Barclays Scales Claude to Upgrade Operations and Improve Client Experience

Barclays is expanding its enterprise AI partnership with Anthropic, deploying Claude across operations, software development, and customer servicing at scale. The bank's Colleague Knowledge Assistant, built on a retrieval-augmented generation architecture, has been adopted by more than 16,000 employees and has processed over 1 million searches to support Barclays' 20-plus million UK retail customers. In Global Markets, Claude models classify and route approximately 120,000 emails per day, reducing manual handling across client inquiry workflows. Claude Code adoption is targeted at 50% of Barclays' developer population by end of 2026, rising to a majority of software engineers by 2027, with governance, security controls, and human oversight embedded throughout the rollout.
