Barclays Claude rollout

A larger Claude deployment at Barclays

Barclays expects half of its software developers to use Anthropic’s Claude Code by the end of 2026, Bloomberg reported on October 1, citing a joint statement from the two companies. The British bank plans a broader rollout in 2027 as it works on legacy systems and operational efficiency. The figure is a future adoption target, not a reported count of developers already using the tool.

Existing use in client inquiries

Bloomberg says Barclays’ markets business already uses Anthropic models to help manage client inquiries. The report says the relevant platform handles about 120,000 emails per day. That is a measure of the platform’s email volume; the available account does not establish that Claude reads or resolves every message without human involvement. Barclays and Anthropic have not published measured savings, error rates or a detailed rollout schedule in the reviewed report. Those results will matter more than the adoption target when assessing the expansion.
