Amazon’s third-quarter earnings have put its cloud business firmly in the spotlight. The company reported $201.9 billion in revenue for the quarter, up 12% from $180.2 billion a year earlier. Meanwhile, operating income climbed to $28.1 billion from $17.4 billion.
The bigger story was Amazon Web Services (AWS). Its revenue surged approximately 39% to $46 billion. This marks one of its strongest growth periods in years and highlights the enormous demand for cloud computing infrastructure.
Artificial intelligence is playing an increasingly important role in that expansion. Businesses are investing in advanced AI models, enterprise applications and the computing resources needed to support them. Amazon is responding with substantial infrastructure investments, although those commitments are placing considerable pressure on its cash flow.
AWS Revenue Jumps 39% as AI Infrastructure Demand Accelerates
Amazon Web Services recorded approximately $46 billion in third-quarter revenue, compared with roughly $33 billion during the same period in 2025. The increase represents growth of about 39%, an impressive result for a cloud business already operating at considerable scale. In addition, AWS also generated $17.8 billion in operating income, up from $11.4 billion a year earlier. This reinforces its position as one of Amazon’s most profitable divisions.
Demand for artificial intelligence infrastructure has become an important driver of cloud expansion. Companies developing generative AI tools, training machine learning models and integrating AI into business operations need access to powerful computing systems. Rather than building and maintaining their own facilities, many organizations rely on cloud providers such as AWS to supply those resources. As a result, the acceleration in AWS revenue suggests that enterprise spending on cloud services remains strong. Businesses are expanding their use of AI.
Amazon Increases Infrastructure Spending to Support AI Expansion
Amazon is spending heavily to expand the computing infrastructure supporting its cloud business and other operations. During the third quarter, purchases of property and equipment reached approximately $77.3 billion, compared with $35.1 billion a year earlier. The increase reflects the scale of Amazon’s investment in data centers, computing equipment and the facilities required to support growing demand.
Building infrastructure for artificial intelligence is particularly expensive because advanced AI systems require substantial processing power, specialized hardware and reliable networking capacity. Therefore, Amazon must continue expanding these resources while ensuring that existing customers receive consistent service. The company is effectively investing ahead of anticipated demand. It expects businesses to continue increasing their spending on cloud computing and AI applications.
Those investments are also affecting Amazon’s financial position. Free cash flow over the trailing 12 months fell to negative $42.4 billion, compared with positive $14.8 billion during the previous comparable period. Although Amazon remains profitable at the operating level, the figures illustrate how its aggressive infrastructure expansion is consuming substantial cash.
AWS Accounts for a Major Share of Amazon’s Operating Profit
Amazon’s retail operations generate the largest portion of its total revenue, but AWS continues to contribute a significant share of the company’s profitability. During the third quarter, AWS produced approximately $17.8 billion in operating income, representing around 63% of Amazon’s total operating income of $28.1 billion. Moreover, the cloud division’s operating margin also improved to approximately 38.7%, compared with 34.6% a year earlier.
This performance helps explain why Amazon continues prioritizing cloud infrastructure investment despite the enormous costs involved. AWS serves businesses across industries that depend on cloud storage, computing, cybersecurity, analytics and increasingly sophisticated AI applications. As demand grows, Amazon has an opportunity to generate additional revenue from customers expanding their technology operations. Maintaining that growth, however, requires the company to balance infrastructure spending with operational efficiency.
Amazon’s Retail and Advertising Businesses Continue to Grow
While AWS delivered the strongest growth, Amazon’s other business segments also contributed to its quarterly performance. North American sales reached approximately $112.9 billion, increasing 6% year over year. Moreover, international revenue climbed 5% to $43.1 billion. These figures demonstrate the continued scale of Amazon’s retail operations. Cloud computing is becoming a more prominent part of its overall business strategy.
Amazon’s advertising business also recorded growth, generating approximately $19.6 billion in quarterly revenue, up 11% from the previous year. Advertising provides another source of income through Amazon’s retail ecosystem and digital services. This allows brands and merchants to reach customers across its platforms. The company continues integrating technology and automation into its broader operations, creating opportunities to improve efficiency and customer experiences across retail, logistics and advertising.
Amazon Faces Growing Competition From Microsoft and Google in AI Cloud Services
The rapid expansion of AWS comes as competition among major cloud providers intensifies. Microsoft Azure and Google Cloud are also investing heavily in artificial intelligence infrastructure, seeking to attract businesses developing and deploying AI applications. These companies are competing not only on computing capacity but also on the availability of AI tools, developer services and enterprise technology platforms.
For Amazon, maintaining its position in the cloud market requires continued investment in infrastructure and services capable of handling increasingly demanding workloads. Enterprise customers expect reliable computing resources, strong security and the flexibility to deploy AI systems at scale. AWS’s substantial revenue growth indicates that demand remains healthy. However, competition is likely to increase as more organizations move beyond AI experimentation and begin implementing the technology across their operations.
Amazon Expects Revenue Growth to Continue in the Fourth Quarter
Amazon expects its financial momentum to continue during the final quarter of 2026. The company forecasts net sales between $240 billion and $247 billion, representing anticipated growth of approximately 12% to 16% compared with the fourth quarter of 2025. Operating income is projected to range from $28.5 billion to $33.5 billion, compared with $25 billion during the same period last year.
The outlook reflects expectations for continued business activity across Amazon’s operations, including seasonal retail demand and the expanding contribution of cloud computing. AWS will remain particularly important as businesses increase their use of AI infrastructure and cloud-based services. Besides, investors will also be watching how Amazon manages the financial impact of its infrastructure investments, especially as spending on data centers and computing equipment continues at a significant pace.
Amazon’s Earnings Show How AI Is Reshaping the Cloud Computing Market
Amazon’s third-quarter performance highlights how artificial intelligence is influencing the economics of cloud computing. AWS’s 39% revenue growth demonstrates that demand for computing infrastructure is translating into substantial business opportunities, particularly as organizations invest in deploying AI applications at commercial scale.
The financial results also reveal the costs associated with meeting that demand. Amazon is committing enormous resources to infrastructure expansion, placing pressure on free cash flow even as its operating income improves. The company is betting that sustained demand for AI computing will eventually justify those investments through higher cloud revenue and long-term profitability.
For the broader technology industry, Amazon’s results illustrate a shift in how the AI economy is developing. Building advanced AI models remains important, but providing the infrastructure needed to operate those systems is becoming an equally significant business. Amazon’s latest earnings suggest that this demand is already producing measurable growth. However, the long-term returns on today’s infrastructure spending remain an important question.
