Amazon and Microsoft are leveraging artificial intelligence to drive significant revenue growth, outpacing broader market indices. While the S&P 500 has delivered a 10.7% compound annual return since 1957, both tech giants have generated substantially higher returns since their initial public offerings. Amazon’s stock has risen 338,180% since 1997, translating to a 32.3% annualized return, while Microsoft’s shares have climbed 676,310% since 1986, equating to a 24.7% annualized gain.
According to Yahoo Finance, these companies are positioned to capitalize on the next phase of AI adoption. Amazon’s Amazon Web Services (AWS) division reported a 37% revenue increase in the second quarter, contributing $148 billion over the last four quarters. Microsoft has expanded its enterprise footprint, with 30 million paid licenses for Copilot for 365 as of June 30, representing a 50% increase from March 31.
AWS Drives Cloud Revenue Expansion
Amazon’s cloud infrastructure remains central to its AI strategy, operating data centers equipped with thousands of specialized chips from suppliers like Nvidia and its in-house Trainium3 processors. The company’s chip business alone generates over $25 billion in annualized revenue. AWS Bedrock provides developers access to hundreds of third-party models, while the AI coding assistant Kiro saw usage triple sequentially during the second quarter of 2026.
CEO Andy Jassy projects AWS could eventually reach $1 trillion in annual revenue, supported by a current order backlog of $496 billion as customers await additional data center capacity. The business is currently valued at a forward price-to-earnings ratio of 24.4 based on 2027 estimates, which aligns closely with the Nasdaq-100 index forward P/E of 24.2.
Microsoft Enterprise Adoption Accelerates
Microsoft has embedded its Copilot assistant into legacy products such as Windows, Bing, and Edge at no cost to users. For enterprise clients, Copilot for 365 is available as a paid subscription add-on, integrating AI capabilities into Word, Excel, PowerPoint, and Outlook to accelerate productivity workflows.
The rapid uptake of these enterprise licenses indicates strong demand for integrated AI tools within established productivity suites. The 50% quarterly growth in paid licenses suggests a shift from experimental adoption to standardized corporate deployment, reinforcing the company’s position in the enterprise software market.
