Amazon Wouldn’t Be Doing What It’s Doing if AI Capex Was Going to Fail
Andy Jassy just committed roughly $200 billion in capital expenditures for 2026, and the logic behind that number reveals something most investors are missing about where AWS demand is actually coming from.
I keep hitting the buy button on Amazon (NASDAQ:AMZN | AMZN Price Prediction) because Amazon would not be unleashing the AI capex it is unleashing if there was a reasonable chance it was going to fail. That is the whole thesis in one sentence. When a management team with a two-decade record of long-duration bets tells shareholders it plans to spend about $200 billion in capital expenditures across 2026, that reflects a company reading its own order book and building against it.
What the Order Book Actually Says
The order book is the part I cannot ignore. AWS backlog sat at $496 billion, growing triple digits year over year, on a segment already running at a $169 billion annualized revenue run rate. Andy Jassy told investors the lion’s share of AWS capacity planned for 2027 is largely reserved, with “quite a bit of capacity” already reserved for 2028. Customers are pre-committing years of demand. Amazon is pouring concrete against contracts.
The economics of that concrete are what convince me to keep adding. Jassy walked through it plainly: data centers have 30-plus year useful lives, servers break even in a little less than three years and then run for at least five to six years, with most AI capacity contracted for at least five-year terms. That is a compounding annuity dressed up as a capex line.
Numbers That Earned My Conviction
Q2 FY2026 gave me three receipts. AWS grew 37% year over year, the fastest AWS growth in 18 quarters, at a 39.4% operating margin. Operating income across the company rose 43% year over year to $27.46 billion. And the AI and custom chip businesses each cleared a run rate of more than $25 billion, both growing at triple-digit rates. Trainium2 is fully subscribed, and Anthropic committed up to 5 GW while OpenAI committed about 2 GW starting 2027. Balance sheet strength backs the build: debt/equity of 0.37, net debt/EBITDA of 0.45, interest coverage of 35.17.
Why AMZN Instead of the Other Two Hyperscalers
The reader reaches for Microsoft (NASDAQ:MSFT) or Alphabet (NASDAQ:GOOGL). I own the cloud franchise with the fastest listed acceleration and a P/E of 35 attached to a business Jassy believes could be a trillion-dollar annual revenue business for us in time. Amazon also owns something the other two do not: a vertically integrated chip stack where Graviton is used by 98% of Amazon’s top 1,000 EC2 customers and management is actively exploring selling Trainium chips separately from AWS cloud services. That is optionality I am not paying for.
Risk I Refuse to Wave Away
Free cash flow already turned negative at -$7.6 billion TTM, with Q2 capex of $54.21 billion, up 68.4% YoY. If demand cracks, that spend becomes a stranded asset problem. I sit with that risk because the contracted backlog, five-year customer terms, and 30-year data-center life all say the demand is already booked. Jassy’s own words: “We’re enthusiastic about the ROIC equation, even with heavy CapEx the next few years.”
Why the Buy Button Stays Active
Jassy says 85% of global IT spend is still on-premises and that equation flips over the next 10 to 20 years. My retirement horizon is exactly that long, and I plan to own the company pouring the foundation while everyone else argues about the paint.
