National Consumer Group Sues Polymarket Over Undisclosed Influencer Endorsements

The intersection of the creator economy and financial regulation is facing a high-stakes stress test. In late June 2026, the National Association of Consumer Advocates (NACA) filed a lawsuit in the Superior Court of the District of Columbia against prediction market platform Polymarket, its CEO Shayne Coplan, and its Chief Marketing Officer Matthew Modabber. The suit alleges a sweeping, multi-layered deceptive marketing campaign designed to lure young Americans into event-based trading.[1]

Rather than focusing on the legality of prediction markets themselves, the lawsuit zeroes in on the mechanics of modern stealth marketing. Consumer advocates claim the platform systematically paid political commentators, lifestyle influencers, and college students to promote the service without disclosing their financial relationships. This alleged strategy bypassed the natural skepticism viewers typically apply to traditional advertisements, presenting paid endorsements as organic, independent enthusiasm.[2]

The most complex mechanism detailed in the complaint involves the use of "simulated platforms." According to the filings and investigative reports, the company allegedly directed content creators to use clone websites—such as domains replacing the letter 'l' with an 'i'—to record their promotional videos. These simulated environments allowed influencers to place fabricated bets and record guaranteed "winning" trades without risking actual capital.[1][3]

By broadcasting these fabricated wins, the campaign allegedly created a false impression of the platform's profitability and ease of use. The Wall Street Journal previously reviewed over 1,100 such videos produced primarily by college-aged creators. The lawsuit argues that this tactic was specifically engineered to target younger demographics, leveraging the parasocial trust viewers place in their favorite creators to encourage real-money trading.

To obscure the corporate origins of this campaign, the lawsuit alleges a highly unconventional payment routing system. Investigators claim that Polymarket's Chief Marketing Officer utilized a personal PayPal account—registered under an email address associated with a salad shop he had previously co-founded—to distribute the funds. Between January 2025 and February 2026, this account allegedly transferred more than $2.5 million to over 800 individuals.[2]

Of those funds, at least $350,000 flowed directly to content creators and political influencers. The lawsuit names several high-profile figures who allegedly received payments, including political activist Riley Gaines, who reportedly received at least $6,000, and commentator Brian Krassenstein, who allegedly received $9,300. According to the complaint, these individuals subsequently posted positive commentary about Polymarket's forecasting accuracy without including any sponsorship identifiers.[2]

These alleged practices strike at the heart of the Federal Trade Commission's (FTC) disclosure regulations. The FTC mandates that any "material connection" between an endorser and a brand must be disclosed clearly and conspicuously. If a creator is paid to post, receives free access, or is given a script, the audience must be informed. Former regulatory officials note that the alleged failure to label these posts as paid promotions constitutes a clear violation of consumer protection standards.[1]

Beyond direct influencer payments, the lawsuit details a sophisticated "clipping" scheme designed to manufacture virality. The company allegedly recruited a decentralized network of secondary users to cut short excerpts from the primary influencer videos and distribute them across fake or anonymous social media accounts. These "clippers" were reportedly paid $1 for every 1,000 views their posts generated.[1]

The clipping strategy included explicit instructions to make the content feel "natural and native to the platform." By flooding algorithms with seemingly organic clips from multiple unaffiliated accounts, the campaign allegedly created an artificial consensus, making Polymarket appear to be a viral, grassroots phenomenon rather than the subject of a coordinated, paid advertising push.[1]

The platform's alleged promotional reach also extended offline, directly into college campuses. The lawsuit claims Polymarket partnered with a campus marketing firm to run street-level campaigns at multiple universities. The company reportedly offered to pay fraternities $15 for every new user they signed up, provided $150 payments for the opportunity to present the platform at chapter meetings, and sponsored parties with branded merchandise.[1][3]

This aggressive marketing push occurred as Polymarket was attempting to re-establish its footprint in the United States. In 2022, the platform was forced to exit the U.S. market after reaching a settlement with the Commodity Futures Trading Commission (CFTC) over operating an unregistered binary options platform, which included a $1.4 million penalty. The company only recently began allowing U.S. users back onto its platform in late 2025.[2]

The controversy has now drawn bipartisan attention from Capitol Hill. Senators John Curtis (R-Utah) and Adam Schiff (D-Calif.) have formally requested that CFTC Chairman Michael Selig investigate the platform's marketing practices. In their joint letter, the lawmakers asked the agency to determine whether the simulated betting activity and undisclosed influencer campaigns violate federal law or CFTC regulations, signaling a potential tightening of oversight for prediction markets.

Polymarket has not commented directly on the specifics of the lawsuit, though a company representative stated that the business is committed to maintaining accurate, transparent markets and is reviewing its user communication strategies. The NACA lawsuit seeks an injunction to halt the deceptive practices, alongside equitable restitution and the disgorgement of profits generated through the campaign.[2]

Ultimately, the case serves as a critical explainer on the evolving architecture of digital influence. As brands move away from easily identifiable banner ads and television spots, they are increasingly relying on decentralized networks of micro-influencers, simulated content, and algorithmic manipulation. For regulators and consumers alike, the Polymarket lawsuit underscores the growing difficulty of distinguishing genuine public sentiment from engineered, undisclosed marketing.[1]
