The bears had a simple thesis: Big Tech was spending hundreds of billions on artificial intelligence infrastructure, and there was no proof the revenue was actually coming back. This week, that thesis fell apart.
Amazon (AMZN) and Microsoft (MSFT) both reported earnings late in the week of July 28, 2026, and what they showed was not just a beat — it was an acceleration. Cloud computing, the backbone of the AI trade, grew faster than it did the prior quarter for both companies. The market noticed. Amazon shares surged 15.72% on July 31 to $272.53, approaching its 52-week high of $278.56. Microsoft rose 2.46% to $462.18, though it remains well below its 52-week high of $553.72. Both stocks are sending a clear message to investors: the AI buildout is generating real demand.
Amazon: $200 Billion in a Quarter, and AWS Just Got Faster
Amazon crossed a milestone in Q2 2026, reporting net sales of $200.61 billion — the first time in company history it surpassed $200.00 billion in a single quarter. That revenue figure represents 20% growth year over year, Amazon's fastest pace of expansion in four years. Operating income grew 43% to $27.46 billion, pushing the quarterly operating margin to a record 13.7%.
The headline EPS of $5.75 included a $53.40 billion non-operating gain tied primarily to an unrealized valuation increase on Amazon's investment in Anthropic. Strip that out, and the clean operating story is still exceptional: operating profit of $27.46 billion on a 13.7% margin is the best in Amazon's history.
The number that matters most to investors who follow the AI trade is AWS. Amazon Web Services posted revenue of $42.20 billion, up 37% year over year — its fastest growth rate in 18 quarters. AWS operating income climbed to $16.60 billion, with an operating margin of 39.4%, up from roughly 33% a year ago. AWS alone now generates more than 61% of Amazon's total operating profit. The segment is running at a $169.00 billion annualized revenue rate, with a $496.00 billion order backlog giving the business rare long-term visibility.
Advertising was another bright spot, with revenue up 26% to $19.80 billion. For Q3 2026, Amazon guided net sales to a range of $197.00 billion to $202.00 billion, with operating income of $22.50 billion to $26.50 billion. Management raised full-year capital expenditure guidance to $220.00 billion, signaling continued confidence in AI-driven demand through 2027 and beyond.
Of 18 analysts covering AMZN, 94.4% rate it a Buy or Outperform. The average price target is $332.94, with a street-high of $400.00. At $272.53, the stock trades at a P/E of 32.60 on TTM earnings heavily distorted by the Anthropic mark. The 52-week range is $196.00 to $278.56.
Microsoft: Azure Crosses $100 Billion, and the Beat Was Real
Microsoft closed its fiscal year 2026 with a Q4 that cleared every major estimate. Revenue came in at $90.01 billion, up 18% year over year, above the prior guidance range of $86.70 billion to $87.80 billion. Operating income reached $40.60 billion at a 45% operating margin. EPS was $4.81 for the quarter.
The defining moment of the print was Azure. Azure and other cloud services revenue grew 43% in Q4 — above management's own guidance of 39% to 40% and an acceleration from the 40% growth rate in Q3. CEO Satya Nadella disclosed that Azure crossed $100.00 billion in annualized revenue for the first time in history. Total Microsoft Cloud revenue reached $59.30 billion, up 27%.
Unlike Alphabet's Q2 beat — which relied partly on a large investment gain to inflate EPS — Microsoft's beat was clean. Operating income of $40.60 billion carries no investment-gain distortion, and management confirmed the company exceeded expectations across revenue, operating income, and EPS even after stripping out a $3.20 billion Anthropic-related gain. This marks Microsoft's 16th consecutive quarter of beating analyst estimates.
Microsoft spent roughly $88.00 billion on capital expenditures in fiscal year 2026, and Azure's acceleration to 43% growth is the clearest evidence that those dollars are translating into incremental revenue. The company has publicly said AI capacity constraints have eased and GPU utilization has improved — a positive sign for margins going forward.
Of 19 analysts covering MSFT, 94.7% rate it a Buy or Outperform. The average price target is $547.89, with a street-high of $650.00. At $462.18, the stock trades at a P/E of 28.55 and sits more than 16% below its 52-week high of $553.72. The 52-week low is $349.20, and the market cap stands at $3.43 trillion.
The combined takeaway from this earnings week is straightforward: the four hyperscalers — Amazon, Microsoft, Meta, and Alphabet — collectively plan to spend between $720.00 billion and $745.00 billion on capital projects in 2026. AWS growing at 37% and Azure growing at 43% are proof that the demand is real and accelerating. For investors, AMZN and MSFT remain the two clearest ways to own that theme directly.
