Resale platforms are grappling with the best sort of problem to have: how to manage a surge in new shoppers.
While US trade policies roil the fashion industry at large, resale is welcoming a flood of âtariff-iedâ new customers. On Monday, resale marketplace ThredUp reported that the number of new buyers on its platform in the first quarter rose 95 percent compared to last year, marking the largest quarterly increase in new customers in the companyâs history. ThredUpâs stock is up more than 40 percent after its first quarter beat Wall Street expectations, with revenue rising 10 percent year over year to $71.3 million. On the other end of the spectrum, luxury resale is also faring well with TheRealReal reporting revenue up 11 percent year over year to $160 million on Thursday.
The jump in new shoppers aligns with data from marketing intelligence firm Sensor Tower, which found downloads of resale apps in the US rose during the first quarter of 2025, with Depop, Vestiaire Collective, Poshmark and eBay among those seeing the most significant growth. While resale has other tailwinds, like more consumers trading down and looking for deals after a long period of inflation, the anticipation of higher costs on new apparel from tariffs appears to be driving more interest in secondhand shopping.
âAs we look ahead, weâre cautiously optimistic that resale and our business could benefit,â ThredUp chief executive and co-founder James Reinhart told The Business of Fashion.
The closing of the de-minimis loophole last week has simultaneously eroded the value proposition once held by ultra fast-fashion labels such as Shein and Temu, which have already seen sales decline with their introduction of higher prices. Poshmark CEO Manish Chandra believes as those products become more expensive, shoppers will naturally gravitate towards resale.
âThe great thing about this inventory is most of it already exists in the country,â Chandra said of resaleâs offering.
Secondhand platforms are generally less reliant on products from overseas sources like China, meaning tariffs arenât a major concern. Ebay said in its earnings call last month that only 5 percent of its global merchandise value goes from Greater China to the US. Depopâs parent company, Etsy, shared on its recent earnings call that just over 1 percent of gross merchandise sales were attributed to US imports of items from sellers in China.
But with new growth comes new problems to solve. Resale businesses are competing against each other to attract sellers, whose inventory they need, and as platforms scale and fill up with more users and products, it can become harder for buyers to find exactly what theyâre looking for or diminish the sense of curation that may have attracted early users. The user experience can suffer as a result, turning off customers old and new.
For sellers, changes to selling fees and commission or even where they can list items can create gripes that may push them to sell inventory to other platforms. Last week, Modern Retail reported that sellers on Poshmark were suspended after they were accused of âexcessivelyâ deleting and relisting items to bump up their visibility to shoppers.
âItâs not a supply problem,â said Andy Ruben, a senior advisor for Boston Consulting Group who previously founded the branded resale platform Trove, âwe have a trust challenge, we have a model challenge and we have a visibility challenge.â
The Innovation Flywheel
Companies can dodge some of these issues by carving out a niche within the market, as ThredUp has according to Dylan Carden, a consumer research analyst for William Blair. Where many other marketplaces are focused on either peer-to-peer resale or luxury fashion, ThredUp has found a lane for itself by focusing on womenâs and kidâs clothing collected through a consignment model that specialises in mainstream high-street brands such as J. Crew, Lululemon and Theory, which also grants ThredUp a higher take rate because sellers have lower expectations for an itemâs value â and their cut of it â than in luxury.
Many resale businesses have also been looking to technology for help as the secondhand market has grown rapidly in recent years. Ebay uses AI to make it easier for sellers to list items and on Tuesday unveiled a shopping agent that helps shoppers discover listings through uploading a photo or speaking with an AI chatbot about an item theyâre searching for. Poshmark introduced an AI-powered listing tool in January that it claims cuts the time for sellers to post listings by 48 percent. On ThredUpâs earnings call on Monday, Reinhart said customers who used an AI-powered âshop similarâ search tool during a session had a 64 percent higher conversion rate.
Reinhart told BoF that ThredUp began a âreally aggressive AI-development processâ at the beginning of 2024 and has launched new AI-assisted tools nearly every quarter to improve ThredUpâs product experience, which in turn increases its conversion rates and customer acquisition.
âThe final piece is that it gives you the flexibility and the incentive to then process lots of great products that are in season and on-trend,â said Reinhart. âThat combined with an ever-improving, AI-based product experience is whatâs driving the flywheel in the business.â
Platforms such as eBay allow shoppers to save searches to make browsing easier, but the difficulties for consumers arenât just limited to scouring one site. Finding the product youâre looking for or comparing deals can often require searching on numerous sites. The app Phia, which was co-founded by Bill Gatesâ daughter Phoebe, aims to tackle part of the problem by offering price comparisons of products across sites. Another app, Gem, tries to make it possible to search a variety of resale marketplaces in one search bar.
Founder Liisa Jokinen created Gem in 2019 to address how hard it had already become to sift through the number of secondhand platforms available. Jokinen is acutely aware of how saturated these marketplaces can become, with Gem currently presenting searchers 125 million listings as of this week.
âSome old shoppers or users might feel that if there are more secondhand shoppers, there will be more demand and more competition, so they might feel like they canât find the good items and good deals anymore,â said Jokinen.
The Branded Resale Opportunity
Dedicated resale businesses arenât the only ones eyeing the surge in secondhand shoppers. More brands and retailers in the primary market have been looking for a share of resale in recent years, and now thereâs only more incentive to get in on the action.
âYes, marketplaces are going to be advantaged, but brands are also now moving up the priority of resale,â said BCGâs Ruben. âThe risk and the headwind that these marketplaces will now face is when brands and retailers get serious about the space.â
By relying on customers domestically to provide used inventory, brands would be able to avoid tariffs on those items and soften the blow from tariffs on the new goods theyâre importing.
Branded resale as a service is already offered by both Poshmark and Thredup, which have forged partnerships with brands such as Reformation to help their customers easily resell used goods. ThredUpâs Reinhart also singled out branded resale as a larger opportunity on the companyâs earnings call Tuesday, announcing that ThredUp plans to open-source its technology and logistics to help brands build resale businesses through free branded shops and simplified clean-out programmes.
âGiven volatility in global trade, itâs probably more relevant than ever for a brand to think about how to get back products or recycle them into their supply chain to not pay tariffs on stuff itâs already made,â said Reinhart.
Of course, brands themselves could instead choose to build out their own branded resale programmes independently and challenge these marketplaces.
âThe [customer] pipeline has never looked like this,â Ruben said. âBrands and retailers getting serious is a long term competitive challenge for them.â
In the meantime, theyâll be doing what they can to attract â and keep â all the new shoppers that tariffs are sending their way.
