How Oracle Makes Money: Inside Its Cloud, Software and $638 Billion AI Bet

Oracle is earning more revenue and operating profit than ever, yet it is also borrowing tens of billions of dollars and reporting deeply negative free cash flow. That is not a contradiction. It is what happens when a mature software cash machine tries to become an AI infrastructure giant at record speed. The old Oracle collects high-margin tolls from databases and software support. The new Oracle is using those tolls, customer advances, debt and fresh equity to build something closer to a digital power grid.

Let's break down how Oracle makes money from cloud infrastructure, enterprise applications, database licences, software support, hardware and services.

Then we will track which business generates the most revenue, which one drives growth, where the cash is going, whether Oracle can carry its debt and how investors should value a company that no longer behaves like a traditional software business.

Oracle Business Model: From Databases to Cloud and AI Infrastructure

Oracle began in 1977 in a 900-square-foot office. Its original strength was relational database software, the technology companies use to organise, retrieve and protect critical information.

Over the following decades Oracle assembled a much wider technology stack through acquisitions including PeopleSoft, Sun Microsystems, NetSuite and Cerner. Oracle says it has spent more than $110 billion on over 150 acquisitions.

It can now sell almost every layer of a large organisation's technology system:

• The physical servers and engineered systems
• The cloud infrastructure that supplies computing power
• The database that stores and manages information
• The applications that run finance, payroll, supply chains and hospitals
• The consultants who help install and operate those systems

This breadth also makes the business easy to misunderstand. A database customer may appear in cloud, licence or support revenue depending on how the product is deployed. Oracle's products and its accounting revenue lines are not the same thing.

How Oracle Makes Money: The Four-Engine Model for Understanding Oracle

A simpler way to understand Oracle is to focus on the economic job performed by each part of the company.

The model explains Oracle's current tension. The toll road and rental suite are attractive because software can be sold repeatedly without rebuilding the product for every customer. The power station can grow much faster, but each new unit of capacity requires data centres, chips, networking equipment and electricity.

That is why Oracle's revenue is accelerating while its free cash flow is falling.

Oracle Revenue Breakdown: How Much Does Each Business Make?

Oracle generated $67.36 billion in FY2026 revenue, up 17% from the previous year. Cloud became the largest broad revenue category, but software support remained the company's largest individual offering.

Source: Oracle FY2026 Form 10-K. Revenue shares and growth rates calculated from company data.

The table exposes three different versions of Oracle.

Software support is the largest individual revenue source. It barely grows, but its stability helps fund the rest of the company. Cloud applications are the steady compounding business. OCI is the growth engine, having expanded from $10.23 billion to $18.10 billion in one year.

Traditional software licence revenue is shrinking as more customers choose subscriptions or cloud deployment. That decline is not automatically customer loss. In many cases Oracle is moving the same workload from an upfront licence model into recurring cloud revenue.

How Oracle Database Makes Money: Licences, Support and Cloud

Oracle Database is the centre of the company's economic ecosystem, but Oracle does not report “database revenue” as a separate line.

The same core product can make money through three routes.

1. Upfront software licences

A business can purchase a licence to run Oracle Database or related software in its own data centre or another IT environment. Oracle generally recognises this revenue when the software is made available to the customer.

Licence sales can be lumpy because major contracts do not arrive evenly every quarter.

2. Recurring software support

After buying a licence, customers often pay for technical support, security fixes, upgrades and product enhancements. These contracts are generally billed in advance and recognised as revenue over the support period.

Support is the quiet giant inside Oracle. It generated $19.80 billion in FY2026, more than four times the $4.74 billion earned from new software licences. About 81% of Oracle's total software revenue came from support.

The reason is simple. Databases often sit underneath billing systems, bank records, payroll, airline reservations and government workloads. Replacing one is closer to changing the foundation of a building than swapping a phone app. The cost, operational risk and possible downtime create high switching barriers.

3. Cloud database consumption

Customers can also run Oracle databases on OCI or through Oracle's database services inside Microsoft Azure, Amazon Web Services and Google Cloud environments. Oracle then earns recurring cloud revenue as the customer consumes database capacity.

This multicloud model lets Oracle take its database to the cloud where a customer already runs other applications, without first moving the customer's entire technology estate to OCI.

Oracle's multicloud revenue grew 404% in Q4 FY2026, although the company did not disclose its absolute size. The percentage is impressive, but investors should not treat it as proof that multicloud is already a major revenue line without the starting value.

Our view is that the database acts as Oracle's gravity well. Once critical data sits inside Oracle, the company has several opportunities to sell support, cloud infrastructure, analytics, security and business applications around it.

How Oracle Cloud Applications Make Money

Oracle's cloud applications business generated $15.89 billion in FY2026 revenue, up 11%.

The portfolio includes Fusion for finance, planning, human resources and supply chains, NetSuite for smaller businesses, Oracle Health and industry products for sectors such as banking, retail, utilities, hospitality and government.

Customers typically pay recurring subscription fees over a contract term. Revenue is recognised over time as Oracle provides access, updates and support.

These products are sticky for the same reason the database is sticky. Once a company runs its payroll, financial close or hospital records on a platform, moving away requires data migration, staff retraining, process redesign and regulatory checks.

Oracle is also adding AI agents into its applications. Many core AI features are included without a separate charge, which can improve retention and protect pricing. Oracle is also testing paid token bundles and outcome-based pricing, such as charging for the number of candidates screened by a recruiting agent.

The application subscription provides the installed base, while advanced AI usage could create incremental consumption revenue.

Oracle Health deserves attention because Cerner was acquired for approximately $28.3 billion. However, Oracle does not disclose its standalone revenue or profit. Any precise claim about Cerner's profitability would therefore be an estimate.

How Oracle Cloud Infrastructure (OCI) Makes Money

Oracle Cloud Infrastructure, or OCI, rents computing resources to businesses, governments and AI companies.

Customers pay for products such as:

• CPU and GPU computing capacity
• Data storage and transfer
• Networking and security
• Cloud databases and Exadata systems
• AI model training and inference
• Dedicated cloud regions and Cloud@Customer deployments

Some customers pay based on usage. Others sign large multi-year capacity contracts. In certain large AI contracts, customers either prepay Oracle for GPUs or buy the GPUs and supply them to Oracle.

OCI generated $18.10 billion in FY2026 revenue, up 77%. Growth accelerated through the year and reached 93% in Q4, when quarterly OCI revenue hit $5.79 billion.

Management also disclosed a 97.5% global GPU utilisation rate in Q4. Of 35,000 GPUs coming up for renewal, customers renewed 92% of the capacity and Oracle said much of the remaining capacity was resold to other customers during the same quarter.

That matters because a GPU only earns money while a customer is using it. High utilisation improves the economics of an expensive asset and makes it easier to reallocate capacity if one customer's needs change.

However, OCI has completely altered Oracle's capital requirements. Software code can be sold repeatedly. A GPU cluster cannot. Oracle must buy equipment, secure power, lease data centre space and connect each site before it can recognise the contracted revenue.

Management believes OCI can eventually achieve a 30% to 40% margin profile. That is a long-term target, not a separately reported FY2026 result. Near-term margins are under pressure because new data centres incur costs before reaching full contracted utilisation.

Software Support Is Still Oracle's Cash Cow

OCI receives most of the attention, but software support remains Oracle's financial anchor.

Revenue stayed almost flat at approximately $19.5 billion to $19.8 billion across FY2024, FY2025 and FY2026. That lack of growth can look dull. Economically, it is extremely useful.

Support contracts are commonly billed in advance, require far less physical capital than AI data centres and benefit from an installed base running mission-critical systems. This combination makes software support the strongest candidate for Oracle's largest source of recurring cash generation.

That last statement is an inference, not a disclosed segment cash-flow figure. Oracle does not report cash flow by product. Still, the scale, recurrence and limited capital needs of support make the conclusion reasonable.

The old database business is therefore not dead weight. It is the internal financing engine behind Oracle's cloud transformation.

Oracle Hardware and Services: How They Fit Into the Business Model

Hardware and services together produced 13.1% of Oracle's FY2026 revenue. The hardware business sells engineered systems such as Exadata, servers, storage products, operating systems and related support. Hardware generated $3.08 billion in revenue, up 5%. The services business provides consulting and customer success work. It generated $5.74 billion, up 10%.

Neither business decides Oracle's overall growth rate. Their value is partly strategic. Hardware lets Oracle optimise databases, operating systems and equipment together. Services help customers complete difficult implementations. Both can protect or pull through more valuable cloud and software revenue.

Services is also Oracle's lowest-margin reported business. That is common in consulting because revenue depends heavily on skilled employees and external contractors. A software subscription can be delivered to another customer at low incremental cost. A consulting project usually needs more people and more hours.

Which Oracle Business Is Driving the Most Growth?

Oracle added $9.96 billion of revenue in FY2026. OCI supplied most of it.

Source: Oracle FY2026 Form 10-K. Contributions calculated from company data and may not total exactly because of rounding.

Total cloud revenue contributed about 95% of Oracle's growth. OCI alone contributed 79%.

This is the single most important number in Oracle's business model. The company is no longer growing mainly because old database customers pay slightly more each year. It is growing because OCI is adding an infrastructure business at an enormous scale.

The trade-off is that the business responsible for most of the growth is also responsible for most of the new capital intensity.

Which Oracle Business Generates the Most Profit?

Oracle reports three operating businesses: cloud and software, hardware and services. All three produced a positive segment margin in FY2026.

Source: Oracle FY2026 Form 10-K. Margin rates and contributions calculated from company data.

These are not fully loaded operating profits. Oracle's segment margin excludes R&D, general and administrative costs, intangible amortisation, restructuring, stock-based compensation, interest expense and certain other items.

Cloud and software is still the dominant profit engine, producing more than 90% of total segment margin. Hardware's 65% margin includes equipment and higher-margin support. Services earned the lowest margin at about 27%.

After corporate and shared costs, Oracle reported $20.61 billion of GAAP operating income and a 30.6% operating margin.

Does Oracle Have Any Loss-Making Business Segments?

There is no reported loss-making Oracle segment in FY2026. That is the honest answer.

Services had the lowest segment margin, but it still earned $1.53 billion before unallocated expenses. Hardware also produced a positive margin. Cloud and software was highly profitable on the reported measure.

Oracle does not separately disclose operating profit for OCI, cloud applications, the database business, NetSuite or Oracle Health. It is therefore not possible to identify a product-level loser using audited segment data.

The closest answer depends on what investors mean by “losing money”:

• Lowest reported margin: Services at 26.7%
• Largest near-term cash consumer: OCI's data centre buildout
• Largest product-level transparency gap: Oracle Health and OCI profitability
• Largest declining revenue stream: Software licences, down 8.9%

OCI may be generating a positive operating contribution from capacity already in service while still consuming huge amounts of cash to build future capacity. Profit and cash burn can exist in the same business at the same time.

Why Is Oracle Free Cash Flow Negative Despite Record Profits?

Oracle's cash-flow transformation has been dramatic.

Source: Oracle annual reports and FY2026 earnings release.

Operating cash flow grew 54% in FY2026. That is excellent. Capital expenditure grew even faster, rising 162% to $55.66 billion. Oracle spent $1.74 on capital expenditure for every $1 generated from operations.

Think of a taxi company that buys an entire fleet today but records the cost of each car gradually over its useful life. Cash leaves immediately. The income statement only records annual depreciation.

Oracle's data centres work in a similar way. The company pays upfront for buildings, GPUs and networking equipment. Those assets then become depreciation expense over several years. This timing difference allows Oracle to report $17.09 billion of net income while producing negative $23.69 billion of free cash flow.

Why Is Oracle's Debt Rising So Fast?

Oracle has used debt for acquisitions and shareholder returns in the past. The Cerner acquisition added a large funding requirement in 2022. The latest increase, however, is mainly connected to AI and cloud infrastructure.

Oracle raised $43 billion of debt and about $5 billion of equity financing in FY2026. Borrowings, excluding recorded lease liabilities, ended the year at approximately $129.5 billion, up from $92.6 billion a year earlier.

Source: Oracle FY2026 Form 10-K. Borrowings calculated from reported short-term borrowings, current maturities and long-term debt.

The $260 billion lease commitment is not the same as current bank or bond debt and should not simply be added to borrowings as if every dollar were due today. The commitments generally start between FY2027 and FY2029 and run for 15 to 19 years.

Still, they are long-duration fixed obligations. Oracle is matching contracts with AI customers against leases that can last close to two decades. That makes the quality and longevity of customer demand central to the balance-sheet story.

The biggest risk is not that Oracle suddenly cannot pay next year's bond maturity. The bigger risk is that it builds capacity for a long-term contract, the customer weakens or technology changes and Oracle must find a replacement user at a lower price.

Can Oracle Afford Its Debt and AI Infrastructure Spending?

Yes for today's interest bill. Not yet for the full infrastructure plan without outside financing. Those are two different tests.

Test 1: Can current profits cover interest?

Oracle generated $20.61 billion of FY2026 operating income against $4.60 billion of interest expense.

Interest coverage = Operating income ÷ Interest expense

$20.61B ÷ $4.60B = 4.5 times

Interest consumed about 22 cents of every dollar of operating profit. That is material, but current earnings still provide a reasonable cushion.

Operating cash flow covered interest roughly 7 times. Even after removing the $4.59 billion customer prepayment with a significant financing component, adjusted operating cash flow would cover interest about 6 times.

Oracle also held $31.9 billion of cash and short-term investments against roughly $7.2 billion of borrowings due within a year. Near-term liquidity is therefore not the main concern.

Test 2: Can Oracle self-fund the AI buildout?

No, not at the current spending rate.

FY2026 operating cash flow fell $23.69 billion short of capital expenditure. After $5.79 billion of dividends, the gap was roughly $29.5 billion before considering other financing and investing flows.

For FY2027, management expects a net cash outlay for capital expenditure of about $70 billion. Reported capex could be $90 billion to $95 billion before customer prepayments and timing-related financing effects. Oracle expects to raise around $40 billion through debt and equity, including an already announced $20 billion at-the-market equity programme.

A simple FY2027 funding model

Oracle has guided to $90 billion of FY2027 revenue. It has not provided operating cash flow guidance, so the following is an illustration rather than a forecast.

The model explains why management's financing plan is close to $40 billion. Oracle's core operations can pay interest and fund a large part of the buildout, but they cannot yet cover the full combination of capex and dividends.

The business is serviceable today. The investment programme is not self-funding today. Oracle needs contracted revenue to convert into cash before the financing burden becomes structurally comfortable.

This risk is visible in the bond market. In July 2026 S&P Global Ratings downgraded Oracle's long-term issuer rating from BBB to BBB-, one notch above speculative grade, while maintaining a stable outlook.

Is Oracle's $638 Billion Backlog Real Protection?

Oracle ended FY2026 with $638 billion of remaining performance obligations, or RPO, up 363% year on year.

RPO is contracted revenue that has not yet been recognised. It provides visibility, but it is not the same as cash in the bank and it is not profit.

The backlog was about 9.5 times Oracle's FY2026 revenue. Management expects to recognise 12% within the next 12 months and another 34% during months 13 to 36. That equals approximately $76.6 billion and $216.9 billion respectively.

Three facts improve the backlog's quality:

1. Many contracts are long term, which improves revenue visibility.
2. Prepaid or customer-supplied hardware connected with large AI contracts totalled $75 billion.
3. Oracle can reassign standardised GPU capacity. Its 97.5% utilisation suggests alternative demand currently exists.

Three risks remain:

1. Revenue can be delayed if Oracle cannot deliver data centre capacity on time.
2. Backlog does not reveal the margin earned on each contract.
3. Customer concentration is high. S&P estimated that OpenAI represented roughly half of Oracle's RPO.

Customer prepayments and supplied GPUs reduce upfront capital risk, but concentration increases counterparty risk. Oracle is safer when customers fund equipment, but less safe when too much future revenue depends on a small group.

Our view is that RPO should be treated as contractual visibility, not as guaranteed economic value. Investors must ask what return Oracle earns after depreciation, electricity, interest and the cost of long-term leases.

Oracle's Headline Earnings Need One Adjustment

Oracle reported FY2026 GAAP net income of $17.09 billion, up 37%.

Part of that increase came from $3.55 billion of net non-operating income, compared with only $60 million in FY2025. Oracle's reported non-GAAP EPS was $7.63, but the company said it would have been $6.83 after excluding one-time investment gains from transactions involving Ampere and Bloom Energy.

That is a difference of about 12%.

For analysing the operating business, investors should focus on revenue growth, operating income, interest expense, operating cash flow and capital expenditure. Headline net income benefited from gains that will not recur every year.

Oracle (ORCL) Stock Valuation: How Should Investors Value the New Oracle?

At the September 4, 2026 close of $158.78, Oracle had a market value of approximately $457 billion. The shares had fallen about 29% over the previous 52 weeks as investors reassessed the cost and financing risk of the AI buildout.

Using management's FY2027 non-GAAP EPS guidance of $8.05, Oracle stock traded at approximately 19.7 times guided earnings. The $90 billion revenue forecast put its market value at about 5.1 times forward sales. Including borrowings and recorded lease liabilities produces an enterprise value closer to 6.6 times guided revenue.

The valuation can look reasonable against 34% guided revenue growth, 18% adjusted EPS growth and the $638 billion backlog. It looks less comfortable against negative free cash flow, a credit rating one step above junk, dilution and long-term lease commitments.

The planned $20 billion at-the-market equity issuance also matters. At $158.78 per share, raising the entire amount at that price would require about 126 million new shares, equal to roughly 4.4% of Oracle's current share count. The actual dilution will depend on issuance prices, timing and the amount ultimately sold.

Oracle is shifting from an asset-light licence and support model towards a blended software and infrastructure model. The market should not value all of Oracle like a utility because its software assets still produce powerful recurring economics. It should not value all of Oracle like pure software either because OCI now requires vast physical investment.

The right question is not simply whether Oracle's revenue grows. It is whether the new OCI revenue earns a return above the cost of debt, leases and equity used to build it.

Oracle Business Model Scorecard

What Should Oracle Investors Track Next?

1. OCI revenue relative to capital expenditure: OCI growth is not enough by itself. Investors should track how much incremental revenue and operating cash flow Oracle produces for every dollar of new infrastructure spending.

2. Infrastructure margins: Management has outlined a 30% to 40% long-term OCI margin profile. Progress towards that range matters more than revenue growth alone. Depreciation and lease costs will rise as new data centres enter service.

3. Backlog conversion: Oracle expects $76.6 billion of current RPO to become revenue within 12 months. Delays in site completion, power availability, chips or customer deployment could slow conversion.

4. Customer concentration and prepayments: Investors should watch whether new RPO comes from a broader customer set and whether customers continue to prepay or provide GPUs. Diversification reduces the damage caused by any one customer's financial problems.

5. Debt, interest and credit ratings: Interest expense grew 29% in FY2026. Operating income must continue growing faster than financing costs. A further rating downgrade could raise the price of future borrowing.

6. Share dilution: Oracle is no longer using surplus cash to shrink its share count aggressively. Equity issuance can protect the balance sheet, but it also spreads future earnings across more shares.

7. The health of the old cash engine: Software support revenue must remain stable while cloud applications continue double-digit growth. If the legacy cash engine weakens before OCI becomes self-funding, Oracle's financial flexibility would narrow.

8. Oracle Health and multicloud database growth: Both could become meaningful second-order growth drivers. Investors should look for absolute revenue or margin disclosures rather than relying only on large percentage growth rates or product announcements.

Our Take: Oracle Has Traded Predictability for Possibility

Oracle's transformation is more radical than it first appears.

The company spent decades building one of technology's best toll-road businesses. Databases and support contracts produced sticky, recurring revenue with modest capital needs. Oracle is now using that advantage to finance an AI infrastructure business that requires enormous upfront investment.

The strategy is logical. OCI contributed 79% of FY2026 revenue growth, GPU utilisation was 97.5% and contracted demand reached $638 billion. Oracle's database relationships also give it a differentiated route into enterprise AI because businesses want to run models against valuable private data.

But the financial risk is equally real. Free cash flow was negative $23.7 billion, borrowings reached $129.5 billion and $260 billion of additional lease commitments had not yet entered the balance sheet. S&P's downgrade to BBB- shows that the debt question is no longer theoretical.

Our assessment is that Oracle has enough business quality to service its current debt, but not enough current cash generation to fund its planned expansion without more debt, customer financing or dilution. That makes the next stage of the story an execution test rather than a demand test. Demand already appears extraordinary. The unresolved question is capital productivity.

If Oracle converts backlog on schedule, lifts OCI towards its targeted margin profile and brings free cash flow back into positive territory, the company could emerge with three reinforcing assets: the database moat, a large enterprise application base and a scaled AI infrastructure network.

If conversion is delayed or major customers weaken, Oracle could be left paying interest and long-term leases on technology that loses value faster than the contracts mature.

That is the central Oracle investment debate. The old software business is still paying the bills. OCI is deciding how large Oracle can become and how much financial risk shareholders must accept to get there.
