Gen Z’s obsession with secondhand clothes is paying off for eBay as its fashion sales with Depop hit $9 billion over the past year

eBay reported Q3 gross merchandise volume of $23.2 billion, up 15% year over year (nearly 16% excluding currency effects), with Depop contributing nearly three percentage points to growth. Depop’s U.S. sales volume more than doubled year over year in Q3, and its active buyers reached 11 million over the trailing 12 months, up from 9 million. eBay acquired Depop for $1.4 billion in July and is investing more in its marketing and exploring ways to surface Depop listings to eBay shoppers.

Analysis

The investable question is not whether resale demand is growing, but whether eBay can convert Depop’s activity into durable, profitable transactions. More listings and repeat use can improve marketplace liquidity and reduce buyer acquisition friction; eBay’s shipping and cross-promotion capabilities may help. But GMV growth is not earnings growth: incremental marketing, seller incentives, returns, and integration costs could absorb the benefit. Verify Depop’s net revenue, take rate, contribution margin, and customer-acquisition costs before capitalizing its growth.

Competitive pressure is asymmetric. Brand-run resale can retain customer data and capture transactions that might otherwise reach marketplaces, but it also requires brands to operationalize authentication, logistics, and fragmented used inventory. Levi Strauss may gain engagement and resale-channel control, while risking substitution of new-product sales; the net effect is unproven. ThredUp is exposed to the same category tailwind, but eBay’s ability to cross-sell across a broader marketplace could make growth quality—not category exposure—the differentiator.

Near term, avoid extrapolating a strong quarter into a valuation re-rate absent margin evidence. Over 1–3 months, watch eBay’s next results for fashion growth, marketing intensity, and whether cross-platform discovery increases completed transactions. Over 6–18 months, the structural upside depends on repeat seller/buyer behavior and profitable liquidity. The contrarian risk: affordability-led resale may be cyclical, while sustainability survey responses need not translate into monetizable demand.

Key Decisions for Investors

• EBAY: Favor a measured long on weakness rather than chasing the post-earnings narrative. Reassess after the next report; require evidence that Depop’s growth is contributing to transaction revenue and operating economics, not only GMV.
• Falsify the EBAY thesis if subsequent results show fashion/Depop activity decelerating while marketing or fulfillment costs rise, or if management indicates cross-platform discovery is not improving conversion or repeat use.
• Do not short TDUP solely because eBay is gaining traction: the article does not establish relative unit economics or share losses. Compare take rates, contribution margins, cash burn, and customer retention before considering a pair trade.
• Treat LEVI resale as strategically ambiguous, not automatically accretive: monitor whether resale expands customer reach without weakening new-product sell-through or gross-margin mix.
