Anthropic is on a mission to make Claude a default AI tool for corporate America — and the Big Four firm PwC is now one of its biggest routes in.

On Thursday, PwC and Anthropic announced a major expansion of their alliance, a move that will help their efforts to embed AI into the underlying infrastructure of large companies.

The expanded partnership will focus on three areas: helping engineering teams build agentic AI tools for clients, deploying AI across the dealmaking process, and reinventing clients' underlying operating models with AI.

PwC will train and certify 30,000 US employees in Claude Code and expand the product to its global workforce of 364,000. The two companies will also establish a joint Center of Excellence.

The partnership brings together Anthropic's AI capabilities and PwC's industry experience, a combination that helps organizations "move from exploration to enterprise-wide impact with greater confidence," said Paul Griggs, a senior partner and CEO of PwC US, in a press release.
