering and accelerate deployment times.

 

Through this collaboration, LSEG and Anthropic are also embedding mutual lead
generation processes. Claude for Financial Services customers can augment
their existing data with licences for LSEG's flagship Workspace solution. LSEG
is partnering with Workspace customers to secure licensed enterprise access to
Claude.

 

Ron Lefferts, Co-Head, Data & Analytics at LSEG, said:
"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."

 

Nicholas Lin, Head of Product, Financial Services at Anthropic, said:

"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."

MCP integration accelerates deployment, simplifies interoperability and
expands LSEG reach
This collaboration builds on LSEG's adoption of the Model Context Protocol
(MCP), the open standard pioneered by Anthropic. LSEG's MCP server, live in
the Claude MCP Partner Directory from Monday 27 October, ensures secure,
seamless access to LSEG's licensed AI-ready content.

The Claude MCP Partner Directory provides Enterprise customers with a single
point of access to a range of trusted partners and, via MCP, full
interoperability with their own AI systems and other third-party
applications.
