Retailers are taking a page from Amazon’s online stores playbook—but with a twist. Over the last year, specialty retailers Lowe’s (December 2024), Best Buy (August 2025), and Ulta Beauty (H2 2025) have each unveiled their own third-party marketplaces. This new wave of curated third-party marketplaces isn’t about becoming the so-called “everything store” like Amazon. Instead, it’s an opportunity for retailers to expand their product selection without the headache of holding inventory, offering shoppers more choice while keeping the brand experience tightly controlled. Overall, this seems to be part of a broader bet that owning the marketplace layer means owning more of the assortment, monetization, and discovery game, two retail analysts told Retail Brew. According to eMarketer’s latest forecast, US e-commerce marketplaces have surpassed 40% penetration and are projected to exceed $500 billion in sales in 2025, with total marketplace sales expected to surpass $700 billion by 2029. While Ulta, Lowe’s, and Best Buy are not exactly going head to head, each of the retailers now has a fresh growth lever to pull. As customers get more comfortable shopping at marketplaces, there’s a long line of merchants who could use the opportunity to get their products in front of shoppers via these platforms. “Each of these companies wants to ensure that they aren’t missing sales because they don’t have some very specific item that somebody might want,” Zak Stambor, senior analyst for retail and e-commerce at eMarketer, told Retail Brew. “That’s the objective.” By partnering with a vendor like Mirakl, Stambor said, expanding product assortment would be a “fairly light lift” for these retailers.
