British universal bank Barclays is expanding its strategic collaboration with Anthropic to integrate secure, enterprise-grade AI systems across its global operations. According to the announcement, the bank is extending 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, and a majority of software engineers in 2027. The expanded rollout builds on existing implementations. Since 2025, Barclays has operated a Colleague Knowledge Assistant powered by Claude through a retrieval-augmented generation architecture. More than 16,000 employees have adopted the tool, utilizing it to find information quickly when supporting over 20 million UK retail customers, handling over one million searches to date. Furthermore, within Barclays' Global Markets business, Claude models process approximately 120,000 incoming emails each day by classifying, enriching, and determining optimal processing routes to reduce manual handling activity. Executives from both organizations emphasized the importance of disciplined governance, robust security controls, and human oversight. Paul Smith, Chief Commercial Officer at Anthropic, noted that Barclays maintains high standards for AI deployment, combining frontier capabilities with strong security. The collaboration reflects a shared commitment to deploying AI responsibly and reliably to improve productivity, customer outcomes, and operational resilience within a large-scale enterprise.
