Microsoft is adding a consumption layer to its Copilot business: customers need a Microsoft 365 Copilot subscription to use Copilot Cowork, then pay for the work Cowork performs through usage-based Copilot Credits. That gives Microsoft a way to earn more when customers delegate more tasks to AI—but it also means customers’ costs depend on usage, not just the number of seats.
The strategy’s promise is clear in Microsoft’s cloud growth. Its financial test is harder: can repeat, profitable AI use justify the cost of building the computing capacity behind it?
A per-seat subscription gives Microsoft a recurring charge for access. Usage-based billing adds another potential revenue stream tied to task volume. In effect, the model lets customers start with a licensed user base and pay more as they make greater use of AI agents.
That structure changes what adoption numbers can tell us. A paid Copilot seat shows that a customer has subscribed; it does not, by itself, show how often the customer uses Cowork or how much work they are willing to pay it to do. For Microsoft, the commercial question is whether customers find enough value in those tasks to use them repeatedly. For buyers, the practical question is how to estimate and manage usage costs.
Microsoft reported fiscal Q4 2026 revenue of about $90 billion, up 18% year over year, while Azure grew 43%. Azure also passed $100 billion in annual revenue. The company’s commercial contracted backlog reached $678 billion, an 84% increase, pointing to substantial future demand.17
But backlog is not the same as revenue already earned, and strong cloud growth does not establish that every AI workload will be profitable. Those figures show scale and momentum; they do not settle the return-on-investment question.
Microsoft and OpenAI revised their partnership in April 2026. OpenAI can now serve customers across other cloud providers, while Microsoft remains its primary cloud partner, according to Reuters.1 The change loosens an important distribution tie. It makes Microsoft’s own Copilot products, cloud platform and customer relationships more central to its AI business rather than allowing the partnership alone to define its position.
Microsoft’s AI opportunity requires substantial infrastructure. One estimate put quarterly capital spending at about $36 billion; the same report said free cash flow fell 23%.20 Those figures make the key trade-off tangible: usage-based revenue can help fund AI capacity if customers generate enough recurring, profitable demand. If monetization lags, high investment can weigh on cash generation.
That is why the most useful indicators are not just Copilot availability or Azure growth. Watch whether customers use Cowork repeatedly, whether that usage generates revenue beyond the seat subscription, and whether the economics improve as Microsoft serves more work.
Microsoft shares rose about 37.5% during the July–September period, according to an October market summary.19 A separate September comparison put Microsoft at about 27 times earnings and Apple at about 37 times.
17 Both are snapshots tied to particular dates and measures, not lasting verdicts on either company’s value.
The lower multiple in that comparison may look attractive, but it does not remove the central risk: investors still need evidence that AI demand can translate into durable earnings and cash flow. For Microsoft, the decisive measure is not simply how many customers have Copilot seats or how large the backlog becomes. It is whether profitable, repeat Cowork usage can turn AI infrastructure spending into lasting returns.
