The August 2026 earnings cycle delivered a clear message: the three US hyperscalers are converting massive AI infrastructure spend into accelerating cloud revenue alongside record capex. Azure grew 43% in Q4 FY2026, AWS posted its fastest growth in 18 quarters at 36.7%, and Google Cloud accelerated to 82% year-over-year. Backlogs at all three ballooned, suggesting the revenue tailwind extends well into 2027. For investors positioning after the earnings reports, these are the three cloud names worth a closer look this month.
Microsoft (MSFT): The Backlog Story Wall Street Is Underestimating
Microsoft (NASDAQ:MSFT | MSFT Price Prediction) trades at $496.88 with a P/E of 28 and a market cap near $3.69 trillion. The stock is up 29.08% over the past month after the July 29 earnings report, but only 3.2% year to date.
Q4 revenue landed at $90 billion, up 18%, with EPS of $4.74. Azure crossed $100 billion in full-year revenue for the first time, and management guided Q1 FY27 Azure growth to approximately 45% in constant currency. The standout figure is commercial remaining performance obligation of $678 billion, up 84%. As CFO Amy Hood put it, “All sequential commercial RPO growth was driven by commitments from customers outside of frontier model companies. And RPO increased 25% when excluding OpenAI.” That’s a genuine, diversified enterprise book.
Bull case: With 30 million paid Microsoft 365 Copilot seats and analyst consensus at 95% bullish with a $567.20 target, Microsoft is scaling AI monetization faster than peers can match. Risk: Calendar-year 2026 capex is now guided to approximately $175 billion. If AI demand cools, free cash flow (already -23.19% YoY in Q4) stays pressured.
Amazon (AMZN): AWS Growth Is Re-Accelerating
Amazon (NASDAQ:AMZN) sits at $265.13, up 14.86% year to date and 18.07% over the past year. The P/E of 37 looks rich until you unpack the segment math.
AWS delivered $42.2 billion in Q2 revenue, up 36.7% year over year, with an operating margin of 39% and operating income of $16.6 billion. The segment is now at a $169 billion annualized run rate with a backlog of $496 billion. AI and Chips businesses each cleared $25 billion run rates growing triple digits, powered by Trainium wins with Anthropic and OpenAI plus Graviton adoption at 98% of the top 1,000 EC2 customers.
CEO Andy Jassy went further than usual on the long-term math: “We long believed AWS could become a few hundred billion dollar revenue business and now believe it will be at least double that and very possibly be a trillion dollar annual revenue business for us in time.”
Bull case: Q3 guidance of $197 to $202 billion in net sales with operating income of $22.5 to $26.5 billion suggests the AI monetization curve is real. Next report lands October 29, 2026. Risk: Q2 cash capex hit $53.1 billion, driving trailing free cash flow negative and forcing new debt issuance to fund the AWS buildout.
Alphabet (GOOGL): The Cheapest Hyperscaler With the Fastest Cloud
Alphabet (NASDAQ:GOOGL) trades at $346.36, up 10.8% year to date and a striking 71.99% over the last year. Yet the P/E is only 15, the lowest of the three by a wide margin. That valuation gap is the setup.
Q2 FY2026 revenue reached $119.80 billion, up 24.23%, with Google Cloud revenue of $24.77 billion growing 82%. Operating margin expanded to 34%. On the AI adoption front, CEO Sundar Pichai noted “nearly 90% of the Fortune 100 using” Gemini Enterprise, while the Gemini App reached 950 million monthly active users.
Sentiment supports the setup. Alphabet’s composite sentiment score sits at 62.34, bullish with medium confidence, and the 30-day change is +5.62 points. Reddit’s r/wallstreetbets flipped bullish again this week at a sentiment score of 65.
Bull case: Fastest-growing hyperscaler at the lowest multiple, plus 12 straight quarters of double-digit revenue growth. Risk: Q2 free cash flow turned negative $5.86 billion as capex more than doubled year over year, and the company suspended its buyback program in Q2. Leadership turnover at DeepMind briefly weighed on the stock in early August.
What to watch next: Azure’s constant-currency guide of ~45% for Q1 FY27, AWS’s October 29 report, and whether Google Cloud can hold 80%+ growth into Q3. If the backlogs keep converting, the AI capex thesis holds. If not, the free cash flow squeeze becomes the story.
