EY and Microsoft Announce $1 Billion Initiative to Scale Enterprise AI

EY and Microsoft announced in a press release a joint investment exceeding 1 billion dollars to accelerate enterprise AI transformation. The new initiative will deploy integrated teams of EY consultants and Microsoft engineers to help clients implement AI solutions across key business areas including finance, tax, risk, human resources, and supply chain.

EY will act as “Client Zero,” using its own operations to validate the technologies involved. The firm has already rolled out Microsoft 365 E7: The Frontier Suite and scaled Copilot to more than 400,000 employees. Initial internal results showed a 15 percent productivity increase among 150,000 early users. EY also reported faster finance operations through Microsoft Power Platform and significant cost reductions via Copilot Studio.

The collaboration will focus on developing secure, industry-specific AI systems designed to optimize operations within sectors such as financial services, industrials, energy, consumer goods, government, and healthcare. The offering will feature shared governance, aligned commercial models, and accountability across both organizations.

EY has also embedded AI into its assurance and tax platforms using Microsoft Azure, Foundry, and Fabric. These integrations have automated data extraction, reduced manual workloads by up to 90 percent, and improved audit workflows for more than 130,000 professionals worldwide.
