Revenue comes from retail, profit comes from AWS and ads
This is the single most useful thing to understand about Amazon. The online store, the marketplace for third-party sellers and the logistics network generate the large majority of revenue, but retail runs on thin margins because shipping, warehouses and staff are expensive. Amazon Web Services — renting servers, storage, databases and AI capacity — and the advertising business that sells placements inside Amazon's own store carry far higher margins and produce most of the operating profit. So a quarter can look mediocre on sales and excellent on profit, or the reverse, depending on which engine did the work.
Why AWS is the number the market reads first
AWS is the largest public cloud provider, and its growth rate is treated as a barometer for corporate technology spending and, increasingly, AI demand. When businesses commit to multi-year cloud contracts, future revenue becomes visible; when they cut or delay, growth slows before anything else does. AWS margin matters just as much as growth, because building AI data centres is expensive and pushes depreciation costs up before the revenue arrives.
The advertising business nobody notices
Amazon has quietly become one of the largest advertising businesses in the world. When you search for a product on Amazon, sellers pay to appear at the top. That is advertising sold against purchase intent — a shopper on Amazon is much closer to buying than someone scrolling a social feed, which is why the inventory is valuable. For investors this line matters because it is high margin and grows with the marketplace, adding profit without adding warehouses.
What moves AMZN stock
First, the AWS growth rate and cloud margin. Second, consumer spending and retail margins — Amazon is a direct read on the health of the household. Third, advertising revenue growth. Fourth, capital spending: data centres, delivery capacity and robotics consume cash now, and the market's patience with that varies with sentiment. Fifth, macro conditions, because a business valued on future cash flows re-prices when interest rates and bond yields move.
Amazon versus Microsoft, Alphabet and Walmart
In cloud, Amazon competes with Microsoft's Azure and Alphabet's Google Cloud; AWS is the largest, so it defends share rather than chasing it. In advertising it competes with Alphabet and Meta, but with better purchase-intent data. In retail its closest comparison is Walmart, which has been building its own marketplace and advertising business. Amazon is unusual because a downturn in consumer spending and a freeze in corporate IT budgets both show up in the same set of results.
The risks a beginner should understand
Retail margins are thin, so wage inflation, fuel costs and weak consumer demand hit profit quickly. AWS growth can slow when companies optimise their cloud bills. Capital spending is enormous and payback is uncertain. Regulators in the US and EU are examining marketplace practices and the treatment of third-party sellers. And AMZN has historically been a volatile large-cap, with sizeable drawdowns even in good business years.
What YourBet is watching next
The AWS growth rate and whether AI workloads lift it, AWS operating margin as new data centres come online, North American and international retail margins, advertising growth, total capital spending, and any regulatory decisions on marketplace rules. Those six lines explain most of what the share price does over a year.
