Vintage and Resale Platforms: Who Is Liable for Fakes

The secondhand luxury market keeps growing, and so does the question nobody selling on it wants to answer directly: when a counterfeit slips through, who actually pays for it. The answer changes sharply depending on what kind of platform sold the item, and the difference comes down to one thing. Did the platform simply let a sale happen, or did it promise the buyer the item was real. Three cases across the last two decades draw that line clearly, and each one landed on a different side of it.

The Baseline: A Marketplace That Makes No Promises

Tiffany & Co. v. eBay, decided in 2008, set the standard every resale platform still operates under today. Tiffany sued eBay over third-party sellers offering counterfeit Tiffany jewelry, and the court ruled eBay was not liable, for two reasons that turned out to matter enormously later. eBay did not sell the goods itself, and it never claimed to authenticate anything sellers listed. A platform in that position only becomes liable for a specific counterfeit listing once it has actual, specific knowledge of that listing, not just a general awareness that counterfeits exist somewhere on the site. A pure peer-to-peer marketplace, one that never touches the item and never promises it checked anything, inherits almost none of the risk when a fake gets through.

Why Authentication Claims Flip the Risk Entirely

What Goes Around Comes Around learned the opposite lesson the hard way. A New York jury ruled against the reseller in February 2024 in Chanel, Inc. v. What Goes Around Comes Around, finding WGACA liable on all four of Chanel’s claims: trademark infringement, false association, unfair competition, and false advertising. The jury pointed to specific evidence, including thirteen handbags carrying voided, stolen Chanel serial numbers and fifty one more bags bearing other voided numbers, and found the infringement willful. Chanel walked away with $4 million in statutory damages, a permanent injunction, and over half a million dollars in litigation costs. WGACA’s defense leaned on its own authentication process, arguing it had no way of knowing the bags were not approved for resale. The jury did not buy it, and the case turned on exactly the promise eBay never made: WGACA told customers it verified authenticity, and that promise became the standard it got measured against.

The RealReal’s Version of the Same Fight Stays Unresolved

Chanel filed a nearly identical theory against The RealReal, alleging the platform’s marketing implied a level of Chanel approval and authentication accuracy it could not actually deliver. Unlike the WGACA case, this dispute has not produced a verdict. The litigation has run through years of motions, a stay, failed mediation, and a partial dismissal of RealReal’s own countersuit claims, without a court ever ruling on the merits of whether RealReal’s authentication claims crossed the same line WGACA’s did. The uncertainty itself tells resellers something. A platform that markets itself on the strength of its authentication, the way RealReal does, carries a live legal question hanging over it for years, in a way a platform that never made that promise simply does not.

Managed Marketplaces Built Their Whole Model Around This Risk

The resale industry has largely split into two structures because of exactly this exposure. Peer-to-peer marketplaces let individuals handle the entire listing and sale themselves, while managed marketplaces like The RealReal, Fashionphile and Vestiaire Collective take on authentication and often physical possession of the item before it reaches a buyer. That second model sells trust as the actual product, which is also why it absorbs more legal exposure the moment that trust turns out to be misplaced. The tradeoff runs in both directions, though. A managed marketplace can also point to real, documented process when a dispute arises, something a pure peer-to-peer site never builds in the first place. Vestiaire Collective runs dozens of physical and digital authenticators worldwide and reported intercepting close to $120 million worth of fakes in a single year, according to its own public reporting, and has not faced a Chanel-style lawsuit on the scale WGACA or RealReal did. Whether that reflects a stronger process, a different relationship with brands through its Official Partners program, or simply not yet triggering the same complaint, the legal question these platforms face never fully goes away just because a court has not tested it yet.

The Rule That Actually Emerges

Liability in resale tracks the specific promise a platform makes, not simply whether a fake ever reaches a customer. A marketplace that stays silent on authentication inherits the light-touch standard eBay enjoys. A platform that builds its entire brand on a guarantee of authenticity inherits WGACA’s exposure the moment that guarantee turns out wrong even once. The safest legal position in resale is not the platform with the best detection technology. It is the platform that promised the least and still delivered more than it promised.
