Walmart is doubling down on its mission to challenge Amazon’s dominance in the e-commerce space, announcing a strategic partnership with JPMorgan Chase on this week, to accelerate payments for sellers on its marketplace platform. The move is part of a broader effort to enhance its online shopping ecosystem, attract more sellers, and close the gap with its Seattle-based rival, which has long held the crown in U.S. online retail.
The collaboration between Walmart and JPMorgan Chase aims to streamline financial operations for the 100,000 sellers on Walmart’s marketplace, which offers over 700 million items ranging from beauty products to electronics. According to Lia Cao, head of embedded finance and solutions at JPMorgan, the partnership will allow merchants to accept and make payments while managing cash flow more efficiently using the bank’s systems. This is a significant draw for sellers, who often face delays in payment processing on other platforms—a pain point Walmart is keen to address as it competes for Amazon’s seller base.
Walmart’s marketplace has been gaining momentum, with sales surging 40% in the fourth quarter of 2024, a sign that its investments in e-commerce are paying off. The retailer has been aggressively building out its online infrastructure to rival Amazon, including bolstering its Walmart+ membership program. Launched in 2020, Walmart+ offers perks like free shipping, fuel discounts, and a complimentary Paramount+ subscription, positioning it as a direct competitor to Amazon Prime. By sweetening the deal for sellers with faster payments through JPMorgan, Walmart hopes to lure merchants away from Amazon.
The partnership taps into the growing trend of embedded finance, where financial services are integrated directly into business platforms. A McKinsey report estimates that over $2 trillion in transaction volume will shift to marketplace platforms like Walmart’s in the coming years, moving away from traditional retail models. JPMorgan sees this as a major growth opportunity, with Cao noting that the bank already has over 20 embedded finance partnerships and expects that number to double within the next year. While the service is currently available only to U.S. merchants, discussions are underway to expand into Europe and other regions, potentially broadening Walmart’s global reach.
This move comes at a critical time for Walmart, which has been steadily closing the gap with Amazon in online sales. In 2024, Amazon held a 37.6% share of U.S. e-commerce sales compared to Walmart’s 6.4%, according to eMarketer, but Walmart’s growth rate has outpaced Amazon’s in recent quarters. By improving its seller experience and enhancing its digital offerings, Walmart is signaling that it’s not just playing catch-up—it’s aiming to redefine the e-commerce landscape. For sellers, the promise of faster payments and better cash flow management could be a game-changer, but whether it’s enough to dethrone Amazon remains to be seen.
