Amazon's Next Chapter: A Look Back at 2025 and What Investors Should Expect in 2026

Amazon enters 2026 in a stronger, more diversified position as AWS regained momentum in 2025 with mid-to-high-teens revenue growth driven by enterprise AI workloads, custom Trainium/Inferentia silicon and Bedrock, while advertising became the fastest-growing segment with annualized revenue topping $60 billion aided by Prime Video’s ad tier, Fire TV integration and DSP expansion beyond Amazon properties. Retail growth moderated—North America e‑commerce rose 11% in Q3 2025 and international 14%—but remains strategically important; capex jumped to $92 billion in the first nine months of 2025 from $55 billion a year earlier, creating near-term margin pressure while 2026 will be a test of whether higher AWS utilization and ad-led expansion translate into improved operating leverage and materially stronger profitability.

Analysis

AWS reasserted itself as Amazon's primary profit engine in 2025, with cloud revenue growing in the mid-to-high teens driven by enterprise AI workloads and Amazon's custom silicon (Trainium, Inferentia) alongside Bedrock making generative-AI deployment easier; this emphasis on backend AI increased customer stickiness and expanded long-term addressable market. Advertising became the company's fastest-growing segment, with annualized ad revenue exceeding $60 billion aided by Prime Video's ad-supported tier, Fire TV integration, high-conversion sponsored products, and DSP expansion beyond Amazon to partners including Netflix and Roku, positioning ads as a meaningful and higher-margin earnings driver. Retail slowed but remained strategically essential: North American e-commerce rose 11% in Q3 2025 and international sales rose 14% year-over-year, while the business continues to supply first-party data for AWS and advertising; however, capital expenditures surged to $92 billion in the first nine months of 2025 from $55 billion a year earlier, creating near-term margin pressure. 2026 is a transition year to watch — if AWS utilization ramps and ad monetization scales, Amazon could convert heavy capex into improved operating leverage, but timing of that payoff is uncertain and will determine near-term profitability dynamics.

Key Decisions for Investors

• Monitor AWS AI workload mix, utilization metrics, and any guidance on margin improvement before increasing exposure to AMZN
• Track advertising revenue trends, DSP expansion off-Amazon and CTV monetization as leading indicators of margin expansion
• Treat retail as a strategic growth-supporting asset but focus on signs of margin improvement from automation and AI rather than topline growth alone
• Avoid assuming immediate profitability gains from 2025 capex — consider staging new purchases or using hedges until 2026 demonstrates improved operating leverage
