Global Apparel Resale Market Projected to Hit $338.4 Billion in 2026
New reports confirm the global apparel resale market will reach $338.4 billion this year, with two independent research firms validating this massive growth trajectory.

Kearney Index Positions Environmental Regulations as Brand Value Drivers
Kearney’s 2026 Circular Fashion Index highlights that environmental regulations can create tangible value for brands rather than just imposing costs. The report pushes companies to leverage sustainable practices as competitive advantages, suggesting that early adopters of circularity are better positioned to navigate regulatory landscapes and appeal to eco-conscious consumers.
SLY Collective Identifies Key Sustainable Fashion Trends for 2026
SLY Collective released a report outlining ten major shifts from 2025 that are reshaping sustainable fashion in 2026, including the rise of circular models, enhanced traceability, and the integration of recycled fibers. These trends signal a move away from superficial green marketing toward structural changes in supply chains and consumer engagement.
Resale & Secondhand Market
The resale sector continues to dominate headlines with robust growth metrics. The confirmation of the $338.4 billion valuation for 2026 underscores the scale of this shift, with platforms like ThredUp, Depop, and Poshmark driving mainstream adoption.
While specific platform updates for the past week were limited in the immediate search results, the broader market context shows that resale is tracking toward a projected $448 billion by 2029, according to earlier data cited in recent industry discussions. The current momentum suggests that the 2026 figure is on track or potentially exceeding expectations due to sustained Gen Z interest.
