Amazon is dominating the financial headlines right now, and sure enough, AWS grew 24% in Q4 and the AI story is real. But here’s what you really should see.
I have seen this movie before. A company announces a jaw-dropping capex plan, the road looks cheery, and retirement accounts quietly absorb risk. Andy Jassy just told the world that Amazon plans to “invest about $200 billion in capital expenditures in Amazon by 2026.” This is not a growth story. This is a condition. And energy prices are variable and nobody’s price is fixed.
WTI crude oil sits at $71.13 per barrel after a 10.3% increase in just the past month. If oil hits $100, it becomes dramatically more expensive to build Amazon’s $200 billion worth of data centers, fulfillment networks, and satellites. Walmart does not. Here’s why.

Amazon added 3.8 gigawatts of power capacity in the past 12 months. Data centers eat electricity. Fulfillment centers operate the fleet. Satellites require launch infrastructure. Its $200 billion capex plan has every dollar of energy invested in it rising as oil prices rise.
The financial signal is already clear. Amazon’s free cash flow fell 65.95% year over year in FY2025 even as operating cash flow grew 20.4%. Increasing capex costs money faster than the business. Add an oil shock on top of that, and the margin cushion gets thinner fast. Amazon has apparently listed energy prices as a risk factor in its future outlook. They know.
Walmart is not under construction. There are shops. A supply chain is established. In-store deliveries now reach 95% of US households within three hours, using prepaid physical locations. It’s a toll bridge that doesn’t need to be rebuilt when energy becomes expensive.
Walmart’s capex discipline tells the whole story: FY26 capital expenditures totaled $26.64 billion, roughly 3.5% of net sales. Amazon plans to spend $200 billion a year. Walmart’s growing energy exposure is manageable. The structure of Amazon.
