Amazon’s Enterprise ‘Hotel California’ Lock In Is Excellent for Investors

I have spent another quarter studying Amazon (NASDAQ:AMZN | AMZN Price Prediction) and its cloud business. Every quarter I look for a reason the thesis breaks. Every quarter, Amazon Web Services gives me another reason it holds.
AWS Lock-In Keeps Enterprises Checking In for Decades
My whole thesis comes down to what I call the Hotel California effect. Once an enterprise migrates its core data architecture, petabytes of proprietary corporate data, and machine-learning pipelines into AWS, switching costs are practically prohibitive. Those customers stay for decades. On the Q3 call, Andy Jassy described the cycle: customers “prefer their production inference to be near the rest of their data and apps,” and those AI workloads then pull in more core compute, storage, and networking. Every new AI project makes it harder for a customer to leave.
Three Receipts I Cannot Ignore
First, growth keeps speeding up even at this size. AWS revenue reached $45.98 billion in Q3, up 39%. That was its fastest growth in nearly five years, and the business now runs at $184 billion a year. Management projects growth above 40% both in 2027 and in 2028. AWS backlog stands at $578 billion.
Second, the lock-in shows up in the numbers. Fortune 500 spending on Bedrock rose ~7x, and Bedrock token volume rose ~17x. AgentCore customers deployed 2x more agents in Q3 than the prior three quarters combined. Agents built into a company’s workflows rarely get moved somewhere else.
Third, the profits are real. AWS operating income rose to $17.77B vs $11.43B a year earlier. Amazon’s 13.9% operating margin was its highest ever. The company’s debt-to-equity sits at 0.37, with interest coverage of 35.17.
Why My Money Skips Microsoft and Alphabet
An excellent cloud powers Microsoft (NASDAQ:MSFT), and Azure grew 48%. Still, Azure revenue of $33.165 billion trails AWS. Microsoft’s Devices and Consumer segment also contracted 3%, and Windows OEM and Devices fell 22%. I want my cloud exposure combined with ads and subscriptions that are still growing, and Amazon’s advertising and subscription revenue each grew 11%.
Shares of Alphabet (NASDAQ:GOOGL) trade at about 13x earnings, compared with 38x for Amazon. I still pass. Equity-securities changes distort Alphabet’s reported earnings: a $99.0 billion gain in Q2, then an $8.7 billion loss in Q3. To help fund its expansion, it also sold 12 million Class A and 24 million Class C shares through a share sale. I want my ownership stake to stay whole.
Where This Position Can Hurt Me
The capex bill is enormous. Amazon expects to spend about $220B on capital projects in 2026. Q3 capex alone reached $77.26B, and free cash outflow over the past 12 months hit $42.4B. Long-term debt rose to $119.1B from $65.6B by the Q1 report. With a free cash flow yield of just 0.26%, the stock has little buffer if AI demand cools.
That expansion has to be powered, cooled, and networked by somebody, and the suppliers behind it are a quieter way to play the same trend (we featured seven of them here: 7 Stocks Powering the AI Boom (That Aren’t Chipmakers)).
The thesis holds up because the spending follows customer commitments. Jassy says AWS has “very good visibility into 2027 and 2028 and some of 2029” on large capacity reservations. Operating cash flow also rose 19.41% to $42.42B in Q3.
A Runway Measured in Decades
About 85% of global IT spending still sits on premises, and Jassy frames the move to the cloud as a 10- to 20-year cycle. Over the past 10 years, the shares have returned 633.06%, and I build my retirement portfolio around compounders that can last for decades. Enterprises keep checking into AWS and almost never check out, so I keep checking in as a shareholder.
