Amazon's AWS and AI-Driven Growth: The Uncoiling Spring of Long-Term Investor Returns

In the ever-evolving landscape of technology and finance, the concept of the "coiled spring" business model-where years of strategic investment compress energy into a single, explosive release-has found a striking modern exemplar in Amazon's AWS division. UBS's Q3 2025 analysis underscores how Amazon's relentless focus on cloud infrastructure and artificial intelligence is transforming AWS into a force that not only accelerates its own growth but also reshapes investor expectations for the long term.

The Accelerating Engine of AWS

Amazon Web Services (AWS) has long been the backbone of the company's profitability, but Q3 2025 marked a pivotal inflection point. According to , , a figure that reflects not just increased demand for cloud services but also the compounding returns from Amazon's strategic bets in AI. This acceleration is not merely a function of market share expansion; it is a direct result of AWS's ability to integrate cutting-edge AI capabilities into its infrastructure, creating a flywheel effect that amplifies both operational efficiency and customer value.

Consider the case of , which recently trained its Claude AI model on AWS's Trainium2 chips. This partnership exemplifies how AWS is becoming a critical enabler of next-generation AI development, positioning itself as both a platform and a collaborator in the AI revolution. Meanwhile, AWS's access to NVIDIA's Grace Blackwell chips-a move highlighted by UBS-further cements its role as a leader in high-performance computing, a sector poised for exponential growth as AI workloads intensify.

The Coiled Spring in Action

The "coiled spring" analogy, as applied to AWS, captures the interplay between years of underinvestment in public relations and the current explosion of profitability. For much of its history, Amazon prioritized AWS's technical excellence over short-term financial metrics, allowing the division to build a near-monopolistic edge in cloud computing. , and its AI-driven services are generating returns that UBS describes as "springing forward."

This dynamic is further amplified by macroeconomic trends. While UBS notes that macroeconomic uncertainties and currency fluctuations pose risks to its own operations, the same factors are driving enterprises to adopt cloud and AI solutions to mitigate volatility. AWS's scalability and AI tools are thus becoming indispensable for businesses seeking agility-a demand that UBS anticipates will sustain AWS's growth trajectory well into 2026.

Strategic Synergies and Investor Implications

For investors, the implications of AWS's coiled-spring model are profound. , as The Globe and Mail report notes. Amazon's approach mirrors this philosophy: by reinvesting profits into AI R&D and infrastructure, AWS is creating a self-reinforcing cycle of innovation and demand.

Moreover, AWS's partnerships with like Anthropic and NVIDIA illustrate the importance of ecosystem building. These collaborations not only diversify AWS's revenue streams but also lock in long-term customer loyalty, as enterprises become dependent on AWS's AI-optimized infrastructure. For investors, this represents a durable competitive advantage-a "moat" that is increasingly difficult for rivals like Microsoft's Azure or Google Cloud to replicate.

Conclusion: The Long Game

As UBS's Q3 analysis makes clear, the coiled spring is no longer compressed-it is uncoiling. Amazon's AWS division stands at the intersection of cloud computing and AI, leveraging decades of investment to deliver returns that are both immediate and enduring. For long-term investors, the lesson is clear: the companies that master the integration of infrastructure and innovation will define the next era of growth. AWS, with its accelerating momentum and strategic foresight, is not just a beneficiary of this trend-it is its architect.
