The Non-Financial Ledger

This case is about trust that was engineered and then sold back to you at a markup. The complaint describes a generation of young people who followed fitness creators for encouragement, honesty, and community, and who were fed advertisements dressed up as friendship.

The named plaintiff, Mihaela Lupea, followed creators like Whitney Simmons and Annabel Lucinda because she believed their recommendations were genuine. The complaint states her purchase was driven by posts she took to be honest opinions from people she chose to trust. She did not understand these were compensated promotions.

The complaint describes Annabel Lucinda’s posts as “intimate confessions about her fitness journey, mental health, and her physical appearance,” monetized through undisclosed brand deals. The betrayal documented here is the conversion of personal vulnerability into a sales funnel aimed at “younger and comparatively impressionable demographics.” The harm is the quiet corruption of the one thing consumers thought was real.

Legal Receipts

The complaint speaks plainly about what Gymshark’s business model allegedly depends on. These passages are drawn verbatim from the filing.

“Gymshark is a popular athletic brand that has built a multi-billion dollar apparel empire on misleading social media marketing strategies that systemically masquerade paid influencer promotion as authentic endorsements of Gymshark products.”

• This is the core allegation: the deception is characterized as systemic, not accidental or the fault of a few rogue creators.
• It ties the company’s entire valuation to the alleged deception rather than to product quality.

“In one notable example, Gymshark sued one of its paid influencers for breaching its sponsorship agreement with Gymshark by promoting a different sportswear company even though, for years, that same influencer failed to adequately disclose that he was paid to endorse Gymshark products.”

• This documents that Gymshark actively enforced its contracts when a competitor benefited, proving the company monitored and controlled its influencers.
• It shows the company had the power to require disclosure and chose not to enforce it, while enforcing exclusivity.

“Gymshark employs the same misleading advertising tactics on other social media platforms like TikTok and YouTube.”

• The alleged conduct is not limited to a single platform, indicating a cross-platform strategy.
• It supports the claim that the practice was a deliberate corporate approach rather than an artifact of one app’s rules.

“Instagram’s algorithm deprioritizes ads that are displayed as Paid Partnerships, resulting in less reach and ultimately less revenue for both Gymshark and the influencer. As a result, Gymshark and its influencers go to great lengths to cover up their paid partnership.”

• This alleges a direct financial motive to hide disclosures: labeled ads reach fewer people and earn less.
• It frames the missing disclosures as a profit-driven choice, not an oversight.

Public Deception: The Gap Between “Organic” and Paid

The complaint alleges a persistent gap between what consumers were shown and what was actually happening behind each post.

• Consumers were told, through captions like “I only wear Gymshark” and “Best leggings I’ve found,” that these were honest personal preferences; the complaint alleges the creators were paid and, in many cases, contractually barred from wearing competitors.
• Posts appeared as “organic” non-sponsored content; the complaint alleges they were paid advertisements missing “#ad,” “#sponsored,” or the “Paid Partnership” tag.
• Gymshark’s website claims a “Gymshark family” with “customers in over 200 countries”; the complaint notes in a footnote that the United Nations only recognizes 195 countries.
• Consumers perceived Gymshark’s popularity as genuine consumer sentiment and organic market demand; the complaint alleges that desirability was “materially driven by undisclosed paid endorsements.”

Profit-Maximization at All Costs

The complaint alleges that hiding disclosures was not a bug but a revenue strategy, cheaper and more effective than honest advertising.

• The complaint states it is “cheaper for Gymshark to pay influencers to post stories or posts endorsing Gymshark without disclosures than for Gymshark to purchase advertising space” reaching the same audience.
• Because Instagram deprioritizes labeled “Paid Partnership” ads, the complaint alleges Gymshark and its influencers “go to great lengths to cover up their paid partnership” to preserve reach and revenue.
• Forbes reported in 2020 that Gymshark became “a $1.4 billion-plus” brand “by paying 80 ripped fitness influencers” between $6,000 to more than $100,000 per year to “live and sell the Gymshark lifestyle.”
• The complaint alleges Gymshark deliberately targets mid-tier influencers so their paid endorsements “appear comparatively authentic” and the practice is “more likely to fly under the radar.”
• Online estimates cited in the complaint place Gymshark’s 2024 revenue at over $800 million, with nearly half from the United States.

Legal Minimalism: The Letter but Not the Spirit

The complaint contrasts Gymshark’s conduct with a documented industry standard that competitors reportedly follow.

• The FTC Endorsement Guides under 16 C.F.R. § 255.5 require clear and conspicuous disclosure of any material connection; the complaint alleges Gymshark influencers routinely omit disclosures or bury them where they cannot comply.
• The FTC’s “Disclosures 101 for Social Media Influencers” (December 2019) states that burying disclosures “in hashtags, bios, or ‘more’ links does not comply”; the complaint alleges influencer Nell Grabowski’s disclosures require users “to click an additional button to see.”
• The complaint points to a 2024 National Advertising Division proceeding involving SKIMS, where SKIMS confirmed it requires paid influencers “by contract and through active monitoring” to disclose clearly; Gymshark is alleged to conduct endorsements “without the disclosures that the rest of the industry has accepted as the operative standard.”
• Nike, Lululemon, and Adidas are cited as competitors that “similarly require and obtain proper disclosures,” positioning Gymshark’s alleged omissions as a deviation from a settled norm.

The Contractor Shield: Deception by Proxy

The complaint alleges Gymshark structured its marketing so that hundreds of independent influencers, not the company itself, made the undisclosed claims, while Gymshark controlled and profited from them.

• Gymshark allegedly directs the content but pushes the legal exposure onto influencers who post the undisclosed ads, using “agent” influencers as the face of the deception.
• The complaint alleges Gymshark either “deliberately instructs or encourages its influencers to refrain from disclosing” or “deliberately fails to train, inform, and ensure that influencers abide by disclosure obligations.”
• Gymshark USA, Inc. is alleged to be a wholly owned subsidiary of Gymshark Limited of Solihull, United Kingdom; the parent company, not the US entity, was the plaintiff in the lawsuit against influencer Nathaniel Massiah.
• The complaint alleges Gymshark continued to extract “the price premium” and sales volume from this arrangement while the disclosure failures happened on the influencers’ individual accounts.

Manufactured Consent: Buying the Look of Authenticity

The complaint alleges Gymshark engineered a public image of grassroots community while paying for every piece of it.

• Gymshark markets its network as “Gymshark Athletes,” “ambassadors,” and a “Gymshark family,” language the complaint says is designed to portray paid agents as “genuine athletes” or “members of the community.”
• CEO Ben Francis is alleged to have “credited influencer marketing for the success of Gymshark’s multi-billion dollar valuation,” tying the strategy directly to the top of the company.
• The complaint alleges the company “cultivated an image of authenticity and community, especially with younger and comparatively impressionable demographics,” by disguising paid endorsements as personal recommendations.
• Gymshark opened Manhattan “popup” stores and a “flagship” store in late 2025 where it “hosted certain influencers,” extending the manufactured community into physical space.

Who Pays? Following the Cost

The complaint alleges the cost of this strategy was pushed directly onto consumers through inflated prices.

• Consumers absorbed a “price premium” the complaint says was “not bargained for,” paying more because undisclosed endorsements made products appear more desirable than honest advertising would have.
• The complaint alleges consumers were steered toward Gymshark over cheaper alternatives like YoungLA, Fabletics, CRZ, and Halara, which it says offer similar or better quality at lower prices.
• Cited academic research (He, Hollenbeck, Proserpio, and Reshef, NBER Working Paper No. 31836, 2023) estimates undisclosed promotions “reduce consumer welfare by approximately $0.12 for every $1.00 spent.”
• The complaint alleges consumers were also made “more likely to choose lower-quality products” as a direct result of the fake or undisclosed endorsements.

Societal Impact Mapping

Economic Inequality

The complaint frames the alleged deception as a transfer of wealth from ordinary buyers to a billion-dollar brand.

• Buyers paid a premium for Gymshark products that the complaint alleges are “of a similar quality, or are inferior to” cheaper competitors, meaning money flowed upward for no added value.
• The strategy is alleged to have helped drive over $800 million in 2024 revenue, nearly half from US consumers, much of it from the “younger and comparatively impressionable demographics” the complaint says were targeted.
• The complaint alleges Gymshark ranks among the “top 10 most common brands” promoted by influencers on Instagram and TikTok, “outranking giants like Walmart, Target, and Nike,” concentrating attention and dollars through undisclosed means.
• Honest competitors who followed FTC rules were allegedly disadvantaged, which the FTC describes as taking “business away from honest competitors that work hard to comply with the law.”

Public Health of the Information Ecosystem

The complaint documents harm to the trust that fitness and mental-health content depends on.

• Creators allegedly monetized “intimate confessions about their fitness journey, mental health, and physical appearance,” blending vulnerability with hidden sales pitches aimed at young audiences.
• Platform algorithms are alleged to “surface non-advertising-labeled posts more aggressively,” meaning the least transparent content reached the most people.
• The complaint alleges reasonable consumers were led “to believe that endorsements are the result of independent and unbiased opinions,” eroding the reliability of the recommendations people rely on to make choices.

The “Cost of a Life” Metric

This Is the System Working as Intended

The complaint describes a marketplace where hiding the truth is structurally more profitable than telling it.

• The complaint alleges Instagram’s algorithm “deprioritizes ads that are displayed as Paid Partnerships,” meaning the platform financially rewards non-disclosure, the exact opposite of what the FTC rules intend.
• FTC Endorsement Guides exist under 16 C.F.R. § 255.5, yet the complaint alleges Gymshark influencers “routinely flout federal guidance” with no documented enforcement action stopping them.
• The complaint alleges Gymshark could enforce contracts aggressively when a competitor benefited, suing influencer Nathaniel Massiah, but never enforced the far simpler requirement that those same influencers disclose they were paid.
• The result the complaint describes is a company that “silently captured wide swathes of the fitness influencer social media ecosystem” while operating below the threshold of household-name scrutiny.

What a Legitimate Fix Looks Like

Editorial analysis: this case exposes a system where disclosure rules exist on paper but carry no reliable consequence, and where platforms reward the deception. The following are our recommendations, not findings of the complaint.

Regulatory Track (editorial)

• The FTC should hold brands, not only individual influencers, directly liable when a documented pattern of missing disclosures traces back to a company’s contracts and marketing directives.
• Require brands running affiliate and ambassador programs to submit auditable proof of active disclosure monitoring, mirroring the contract-plus-monitoring standard the complaint attributes to SKIMS.
• Platforms should be pushed to stop algorithmically penalizing properly labeled “Paid Partnership” content, since that penalty is the documented incentive to hide disclosures.

Legislative Track (editorial)

• Codify the FTC Endorsement Guides into enforceable statute with meaningful per-post penalties, so disclosure is a legal duty rather than guidance that can be “routinely flouted.”
• Establish a private right of action, like the New York GBL § 349 claim in this complaint, at the federal level so consumers nationwide can seek redress for undisclosed advertising.
• Require public disclosure of exclusivity clauses in influencer contracts so audiences know a creator is contractually barred from endorsing competitors.

Corporate Governance Track (editorial)

• Mandate that any company built on influencer marketing designate accountable compliance officers whose role is to enforce disclosure, not just police exclusivity.
• Tie marketing-executive compensation to documented disclosure-compliance rates rather than reach and conversion alone.
• Require standardized, pre-approved disclosure language in every influencer contract, with the brand assuming liability for its enforcement.

What Now?

Direct your attention to Gymshark USA, Inc. (principal place of business, 38 Greene Street, New York, NY 10013) and its UK parent Gymshark Limited, along with the regulators empowered to act.

• Watch the FTC: it enforces the Endorsement Guides under 16 C.F.R. § 255.5 and the “Disclosures 101” guidance central to this complaint.
• Watch the SDNY docket: track Lupea v. Gymshark USA, Inc., No. 1:26-cv-05073, filed June 16, 2026, and any class certification ruling.
• Learn the tells: before you buy, check whether a post uses “#ad,” “#sponsored,” or the “Paid Partnership” tag, and treat “I only wear this brand” claims as marketing.
• Support honest disclosure: follow and amplify creators who clearly label paid content, and call out those who bury or omit it.
• Organize locally: share this case with peer groups and campus organizations frustrated with predatory marketing aimed at young consumers, and pool knowledge about cheaper, comparable alternatives.
