StockX vs Whatnot: Where to Sell Sneakers and Trading Cards
Which items suit each, what each takes from a sale, StockX's new live marketplace, and how to run both without selling twice.
7 days for £1, then from £9/month.
- StockX suits new, boxed sneakers and sealed or graded cards that buyers search for by exact product and size. You set an ask, and StockX checks every item before it reaches the buyer.
- Whatnot suits sellers who can run live shows, and it takes used, raw and one-off items that StockX will not list.
- StockX’s main marketplace charges a 9% to 7% transaction fee plus 3% processing, with a £4.50 or $5 minimum. Whatnot’s base US commission is 8% of the item price, and it drops as your four-week sales grow.
- FLUF sees Whatnot sales and ends the StockX ask. StockX sales you mark sold in FLUF, and it ends the Whatnot listing.
Which items belong where
The quickest test is condition. StockX’s main Verified Marketplace sells items in new, unworn condition with no signs of wear, with original packaging where it applies. Whatnot has no such rule, so worn trainers, loose cards, mixed lots and vintage pieces all have a home there.
- Deadstock sneakers in a common size: StockX. Buyers search for that exact product and size, and a fair ask sells without you saying a word.
- Sealed booster boxes and graded slabs: either. StockX takes sealed boxes, packs, and singles graded by PSA or BGS, as well as ungraded singles in sleeves and protective cases. A sealed box must be in its original shrink wrap without tears.
- Raw cards, bundles and mystery packs: Whatnot. Breaks and quick-fire auctions are what its buyers tune in for.
- Worn, customised or boxless pairs: Whatnot, where you can show the wear on camera.
How selling works on each
On StockX you do not write listings or talk to buyers. You pick a product that is already in StockX’s catalogue, choose the size and set an ask. When a buyer meets your price, you ship to StockX, which checks the item before sending it on. That suits a seller with stacks of identical boxes and little time. The only lever you have is price.
Whatnot is the opposite. You host a live show, talk through each item and let buyers bid against each other, or run fixed-price and timed listings between shows. A good host can push prices past what the same card fetches on a static listing. It also takes hours on camera every week, and a quiet night sells little.
StockX is testing live selling too. StockX Live is open to select sellers with a waitlist for everyone else, and at launch it charges sellers no selling or processing fees. Unless you already have access, compare Whatnot with StockX’s standard marketplace.
What each takes from a sale
On StockX’s Verified Marketplace, you pay a 3% payment processing fee plus a transaction fee set by your Seller Level. New sellers start at Level 1 on 9%, and the rate falls to 7% at Level 5, which needs 800 sales and $100,000 a quarter. Every sale also carries a minimum seller fee: £4.50 in Great Britain, $5 in the US and €5 in the EU.
Whatnot changed its commission in September 2026. According to Whatnot’s announcement, the base US rate is 8%, charged only on the item price, not on shipping or tax. Your sales over the previous four weeks set your tier for the next four, the first lower tier starts at $15,000 in four weeks, and rates go as low as 3%. Payment processing is charged on top. UK rates are set separately, so check the seller fees article for your country.
The minimum fee changes the sums for cheap items. A £20 graded card on StockX at Level 1 would owe £1.80 at 9%, but the £4.50 minimum applies instead, plus 60p processing. On a £300 pair of trainers the minimum does not matter, and the percentages decide it.
Selling the same stock on both
Plenty of sneaker and card sellers run both: StockX as the always-on shop window, Whatnot for the shows. The risk is selling one item twice, because a pair can sell on StockX while it is queued for tonight’s stream.
| StockX | Whatnot | |
|---|---|---|
| How you connect | Sign in with your StockX account | FLUF browser extension |
| FLUF sees a sale here | No, mark it sold in FLUF | Yes |
| FLUF ends the listing here when it sells elsewhere | Yes, it removes the ask | Yes |
| Relisting and offers | No | No |
In practice, a Whatnot sale takes care of itself: FLUF records it and removes the StockX ask. A StockX sale needs one click in FLUF, which then ends the Whatnot listing. Make that click as soon as StockX emails you, and before you go live.
Which to choose
Choose StockX if your stock is new, boxed, in StockX’s catalogue and you want to sell without being on camera. Choose Whatnot if you enjoy hosting, sell used or mixed items, or deal in cheap singles where StockX’s minimum fee eats the margin. If you have both kinds of stock, use both and let FLUF keep the two in step.
