KPMG has sealed a new partnership with AI company Anthropic to overhaul how its global staff use AI and make tax and consulting work faster. It is the first time Anthropic has plugged Claude into a Big Four firm's tax business platform; peers had mostly just given employees extra access to AI tools rather than rebuilding core platforms around Claude or OpenAI. KPMG is migrating part of its consulting business onto a Claude-centric platform running on Microsoft cloud, originally planned to go live by end-September, with more to follow. Audit will not embed Claude in core workflows and client service, but roughly 276,000 employees worldwide will get unified access to Claude tools. KPMG said the shift saves heavy man-hours: work that once took weeks, such as building tools to match new tax rules, now takes minutes. Anthropic also named KPMG a preferred consulting partner to serve private-equity firms and their portfolio companies.
