I keep buying Amazon (NASDAQ:AMZN | AMZN Price Prediction) because the loudest bear case against it, that $200 billion in 2026 capex will torch shareholder returns, was already answered by the company’s own contract book. I have been adding on every wobble because the receipts explain why this spending cycle is closer to a pre-sold order book than a moonshot.
The Backlog Is the Whole Argument
AWS has pre-sold much of this capacity before pouring concrete. On the Q1 call, Andy Jassy said the AWS backlog stood at $364 billion, excluding the recently announced $100 billion+ Anthropic deal. Amazon has disclosed $225 billion in revenue commitments for Trainium alone. When I hear “$200 billion of capex,” I read it against a contracted demand pile that dwarfs it. Jassy said it plainly: “We have high confidence this will be monetized well, as we already have customer commitments for a substantial portion of it.”
Revenue Is Already Moving
The velocity convinces me this is a near-term story. AWS grew 28% year over year in Q1 2026, its fastest pace in 15 quarters, on a $150 billion annualized run rate. The AI slice inside AWS is already at a $15 billion+ run rate, and Bedrock saw 170% growth in customer spend quarter over quarter. Consolidated operating margin hit 13.1%, the highest ever, and full-year 2025 operating cash flow reached $139.5 billion. That is the cash engine funding the buildout.
The Silicon Moat Nobody Prices In
Custom chips crossed a $20 billion annual run rate and grew nearly 40% quarter over quarter. Jassy told analysts Trainium “will save us tens of billions of dollars of CapEx each year and provide several hundred basis points of operating margin advantage” versus buying outside silicon. Trainium2 is largely sold out, Trainium3 is nearly fully subscribed, and Graviton runs inside 98% of the top 1,000 EC2 customers. That is a structural cost advantage over any hyperscaler paying full freight for GPUs.
Why Not Microsoft or Alphabet
The obvious alternatives are Microsoft (NASDAQ:MSFT) and Alphabet (NASDAQ:GOOGL). I own some of both and still keep adding Amazon. Microsoft’s most recent quarterly revenue grew 18.3% year over year, and Alphabet’s grew 21.8%. Amazon’s AWS is growing faster than both at 28%, yet Amazon trades at a trailing P/E of 30, close to Microsoft at 23 and Alphabet at 26, without a proprietary silicon revenue stream on Trainium’s scale. That valuation setup, paired with the fastest cloud growth of the three, keeps my capital flowing to AMZN first.
The Risk I Own With Open Eyes
Free cash flow is the visible bruise. TTM free cash flow fell to $1.2 billion, down 95%, because property and equipment purchases jumped $59.3 billion year over year. Long-term debt climbed to $119.1 billion from $65.6 billion. If AI monetization stalls, the payback window stretches. Jassy addressed this directly: capex funds assets with “many-year useful lives, 30-plus years for data centers, five to six years for chips, servers, and networking gear,” and the free cash flow shows up a couple of years after capacity comes online. I have watched Amazon run this playbook before, and the compounding on the other side is why I stay.
Why the Buy Button Stays Warm
Polymarket traders assign a 93.5% probability to Amazon beating its next quarter, and analyst consensus sits at 62 buy ratings and zero sells. My conviction is simpler. A $364 billion backlog, a $20 billion chip business, and an AI run rate already north of $15 billion tell me the capex was pre-sold, and I intend to keep buying the receipts.
