Amazon Q4 2025 Earnings Summary: AWS Re-Accelerates on AI Demand as Amazon Leans Into a Massive 2026 Investment Cycle
AWS Re-Accelerates as Amazon Doubles Down on AI, Cloud, and Scale
Amazon closed Q4 2025 with a strong quarter powered by accelerating growth in its highest-margin engines — AWS and Advertising — while retail execution remained steady with record delivery speeds and continued gains in Everyday Essentials and grocery. Revenue came in at $213.4 billion (+12% y/y ex-FX), modestly ahead of expectations, and operating income was ~$25.0 billion, also slightly ahead of consensus despite $2.4 billion of special charges tied to tax/legal settlements, severance, and asset impairments.
The big narrative shift came from management’s tone on 2026: Amazon expects to invest ~$200 billion in capex, largely in AWS, to meet what it described as “very high demand” for both core cloud migration and AI workloads. That spending is raising questions about near-term margins and ROIC timing, but management emphasized a familiar AWS playbook: build capacity, monetize quickly, and compound returns over time.
Key Financial Highlights
Revenue: $213.4B (vs. ~$211.4B consensus)
Operating Income: $25.0B (vs. ~$24.8B consensus)
Operating Margin: 11.7% (in-line; up y/y)
Trailing 12M Free Cash Flow: $11.2B
Paid Units Growth: +12% y/y (highest quarterly growth of 2025)
Capex: $39.5B (above expectations)
FY26 Capex Outlook: ~$200B (predominantly AWS)
AWS: Growth Re-Accelerates to 24% as AI Stack Scales
AWS was the headline winner. Revenue reached $35.6B, and growth accelerated to 24% y/y — the fastest in 13 quarters — as customers leaned into both traditional cloud migrations and rapidly expanding AI demand. AWS operating income was $12.5B, beating expectations.
Management underscored a few key drivers:
Core cloud migration is re-accelerating as enterprises resume moving infrastructure from on-prem to cloud.
Customers want AI where their data already lives, reinforcing AWS’s advantage in “AI next to data + apps.”
AWS’s “top-to-bottom” AI stack is gaining momentum — not just chips, but tools to build and deploy AI in production.
Two metrics stood out:
AWS annualized run-rate: $142B
Bedrock: now a multi-billion dollar run-rate product, with customer spend up 60% q/q.
AI Chips: Trainium + Graviton Become a Real Business (Not a Side Project)
Amazon’s custom silicon push is moving from strategy to scale:
The chips business (including Graviton + Trainium) is now >$10B annual run-rate, growing triple digits y/y.
Graviton is used by 90%+ of AWS’s top 1,000 customers and is growing 50%+ y/y, with up to 40% better price-performance than leading x86.
Trainium2 ramped quickly (1.4M chips landed), and management says Trainium3 demand is strong with supply expected to be nearly fully committed by mid-2026.
The strategic message: Amazon wants to be the low-cost infrastructure provider for AI — and it’s investing accordingly.
Agents: Amazon Positions AWS as the “Production Layer” for Enterprise AI
Management repeatedly emphasized that agents are the next major phase of AI value creation and highlighted new AWS offerings aimed at making agents easier to build and safer to deploy:
Strands (agent creation from any model)
Bedrock AgentCore (secure deployment + governance + monitoring “production plumbing”)
First-party agents like Kiro (coding), AWS Transform (migration), Amazon Q (enterprise knowledge work), and Amazon Connect (contact centers)
Early traction: Kiro developer usage up 150% q/q
Amazon is effectively pitching AWS not just as compute, but as the operating layer where enterprise AI becomes real workflows.
Stores: Delivery Speed, Everyday Essentials, and Quick Commerce Keep Compounding
Retail was steady-to-strong:
North America revenue: $127.1B (+10% y/y)
International revenue: $50.7B (+11% y/y ex-FX)
Third-party seller mix: 61% of units (still a major selection + margin driver)
Key themes:
Everyday Essentials grew nearly 2x the rate of other categories and now represents ~1 in 3 units sold in the U.S.
Amazon is now a major grocer with >$150B in gross sales, and management plans 100+ new Whole Foods over the next few years.
Same-day delivery continues to scale (nearly 70% more same-day items delivered in the U.S. vs. prior year).
Amazon is also testing ultra-fast delivery (Amazon Now, ~30 minutes) and expanding features like Add to Delivery, which already represents ~10% of Prime volume fulfilled through Amazon’s network each week.
Advertising: Another Strong Quarter at +22%
Amazon Ads revenue was $21.3B (+22% y/y), with management highlighting:
Continued strength in Sponsored Products
Expansion and monetization of Prime Video ads (now in 16 countries; ~315M global ad-supported audience)
New AI tools like Ads Agent and Creative Agent to automate campaign creation and optimization
Ads is increasingly a structural profit engine that helps fund aggressive investment elsewhere.
Guidance and Outlook: Q1 In-Line, Investment Cycle Front and Center
Q1 Guidance
Revenue: $173.5B–$178.5B (roughly in-line at midpoint)
Operating income: $16.5B–$21.5B (midpoint roughly flat y/y)
Management flagged two near-term cost headwinds:
~$1B of incremental y/y costs tied to Amazon Leo (satellite launches and scaling)
Higher investment in quick commerce and sharper pricing internationally
Here’s Our Take
Amazon’s Q4 print reinforced the core bull case: AWS is re-accelerating, and the company is building a full-stack AI platform that spans chips → models/tools → agents → production deployment. Add Advertising at +22% and a retail engine that continues to win on convenience and delivery speed, and the business looks well-positioned going into 2026.
The debate now shifts to one question: does the ~$200B capex cycle earn outsized returns? Management is essentially saying this is a once-in-a-generation infrastructure buildout driven by AI demand — and that AWS has a strong track record of translating capacity into high ROIC over time. Bears will argue that the spending signals intensifying competition and could pressure margins if demand or pricing doesn’t hold.
Net: this quarter looked solid operationally, but the stock narrative will be shaped less by Q4 results and more by how quickly Amazon can monetize the AI buildout — and how convincingly it can prove that this capex wave is an investment opportunity, not an arms race.
