Microsoft said its AI business is now running at a $37.00 billion annual revenue run rate and widened its $1.00 billion alliance with EY, a move that ties Azure AI and Copilot more tightly to enterprise finance, tax, risk and HR work.
The disclosure lands while investors are trying to separate real AI revenue from the cost of building the infrastructure behind it. Microsoft’s planned 2026 capital spending stands at $190 billion, and that scale has become part of the story as much as the growth itself. The company is betting that more AI use inside everyday enterprise workflows will lift cloud consumption and average revenue per user, not just add another product line.
That is why the EY deal matters now. By embedding Microsoft tools deeper into a firm that handles some of the most routine and regulated work in corporate life, the company is trying to make AI useful where budgets are measured in hours saved, faster reviews and fewer manual steps. Microsoft has also broadened its AI footprint in recent weeks with new in-house models and a series of Azure- and Copilot-based solutions from partners across governance, security and industry workflows.
The promise is clear, but so is the strain behind it. Heavy capital spending can squeeze margins before it shows up in earnings, and the most bearish analysts are already assuming profitability will be pressed toward 36 percent as the buildout continues. Microsoft’s broader narrative still points to $504.4 billion in revenue and $192.9 billion in earnings by 2029, but that path assumes 16.6% annual revenue growth and a roughly $67.7 billion increase in earnings from $125.2 billion today.
For now, the company has given investors a rare hard number for the AI side of the business and a high-value customer example of how it wants that business to spread. What it has not yet shown is how quickly the EY alliance, or the wider Azure AI push, turns into incremental profit rather than just more spending on the way to it. Msft stock was up 7.6% as the market digested the latest signal that AI is moving from narrative to measurable business.
