Oracle makes money by renting software and computing power to large organizations. A hospital uses Oracle to manage patient records. A retailer uses it to track supply chains. A government agency uses it to run payroll. These customers sign contracts, typically one to five years long, and pay Oracle every year to keep the lights on. The company earns revenue three main ways: cloud subscriptions (customers pay to use software Oracle hosts and manages), software support fees (customers pay a yearly charge to keep their existing software updated), and hardware sales paired with support contracts. Cloud revenue has grown fast enough that it crossed 51% of total revenue in fiscal 2026, overtaking the older software businesses for the first time. The diagram below traces where the money goes.

Five years of financial data tell a clear story about direction. Revenue climbed from $42.4 billion in fiscal 2022 to $67.4 billion in fiscal 2026, a gain of nearly $25 billion. That is not a sudden spike. It is a steady annual march upward, which suggests the demand is real and repeating, not a one-time event.

Cash from operations followed the same upward path, rising from $9.5 billion in fiscal 2022 to $32.0 billion in fiscal 2026. That is the clearest sign of a healthy subscription business: cash keeps arriving before costs are fully paid, because customers pay upfront for services they will use over the coming year. However, free cash flow, which is cash from operations after spending on physical assets, tells a different story. It swung from positive $11.8 billion in fiscal 2024 to negative $23.7 billion in fiscal 2026. That is not a sign the business is collapsing. It is a sign the company is spending enormous sums building data centers to house the cloud infrastructure its customers are demanding.

Oracle spent $10.3 billion on research and development in fiscal 2026 alone, up from $8.9 billion in fiscal 2024. That is the cost of keeping Oracle products competitive in a world where cloud rivals spend just as aggressively. The cloud infrastructure segment, called Oracle Cloud Infrastructure or OCI, grew 77% in fiscal 2026 compared to fiscal 2025. That growth rate is what is pulling the capital spending higher.

There is a structural cushion built into this business that protects it during slow periods. Software support contracts, the annual fees customers pay to keep their existing Oracle software running, generated $19.8 billion in fiscal 2026. Virtually all customers renew these contracts every year. That revenue does not grow fast, but it does not disappear fast either. It acts like a floor under the whole business.

The risks Oracle faces are specific and documented. The first involves artificial intelligence. Oracle has built AI features into its database and cloud products, but the company openly warns that those AI tools might not perform as well as customers expect, or might not keep up with competitors' AI products. If customers try Oracle's AI tools and decide a rival's version is better, Oracle could lose contracts and damage its reputation for being a reliable technology partner.

The second risk is about the cost of building the cloud. Oracle has signed long-term contracts with data center providers and energy suppliers to secure the capacity it needs. Those contracts require Oracle to keep paying even if customer demand comes in lower than expected. Energy costs and power shortages are called out specifically as threats to profit margins. This is not a hypothetical. The free cash flow turning deeply negative in fiscal 2026 reflects exactly this kind of heavy upfront commitment.

Supply chain is a third specific threat. Oracle depends on graphics processing units, a type of chip used heavily for AI workloads, from suppliers where there is sometimes only one source available. Trade disputes, tariffs, and shortages have already forced Oracle to buy more inventory at higher prices. If those chips become unavailable or too expensive, Oracle cannot build the infrastructure its customers are paying for.

Regulation adds another layer of uncertainty. Governments in the European Union and the United States are writing new rules for AI. Those rules are described in Oracle's filings as conflicting and constantly changing. Compliance could require Oracle to redesign products for specific regions or pull back from certain markets entirely. Privacy laws like the EU's General Data Protection Regulation already impose fines of up to 4% of worldwide revenue for violations, and enforcement is growing stricter.
