Recommerce in 2026: the secondary market is no longer a side channel

Somewhere in the last few years, buying second-hand stopped being a compromise. It became a default option, and in some categories the first one people check.

That change rarely appears in a retailer's reporting as growth in someone else's market. It appears as a softening conversion rate with no obvious cause. Our desk research on second-hand commerce suggests those are often the same event seen from two sides.

What recommerce means

The term comes from reverse commerce. Products return to the market through resale, renewal, or C2C and peer to peer marketplaces such as Vinted, eBay or Zalando's pre-owned section. In practice it covers four channels: online second-hand marketplaces, local selling groups (mostly on Facebook Marketplace), brand buyback and trade-in schemes, and resale platforms run by brands themselves.

What matters commercially is the function they perform. They lower price pressure, reduce the need to buy something new, and move the purchase decision outside classic B2C e-commerce. For a retailer watching only their own funnel, that looks like customer loss. It is closer to relocation.

The global picture

C2C trade is now a standard segment of global e-commerce rather than a curiosity. According to Statista, around 12% of internet users have bought a pre-owned product online, and in many countries a majority of consumers have bought something second-hand in the past year.

Fashion dominates the category without defining it. ThredUp's Resale Report 2025, prepared with data from GlobalData, puts the global second-hand apparel market on course to reach $367 billion by 2029, growing almost three times faster than the apparel market as a whole. Add furniture, electronics and toys, and Statista forecasts revenue approaching $448 billion across all second-hand categories by the same year.

The channel structure varies sharply by region, which is easy to miss from a single market's perspective. Marketplaces dominate everywhere, but which marketplace differs: eBay leads in Western markets with over 136 million buyers, while in China Xianyu, also known as Idle Fish, has more than 215 million active users. Vinted, Depop and Mercari remain the most downloaded C2C apps worldwide.

Why people buy used, and it is mostly not thrift

ThredUp's survey of US consumers ranks five reasons for buying second-hand: getting better deals, the thrill of the hunt, being able to afford higher end brands, environmental reasons, and finding one of a kind pieces.

Three of those five have nothing to do with saving money. Price opens the category. Access and the experience of finding something are what keep people in it, which is a very different proposition to compete against than simple discounting.

Channel preference reinforces the point. In the US, peer to peer marketplaces lead at 31%, ahead of managed marketplaces, social media, and buying directly from a brand. The formats people prefer are the ones with the least selling done to them.

Resale value has entered the decision to buy new

This is the finding with the most direct consequence for anyone building an assortment. According to ThredUp, 47% of US consumers say resale value matters when they buy new clothes, rising to 64% among younger generations.

The effect lands first at the cheap end. Around half of US consumers say they have cut back on low quality clothing precisely because they cannot resell it, and most say they would pay closer attention to quality if they knew an item's resale value at the point of purchase.

Which moves durability and repairability out of the sustainability slide and into the commercial argument.

Social platforms became a sales channel

Second-hand and social commerce converged faster than most retailers planned for. ThredUp found that 39% of younger US shoppers bought second-hand clothing through a social commerce platform in the previous 12 months, against 28% of consumers overall.

The motivation is partly about visibility rather than acquisition. Half of younger buyers said they bought second-hand in order to create content or share the purchase, a reason neither price nor sustainability explains. Facebook Marketplace leads the platform ranking, followed by Instagram, TikTok Shop, YouTube and Pinterest.

Luxury changed its mind, and AI is the reason why

For years luxury brands stayed out of resale deliberately. In a McKinsey Podcast episode published in June 2026, senior partner Gemma D'Auria named the three reasons: brand dilution, the difficulty of guaranteeing authenticity, and loss of control over the end to end experience.

Two things changed. Resale gave value oriented buyers access to what McKinsey calls aspirational luxury, and it answered a demand for uniqueness the primary market struggles to serve. On the supply side, resale platforms scaled and AI brought the cost of authentication down significantly, which made resale viable in categories where it previously was not. Brands are now actively looking at how to partner with platforms and curate what their customers see there.

AI is doing similar work on the demand side. Second-hand has a structural discovery problem: every item is unique, descriptions are inconsistent, and sizing cannot be trusted. Four in ten US consumers told ThredUp they feel overwhelmed by the volume of items available, rising to 53% among younger generations. Better search and recommendations appear to close that gap, and the substitution effect is already measurable: 46% of US consumers say that if they can find an item second-hand, they will not buy it new.

Three ways for a brand to participate

Shopify describes three basic structures. In C2C, the platform only connects individual buyers and sellers, which means the lowest operational load and the least control. In consignment, the marketplace takes ownership of goods, photographs them, creates listings and fulfils orders. Trade-in works similarly but pays the seller upfront, which makes it the strongest acquisition tool and the most demanding on working capital.

Some brands run resale themselves. Patagonia, Diane von Furstenberg and Levi's all operate their own second-hand marketplaces, which lets them earn from resale and control how their products are presented. Which allows them to avoid one of the biggest trap in reselling: fake or inaccurate listings shape brand perception even when the brand never touched the transaction.

What this means for online retailers

Read alongside our own research from December 2025, recommerce stops looking like a sustainability story and starts looking like a structural one. Our respondents described fatigue with online shopping: too many offers, too many messages, too much decision pressure, and a growing preference for processes that ask less of them. The secondary market answers that directly.

Three consequences follow.

Resale value belongs in the product proposition. If nearly half of consumers already weigh it when buying new, durability and desirability on the secondary market are commercial arguments, not CSR ones.

Predictability beats pressure. Our research found that the heaviest buyers reduce their online purchases not because of price but because they lose the sense of control over the decision. Excessive personalisation, artificial promotions and pressure mechanics push them towards closed, predictable ecosystems. Resale platforms benefit from being comparatively quiet places to shop.

Presence on the secondary market is a choice about control. A brand that stays out of resale does not stay out of the secondary market. It only loses influence over how its products are described, authenticated and priced there.
