Amazon Web Services is the gravitational center of the Amazon valuation thesis. AWS has been growing at 17% to 20% annually for the past several years. Its operating margins are estimated in the 35% to 40% range, meaning AWS likely contributes $35 to $45 billion or more of the company's $80 billion in total operating income.
Valuing AWS in isolation changes the picture considerably. Cloud infrastructure businesses with 20% growth rates and high margins typically trade at 20x to 30x operating income. At the lower end of that range, AWS operating income of $38 to $42 billion implies a standalone value of $760 billion to $1.26 trillion. That is a wide range, but even the lower bound represents substantial embedded value.
The acceleration of AI workloads on cloud infrastructure is a genuine tailwind for AWS. Enterprise customers building AI applications need compute, storage, and networking at scale. AWS, Azure, and Google Cloud are the three platforms with infrastructure capable of handling that demand. AWS sustained 19% revenue growth through consecutive quarters of 2025, maintaining momentum as AI demand pulled through.
The AI platform race has also deepened the competitive moat. The capital investment required to build credible cloud infrastructure is now so large that no new entrant can realistically challenge the top three. AWS is one of three companies capable of serving the most demanding enterprise AI workloads at scale, and that number is unlikely to grow.
The current capex buildout is directly tied to this dynamic. Amazon is spending $131 billion annually to ensure it does not lose ground in the AI infrastructure competition to Microsoft and Google. Framed that way, the capex looks less like profligacy and more like an unavoidable cost of remaining relevant.
