Depop's Inventory Scarcity Limits Growth

Depop’s ceiling is set less by buyer demand than by how many great items individual people are willing to list. Unlike first hand marketplaces that can add unlimited stock from brands or merchants, Depop depends on millions of closet cleanouts producing enough vintage, streetwear, and trend right pieces to keep feeds fresh. That makes supply quality the core bottleneck, which is why fee cuts, listing tools, and brand archive drops matter so much.

• Depop already shifted from a 10 percent seller fee to buyer fees in 2024, specifically to pull more sellers and listings onto the app. That move shows supply is scarce enough that lowering listing friction is strategically more important than maximizing seller monetization.

• Vinted shows one path past this constraint, it widened beyond fashion into adjacent secondhand categories and reached €813.4M revenue in 2024 with €95M net profit. Category expansion matters because a pure fashion feed can run out of enough desirable inventory faster than a broader resale marketplace.

• Other recommerce markets hit the same wall. Back Market’s research notes tightening refurbished smartphone inventory, and its response has been to add OEM and carrier supply partners. Depop is trying the fashion version of that with DKNY archive drops and potential authentication for higher value items.

The next phase of fashion resale will favor platforms that can manufacture supply, not just demand. That means deeper seller tools, more off platform sourcing through brands and partners, and expansion into categories or price tiers where inventory can be made more predictable and trusted.
