The booming luxury resale market is expected to increase by 56% to $50 billion in the U.S. by 2030. “The Luxury Resale Market Research Report 2025-2030” traces the growth to several factors, including consumer preferences for unique items over mainstream brands; partnerships between platforms and brands, including one between ThredUp and Rebag; and the growth of e-commerce and online resale platforms. Women are primary growth drivers because of demand for high-value fashion, while Gen Z and millennials are the “most influential” groups driving innovation and expansion because of their demand for sustainable fashion. Counterfeit products remain a significant issue.
