Walmart’s transformation into a global e-commerce contender is no longer theoretical—it’s happening at full speed. As of mid-2025, the Walmart Marketplace has surpassed 200,000 active sellers, powered by the fastest onboarding rate in the platform’s history and according to recent data from Marketplace Pulse, 44,000 new sellers joined the platform in the first five months of 2025 alone, rapidly closing in on the 59,000 sellers added in all of 2024.
If this momentum holds, Walmart could welcome over 100,000 new sellers by the end of the year, nearly doubling the platform’s growth rate compared to 2024, when it expanded by 60% to reach 160,000 sellers. This explosive growth signals more than just numerical success—it marks a profound shift in strategy for the United States’ largest traditional retailer.
Historically known for its brick-and-mortar dominance, Walmart is increasingly positioning itself as a modern digital marketplace. This effort is being supported by a nationwide marketing campaign under the slogan “Who knew?” to reshape public perception of Walmart.com as a vibrant, discovery-driven shopping destination.
With over 500 million products now available online and via mobile, Walmart’s digital footprint is expanding at an Amazon-like scale. Notably, 95% of these listings come from third-party sellers, reflecting Walmart’s evolution from a traditional retailer to a full-fledged third-party marketplace platform.
Walmart opened its U.S. marketplace to international sellers in March 2021, and in just four years, the impact has been seismic. In 2025, nearly 60% of new sellers originate from China, which accounts for 34% of all active sellers on the platform.
This influx of global merchants starkly contrasts with Walmart’s traditional image. CEO Doug McMillon has repeatedly emphasized that "two-thirds of what we sell in the U.S. is made or grown in the U.S.," a message designed to reinforce its patriotic brand identity. However, while this remains largely true in Walmart’s physical stores, the online landscape tells a different story that resembles Amazon’s global seller ecosystem.
Walmart’s biggest challenge in 2025 isn’t attracting new sellers—that trend is already firmly in motion. The real test lies in maintaining quality control, brand integrity, and a consistent customer experience as the platform scales at breakneck speed.
Unlike Amazon, which spent over a decade building a robust infrastructure to support its marketplace, Walmart is undergoing an accelerated evolution, compressing years of expansion into a much shorter time frame. This rapid growth introduces operational pressures, including:
Balancing rapid onboarding with long-term trust will determine whether Walmart can sustain its digital growth without compromising the customer experience that has defined its brand for decades.
Walmart’s ace up its sleeve is its massive U.S. store footprint. With over 4,600 locations nationwide, the company is uniquely positioned to merge physical retail with its digital marketplace in a truly omnichannel experience.
By integrating services like store pickup, same-day delivery, and local fulfillment, Walmart offers a hybrid shopping model that Amazon and most e-commerce platforms cannot easily replicate. This physical-digital synergy is not only a logistical advantage—it’s also a brand differentiator that strengthens customer loyalty and retention.
As Walmart’s marketplace continues to expand, expect the company to focus heavily on:
Walmart is not just growing—it’s redefining retail leadership in the 21st century. As it scales its third-party marketplace, it has the opportunity to build a more curated, quality-first alternative to Amazon, powered by its international reach and domestic infrastructure.
