Reselling News: Whatnot Says Shill Bidding Is Down Nearly 80 Percent and eBay Closes on Depop July 30

Two stories this week land on the same nerve, which is trust. One platform is publishing numbers on how hard it is policing its own auctions, and another marketplace is about to change owners. Neither one asks you to log in and fix a listing today, but both change how a certain kind of seller should be operating.

Whatnot says it cut shill bidding by nearly 80 percent

Whatnot published an update on July 23 laying out what it has been doing about shill bidding, the practice of running up a lot with bids that were never meant to win. On the company blog, Whatnot says it cut shill bidding activity by nearly 80 percent over the past six months, increased the number of signals it uses to proactively detect it by 5x, and doubled the size of its Trust and Safety team with more data scientists, machine learning engineers, and investigators. Confirmed cases end in restricted or permanently banned accounts. Value Added Resource covered the update on July 28 alongside the wider legal scrutiny live shopping has been under.

Read that as a detection story, not a public relations story. The interesting part is the 5x on signals. Modern shill detection is not one person watching a stream and noticing a suspicious bidder. It is account relationships, device patterns, payment history, and how a given bidder behaves compared to a normal one. That means the informal stuff a lot of live sellers treat as harmless gets caught in the same net.

If you run live shows, the safe rule is simple. Nobody connected to you bids in your room. Not a second account of your own, not your partner, not the friend who watches every show and helps things along when a lot is quiet. If a lot is not getting bids at the price you need, the fix is a reserve or a starting price that reflects what the item is worth, not a bid you arranged. An account ban takes your whole sales channel with it, and there is no appeal that gives back the following you spent a year building.

eBay's purchase of Depop closes July 30

The Depop sale becomes official tomorrow. Etsy's 8-K filing sets closing for July 30, 2026, after the UK Competition and Markets Authority cleared the deal on July 15, and raises the business disruption fee to 158 million dollars if the agreement were terminated after that clearance date. eBay announced the acquisition in February at roughly 1.2 billion dollars in cash, and has said Depop keeps its name, brand, and platform after the deal.

For anyone selling on Depop, nothing changes on Friday. Ownership changes have a long tail, and the parts that actually reach sellers are fees, payout processing, and category policy. Those tend to move quarters later, not days later. What is worth doing now is small: export or screenshot your Depop sales history so your own numbers do not live only inside someone else's dashboard, and start paying attention to eBay's seller announcements even if eBay is not currently one of your channels. The company that just bought your marketplace tells you how it thinks about fees in public, every quarter.

The broader read is that a US buyer now owns a platform whose core audience is young and fashion first. If your inventory skews vintage, streetwear, or Y2K, this is a channel that just got a much deeper pocket behind it.

The takeaway

Both items reward the same habit. Know the rules of the room you are selling in, and keep your own records so a platform decision is an inconvenience instead of a disaster. Building a business that survives a policy change, an ownership change, or a bad month is the whole point of the system we work through inside The Income Lab.
