Ernst & Young is betting big on artificial intelligence, committing over $1B specifically toward a next-generation assurance platform that leans heavily on Microsoft’s cloud and AI infrastructure. The investment is part of EY’s broader $2.5B technology initiative, first announced in 2021, which has steadily evolved from a general modernization effort into a full-blown AI transformation play.
The partnership isn’t a simple handshake deal where two companies split a check down the middle. EY is the one writing the big checks here, while Microsoft provides the technological plumbing, specifically its Azure cloud services and AI models, that makes the whole thing work.
What EY is actually building
At the center of all this is the EY.ai platform, which launched in September 2023. That platform alone has attracted $1.4B in investment, focused on weaving AI capabilities into the consulting and assurance work EY does for its clients.
Think of it this way: auditing a massive corporation’s financial statements used to mean armies of accountants combing through spreadsheets. EY wants to replace a significant chunk of that manual labor with AI agents that can process enormous volumes of journal entry data, flag anomalies, and surface insights that humans might miss or take weeks to find.
