Resale Business in 2026: Platform Fees, Sourcing, and What Actually Sells

The secondhand market worldwide is approaching $400 billion, surpassing the growth of traditional retail. Increased tariffs on new products have led to a broader price disparity between retail and resale, driving more consumers toward secondhand options. Full-time sellers are now supported by resale, with their success hinging on factors like platform selection, sourcing, taxes, and the categories they choose. eBay takes a 13.25% fee, while Poshmark charges 20%, Mercari 10%, and Depop 3.3% plus $0.45. After a sale, sellers must remove cross-listed items. Effective sourcing from thrift shops and estate sales is essential. Tax obligations arise early, as profits are taxable irrespective of 1099-K limits. By 2026, popular resale categories will likely include terrace-style sneakers, vintage denim, designer handbags, and refurbished electronics. Pricing should reflect sold comparables, item condition, and platform fees.
