Walmart (WMT +1.15%) has spent the past several years building digital scale. E-commerce continues to grow at a healthy pace, its online marketplace where others sell things is growing, and same-day pickup and delivery fueled by online ordering now reach a large portion of U.S. households.
On the surface, the digital strategy looks successful. But scale alone is not the real test of success.
In 2026, the more important question is whether Walmart's digital expansion translates into higher returns on capital -- or merely preserves competitiveness in a tougher retail environment.

Closing the gap is not the same as gaining an edge
Walmart has significantly narrowed the digital gap with Amazon. Its store network now functions as a fulfillment engine, enabling faster pickup and delivery without building an entirely new logistics footprint. That infrastructure advantage is real.
However, digital growth in retail can be economically complex. E-commerce often carries lower margins due to fulfillment costs, returned items, and promotional (sales) intensity. Growth without operating leverage can dilute profitability rather than enhance it.
In other words, the issue in 2026 is whether Walmart's omnichannel model produces superior economics. If digital growth improves asset utilization and lowers per-unit fulfillment costs, the store base becomes a bigger structural advantage. If it simply offsets competitive pressure, there is no enhancement of scale advantage.

Spending to improve
Maintaining digital competitiveness requires ongoing investment. Walmart continues to allocate money to technology and supply chain enhancements. These investments aim to increase productivity and reduce friction in both physical and online channels.
WMT Capital Expenditures (TTM) data by YCharts
At Walmart's size -- more than $700 billion in annual revenue -- even modest increases in capital expenditures amount to significant dollars. For the current fiscal year, Walmart says it is targeting capital expenditures at roughly 3.5% of sales; 3.5% of $700 billion is $24.5 billion. If return on invested capital remains flat while digital investment grows, shareholders are funding maintenance rather than improvement.
What does success look like?
True digital success should show up in three places:
- Gradual improvement in operating leverage, which looks at how much increases in the top line increase the bottom line.
- Stable or improving return on invested capital despite higher investment.
- Margin resilience even in competitive pricing environments.
If those conditions materialize, Walmart's digital effors become a compounding advantage. Its physical footprint, combined with data and automation, could yield a hybrid model difficult to replicate.
If not, Walmart remains a strong retailer, but one investing heavily simply to hold its position.
For long-term investors, 2026 will help clarify whether Walmart's digital strategy deepens its competitive advantage or merely sustains it.
