What Is Whatnot?

Whatnot is a mobile-first livestreaming app where sellers open a live video broadcast, hold up cards one at a time, and either run a timed auction on each card or sell group-break spots before ripping packs live on camera. It is not a listing site you scroll — almost everything moves through a live stream, so buyers watch the product in the seller's hands and bid or buy in real time rather than reading a static description.

• Auction format— the seller shows a card, states a starting bid, and buyers tap to bid in a live comment feed. A countdown resets each time a new high bid lands until it expires, then the top bidder wins and gets invoiced automatically.
• Buy-it-now format— some items sell at a fixed price with no bidding, first buyer to tap wins the item.
• Live breaks— the seller sells spots (by team, player, or random draw) before opening a box on stream, the same core mechanic as a group break run elsewhere, just hosted natively inside Whatnot's app with built-in payment and spot tracking.
• Checkout— wins from a single show combine into one cart; the buyer pays once at the end rather than per item, and the seller ships everything together.

• Approval to sell— Whatnot vets new sellers before granting selling access (an application plus, in some categories, an initial trial show) rather than letting anyone list instantly.
• Category focus— trading cards is one of Whatnot's largest categories alongside collectibles, sneakers, and other verticals, with its own live-show schedule and seller community.
• Take rate— Whatnot charges a percentage commission on completed sales plus a payment-processing fee, deducted before seller payout. Confirm the current rate directly in Whatnot's seller terms, since platform take rates change over time.

1. Buyer Protection guarantee— Whatnot backs purchases made through the app with its own buyer-protection policy covering items that never arrive or arrive significantly not as described, similar in spirit to eBay's Authenticity Guarantee for what it protects against, though the mechanics and thresholds differ — check Whatnot's current policy before relying on it.
2. Live vs. browse-and-buy— eBay is primarily asynchronous: you browse listings and bid or buy on your own schedule. Whatnot is synchronous: you have to catch a show live (or its short replay window) to bid, which rewards sellers who build a scheduled, repeat audience.
3. Discovery— Whatnot surfaces shows by category and follows, closer to a streaming platform's feed than a search-driven marketplace, so a seller's following count matters more to visibility than it does on eBay.
4. Verify before you bid— the same rules apply as any online card purchase: check the seller's rating and show history, and treat an unusually low starting bid on a supposedly high-value card as a flag rather than a deal, the same way you would in a fixed-price listing.
