Flipper Vantage reveals ‘What’s it worth?’ and ‘Where does it sell for the most?’

Flipper Vantage is a database of 300M+ real sold resale listings, actual sold prices (not listing prices), across eBay, Depop, Grailed, Poshmark, Mercari, Vinted, Vestiaire and StockX. The findings are that the best place to sell depends entirely on the item. A Supreme Box Logo hoodie sells highest on Grailed, not eBay.

Streetwear, workwear and designer each have their own best venue, and the gaps are big. Flipper Vantage can show the best marketplace for any given item straight from real sales. Menswear and streetwear: Grailed pays roughly double. Same used Nike, $24 median on Poshmark versus $55 on Grailed. Champion +167%, Adidas +127%, Carhartt +120%.

Luxury: A completely different order. Chanel is a $1,140 median on Vestiaire and $53 on Mercari. Speed: Half of Poshmark items sell in 15 days, eBay 18 days, Grailed 22 days. Poshmark is the fastest major venue, Grailed the best-paying, and you generally pick one or the other.

The exception that proves it: Supreme sells for about the same on both ($88 vs $85). Hype travels; almost nothing else does.

There are some limitations, data is based on US marketplaces, there are no sell-through claim (Flipper Vantage only see what sold), sell-speed is measured only where the marketplace gives real dates, and brand-level isn’t the identical garments so part of the gap is item mix.
