Tradera.com is an online marketplace based in Stockholm, Sweden. With its 3,6 million members, 6 million weekly visits and more than 3 million listings at any given point (2024), it's the largest marketplace in the Nordics for sustainable shopping. Items are sold from both private consumers and businesses and are ranging from fashion and interior design to tech and collectibles. Although Tradera welcomes members from all over the world, most are from within the EU and Sweden. Tradera was originally based completely on auctions, but today visitors can purchase both new and second hand items through auctions as well as fixed price listings. Tradera was founded in 1999 but was acquired by eBay Inc. in 2006, which already owned the financial tech company PayPal. When eBay and PayPal were separated in 2015, Tradera became part of PayPal. Since PayPal's sale of Tradera in 2021, Tradera has once again become a Swedish company.
