Amazon vs. Alphabet vs. Microsoft Cloud: 2 Buy, 1 Sell – Which Hyperscalers Impress

Key Takeaways

• Microsoft lost around 20 percent in market value through mid-2026, while Alphabet gained 13 percent and Amazon 7 percent (as of July 12, 2026)
• AWS increased revenue growth from 28 percent in the first to 37 percent in the second quarter of 2026 – the highest rate in 18 quarters
• Microsoft Azure broke through the $100 billion revenue mark for the first time in fiscal year 2026 and grew 43 percent in the fourth fiscal quarter
• Amazon operates a custom-chip business for AI accelerators with a run rate exceeding $20 billion, including internal use totaling $50 billion
• Analysts favored Amazon and Alphabet over Microsoft in early September 2026 due to stronger growth acceleration and market share gains in cloud business

Diverging Stock Performance in the First Half of 2026

The first half of 2026 painted an unexpected picture in the battle among cloud giants. While Alphabet topped the leaderboard with a gain of 13 percent, Amazon gained around 7 percent. Microsoft, by contrast, lost 20 percent in market value – a striking deviation for a technology stock amid the ongoing AI boom (as of July 12, 2026). Amazon was trading at $245.23 at that time with a market capitalization of $2.6 trillion and a forward P/E ratio below 25 for fiscal year 2027.

The diverging stock performance does not necessarily reflect the operational performance of the cloud divisions. All three companies recorded strong growth in cloud business, though the pace and market position developed differently.

AWS Accelerates to 18-Quarter High

Amazon Web Services (AWS) – Amazon's cloud infrastructure division and still the global market leader – showed significant growth acceleration during the year. In the first quarter of 2026, revenue rose 28 percent year-over-year. In the second quarter of 2026, AWS achieved revenue growth of 37 percent – the highest rate in 18 quarters, as Amazon reported on August 3, 2026.

AWS is Amazon's most profitable business segment, although the company is primarily perceived externally as an e-commerce firm. While the gap to competitors Google Cloud and Microsoft Azure is narrowing, AWS continues to defend its leadership position in the Infrastructure-as-a-Service segment – the operation of data centers, storage, and network infrastructure for enterprise customers.

Azure Breaks Through $100 Billion Milestone

Microsoft Azure, the cloud platform of the software company, achieved annual revenue exceeding $100 billion for the first time in fiscal year 2026 (ending June 30, 2026) – a symbolically important milestone announced on August 6, 2026. In the fourth quarter of fiscal year 2026, Azure revenue climbed 43 percent year-over-year, as Microsoft reported on August 1, 2026.

Azure had already recorded eleven consecutive quarters of growth of at least 30 percent at that time (as of July 12, 2026). CFO Amy Hood had already announced on February 12, 2026, that capital expenditures (capex) in fiscal year 2026 would exceed the prior year level – driven by accelerated demand and growing Remaining Performance Obligations, or future revenues already contractually committed. For the first quarter of the new fiscal year, Microsoft planned capital expenditures of $50 billion, primarily for cloud and AI infrastructure expansion.

Google Cloud Catches Up with AI-Driven Momentum

Google Cloud, the third-largest public cloud platform, also benefited from rising demand for AI infrastructure. Alphabet recorded robust cloud growth, driven by demand for AI applications, as communicated on August 6, 2026. The market share gap to AWS and Microsoft narrowed during the year.

Unlike Microsoft and Amazon, Alphabet offers a vertically integrated AI architecture: its own AI models from the Gemini family and self-developed Tensor Processing Units (TPUs) – specialized chips for machine learning. This combination lowers operating costs and gives Google Cloud a competitive advantage over providers reliant on external AI models or standard chips.

AI Infrastructure as Growth Driver and Differentiator

All three companies are investing heavily in artificial intelligence, but pursuing different strategies. Amazon relies on partnerships with Anthropic and OpenAI and operates an extensive custom-chip business. The in-house AI accelerators and CPUs reached a run rate exceeding $20 billion; including internal use within the Amazon group, even $50 billion. These proprietary developments significantly lower inference costs – the compute costs for running trained AI models. Additionally, the e-commerce business benefits from robotics and AI investments in logistics and recommendation systems.

Microsoft positions Azure as the central growth platform for its enterprise software business. Critics, however, note that Microsoft relies more heavily on external AI models and less on proprietary development – a potential strategic disadvantage versus Alphabet.

Alphabet offers an end-to-end integrated AI solution with Gemini models and TPUs. Analysts highlight this vertical integration as a structural advantage over competitors' approaches.

Analyst Verdict: Two Buys, One Sell

In early September 2026, analysts favored Amazon and Alphabet despite Microsoft's lower valuation. The reasons were superior growth acceleration and market share gains at AWS and Google Cloud. Both platforms showed rapid acceleration, positioning them favorably for the ongoing AI race.

Microsoft, despite impressive absolute numbers at Azure, lags in comparison – not due to insufficient growth, but because of slower acceleration pace and strategic dependence on third-party AI. The stock performance in the first half of 2026 likely already partially reflected this assessment.

For investors in the DACH region, the choice among the three hyperscalers remains a question of strategic priorities: AWS offers market leadership and operational strength, Google Cloud technological integration, and Microsoft Azure the closest integration with the enterprise software ecosystem. Current market sentiment favors growth dynamics and proprietary AI technology – and thus Amazon and Alphabet.
