Amazon Soars 13% on AWS's 37% Growth While Apple Sinks 7%: Earnings Week Wrap
July 31 results: Amazon beat with $200.6B revenue and AWS's fastest growth since 2021 (+37%); Apple beat on every metric yet fell 7% on memory-shortage guidance. The 'AI receipts' rule now governs Big Tech.
Bottom line: on July 31, Amazon surged 13% as AWS grew 37% — its fastest since 2021 — while Apple beat on revenue, profit, and iPhone sales yet sank 7%. What sank Apple wasn’t results but guidance: memory shortages capped next-quarter growth at 9-11% against 12% expectations. Big Tech’s earnings week thus closed under the same rule as the Microsoft-Meta split a day earlier: only companies showing AI receipts get rewarded.
What did Amazon prove?
- Revenue $200.61B (vs $196.47B expected), EPS $1.97
- AWS +37% to $30.5B — fastest growth in five years, 36.7% operating margin
- Stock +13%; JPMorgan lifted its target to $365
The “AWS is slowing” narrative is dead. After Azure’s +43%, AWS’s +37% is the second proof in one week that cloud is where AI investment actually converts to revenue.
The detail worth flagging: Amazon raised 2026 capex to $220B, citing rising memory costs. The AI bottleneck is shifting from GPUs to memory — we break down the memory crunch separately.
Why did Apple fall despite beating everything?
Every headline number beat, but next-quarter guidance came in at 9-11% growth on “supply constraints” — and those constraints are memory. AI datacenters are absorbing supply, squeezing both availability and cost of chips for devices. Tim Cook’s final earnings call as CEO added symbolic weight to the 7% drop.
The week’s Big Tech scorecard
| Company | Headline | Stock |
|---|---|---|
| Microsoft | Azure +43%, 30M paid Copilot seats | +10% |
| Amazon | AWS +37% (5-year high) | +13% |
| Meta | Expenses +55% → net income -14% | -10% |
| Apple | Memory-driven guidance cut | -7% |
Alphabet, Amazon, and Microsoft added roughly $1.5 trillion in combined market value in a single week. The market is no longer buying “AI” as a theme — it’s picking individual winners with receipts, the endgame of the demand-verification phase that began with the Nvidia-OpenAI circular-financing debate.
FAQ
Q. Apple beat estimates — why did the stock fall 7%? Markets price the next quarter, not the last one. Memory shortages pushed guidance to 9-11% growth versus 12% expected, and that gap outweighed the beat.
Q. Why does AWS growing 37% matter so much? It’s the fastest since 2021 and the second proof in a week (after Azure’s 43%) that AI spending converts into cloud revenue — the core bull argument in the AI-capex sustainability debate.
Q. One-line takeaway from earnings week? AI receipts, not AI budgets, move stocks now: MS and Amazon showed them (+10%, +13%); Meta and Apple couldn’t (-10%, -7%).
