Walmart Marketplace Momentum Pressures Brick-and-Mortar Limits, With U.S. Sales Jumping 52%, Report Says

Walmart’s marketplace model is gaining momentum again, according to a recent market report that points to fast-growing sales from third-party sellers. The article says Walmart’s U.S. marketplace sales rose 52% and argues that broader product assortment, increased adoption of Walmart’s fulfillment services, and geographic expansion into Mexico and Canada are reinforcing the platform’s growth engine.

Marketplace sales refer to transactions where Walmart hosts products from external sellers and the customers buy through Walmart’s online channels. Instead of carrying every item itself, Walmart can offer a wider catalog while taking fees tied to sellers’ commerce, which can be attractive when consumer demand shifts quickly to new products. In the report, the company’s ability to scale assortment and keep the shopping experience consistent is presented as a key reason for the pace of growth.

The report also links acceleration to more sellers using Walmart’s fulfillment network. Fulfillment services are the logistics layer that handles picking, packing, and shipping for customer orders. When third-party sellers send inventory to Walmart, the retailer can standardize delivery times and manage returns more efficiently than if sellers ship independently, which can improve conversion and repeat shopping.

Another pillar in the article is expansion beyond the U.S. It says Walmart’s marketplace momentum is being reinforced through growth in Mexico and Canada, markets where the platform is still scaling relative to its U.S. footprint. For investors and analysts, cross-border growth matters because the underlying marketplace technology can be leveraged across regions, even as operating costs and seller onboarding remain in transition.

Walmart has framed its larger retail strategy as one of building stronger omnichannel capabilities, where online order handling, store inventory, and third-party participation support each other. A marketplace that can grow faster than traditional assortment can also help lift engagement during periods when consumers are price-sensitive and product variety becomes a differentiator. In that context, marketplace acceleration can become a measurable announcement of whether Walmart’s investments in technology and logistics are translating into demand.

At the same time, the marketplace model brings its own performance questions that Walmart has to manage continuously. Platform growth depends on attracting a steady supply of sellers and keeping product quality and delivery performance consistent. If delivery times slip, return rates rise, or category-level assortment gaps emerge, the marketplace can stall even if top-line platform traffic continues.

The report does not provide a detailed breakdown of what drove the 52% U.S. marketplace increase, beyond pointing to broader assortment, fulfillment adoption, and expansion. It also does not state whether the growth translated into specific changes in take rates, operating margin contribution, or the mix between seller-shipped and Walmart-fulfilled orders. Walmart typically discloses financial results at the company level, so readers should treat any marketplace-specific inference as directional until the company publishes more granular commentary.

What to watch next is whether Walmart can sustain the momentum without eroding customer experience. The most relevant indicators are continued marketplace sales growth, evidence that fulfillment adoption is rising in step with seller participation, and further milestones in Mexico and Canada that suggest the platform is reaching scale. If Walmart begins to emphasize marketplace metrics more directly in future updates, it could also clarify how much of the growth is structural versus temporary category or seasonal effects.
