“At KPMG, we’re innovating and redefining how work gets done,” said Bill Thomas, global chairman and CEO of KPMG International, in a statement. “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.” 

The partnership will involve close collaboration between KPMG and Anthropic in a number of ways. For one, Anthropic’s Claude LLM will be embedded directly into KPMG’s Digital Gateway, its global technology platform. While KPMG professionals already develop AI solutions and agents for client engagements, typically this has happened across fragmented tools and workflows. The key shift now is integration and speed, with capabilities embedded into core platforms so solutions can be built and scaled faster and with fewer handoffs.

“Building an AI agent to help clients adjust to changing tax regulations used to take weeks and required teams to switch between multiple tools and chat windows,” said Rema Serafi, vice chair of tax for KPMG U.S. , in a statement. “With Cowork and Managed Agents integrated in Digital Gateway, that same capability takes minutes. This is a totally different way of working.”

Beyond that, the agreement will also bring full access to Claude’s suite of AI capabilities to all 270,000 KPMG professionals, building on previous adoptions in the firm’s advisory, AI and Data Labs and enterprise support teams in the U.S. over the last two years. A KPMG spokesperson said this is more than just everyone having access to Claude: the AI is primarily being embedded into workflows. Claude, as part of the agreement, is integrated into platforms like Digital Gateway for client delivery and aIQ Chat for broader employee use, making it part of day-to-day work rather than a separate tool.

The alliance will also involve KPMG and Anthropic co-developing AI-based product offerings for specific client challenges. As an example, KPMG pointed to KPMG Blaze for PE clients, which is used to transform legacy systems into cloud-native solutions and automating the software development lifecycle. The KPMG spokesperson said that while solutions are developed from specific client needs, they are designed to evolve into repeatable, market-ready offerings over time. KPMG will bring these offerings to market, including industry-specific solutions built on Anthropic technology. 

As part of the partnership, KPMG will also serve as Anthropic’s preferred consultant for private equity. The firm will help deploy Anthropic AI capabilities to PE clients. KPMG already has teams working with Anthropic capabilities and is investing heavily in scaling that expertise, including large-scale training across the firm. The KPMG spokesperson clarified that the “preferred consultant” role reflects continued expansion of those capabilities, particularly for private equity clients, rather than starting from scratch. 

“KPMG works in industries where accuracy, accountability, and trust aren’t optional, and they’re applying the same standard to AI,” stated Daniela Amodei, co-founder and president of Anthropic. “They’re rolling Claude out to 276,000 people across the business and using it for client work in tax and private equity. They’re also bringing it into cybersecurity, where it helps find and fix vulnerabilities. That’s what a firm-wide commitment to AI looks like, and we’re proud to be the partner they chose.”

The alliance is designed to be integrated into client engagements, combining Anthropic’s technology with KPMG’s domain expertise to deliver solutions directly within KPMG-led work. The focus is less on separate joint staffing models and more on embedding shared capabilities into how KPMG delivers for clients. Further, Anthropic has given KPMG exclusive rights to bring its Claude-powered tax offering to market.

The partnership builds on a broader set of alliances and partnerships for KPMG with major AI providers. For example, last year the firm penned a deal with Google Cloud and its Agentspace platform to help clients build integrated and scalable AI platforms to enhance decision-making and effectively manage AI agents. KPMG will be the first Big Four firm to embed Claude directly into its flagship client delivery platform.
