AMZN: The $132B Capex Bet That's Working
Key Takeaways
- AMZN trades at $238 with a 33.2x P/E — the lowest multiple in years against 31% net income growth.
- FY2025 capex hit $131.8 billion, crushing FCF to $7.7 billion, but operating cash flow reached $139.5 billion.
- AWS custom Trainium AI chips are fully allocated, and Jassy's shareholder letter boosted analyst confidence in AI monetization.
- Earnings on April 30 will be the next catalyst — watch AWS growth rate and margin to validate the infrastructure bet.
Amazon spent $131.8 billion on capital expenditure in FY2025. That's more than the GDP of most countries, and it's the number that separates Amazon from every other tech company on earth. The market is starting to reward that spending — AMZN trades at $238, up 44% from its 52-week low of $165, with a $2.56 trillion market cap.
The bull case rests on one division: AWS. Andy Jassy's latest shareholder letter sent Jefferies reiterating a Buy with a $300 target, calling out improving visibility on AI growth. AWS generated the majority of Amazon's operating profit while representing roughly a quarter of revenue. The custom Trainium AI chips are sold out. Cloud revenue is accelerating.
At 33x trailing earnings, Amazon isn't cheap — but it hasn't been cheap since 2008. The question is whether the AI infrastructure buildout generates the returns to justify the spend, or whether Amazon is building the world's most expensive stranded asset.
Valuation: Premium Justified by Profit Trajectory
AMZN trades at 33.2x trailing EPS of $7.17. That's the lowest P/E Amazon has traded at since the post-pandemic normalization. Enterprise value of $2.54 trillion against $716.9 billion in trailing twelve-month revenue gives an EV/Sales of roughly 3.5x — reasonable for a company growing revenue 10% annually.
Price-to-book is 6x, and EV/EBITDA is 54x on the most recent quarter's annualized figure. The price-to-operating-cash-flow ratio of 45x looks rich until you realize Amazon plows most of that OCF back into infrastructure.
The earnings trajectory matters more than the current multiple. FY2025 net income was $77.7 billion, up 31% from $59.2 billion in FY2024. Analyst estimates project EPS growing to roughly $5.90 by 2028, implying continued 15-20% annual earnings growth.
Revenue: Four Engines Firing
FY2025 revenue hit $716.9 billion across four quarters: Q1 $155.7B, Q2 $167.7B, Q3 $180.2B, Q4 $213.4B. The Q4 spike reflects holiday retail seasonality, but the underlying trend is 10% year-over-year growth sustained at massive scale.
Gross margins expanded meaningfully — from 50.6% in Q1 to 48.5% in Q4, with the full year averaging around 50%. Operating margins reached 11.7% in Q4, the highest quarterly level in recent history. The margin expansion story is real and driven by AWS leverage, advertising growth, and fulfillment efficiency gains.
The advertising segment deserves specific mention. Amazon's ad business is now a high-margin profit center rivaling YouTube's scale, and it barely existed five years ago. It's the hidden earnings engine that subsidizes retail's thin margins.
The Capex Question
Amazon spent $131.8 billion on capex in FY2025, up 59% from $83 billion in FY2024. Operating cash flow was $139.5 billion, meaning free cash flow collapsed to $7.7 billion — down 77% from $32.9 billion the prior year. On a per-share basis, FCF fell to $1.39.
This is the number bears fixate on, and they have a point. Amazon is spending nearly every dollar it generates building AI data centers, delivery infrastructure, and logistics networks. The capex-to-OCF ratio hit 94.5% — essentially reinvesting everything.
But context matters. Amazon's FY2022 capex cycle produced negative $16.9 billion in FCF. The market punished the stock. Then AWS margins expanded, retail efficiency improved, and FCF recovered to $32.9 billion by FY2024. The current capex surge follows the same playbook: invest aggressively during a technology transition, then harvest margins as the infrastructure starts earning.
The risk is that AI infrastructure has a shorter useful life than traditional cloud compute. If Trainium chips become obsolete in three years instead of five, the depreciation curve steepens and margins compress.
AWS and the AI Monetization Path
AWS remains Amazon's profit engine. While exact segment breakdowns for Q4 2025 aren't fully broken out in the income statement data, operating income of $25 billion for the quarter reflects AWS's dominant contribution.
Jassy's shareholder letter highlighted three AI developments: Trainium custom chips are fully allocated to customers, Bedrock (Amazon's managed AI model service) is gaining enterprise traction, and AWS's AI revenue run rate is accelerating. Jefferies cited these disclosures as evidence that the AI investment is generating visible returns.
Amazon's competitive advantage in AI infrastructure is vertical integration. Unlike customers who buy Nvidia GPUs at market prices, Amazon designs its own Trainium inference chips and Graviton general-purpose processors. This gives AWS structurally lower compute costs — and that margin advantage compounds as AI workloads scale.
The SaaS selloff that crushed ServiceNow and CrowdStrike is actually bullish for Amazon. If AI agents replace enterprise software, those agents run on cloud infrastructure. AWS is the picks-and-shovels play on the AI infrastructure thesis.
Forward Outlook: Earnings April 30
Amazon reports Q1 2026 earnings on April 30. Analyst consensus for FY2028 projects revenue around $298 billion on a quarterly basis (roughly $1.2 trillion annualized) with EPS of approximately $5.89 per quarter. These are forward-looking estimates that assume sustained cloud growth and margin expansion.
The fuel surcharge announced for some customers is a non-event — a rounding error at Amazon's scale, but it signals management's willingness to protect margins during the tariff environment.
The stock sits at $238 against a Jefferies target of $300, implying 26% upside. The 50-day moving average of $213 is now support after the recent rally. The 52-week high of $258.60 is the next resistance level, just 8.6% above current price.
The key metric to watch on April 30 is AWS revenue growth rate and margin. If AWS shows acceleration above 20% growth and operating margins hold above 30%, the stock likely breaks through the $258 high. A deceleration would raise questions about whether the $132 billion capex bet is paying off fast enough.
Conclusion
Amazon at $238 is a bet on AI infrastructure monetization at scale. The 33x trailing P/E is the lowest multiple the stock has traded at in years, and the earnings growth trajectory — 31% net income growth in FY2025 — justifies paying up.
The risk is concentrated in the capex cycle. At $132 billion annually, Amazon needs AWS AI revenue to scale rapidly to avoid an FCF crunch. The playbook has worked before (2022 capex → 2024 FCF recovery), but the magnitude is larger this time. Own it for the AWS AI option value, but size the position for the possibility that the payoff takes longer than the market expects.
