Microsoft Finally Opens the Azure Books: Two Segments, One $29.42B Number, and the Ghost of the DMA

For more than a decade, Microsoft’s cloud business has been a Rorschach test for investors. The company reported Azure’s growth rate — 33%, 39%, 42% — but never the number itself, leaving analysts to triangulate against Amazon’s AWS disclosures and Alphabet’s Google Cloud figures. That era ends now. In a presentation on Wednesday, Microsoft announced it will disclose quarterly Azure revenue in actual dollars for the first time, alongside a sweeping overhaul of its reporting structure that collapses three operating segments into two: Agents and Infra, and Devices and Consumer.

The headline number is substantial. Under the new perimeter, Azure grew 42% year over year to $29.42 billion in the June quarter — roughly a third of Microsoft’s total revenue. That immediately makes Azure one of the largest disclosed software businesses on the planet, and gives investors a clean quarterly read on the single most important engine of the AI infrastructure boom.

What Changed, Exactly

The prior three-segment structure had been in place since 2015, when “Intelligent Cloud,” “Productivity and Business Processes,” and “More Personal Computing” were drawn to reflect a company transitioning to subscriptions. Eleven years later, CEO Satya Nadella says AI has “blurred the boundaries between our products” and “reshaped our business models” — the old buckets no longer describe how the company actually operates.

The new structure:

• Agents and Infra — Azure, Microsoft 365 cloud products, productivity and server licensing, industry solutions, and frontier and support services. Inside this segment, Microsoft can now showcase momentum from its AI assistant portfolio: Microsoft 365 Copilot passed 30 million paid seats in July, up from 20 million in April, alongside the GitHub Copilot coding agent.
• Devices and Consumer — search and advertising, Xbox, Windows OEM licenses, and device sales.

The definition of Azure itself is narrowing at the same time. GitHub cloud services, developer cloud services, Security Copilot, and healthcare and life-sciences cloud products are all being stripped out. Those had been lumped in since the GitHub and Nuance acquisitions. “Under this reporting structure, Azure becomes more purely our consumption-based platform and infrastructure business,” Nadella wrote in the deck.

Microsoft is providing two years of recast financials and adjusted guidance, but will stop showing costs and operating margins for the three old segments. Guidance under the new structure targets $75.15–75.75 billion in Agents and Infra revenue for the coming quarter, with $14.7–15.2 billion in Devices and Consumer. Management also refined Azure’s outlook: 44–45% constant-currency growth, versus the 45% previously guided under the old metric. There are no changes to the overall revenue, cost, or operating expense outlook.

Why Now? Read the Calendar

Microsoft has not connected the timing to anything but the AI transition. But the calendar is hard to ignore. The European Commission opened market investigations into AWS and Azure in November 2025, asking whether cloud platforms should carry gatekeeper obligations under the Digital Markets Act. Cloud infrastructure doesn’t generate the monthly-active-user counts the DMA’s automatic thresholds assume, so regulators had to demonstrate market position the hard way — and doing that without a revenue figure was the central difficulty. Amazon has disclosed AWS revenue since 2015; Microsoft published only a growth rate.

In June, the Commission — working with the Dutch competition authority — reached a preliminary position that both AWS and Azure should be designated gatekeepers, finding they occupy “very strong positions.” A final decision is expected by the end of this year. Designation would bring interoperability duties, limits on self-preferencing, curbs on customer lock-in, and fines of up to 10% of global turnover for violations, escalating to 20% for repeat breaches.

The new Azure perimeter — a “purely consumption-based platform and infrastructure business” — lands strikingly close to the boundary Brussels has spent a year drawing. Microsoft’s first published Azure figure and the Commission’s final gatekeeper decision will now land in the same quarter. To be fair, reporting changes of this magnitude take many months to prepare, and nothing in the company’s framing suggests a concession. But from this quarter forward, the exact number European regulators would need to build a case is now printed in Microsoft’s own earnings release.

The OpenAI Elephant in the Segment

The disclosure also exposes something Microsoft has previously kept conveniently diffuse: just how much of Azure’s growth is one customer. Analysts at Stifel estimated in July that about half of Azure’s revenue growth in fiscal 2026 came from OpenAI, the ChatGPT maker that has committed to massive Azure compute commitments as its training and inference demands scale. Anthropic, ironically, has also become more reliant on Microsoft’s cloud as it diversifies infrastructure.

That concentration cuts both ways. It demonstrates Azure’s centrality to the frontier-AI economy — the two hottest labs in the industry are running on Microsoft iron. It also means a $29.42B quarterly figure has a single-name dependency embedded inside it, something investors can now interrogate quarter by quarter as OpenAI’s compute deals and Stargate-style buildouts evolve.

What It Means

For investors, the change converts the most important AI-infrastructure story from an argument into a data series. Expect AWS-vs-Azure comparisons, per-quarter growth decomposition, and margin analysis on a like-for-like perimeter for the first time.

For competitors, the disclosure sets a transparency bar. AWS discloses; Google Cloud discloses; now Azure discloses. Oracle — whose cloud business rides the same AI wave — remains the notable holdout.

For regulators, the timing is almost poetic. Europe spent a year trying to size a market whose leader refused to publish the number. Starting this quarter, Microsoft will hand it over every 90 days, in a perimeter that matches Brussels’ own definition almost exactly.

And for anyone tracking the agent economy, the segment names themselves are the tell. Microsoft no longer describes itself as a productivity company or a cloud company. It is, in its own accounting, an Agents and Infra company. When the org chart of the world’s second-most-valuable tech company reorganizes around AI agents as a reporting category, the platform-shift rhetoric has officially reached the balance sheet.

The first full quarter under the new structure will be reported in Microsoft’s fiscal Q1 FY2027 earnings. Watch the Azure line — everyone else will.
