Amazon (NASDAQ: AMZN | AMZN Price Prediction) and Microsoft (NASDAQ: MSFT) each posted blowout quarters and jumped on the results. Both hyperscalers leaned hard on AI infrastructure, yet the shape of each beat differs. Amazon delivered its fastest AWS growth in 18 quarters. Microsoft crossed Azure’s first $100 billion year and 30 million Copilot seats. The reactions rhymed, but the businesses underneath diverge sharply.
AWS Reaccelerates While Azure Keeps Scaling
Amazon reported EPS of $5.75 against a $1.8227 estimate on revenue of $200.61 billion, up 19.62% YoY. AWS grew 37% to $42.23 billion at a 39.4% operating margin. Andy Jassy told investors, “AWS is booming, growing 36.7% year-over-year in Q2, our fastest growth in 18 quarters, and our AI and Chips businesses each eclipsed run rates of more than $25 billion.” Advertising climbed 26% to $19.81 billion, and Prime shipped 40% more items same-day or overnight.
Microsoft posted EPS of $4.74 on revenue of $90.01 billion, up 17.75% YoY. Intelligent Cloud jumped 32% to $39.31 billion, Azure grew 43%, and commercial RPO reached $678 billion, up 84%. Satya Nadella framed it as “advancing the frontier on the cost-to-outcome curve.” More Personal Computing slipped 4%, a reminder that Windows and Xbox no longer drive the narrative.
Full Stack vs. Enterprise Focus
Amazon is building a full stack: Trainium and Graviton silicon, Bedrock foundation models, Zoox robotaxis approved by NHTSA, roughly 400 Amazon Leo satellites, and Amazon Now delivery across 250-plus cities. Microsoft narrowed focus to Azure, Copilot, GitHub, and Dynamics, backed by a reworked OpenAI pact that commits $250 billion of Azure services and extends IP rights through 2032.
| Lens | Amazon | Microsoft |
| Core Bet | Own silicon, retail, and logistics | Enterprise cloud plus OpenAI |
| Cloud Growth | AWS +37% | Azure +43% |
| Key Vulnerability | Thin retail margins, tariff exposure | GPU depreciation, partner profit share |
The Next Test Is Capex Discipline
Both are spending like utilities. Amazon burned $54.21 billion of capex in one quarter, up 68.44%, and TTM free cash flow flipped to negative $7.6 billion. Microsoft ran full-year capex to $115.95 billion, up 109.63% in Q4, and quarterly free cash flow fell 23.19% to $19.64 billion. Prediction markets lean bullish, with a 60.71 composite sentiment score on AMZN and 64.09 on MSFT. Watch whether AWS holds near a 39% margin and whether Azure’s GPU depreciation cycle starts to bite.
Why I Lean Amazon After This Quarter
Amazon reads better here. Operating income jumped 43.24% YoY even as capex surged, and the AI and custom chips businesses are already each past a $25 billion run rate. AMZN’s trailing P/E of about 22 looks reasonable next to its reaccelerating cloud engine. Microsoft owns the enterprise stack, but heavier merchant GPU depreciation and OpenAI profit-sharing now press against its 46.8% operating margin. For steadier compounding and a 0.77% dividend, Microsoft screens as the more defensive profile. Coming out of this quarter, Amazon shows the stronger operational setup.
