AI and Influencers Propel Global Secondhand Clothing Market Toward $289 bn Forecast

Forecasts indicate that the worldwide secondhand apparel sector will expand by 12% in 2024, reaching $289 bn (£217 bn), buoyed by artificial intelligence tools and social‑media influencers that help consumers locate desired items.

Platforms such as Vinted, Depop, Vestige and ThredUp are expected to sustain an average 9% annual growth over the next five years, pushing the market to an estimated $393 bn—roughly double the growth rate of the broader clothing industry.

The outlook stems from ThredUp’s latest resale report, which incorporates analysis from GlobalData. In 2021 the market was valued at just $141 bn, meaning the projected 2024 figure is more than double that baseline.

Major brands—including Dr Martens, Zara and Mulberry—are now entering the resale space, either by offering pre‑owned pieces or refurbishing items to satisfy rising consumer demand.

"Resale is no longer merely expanding; it’s capturing direct market share," said James Reinhart, co‑founder and CEO of ThredUp. The report notes that resale now accounts for one‑tenth of global clothing sales, and that the U.S. secondhand market grew nearly four times faster than the overall market by 2025.

ThredUp’s own revenue climbed 20% to $310.8 m last year. Depop reported a 42% increase to £101 m, while Vinted posted a 36% rise to €813.4 m (£710 m) in 2024. However, profitability remains elusive: ThredUp posted a $20 m pre‑tax loss, Depop a £42 m loss, and only Vinted turned a profit, earning €76.7 m. Depop was recently acquired by eBay from Etsy.

Reinhart warned that rising inflation—spurred by geopolitical tensions that lift energy and fuel costs for manufacturers—could push more shoppers toward affordable secondhand options.

"The industry stays robust, driven by young consumers' behaviour," he added.

Artificial intelligence is streamlining the massive inventories of resale platforms, enabling rapid cataloguing and matching of items to buyer preferences. "Netflix and Spotify spent decades building data and algorithms to recommend content; AI can achieve similar personalization for fashion almost instantly," Reinhart explained, noting that this reduces friction between spotting an item on social media and completing a purchase.

Looking ahead, the market’s next phase will be defined by firms that can unlock supply and leverage AI to connect inventory with the next generation of shoppers, according to Reinhart.

Analyst Neil Saunders of GlobalData highlighted that consumers aged 14‑45 (Gen Z and millennials) are projected to generate 70% of market growth. He emphasized that discovery tools must migrate to the social feeds where these shoppers spend their time, and that technology will be essential to simplify selling and maintain sufficient stock for expanding demand.
