For decades, Walmart's role in this hobby was simple and fixed. It was where you checked the peg for a fresh case of blasters at 7 a.m., where you found a Funko two-pack nobody else stocked, where sealed product arrived from Topps and Panini and Upper Deck and then left in a shopping cart. Walmart was the primary market. Everything after that first purchase happened somewhere else, usually on eBay.
That arrangement is ending. Walmart has added a collectibles category to Walmart Marketplace, its platform for approved third-party sellers, and it is spending real money to fill it. The category covers trading cards, sports memorabilia, comic books, toys, coins, and media. Sellers apply, complete a collectibles survey, and get approved. In return they were offered zero percent referral fees from July 1 through September 30, with ongoing commission rates advertised as low as 4.8 percent, plus $2,000 in fulfillment service credits and $1,000 in search marketing credits.
The company brought that pitch to the 46th National Sports Collectors Convention outside Chicago this month with a bigger booth than last year and analysts from Mizuho walking the floor to size it up. The read on the show was that attendance ran roughly 20 percent above last year's six-figure crowd, and that Walmart's booth was one of the busier stops on it. That is not a company testing an idea. That is a company recruiting.
What Walmart is actually offering
The marketplace is still under construction, and it shows. Seller access remains invite-only while the platform builds out. Even in that limited state, individual transactions have cleared $30,000 for signed memorabilia, and Walmart collects a commission on each one.
The category structure is broad in a way that should interest collectors outside the sports card world. Eligible toys include figures, dolls, plush, trains, board games, LEGO, Funko, diecast, and Hot Wheels. Media and music covers movies, vinyl, instruments, and entertainment replicas. Comics and books have their own lane. Items can be listed new or pre-owned, cards and comics can be listed across a range of conditions, and support for graded listings is described as coming soon. Sellers also get variable return policies and the ability to run pre-orders, which matters more than it sounds for anyone who moves upcoming releases.
There is one gap worth naming directly. Nothing published so far spells out an authentication process or a specific anti-counterfeit program for the category. On a platform where a $30,000 autograph can change hands, that is the single most important detail still missing, and it is the one experienced sellers will ask about first.
Follow the fee math
Fees are why a story like this actually moves behavior. Run the numbers on a straightforward $400 raw card sale and the difference is not academic.
On eBay, trading cards carry a 13.25 percent final value fee for sellers without a store or on a Starter Store plan, calculated on the full order total including shipping and sales tax, plus a per-order fee of $0.30 or $0.40. There is a standing promotion that cuts that rate in half on singles at $1,000 and above, which is genuinely useful at the top end and irrelevant to most of what people actually sell. Whatnot charges roughly 8 percent plus payment processing of about 2.9 percent and $0.30, landing most sellers around 11 to 12 percent all in. COMC runs a consignment model with per-card intake fees, a transaction fee, and a cash-out charge that only pencils out at volume.
Against that, a 4.8 percent commission is a serious number, and a temporary 0 percent referral fee is an aggressive one. The obvious caveat is that fee rate is only half of the equation. The other half is what the item sells for. eBay's advantage has never been its pricing; it is that eBay is where collectors already look. A card that brings $400 on eBay and $310 on a platform nobody browses is a worse outcome at any fee rate. Live formats make the same point in reverse: Whatnot's auction energy regularly pushes hammer prices past what a fixed-price listing would have taken, which can erase a fee gap entirely.
So the honest way to evaluate Walmart's offer is not "cheaper fees, therefore better." It is "does walmart.com send buyer traffic to a listing for a 1998 insert." Right now, nobody knows. Walmart has more monthly visitors than any collectibles platform in existence, but general retail traffic and collector intent are different things, and converting one into the other is the hard part.
The hire that tells you how serious this is
Executives are a better signal than press releases. Walmart Marketplace brought on Bob Means earlier this year, who spent roughly seven years at eBay and served as its director of trading cards. He posted about the move on LinkedIn with a line worth reading twice: the home for your everyday needs will soon be the center of your everyday wants.
That is a positioning statement, not a job announcement. Hiring the person who ran cards at the platform that owns the secondary market is how a company signals it intends to compete there rather than dabble. It also means the playbook Walmart runs will be a familiar one, because it is being written by someone who helped build the incumbent's.
Walmart is not moving alone
Retail's push into collectibles is broader than one company. GameStop has spent the past two years converting itself into a collectibles business as much as a games business, and the numbers back the pivot: collectibles revenue climbed to $365 million from $270.6 million, roughly a third of total sales and up about 21 percent year over year. In April, GameStop launched Power Packs, a digital pack platform where buyers open packs to unlock real PSA-graded cards held in the PSA Vault, with the option to sell back instantly, ship home, or keep them stored. Packs run from $25 to $2,500. Select stores have also been buying PSA-graded cards outright for cash or credit, with restrictions on grade and value.
Meanwhile grading volume keeps climbing underneath all of it. Beckett reported card submissions up 102 percent year over year in July and paused parts of its operation to expand capacity. Mizuho pegs the U.S. trading card market somewhere between $10 billion and $20 billion, a range wide enough to admit how little anyone actually knows, but large enough to explain why national retailers keep showing up.
The Walmart-branded GradedGuard case is the small detail that captures the whole moment. It is a plastic protector for PSA slabs, produced in limited quantity, and it has already appeared on resale sites above $100. A retailer's giveaway became a collectible before the marketplace it was promoting is even fully open.
What to do about it
If you sell, treat this as a channel test and not a migration. Take the promotional period seriously, because free is free, but list items where the buyer pool is thinnest on other platforms rather than your best material. Sealed modern product, LEGO, Funko, and mid-priced raw cards are natural candidates. Keep your high-dollar consignments where the underbidders already are until Walmart shows it can produce competitive hammer prices. Track realized sale price, not fee percentage, and give it at least a full quarter of data before drawing conclusions.
If you buy, watch for the arbitrage window that opens whenever a new venue launches. Early marketplaces with thin traffic produce underpriced listings, and sellers chasing promotional fees often price to move. That advantage closes as the buyer base grows. Until authentication policy is published, be more careful with autographs and high-value graded material here than you would be on a platform with an established resolution process, and lean on third-party grading rather than seller descriptions.
Key Takeaways
- Walmart has opened its Marketplace to approved third-party collectibles sellers across cards, comics, memorabilia, toys, coins, and media, with graded listing support still in progress.
- The incentive package is unusually aggressive: a 0 percent referral fee window through September 30, ongoing commissions advertised as low as 4.8 percent, and $3,000 in combined fulfillment and marketing credits.
- Fee savings only matter if buyer traffic follows. eBay's 13.25 percent still buys the deepest pool of collector demand, and Whatnot's live format often produces prices that outrun its lower rate.
- Hiring eBay's former director of trading cards is the clearest indication Walmart intends to compete for the secondary market rather than experiment at its edges.
- GameStop's collectibles growth and the surge in grading submissions show this is a category-wide retail land grab, not a one-company story.
- No published authentication policy yet. Until there is one, use the platform where the risk is lowest and the upside from thin early competition is highest.
