Walmart's $100 Billion E-commerce Gamble: Can It Dethrone Amazon?

Is Walmart really becoming a serious contender in the e-commerce world, threatening Amazon's long-standing dominance? Let's unpack this.

Walmart's E-commerce Surge: The Hard Data

Walmart’s recent performance offers some eye-catching figures. Its e-commerce sales surpassed $100 billion in the last fiscal year, accounting for 18% of its total revenue. This segment isn't just growing, it's growing fast, 20% in the most recent quarter, marking 11 straight quarters of double-digit growth.

The company’s Walmart+ subscription, priced at $98 annually, is a direct competitor to Amazon Prime, which costs $139. This membership has been key in attracting a wealthier clientele, leading to 75% of the market share gains from households earning over $100,000, as noted in Q3 2025.

Why This Matters: A Shift in Retail Dynamics

Historically, Walmart was seen as the go-to for budget-conscious consumers, offering no-frills, affordable shopping. But the scales are tipping. The shift started around 2022, when inflation prompted higher-income consumers to seek better deals, drawing them to Walmart. The numbers tell the story: Walmart's affluent customer segment grew almost five times faster than its average user base in early 2024.

From a risk perspective, Walmart's physical store network, long considered a liability in e-commerce, is transforming into an asset. Its 4,700 locations can quickly fulfill online orders, giving it a leg up in grocery delivery, something Amazon struggles to match despite its efforts with Whole Foods and Amazon Fresh.

Insider Perspectives: What Experts Are Watching

Neil Saunders from GlobalData Retail explains this trend, saying that middle- and higher-income consumers are realizing they can find their preferred brands, like La Roche-Posay and Rao's, at Walmart but for less. Andrew Lipsman, an independent analyst, highlights that e-commerce naturally draws more affluent customers, suggesting Walmart's investment in digital infrastructure is paying off.

According to Deepak Maini of Walmart+, the program's appeal lies in its hybrid model, allowing both digital and in-store shopping. This versatility is something Amazon can't easily replicate, Maini suggests, despite Amazon's broader marketplace and Prime's established benefits.

What's Next for Walmart and Amazon?

So, where do Walmart and Amazon go from here? The battle for affluent, time-pressed consumers is intensifying. Walmart is expanding premium offerings like BetterGoods and revamping its Great Value line to attract upscale shoppers. Meanwhile, Amazon is doubling down on grocery, trialing new delivery methods to close the gap.

Here's what matters: If Walmart can continue to enhance its offerings and take advantage of its physical presence while expanding its digital footprint, it might shift the balance of power in e-commerce. For now, both giants are gaining e-commerce market share, often at the expense of smaller retailers.

What the street is missing: The real competition may not be Walmart vs. Amazon, but how these titans will continue to innovate in e-commerce while others struggle to keep up. Could Walmart’s agile response to market demands eventually overthrow Amazon's long-held dominance? It’s a question that will keep industry watchers on their toes.
