Meta launched a dedicated app for Facebook Marketplace sellers on July 24, 2026. The app, called Seller, lets merchants manage listings, respond to buyers, and track sales without switching back to the main Facebook app. Tom Alison, Head of Facebook, announced the product and said an Android version is in testing.
The app includes a home screen that flags items requiring action, such as shipments due, buyer messages, and listings to reprice. Meta AI assists with listing creation, pulling titles, descriptions, price suggestions, and categories from uploaded photos. Sellers can also create multiple listings at once using a bulk listing tool.
Seller includes a unified inbox organized by item and a performance dashboard covering views, clicks, message threads, and completed sales. Meta described the broader strategy behind the product as “agentic” — AI that acts rather than just suggests.
“Facebook Marketplace turns ten this year,” Meta wrote in an official blog post. “What started as people buying and selling in Facebook Groups has grown into a destination where 430 million items are listed each month globally, and for many has turned into a side hustle, a small business, real income. Today, those sellers get their own app.”
Alison framed the Seller app as part of a wider effort to build standalone products for Facebook’s high-intensity users. “I think about these as things that complement the main app, and cater to the more high-intensity user communities,” he told The New York Times. “It’s very early. It’s experimental.”
Facebook Marketplace currently accounts for 51.19% of all social commerce activity worldwide. About 33% of small businesses in the U.S. sell on the platform, and one in three young adults on Facebook in the U.S. uses Marketplace daily. Meta does not take a cut of sales and monetizes the platform through advertising.
Alongside the Seller app, Meta rolled out Facebook Verified, a free identity verification system that lets users take a selfie to confirm they are real. A checkmark inside a white circle appears on verified accounts across Marketplace, Groups, and Facebook Dating. This differs from the paid Meta Verified blue badge.
The app poses a direct challenge to eBay, which charges sellers final value fees ranging from 13% to 15% plus fixed transaction costs. Meta’s ad-based model means sellers face no comparable transaction fees. Wall Street responded quickly: eBay shares fell 3.7% on the day of the announcement.
The Seller app also addresses a retention problem. As merchants on Marketplace grew their businesses, many migrated to platforms with more robust tools. By building out a dedicated seller experience, Meta is competing to keep those merchants on its platform rather than losing them to eBay or other marketplaces.
The social commerce market is valued at $2.11 trillion in 2026, and TikTok Shop is projected to reach $23.41 billion in U.S. e-commerce sales this year, a 48% year-over-year increase. Meta’s move signals the company intends to compete directly for that volume. Alison said the company will continue to update the app based on seller feedback.
