Andy Jassy has moved the goalposts. The Amazon chief executive told analysts last week that Amazon Web Services could eventually surpass $1 trillion in annual revenue, up from a prior forecast of merely hundreds of billions. The division just posted $169 billion in annual recurring revenue and grew 37 percent year over year last quarter, its fastest pace since 2021. No company in history has recorded a trillion dollars of revenue in a single calendar year; Jassy is betting a single division can be the first.

The math behind the trillion

The projection rests on a straight-line assumption: if AWS compounds at 20 percent annually, its ARR reaches the trillion-dollar mark around early 2036, roughly a decade out. That rate is not a promise, it is a scenario. The 37 percent print last quarter was inflated by a surge of AI-related spend, much of it from start-ups such as Anthropic, which has signaled tens of billions in future cloud commitments. Whether that demand sustains, reverts to the pre-AI trend, or accelerates further is the variable the model cannot resolve.

Margins and the capex bill

The profit picture is where the structure gets interesting. AWS carried a trailing-twelve-month operating margin of 37 percent last quarter, a figure built on years of sunk infrastructure investment. Amazon has guided for as much as $220 billion of capital expenditure this year, the bulk of it earmarked for data-center expansion. Applying the current margin to a trillion dollars of revenue implies $300 billion to $400 billion of operating earnings from the cloud unit alone. For context, Amazon’s entire consolidated operating profit over the past twelve months was $98 billion.

What the retail side adds

The retail business is not a rounding error. North American e-commerce generated $450 billion in revenue over the same twelve-month period and is on track to hit a trillion dollars of revenue before AWS does, albeit at materially lower margins. Advertising, a high-margin layer sitting on top of the retail platform, adds further earnings density. Combined, the three engines could produce consolidated earnings in the $400 billion range by the middle of the next decade, according to the bull case.

The valuation gap

At a $2.8 trillion market capitalization, the stock trades at roughly seven times that hypothetical $400 billion earnings figure. A conventional 20-times multiple on those earnings would imply an $8 trillion valuation, a threefold return over ten years. That arithmetic only works if the growth, margin, and multiple assumptions all hold simultaneously. The market is currently pricing something well short of that outcome.
