Meta launched Seller on Friday, a standalone iOS app for people who list on Facebook Marketplace. Announced by Tom Alison, head of Facebook, it is free, US-only, and restricted to users 18 and over. Android and a web experience are in testing.
Not a spin-out
Marketplace is not moving. Buyers keep browsing inside the Facebook app, and listings created in Seller sync there automatically along with existing listings, message threads and selling history. Seller is a seller-side companion aimed at people who list often enough that the buyer-facing interface gets in the way.
What's actually new
The AI that turns a product photo into a draft listing — title, description, category and a price benchmarked against similar items in your area — is not new; Meta shipped it inside the main Facebook app on March 12. What is new is bulk listing creation for multiple items at once, plus a Seller Home dashboard that surfaces packages to ship, buyers awaiting replies and listings that may need repricing. There is also a unified inbox threaded by item, inventory tools, performance insights covering views, clicks and message threads, and prepaid shipping labels with order tracking. Meta has not said which model powers any of it.
The scale
Meta says 430 million items are listed on Marketplace every month worldwide, across home decor, fashion, electronics and vehicles. Marketplace turns 10 this October. Third-party estimates put it above 1 billion monthly users, which would make it one of the three largest resale ecosystems anywhere.
Who this is aimed at
Sellers who cross-list. eBay has 130 million+ active buyers; Poshmark charges 20% on sales above $15 and Depop 10%, while Vinted charges sellers nothing and pushes fees onto buyers. Meta disclosed no fee changes with Seller. It is separately testing eBay listings inside Marketplace in the US, France and Germany, and DoorDash delivery of Marketplace purchases.
