The Quarter E-Commerce Stopped Losing Money

Earnings seasons usually slide past without rewriting the playbook. The Q1 2026 print did not. Three reports landed in a four-week window — Walmart on May 15, Amazon in late April, and Shopify's Q4 2025 report in early February with Q1 2026 guidance — and together they describe a structural shift that operators are still pricing in.

Walmart's U.S. e-commerce business, after roughly a decade of investment, posted its first-ever profitable quarter. Amazon beat earnings expectations by ~60%, with AWS growing at its fastest pace in 15 quarters and an advertising business that has quietly crossed $70 billion in trailing-twelve-month revenue. Shopify guided to another quarter of ~30% revenue growth, with a B2B segment whose GMV nearly doubled year over year. None of these prints, in isolation, was the story. Read together, they are: the unit economics of online retail have crossed over.

This piece is a tour through what the prints actually said, why the timing matters, and — for an operator running a Shopify store — what changes about how you should be thinking about cost, channel mix, and growth for the rest of 2026.

1. Walmart's Crossover Quarter

The Walmart number that mattered was not the headline 21% U.S. e-commerce growth — that is in line with where the business has been running. The number that mattered was the parenthetical. CEO Doug McMillon, on the May 15 call, said the U.S. e-commerce business is now profitable. That sentence ends a roughly decade-long subsidy. From the 2016 Jet.com acquisition through the build-out of store-fulfilled pickup, the company's digital business operated as a strategic loss line, paid for by the still-massive in-store P&L while infrastructure caught up.

What flipped the sign is unglamorous. Sub-three-hour deliveries grew 91% year over year in Q1, and roughly a third of all store-fulfilled deliveries now arrive in that window, per Progressive Grocer. Pulling fulfillment out of distribution centers and into the existing store footprint dropped the last-mile cost curve. Third-party marketplace sellers — who have ramped meaningfully on Walmart.com over the last two years — contributed margin without consuming inventory capital. And the advertising business, Walmart Connect, grew 31% in the quarter. That ad growth is the part most worth dwelling on. Retail-media revenue carries operating margins north of 70%, which means the marginal dollar from Walmart Connect cleanses the marginal dollar from the rest of the digital P&L.

The Canadian print added a useful read-across. Walmart Canada delivered net sales of $6.3 billion, up 5%, with e-commerce growing 31%, led by store-fulfilled pickup and delivery. Same playbook, smaller geography, same direction.

2. Amazon's Three Profit Engines

Amazon's Q1 was the cleaner narrative. Revenue of $181.5 billion grew 16.6% year over year. EPS came in at $2.78, against a consensus of $1.73 — a ~60% beat, per the VAR Q1 roundup. The story underneath the beat is that the three high-margin engines all printed simultaneously, and the retail business kept the lights on while they did.

AWS grew 28% year over year, its fastest pace in 15 quarters. The AI workload tailwind, which everyone has been narrating for two years, is now showing in cloud-segment growth at scale. Advertising generated $17.2 billion in Q1, up 22% YoY, and crossed $70 billion on a trailing-twelve-month basis, per Adweek. That puts Amazon Ads at a scale that rivals YouTube's standalone ad business, and the segment continues to grow faster than the rest of digital advertising. Grocery — the slower-burn category Amazon has been working at for nearly a decade — disclosed $150 billion in gross 2025 sales, with Andy Jassy explicitly framing Amazon as the second-largest grocer in the United States.

The detail worth pulling out, for non-Amazon merchants: third-party seller performance was called out as a Q1 driver. The March Big Spring Sale ran particularly strongly for 3P sellers, and a 31% surge in Sponsored Brand video ad adoption among mid-market sellers contributed to ad growth. Translation: even on the world's largest first-party retailer, the marginal growth is leaning into the 3P + retail-media combination — the same combination that made Walmart's quarter print profitably.

3. Shopify's Quiet B2B Pivot

Shopify is a quarter earlier in the calendar, but its Q4 2025 print (reported February 2026) and Q1 2026 guidance fit the same arc. Q4 2025 revenue was $3.67 billion, up 30.6% year over year. FY2025 revenue grew 30%. The genuinely new line item: B2B GMV grew 96% in FY2025 and 84% in Q4 2025, per Digital Commerce 360 and the Shopify Q1 2026 release.

That growth is being driven by two flows. The first is large wholesale brands signing up net-new — Sonepar, the international electrical distributor, and Sunin, a century-old industrial manufacturer, are the canonical examples Shopify has cited. The second, more interesting flow is existing D2C merchants moving their B2B side onto the platform, so wholesale and consumer run on the same OMS, the same product feed, the same customer profile. Shopify has been clear that B2B is still a small share of total platform GMV — but it is the fastest-growing share, and the take rate dynamics are different enough that they show up disproportionately in operating leverage.

For Q1 2026, Shopify guided to low-30% revenue growth with gross-profit-dollar growth in the high 20s and free-cash-flow margins in the low- to mid-teens. The shape of that guidance — top-line growth still accelerating, gross profit dollars compounding, FCF margin holding double digits — is what a platform looks like when its mix is steadily shifting toward higher-leverage surfaces. B2B, Shop Pay, capital, and the agentic-commerce surfaces are all part of that shift.

4. Three Things The Prints Have In Common

Strip the three reports down to the shared signal, and the common thread is that the high-margin layer of e-commerce is now compounding faster than the low-margin core. Retail media, AWS, third-party seller fees, B2B GMV — these are the lines growing 20% to nearly 100%. The first-party retail layer is still growing, still very large, and increasingly serving as the distribution rail for the higher-margin layer on top of it.

Second commonality: fulfillment infrastructure has become a profit center rather than a cost center, at scale. Walmart's same-day store-fulfilled network turned the unit economics positive. Amazon's regionalized fulfillment, combined with same-day delivery in aggressively expanded markets, kept retail-segment margins from leaking even as advertising and AWS drove the beat. The throughline: scale operators have figured out how to make density and speed pay for themselves. The mid-market has not yet — which is the operational gap that 3PLs, Shopify Fulfillment Network partners, and merchant collectives will spend the next 24 months trying to close.

Third: third-party seller models keep eating share. Walmart's marketplace is now meaningfully contributing to digital profitability. Amazon's 3P seller services line continues to outgrow the 1P retail line. Shopify's entire economic model is a third-party seller architecture. Marketplace and direct-merchant economics are converging — the same SKU is increasingly available through five surfaces, and the platform that owns the cleanest version of the inventory and review data is the one that captures the agentic-commerce traffic on top of it.

5. What Changes For A Shopify Merchant

If you are running a $1M–$50M Shopify store and reading the three earnings prints, three things should change in your 2026 plan.

First, treat retail media as a primary margin lever, not an experiment. The same Walmart Connect / Amazon Ads dynamic that lifted those P&Ls is now accessible to mid-market merchants through Shop campaigns, Meta Advantage+, and a maturing set of TikTok Shop and Pinterest ad surfaces. If a 70%-margin ad dollar is showing up at the top of your funnel and you are only running performance media at the bottom, you are leaving operating leverage on the table.

Second, look at B2B seriously. Shopify's B2B GMV nearly doubled in FY2025. If your product is something any other business might resell — wholesale apparel, consumables, supplies, branded merch — turning on Shopify's B2B surface is the highest-leverage product expansion you can run in 2026. The acquisition cost on B2B accounts is meaningfully lower than D2C, average order values are 5–10x larger, and the contribution margins after fulfillment are usually stronger.

Third, get serious about fulfillment density. You cannot replicate Walmart's same-day-store network, but you can choose a 3PL footprint that places inventory in two or three demand-weighted regions instead of one, you can adopt zone-skipping where it makes sense, and you can publish accurate machine-readable shipping times on every product page. The agentic-commerce point we wrote about last week connects directly here: AI agents weight shipping reliability and stock truth heavily, and the merchants with the best fulfillment data feeds get disproportionately surfaced.

6. What The Q1 Prints Did Not Say

It is worth being honest about what these three earnings reports did not prove. They did not prove that small or mid-market e-commerce is broadly profitable. Walmart's profitability print was an enterprise milestone after enormous capex; mid-market merchants are running with very different fulfillment, ad-tech, and marketplace economics. Amazon and Shopify both serve millions of merchants, many of whom are still struggling on contribution margin. Aggregate platform growth is not the same as broad-based merchant health.

The prints also did not address the demand-side question that overhangs everything else: how durable is consumer spending in the back half of 2026? Walmart called out tariff-related cost pressure as a watch item. Amazon's grocery momentum reflects a continued trade-down dynamic. A softer consumer environment in Q3 or Q4 would land hardest on the merchants who do not yet have the retail-media or B2B margin layer to absorb it.

So the right read is not "e-commerce is fixed." The right read is "the model for what a profitable e-commerce business looks like in 2026 has been demonstrated at scale, and the components of that model are progressively more accessible to mid-market operators." That is a useful distinction, because it tells you which investments — retail media, B2B, fulfillment density, agent-ready product data — are most likely to compound through whatever the rest of the year looks like.
