Amazon.com, Inc. (AMZN) | The Buildout — AI Infrastructure
The Verdict
Amazon runs two businesses that matter to the AI buildout. It operates AWS, which rents out compute, storage, database, analytics, and AI services to other companies, and it designs its own chips — Trainium for AI, Graviton for general-purpose computing, and Nitro for networking — that sit inside those data centers. That combination puts Amazon on both sides of the build-out at once: it is one of the largest buyers, spending on land, power, shells, and servers, and through AWS one of the largest sellers of the finished compute. On the model layer, management takes a different position — AWS says customers want choice and it will carry all the leading models, while separately building its own frontier model for cost control.

What We Like
- AWS revenue grew 36.7% y/y to $42.2B in Q2 2026 — the fifth straight quarter of acceleration and the fastest growth in 18 quarters — on a $169B annualized run rate.
- AWS backlog reached $496B, up from $364B in Q1 and growing triple digits y/y, with management saying 2027 capacity is largely reserved and quite a bit of 2028 capacity is already reserved.
- The custom silicon business passed a $25B annualized run rate, growing triple digits y/y, alongside more than $225B of Trainium revenue commitments disclosed in Q1.
- The AI revenue run rate passed $25B annualized in Q2, up from more than $15B in Q1, also growing triple digits y/y.
- AWS operating income was $16.6B at a call-cited ~39% margin, up 650bps y/y or 520bps excluding a derivative gain; management says AI margins are tracking its core cloud business at the same stage of evolution.
What We’re Watching
- FY2026 cash CapEx was raised to ~$220B from ~$200B, attributed to memory costs. Management says Amazon still will not have enough capacity for all 2026 demand and expects the same in 2027.
- About $1.2B of Q2 operating income came from one-offs — roughly $600M of tariff refunds and roughly $600M of an energy-contract derivative gain that management says was not significant in prior quarters.
- TTM free cash flow is -$11.6B as capital spending outruns operating cash flow, against FY2026 cash CapEx guided to approximately $220B.
- Concentration inside the backlog is not disclosed. Two AI labs hold multi-year, multi-gigawatt commitments, and Amazon is also an equity investor in both.
On the evidence in the source, the thesis looks strengthening: AWS growth has accelerated for five straight quarters, the backlog stepped sharply higher, and management says AI margins are tracking its core cloud business rather than diluting it. The offsets are documented just as clearly — capital spending raised on memory costs, negative trailing free cash flow, one-off operating income in Q2, and a backlog whose customer concentration is undisclosed. The open question is whether that backlog proves broad-based or rests largely on two AI labs that Amazon is also financing.
Earnings Beat
Amazon reported Q2 2026 revenue of $200.6B, up 20% y/y ex-FX, with gross margin of 52.3%. Operating income was $27.5B, up 43% y/y, and included about $1.2B of one-off benefits. The standout was AWS: revenue of $42.2B, up 36.7% y/y — a fifth straight quarter of acceleration — and a backlog of $496B growing triple digits y/y.

Revenue growth of 36.7% year-over-year, accelerating for the fifth straight quarter, our fastest growth in 18 quarters…— Andy Jassy, 2026-07-30
Management tone: Across the two calls in the source, management moved from framing AI investment as a once-in-a-lifetime opportunity to describing execution at scale. The Q2 commentary was more confident on demand — 2028 demand described as striking, 2027 capacity largely reserved — and more candid on costs: the CapEx raise was attributed to memory prices, the ~$1.2B of one-off benefits were broken out and separated, and the CFO said AWS margins will fluctuate. Asked about sources of capital for the build-out, management acknowledged debt issuance this year and declined to give detail.
Management Guidance
For Q3 2026, management guided net sales of $197B–$202B and operating income of $22.5B–$26.5B, assuming an unfavorable FX impact of approximately 80bps. Management noted that excluding Prime Day in both 2025 and 2026, Q3 y/y growth would have been nearly 400bps higher. For the full year, FY2026 cash CapEx is guided at approximately $220B, raised from about $200B because of the higher cost of memory.
Trajectory
Revenue is accelerating: Q2 2026 revenue of $200.6B was up 20% y/y ex-FX, after $181.5B in Q1, against a trailing four-quarter growth rate of 15.8%. AWS is where the change is concentrated — growth has gone 24% to 28% to 36.7% y/y across the disclosures in the source. Margins expanded: Q2 gross margin was 52.3% and EBITDA margin 23.7%, versus 51.8% and 23.6% in Q1. The cost side is moving just as quickly — cash CapEx was $43.2B in Q1 and $53.1B in Q2, which is why trailing free cash flow is negative.
The Model
The model projects FY+1 revenue of $833,000M and EBITDA of $187,425M, a 22.5% EBITDA margin. For FY+2 it projects revenue of $970,000M and EBITDA of $237,650M, a 24.5% margin. The near-term anchor in the source is the $496B AWS backlog converting as capacity comes online, with 2027 capacity largely reserved; FY+2 sits further out, where depreciation on a much larger asset base and component costs matter more to the margin line.
| Metric | FY2025 | Next FY (E) | Following FY (E) |
|---|---|---|---|
| Revenue | $716.9B | $833.0B | $970.0B |
| YoY Growth | — | +16.2% | +16.4% |
| EBITDA | $145.7B | $187.4B | $237.7B |
| EBITDA Margin | 20.3% | 22.5% | 24.5% |
Projections are the median of 5 independent model runs. The model’s revenue sits 2.3% above analyst consensus.

What Could Go Right — and Wrong
- The AWS backlog converts as planned: 2027 capacity is largely reserved and some 2028 capacity is already reserved, so revenue follows the build.
- AWS growth extends beyond five consecutive quarters of acceleration — management says demand exceeds capacity in 2026 and likely in 2027.
- AI margins keep tracking the core cloud business, holding the AWS margin near the level cited on the Q2 call rather than diluting it.
- Trainium becomes an externally sold product: management says it is actively in conversations with customers interested in chips separate from the AWS cloud and sees a real chance of doing so.
- The middle of the adoption barbell starts moving — enterprise production workloads adopting inference pervasively — which management calls the largest eventual segment.
- Memory and component inflation keeps raising capital spending; the FY2026 plan already moved from ~$200B to ~$220B, and existing AWS contracts carry fixed prices.
- Capacity, not demand, caps near-term revenue: management says Amazon will not have enough capacity for all 2026 demand, and likely not for 2027 either.
- The backlog proves concentrated in two AI labs that Amazon also invests in and lends to; concentration inside the backlog is not disclosed.
- The AI adoption curve is barbell-shaped: management says the middle — enterprise production workloads — is not yet using inference pervasively and declined to promise the same steep trajectory as the AI-lab ends.
- Free cash flow stays negative longer than expected; TTM FCF is -$11.6B and management gives no date for when revenue growth outpaces incremental capital spending.
Looking Ahead
Over the next twelve months the test is largely mechanical: whether the backlog converts as power and shells come online. Management says AWS power capacity will double by the end of 2027 versus 2025 and that it is on track, with 2027 capacity largely reserved. Amazon Leo is scheduled to begin initial satellite service this year, and selling Trainium outside AWS remains a set of conversations rather than a signed deal.
- Q3 2026Q3 results reported — Tests whether growth holds ex-Prime Day and whether AWS extends.
- 2026Amazon Leo initial service — Initial satellite internet service; the first Leo revenue marker.
- 2027OpenAI Trainium ramp — Roughly 2 GW of committed Trainium capacity begins ramping.
- By end-2027AWS power capacity doubles — Target is double 2025 power capacity; management says on track.

The Company
Amazon reports three segments: North America, International, and Amazon Web Services. The first two carry retail, physical stores, devices, advertising, and the Prime membership program; AWS sells on-demand compute, storage, database, analytics, and artificial intelligence and machine learning services. The 10-K describes the company's stated aim as being Earth's most customer-centric company, serving consumers, sellers, developers, enterprises, content creators, advertisers, and employees. For the AI buildout, AWS is the segment that matters: it was roughly 21% of Q2 2026 revenue, and it is where management says AI demand shows up as disclosed revenue.
Amazon operates its own fulfillment network, data centers, and increasingly its own silicon. The 10-K lists 474,128 and 45,803 of fulfillment, data center, and other space in North America and 185,814 and 20,660 internationally, though the extract does not define the units. It procures power directly: as of March 31, 2026 it held energy contracts for approximately 200 million megawatt-hours with a weighted-average remaining duration of about 15 years, the majority to be delivered beyond the next nine years. Management says Amazon designs its own Trainium, Graviton, and Nitro chips.
Business Segments
Competitive Landscape
The 10-K frames competition broadly. It lists web search engines, comparison shopping websites, social networks, web portals, virtual assistants, and other online and app-based means of discovering, using, or acquiring goods and services, including through artificial intelligence, alongside companies that provide information technology services or products including on-premises or cloud-based infrastructure and AI-related tools. On the AI side, management's stated response is model choice: AWS says it will carry all leading models in Bedrock, expects at least a half dozen comparably good models within a few years, and is separately pursuing its own frontier model mainly for cost control and prioritization.

Supply Chain
Amazon buys GPUs, custom silicon, memory, and power, then sells finished compute through AWS. Its 10-K flags a limited group of suppliers for AI infrastructure semiconductors, including GPUs, and says constraints could hurt its AI work.
