Barclays is expanding its strategic collaboration with Anthropic to integrate secure, enterprise-grade AI systems across its global operations. The bank aims to accelerate software development, modernize legacy systems, and improve operational efficiency by rolling out Claude Code to 50% of its developer population by the end of 2026.

  • Barclays' Colleague Knowledge Assistant, powered by retrieval-augmented generation, has been live since 2025 and is used by over 16,000 colleagues to support more than 20 million UK retail customers.
  • The assistant has handled over one million searches, resulting in faster access to information and quicker customer support.
  • In the Global Markets business, Claude models process approximately 120,000 emails daily to classify and enrich client enquiries, reducing manual handling activity.

The partnership emphasizes responsible deployment with robust governance and security controls. Barclays expects Claude to be used by a majority of software engineers by 2027 as part of its long-term commitment to improving productivity and customer outcomes.
