Amazon's trailing revenue has passed Walmart's in our stored series: $775.7B versus $735.8B, a $39.9B gap. The milestone needs two caveats: Amazon includes AWS, and the companies' fiscal windows are near-contemporaneous rather than identical.
The crossover is real in our stored trailing-twelve-month series. Amazon has $775.7 billion of revenue through 2026 Q2, growing 15.8%, while Walmart has $735.8 billion through its fiscal 2027 Q2, growing 6.2%. Amazon is ahead by $39.9 billion, or 5.4%, and the growth rates differ by 9.6 percentage points. If those rates simply continued for another year—not a forecast, just arithmetic—the gap would widen to roughly $117 billion. That makes the milestone less interesting as a single crossing than as the possible start of a sustained divergence.
The comparison needs two important qualifications. Amazon and Walmart do not have the same business mix. Amazon's total includes AWS, currently running at about $169 billion annualised, growing 37%, and earning a 39.4% operating margin. Walmart has no equivalent. Strip AWS out and Amazon's retail-related revenue remains below Walmart's, so the headline is true for the consolidated companies but misleading if read as a pure retail comparison. The fiscal windows are also near-contemporaneous rather than identical because Walmart's fiscal calendar is shifted.
The useful conclusion is therefore narrower than the viral chart. Walmart was 68 times Amazon's size twenty-five years ago and now trails it on consolidated revenue, but much of the final step came from Amazon building a high-margin cloud business alongside retail. The next question is not merely how quickly the top-line gap widens. It is whether retail-only Amazon ever passes Walmart, and how much cash each company converts from a dollar of revenue. Revenue marks the historical crossover; mix, margins and cash generation explain what it actually means.
· Morgan Stanley call via PolymarketMoney · positive
Morgan Stanley's path to $1T of annual AWS revenue requires 19.5–24.9% growth for eight to ten years—slower than today's 37%. The harder assumption is absolute scale: at today's margin, AWS alone would generate about $394B of operating income.
Morgan Stanley's reported long-range case has AWS reaching $1 trillion of annual revenue in eight to ten years. Reposts often present that as a spectacular growth claim, but the required rate is less dramatic than the headline. AWS is currently running at about $169 billion a year after a $42.2 billion quarter, up 37%. Moving from $169 billion to $1 trillion requires roughly 24.9% annual growth over eight years or 19.5% over ten. Both paths assume substantial deceleration from today's rate.
The difficult part is the denominator. One trillion dollars of AWS revenue would be 1.29 times the current revenue of all Amazon, including every retail operation, subscription, advertisement and cloud service. If AWS somehow retained its current 39.4% operating margin at that scale, it would produce about $394 billion of operating income. That is roughly 3.6 times Amazon's current annualised operating income. The margin calculation is an illustration, not Morgan Stanley guidance, and a 2034 figure should not be mistaken for a like-for-like comparison with a 2026 company. Still, it shows that the call is fundamentally a statement about how large the global cloud market can become.
There is also a concentration question. Amazon's latest quarter included $53.4 billion of non-operating pre-tax other income, primarily tied to its Anthropic stake, while AI companies are important customers and partners in the cloud buildout. A decade-long AWS path is partly a bet that AI demand expands without economics collapsing at the model layer. The clean way to evaluate the $1 trillion claim is therefore not to ask whether AWS can compound—it already is—but whether the addressable market, capital requirements and customer economics can support a cloud business larger than all of Amazon today.
