KPMG deploys Claude to 276,000 employees as three Big Four firms lock in Anthropic
AnalysisKPMG announced on May 19 that all 276,000 employees across 138 countries will access Claude through a new Digital Gateway integration running on Microsoft Azure. The deployment embeds Claude Cowork and Managed Agents into KPMG's core client platform, with an initial focus on tax and private equity clients. KPMG's tax leadership cited a concrete result: a regulatory compliance agent that previously took weeks to build inside Digital Gateway now takes minutes. Separately, Deloitte announced a 470,000-employee Claude deployment within 60 days, and PwC committed to its own enterprise-wide rollout. Three of the Big Four accounting firms now run Claude at scale; EY is the visible holdout.
