AMSTELVEEN, May 19 — KPMG International and Anthropic on Tuesday announced a global alliance to integrate Anthropic’s Claude artificial-intelligence model across KPMG’s worldwide workforce, the two firms said in a joint statement.

The deployment will cover 276,000 employees in 138 countries and territories, KPMG said, making it the largest professional-services rollout of Claude announced to date.

Claude will be embedded across several KPMG client and internal surfaces, the firms said. It will sit inside Digital Gateway, KPMG’s primary client-work platform, and inside the firm’s tax and legal client tools. It will also be used in KPMG’s cybersecurity practice for identifying and remediating system vulnerabilities, in modernising aging IT systems, and in building AI-driven products and processes for KPMG’s private-equity portfolio companies.

“This global alliance with Anthropic reflects our shared commitment to responsible AI, prioritizing security, trust, and governance as KPMG firms scale these capabilities to our clients and people around the world,” Bill Thomas, KPMG International’s global chairman and chief executive, said in the statement.

Daniela Amodei, Anthropic’s co-founder and president, characterised the rollout as the largest firm-wide commitment of its kind. “They’re rolling Claude out to 276,000 people across the business, and using it for client work in tax and private equity. That’s what a firm-wide commitment to AI looks like,” she said.

The KPMG alliance follows an expansion of Anthropic’s existing strategic partnership with PwC, announced earlier in the month, and an invite-only briefing in New York on May 5 at which Anthropic disclosed Claude deployments at JPMorgan Chase, Goldman Sachs, Citi, AIG, and Visa.

Anthropic and KPMG did not disclose the financial terms of the alliance.
