Nike has filed a lawsuit against resale platform StockX, alleging the sale of counterfeit Nike sneakers and false advertising regarding their authentication process.

The lawsuit, initiated in February 2022, has evolved from concerns over non-fungible tokens (NFTs) to broader claims of trademark infringement and consumer deception. A federal judge ruled in March 2025 that StockX was liable for selling 37 counterfeit Nike sneakers, but dismissed other claims, including false advertising. The remaining issues are scheduled for trial between June 15 and November 15, 2025.

The ongoing legal battle between Nike, Inc. and StockX LLC has garnered significant attention within the legal and retail industries. Initiated in 2022, this lawsuit centers on allegations of counterfeit sales, false advertising, and trademark infringement. Nike contends that StockX sold counterfeit Nike sneakers while falsely advertising their authenticity, thereby violating the Lanham Act and other related statutes.

Background of the Lawsuit

In February 2022, Nike filed a lawsuit against StockX in the Southern District of New York, accusing the resale platform of infringing upon Nike’s trademarks through the sale of non-fungible tokens (NFTs) associated with Nike-branded products. Nike argued that StockX’s use of its trademarks on these NFTs misled consumers into believing that Nike had authorized or endorsed the digital assets. Subsequently, Nike amended its complaint to include allegations of counterfeit sales and false advertising, asserting that StockX sold counterfeit Nike sneakers while advertising them as “100% Verified Authentic” .

Key Allegations and Evidence

Nike’s amended complaint outlines several key allegations against StockX:

• Sale of Counterfeit Sneakers: Nike claims to have purchased counterfeit Nike sneakers from StockX, including four pairs that were sold directly to Nike investigators and 33 pairs sold to a customer named Roy Kim.(SoapCentral)
• False Advertising: Nike alleges that StockX’s advertising of its authentication process as “100% Verified Authentic” is misleading, given the sale of counterfeit products on the platform.(The Fashion Law)
• Trademark Infringement: Nike asserts that StockX’s use of its trademarks on NFTs and other digital assets without authorization constitutes trademark infringement and dilution .(Rebecca Tushnet)

Court’s Ruling on Summary Judgment

On March 4, 2025, Judge Valerie Caproni issued a partial summary judgment in favor of Nike, ruling that StockX was liable for selling 37 counterfeit Nike sneakers, including four to Nike and 33 to a customer named Roy Kim. However, the judge denied Nike’s claims of false advertising, trademark infringement, and other related allegations. The court scheduled a trial to address the remaining claims between June 15 and November 15, 2025 .

StockX’s Defense and Counterarguments

StockX has vehemently denied the allegations, asserting that the counterfeit products identified represent a minuscule percentage of the millions of items it reviews. The company emphasizes its commitment to preventing counterfeit sales and highlights its efforts to reject products that do not meet its verification standards. StockX also disputes the characterization of its advertising as misleading, arguing that its authentication process is robust and reliable .

Implications for the Resale Market

The outcome of this lawsuit could have significant implications for the online resale market, particularly platforms that facilitate the sale of branded goods. A ruling in favor of Nike may set a precedent for holding resale platforms accountable for the authenticity of the products sold on their platforms, potentially leading to stricter regulations and increased scrutiny of authentication processes. Conversely, a ruling in favor of StockX could affirm the legitimacy of resale platforms’ authentication practices and their use of digital assets like NFTs in commerce.

Conclusion

The Nike v. StockX lawsuit underscores the complexities of intellectual property law in the digital age, particularly concerning the intersection of physical goods, digital assets, and online marketplaces. As the case progresses toward trial, stakeholders within the retail and legal industries will be closely monitoring its developments, as the final ruling could significantly influence the future landscape of online resale platforms and their operations.
