On June 16, 2026, Gymshark USA, Inc. became the latest brand to face a proposed class action challenging how companies use social media influencers to promote consumer products. Filed in the U.S. District Court for the Southern District of New York, Lupea v. Gymshark USA, Inc., No. 1:26-cv-05073, alleges that Gymshark built part of its marketing strategy around paid influencers whose endorsements appeared to consumers as independent recommendations rather than advertisements.
The lawsuit reflects a growing shift in consumer litigation. Plaintiffs are no longer focusing solely on whether a particular influencer failed to include “#ad” or another disclosure. Instead, they are asking courts to examine whether a company’s entire influencer marketing program creates a misleading impression for consumers. For brands that rely heavily on creators, ambassadors, and affiliate partnerships, the case illustrates how advertising practices can become the basis for consumer protection claims even when the products themselves are not alleged to be defective.
Consumer Class Action Targets Gymshark’s Influencer Marketing Program
According to the complaint, Gymshark entered into sponsorship agreements with influencers who promoted its apparel across social media platforms. The plaintiff alleges that these relationships were not always presented to consumers in a clear and obvious way, creating the impression that endorsements reflected genuine personal opinions rather than paid advertising.
The complaint also alleges that Gymshark maintained long-term relationships with influencers, including agreements that limited their ability to promote competing athletic apparel brands. The plaintiff argues that this level of coordination makes the alleged disclosure issues part of a broader advertising strategy rather than isolated mistakes by individual creators.
Gymshark has not been found liable, and the allegations remain unproven. The litigation is in its early stages, and the company will have an opportunity to respond to the claims through the court process.
The lawsuit does not allege that Gymshark’s products failed to perform as advertised. Instead, it claims that consumers paid more for the products because they believed influencer endorsements reflected independent recommendations. This theory, commonly referred to as a “price premium” claim, has become increasingly common in consumer class actions involving product labeling, environmental claims, and advertising practices.
FTC Endorsement Guides Continue to Drive Influencer Marketing Lawsuits
One of the more interesting aspects of the lawsuit is that it does not seek relief under the Federal Trade Commission Act itself. Consumers generally cannot bring private lawsuits under the FTC Act. Instead, the plaintiff relies primarily on New York General Business Law Section 349, which prohibits deceptive business practices.
The FTC’s Endorsement Guides nevertheless play a central role because they establish widely recognized expectations for influencer advertising. Under those guides, any material connection between a company and an influencer should be disclosed in a manner that is clear, noticeable, and understandable to consumers. Hidden disclosures, vague language, or disclosures that appear only after a consumer must expand a post may create advertising exposure.
This approach has become increasingly common in recent litigation. Similar lawsuits have been filed against brands including ALO Yoga, Revolve, Celsius, Shein, and Beach Bunny. While several of those cases remain pending or have produced procedural rulings rather than final decisions, they demonstrate a broader effort to use state consumer protection statutes to challenge influencer marketing practices.
For many companies, the legal question has evolved beyond whether an individual influencer properly disclosed a sponsorship. Courts are increasingly being asked to examine how brands design, supervise, and monitor entire creator marketing programs.
Influencer Oversight Could Define the Next Wave of Advertising Litigation
The most overlooked issue in the Gymshark lawsuit is not disclosure language itself. Instead, it is the plaintiff’s focus on the company’s alleged control over influencer relationships.
According to the complaint, Gymshark maintained ongoing contractual relationships with influencers and imposed restrictions regarding competing brands. Those allegations may encourage courts to examine whether companies exercising greater control over creators also assume greater responsibility for ensuring advertising disclosures comply with consumer protection standards.
That distinction could affect how brands manage influencer campaigns moving forward. Companies may increasingly be expected to document internal review procedures, monitor sponsored content after publication, retain records demonstrating disclosure requirements were communicated, and establish processes for correcting posts that fail to meet advertising standards.
For businesses operating in consumer products, apparel, food and beverage, cosmetics, supplements, and wellness industries, this represents a broader product representation risk. Marketing departments often focus on campaign performance, while legal teams focus on advertising review before publication. The Gymshark litigation suggests that courts may also examine what happens after content goes live and whether brands actively supervise ongoing influencer relationships.
strategic by design: The Juris Law Group Perspective on Advertising Law
Influencer advertising has become an established part of modern brand development, but it also creates a growing area of advertising liability. As brand protection attorneys, our work frequently involves evaluating marketing programs as complete systems rather than reviewing isolated advertisements. Contracts, approval procedures, disclosure language, internal training, and recordkeeping all influence how a campaign may be viewed if challenged in court.
The Gymshark case also highlights a legal gap that many companies overlook. FTC guidance explains when disclosures should be made, but consumer class actions increasingly focus on whether a company’s internal oversight was sufficient to prevent misleading advertising in the first place. That question reaches beyond social media captions and into governance, contract management, and documentation. As we often remind clients, Bigger is not better, better is better®. Well-designed advertising practices generally provide stronger protection than simply expanding a creator network without consistent oversight.
How the Gymshark Case Could Shape Future Advertising Litigation
Over the next twelve months, Gymshark will likely seek dismissal of the complaint or challenge whether the plaintiff can establish that consumers actually suffered an economic loss because of the alleged disclosure practices. The outcome will be closely watched because similar lawsuits are pending against several consumer brands, and courts have not yet established a consistent framework for evaluating these claims. Early rulings could influence how future plaintiffs plead influencer marketing cases under state consumer protection statutes.
More broadly, companies that rely on creators should expect greater scrutiny of their advertising programs regardless of the outcome of this case. Regulatory attention from the FTC continues alongside private class action litigation, creating two separate sources of enforcement risk. As influencer marketing becomes more sophisticated, businesses should expect courts to examine not only what consumers saw, but also how brands designed, supervised, and documented their marketing relationships behind the scenes.
Common Legal Inquiries
Can consumers sue a company directly for violating the FTC Endorsement Guides?
No. The FTC Act generally does not give consumers a private right to sue. Instead, plaintiffs often rely on state consumer protection laws, arguing that advertising practices inconsistent with FTC guidance also constitute deceptive business practices under state statutes.
Can a company be responsible for an influencer’s failure to disclose a sponsorship?
Potentially. While responsibility depends on the specific facts, courts increasingly examine the company’s role in selecting influencers, approving content, establishing disclosure requirements, and supervising ongoing marketing relationships. Strong oversight procedures may become increasingly important as these cases develop.
What should brands review to reduce influencer advertising exposure?
Brands should regularly evaluate influencer agreements, disclosure requirements, approval procedures, monitoring practices, training materials, and documentation showing that sponsored content is reviewed for advertising compliance. Consistent internal processes often provide stronger protection than addressing disclosure issues only after a complaint arises.
