Oracle and Microsoft both delivered strong cloud expansion in fiscal 2026, but they represent different investment profiles. Oracle is scaling cloud infrastructure at a much faster rate from a smaller base and is booking very large contracts, including arrangements connected with artificial-intelligence computing. Microsoft generates far more cloud revenue inside a broad software, services, advertising and devices business, with Azure growth still substantial. Oracle’s expansion also required heavy infrastructure spending and new financing, while Microsoft’s reported results show greater scale and diversification. The figures below are a fundamentals comparison, not a current share-price or valuation recommendation.
What does an Oracle-versus-Microsoft cloud-stock comparison actually measure?
The cleanest comparison combines growth, absolute revenue, business mix, contracted demand, cash generation and the funding required to build data-center capacity. Looking only at a percentage growth rate can make a smaller business appear stronger than a much larger one; looking only at scale can hide a faster-changing opportunity.

The companies also use different fiscal calendars and different labels. Oracle’s fiscal year ended May 31, 2026, while Microsoft’s ended June 30, 2026. Oracle reports cloud revenue with explicit infrastructure and applications lines. Microsoft reports a company-defined “Microsoft Cloud” total and separately gives growth for “Azure and other cloud services.” Those categories overlap in purpose but are not identical measurements.
| Company and reporting period | Total revenue | Primary cloud measure | Cloud growth | Additional cloud line |
|---|---|---|---|---|
| Oracle, fiscal year ended May 31, 2026 | $67.4 billion | Cloud revenue: $34.0 billion | Up 39% | Cloud infrastructure: $18.1 billion, up 77%; cloud applications: $15.9 billion, up 11% |
| Microsoft, fiscal year ended June 30, 2026 | $331.839 billion | Microsoft Cloud: $214.4 billion | Up 27% | Azure and other cloud services revenue increased 41% |
These are company-reported fiscal-year figures. They should not be read as if Oracle’s combined cloud total and Microsoft Cloud were a standardized industry statistic.

Which company is growing cloud revenue faster?
On the reported growth rates, Oracle’s cloud infrastructure is expanding faster than Microsoft’s comparable Azure growth rate. Microsoft, however, is applying a strong growth rate to a substantially larger cloud operation, so the absolute dollars added can be greater even when the percentage is lower.
Oracle’s growth profile
Oracle reported $34.0 billion of cloud revenue for fiscal 2026, up 39%. Within that total, cloud infrastructure revenue reached $18.1 billion, up 77%, while cloud applications revenue was $15.9 billion, up 11%. The split matters: infrastructure captures demand for computing and related capacity, whereas applications represent software delivered through the cloud. A 77% infrastructure rate therefore does not describe every part of Oracle’s cloud business.
Microsoft’s growth profile
Microsoft reported $214.4 billion in Microsoft Cloud revenue, up 27%. Its narrower “Azure and other cloud services” line increased 41%. Microsoft’s cloud figure sits inside a company that also sells productivity software, business applications, advertising, gaming and devices, so the reported cloud total is not a pure infrastructure measure.
The useful conclusion is two-dimensional: Oracle has the sharper infrastructure growth curve, while Microsoft has far greater cloud scale. Investors should track both the rate and the revenue base that produces it.
How comparable are Oracle’s cloud figures with Microsoft’s cloud figures?
They are directionally useful but not interchangeable. Oracle gives separate infrastructure and applications revenue, while Microsoft’s headline cloud number aggregates its own set of cloud services and products.
- Oracle cloud revenue: a combined figure that includes infrastructure and applications. Its infrastructure and applications lines allow a reader to see which side is driving the total.
- Microsoft Cloud: Microsoft’s reported aggregate for its cloud portfolio, not a market-wide definition of cloud revenue.
- Azure and other cloud services: Microsoft’s narrower growth disclosure and the closest of the supplied Microsoft measures to an infrastructure-oriented comparison, although it still is not an exact match for Oracle Cloud Infrastructure.
Because the denominators and included products differ, a direct statement such as “Oracle’s cloud is growing faster than Microsoft’s cloud” needs a qualifier. It is accurate for the disclosed infrastructure-versus-Azure growth comparison, but not a like-for-like claim about the two headline cloud totals.

What do Oracle and Microsoft’s backlog figures reveal about AI demand?
Both companies reported exceptionally large remaining-performance-obligation figures, indicating substantial contracted business. The labels and composition differ, so the totals should be used as demand indicators rather than treated as equivalent backlogs or as guaranteed near-term revenue.
| Company | Reported measure | Fiscal 2026 amount | Year-over-year change | Interpretive caution |
|---|---|---|---|---|
| Oracle | Remaining performance obligations (RPO) | $638 billion | Up 363% | Oracle said much of the increase in the third and fourth quarters reflected large-scale AI contracts. |
| Microsoft | Commercial remaining performance obligation | $678 billion | Up 84% | This is Microsoft’s commercial RPO measure and may differ in duration, products and recognition pattern from Oracle’s RPO. |
Oracle’s results release states that most of the RPO increase in both its third and fourth quarters came from large-scale AI contracts in which the customer prepaid Oracle for GPUs or bought and supplied the GPUs to Oracle. That detail helps explain why a contract can enlarge reported obligations without immediately producing the same amount of recognized revenue or cash profit.
Neither company’s RPO number, by itself, establishes when revenue will be recognized, how profitable each contract will be, whether customers are concentrated, or whether every planned data-center deployment will be completed on schedule. Contract duration, cancellation terms, customer credit quality and required capital spending all affect conversion.
Does Oracle’s faster infrastructure growth translate into stronger cash generation?
Not in fiscal 2026. Oracle generated positive operating cash flow but reported negative free cash flow as it invested heavily in cloud infrastructure, making funding needs a central part of the comparison.

Outbyte PC Repair FREEClear out junk files and repair common Windows errorsFree Scan →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Oracle’s fiscal 2026 cash figures
- Operating cash flow: $32.0 billion.
- Free cash flow: negative $23.7 billion.
- Debt raised during the year: $43 billion.
- Equity raised during the year: $5 billion.
Free cash flow is what remains after operating cash flow and capital expenditures. A negative result can occur during an intentional build-out, but it means the business did not fund that year’s expansion from internally generated cash alone. Debt and equity financing can bridge the gap, while also creating interest, refinancing, dilution and execution considerations.
What Oracle said about fiscal 2027 financing
Oracle expects approximately $40 billion in debt and equity financing in fiscal 2027. This is a forward-looking company expectation, not financing that has already occurred. The eventual amount, mix and terms could change with construction schedules, customer commitments, capital-market conditions and operating cash flow.

How to read Microsoft’s position in this comparison
The supplied Microsoft annual-report figures provide cloud revenue, growth and commercial RPO, but they do not provide a directly comparable Oracle-style set of fiscal-2026 free-cash-flow and financing figures in this evidence set. It would therefore be unsound to claim that Microsoft converted cloud growth into more cash, used less debt, or carried lower funding risk without the corresponding period-specific data.
Are Oracle and Microsoft pure-play AI cloud companies?
No. Both are diversified technology companies with cloud businesses, and the diversification changes how investors should interpret an AI-driven cloud thesis.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesOracle’s mix
Oracle reports cloud alongside software, hardware and services. Its applications business includes established enterprise software, while infrastructure expansion adds exposure to computing capacity and AI workloads. The combination means Oracle can benefit from infrastructure demand without being valued or managed as a single-product cloud provider.
Microsoft’s mix
Microsoft describes a broad portfolio that includes cloud-based solutions, productivity software, advertising and devices, among other activities. Azure growth can influence the company’s results materially, but Microsoft’s earnings and risks also reflect recurring software subscriptions, enterprise applications, consumer products and advertising markets.
Diversification can cushion a slowdown in one product line, but it can also make a headline cloud-growth comparison less informative about the performance of the entire company. A reader deciding between the stocks should identify whether the intended exposure is infrastructure capacity, enterprise software, AI services or a broad technology platform.
What should investors examine before choosing between the two stocks?
A disciplined comparison moves from reported results to the assumptions needed to sustain them. Use the following sequence rather than relying on a single growth percentage.

- Match the reporting periods. Start with Oracle’s year ended May 31, 2026, and Microsoft’s year ended June 30, 2026. Do not combine quarterly figures from different periods without labeling the dates.
- Separate infrastructure from applications. Oracle’s infrastructure growth and applications growth have different economics and demand drivers. Keep Microsoft’s Azure growth separate from the broader Microsoft Cloud total.
- Put growth beside scale. Record both the percentage increase and the associated revenue base. A smaller line can grow faster while contributing fewer dollars than a mature, larger segment.
- Test backlog quality. Identify whether the figure is Oracle RPO or Microsoft commercial RPO, then examine contract length, prepayments, customer concentration and the timing of delivery. Do not treat either total as immediate sales.
- Follow the cash conversion. Compare operating cash flow, capital expenditures and free cash flow over several periods. For Oracle, fiscal-2026 negative free cash flow makes the pace and productivity of infrastructure investment especially important.
- Assess funding and dilution. Include the debt and equity required to build capacity. Oracle’s disclosed fiscal-2026 raises and fiscal-2027 expectation should be modeled as financing inputs, not as proof that future returns will cover them.
- Define the exposure you want. Decide whether you prefer a faster-growing infrastructure business, a larger diversified cloud platform, or a blend of cloud and non-cloud operations. The answer depends on risk tolerance and portfolio role, not only on the highest growth rate.
- Only then add market data. Compare current share price, enterprise value, earnings, free-cash-flow multiples, net debt and analyst expectations using the same measurement date. Those valuation and performance inputs are not established by the fiscal results summarized here.
What are the main risks behind Oracle’s AI-cloud expansion?
Oracle’s reported growth creates opportunity but also exposes several execution questions.
- Capacity delivery: AI contracts require data-center space, networking, power, GPUs and operating capability. Delays can defer revenue while costs are incurred earlier.
- Capital intensity: Negative free cash flow means expansion is consuming cash after operations. Returns depend on utilization and pricing, not simply on contracted capacity.
- Financing dependence: Large debt and equity raises can increase interest expense, refinancing exposure or shareholder dilution.
- Contract economics: Prepaid GPU arrangements can support funding, but the timing and margin profile of the associated services still matter.
- Concentration: A few large AI customers can make RPO growth look dramatic while increasing dependence on their deployment schedules and credit strength.
These are analytical checkpoints, not claims that any particular contract will fail. They explain why backlog growth and infrastructure growth should be evaluated together with cash flow.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What are the main risks behind Microsoft’s cloud position?
Microsoft’s larger cloud base and diversified portfolio reduce dependence on a single revenue line, but they do not eliminate execution or valuation risk.
- Growth deceleration: Maintaining a high rate on a large base requires sustained customer additions, workload migration and usage growth.
- Infrastructure economics: AI services require substantial computing investment, and margins depend on hardware costs, power, networking and utilization.
- Portfolio complexity: Microsoft Cloud growth can coexist with different results in productivity software, advertising, devices or other businesses, so company-wide performance may diverge from Azure trends.
- Backlog conversion: Commercial RPO is a demand signal, but timing and profitability depend on the contracts behind it.
- Market expectations: A strong operating result does not establish that a stock is cheap. Valuation requires a dated share price and comparable financial measures.
Which stock is cheaper or the better buy?
The supplied fiscal results do not answer that question. No current share prices, valuation multiples, recent returns or analyst estimates are established here, and those measures change daily.

Pick the symptom - the matching free tool is one click away.
A responsible stock comparison would specify a measurement date and then calculate comparable ratios such as price-to-earnings, enterprise-value-to-sales, enterprise-value-to-free-cash-flow and net-debt-to-cash-flow. It would also adjust for the companies’ different fiscal year-ends and business mixes. Without those inputs, naming a cheaper or superior stock would be speculation rather than analysis.
What is the practical takeaway from Oracle versus Microsoft?
Oracle offers the more rapid reported cloud-infrastructure growth and a dramatic increase in RPO, but it is funding an expensive capacity build while carrying negative fiscal-2026 free cash flow. Microsoft offers a much larger cloud revenue base, strong Azure growth and a more diversified operating model. The central trade-off is therefore speed and infrastructure expansion on one side versus scale and diversification on the other.

Frequently Asked Questions
Why do Oracle and Microsoft have different fiscal year-end dates?
Companies choose their own fiscal calendars, so Oracle’s fiscal 2026 ended on May 31, 2026, while Microsoft’s ended on June 30, 2026. The one-month difference can affect seasonality and makes it important to label periods when comparing quarterly trends.
Recommended Free Tools
Does a large remaining-performance-obligation number guarantee future revenue?
No. RPO represents contracted obligations under each company’s reporting rules, but recognition depends on delivery, contract duration and other conditions. It does not by itself show the timing, margin or collectability of the related revenue.
Did Oracle or Microsoft stock outperform in fiscal 2026?
That cannot be determined from the operating figures alone. A valid performance comparison needs start and end prices, an explicitly stated date range and an adjustment for dividends or corporate actions.
Why can customer-supplied GPUs appear in Oracle’s AI contracts?
Oracle reported that some large AI customers bought and supplied the GPUs themselves, while others prepaid Oracle for the GPU purchase. This arrangement can change who funds the hardware and when cash arrives, but it does not remove the need to evaluate deployment timing and service economics.
