Barclays, the British universal bank, is expanding its strategic collaboration with Anthropic to integrate secure, enterprise-grade AI systems across its global operations. The expansion includes deploying Claude to accelerate software development, modernize legacy systems, and improve operational efficiency.

Barclays expects Claude Code adoption to reach 50% of its developer population by the end of 2026, rising to a majority of software engineers in 2027. The integration reflects a shared commitment to deploying AI responsibly, reliably, and in ways that deliver real outcomes, such as providing faster support for customers.

"The true measure of any technology is the impact it has on customers, clients, and colleagues, and the outcomes it enables," said Anne Marie Darling, Group Co-Chief Operating Officer at Barclays.

"Expanding the use of Claude across Barclays is about more than adopting AI. It is about transforming how work gets done: reimagining processes, enhancing customer and client experiences, and building a simpler, more efficient organization within a secure and well-governed environment."

"Software engineering and cyber security are both being reshaped by increasingly capable AI systems," said Craig Bright, Group Co-Chief Operating Officer at Barclays. "We're moving towards AI as an increasingly agentic capability embedded within how we build, test, secure, and operate technology.

At Barclays, we're using Claude to help modernize legacy platforms, improve software quality, and allow our technical experts to focus on the most complex challenges."

Claude powers knowledge assistance to speed up customer servicing. One example of the partnership already in action is Barclays’ Colleague Knowledge Assistant, which helps Barclays UK employees find information and answers more quickly when supporting their over 20 million UK retail customers. The capability, which has been live since 2025, is powered by Claude through a retrieval-augmented generation architecture.

Enhancing operational efficiency in Barclays’ Global Markets business, Claude models are helping streamline how client inquiries are processed and managed. Teams use Claude models to classify, enrich, and determine the optimal processing route for incoming emails, helping to prioritize and ensure requests contain the information needed for operations colleagues to take action.
