Politico reported in June that Polymarket's own chief marketing officer, Matthew Modabber, routed more than two and a half million dollars to over 800 people through a personal payment account between January 2025 and February 2026. At least $350,000 of that went directly to about two dozen influencers who then posted about Polymarket's odds on X without disclosing they had been paid. Those posts read like genuine enthusiasm from people who happened to like prediction markets. They were a coordinated marketing campaign running through someone's personal account. A published methodology that lists its own criteria, showing what decides a casino's rating by weighting licensing, payout speed, complaint history and support response times, works the other way: anyone can check it, disagree with it, and judge whether it holds up. No reporter required.
Gaming Has Been Here Before
In 2017 the Federal Trade Commission brought its first case against individual social media influencers, and the target was a gambling site built for the gaming community. Trevor Martin and Thomas Cassell ran CSGO Lotto, a skin gambling platform built on Counter-Strike items, and promoted it to their own audiences as regular users without mentioning they owned the company. Both men had large gaming audiences who had no idea the enthusiastic recommendations they were watching were coming from the platform's founders.
The FTC settlement required no payment from either man. The disclosure rules it forced on them going forward were the entire point: an endorsement that hides who is paying whom is not an endorsement, it is an ad in disguise. That principle applies whether the product is a Counter-Strike gambling site or a prediction market, and whether the audience is a Twitch community or a feed of X users following odds content.
Undisclosed Paid Promotion Is a Recurring Pattern, Not a One-Off
Both cases share a core problem. An audience sees what looks like a genuine recommendation with no way to verify whether the person making it has a financial relationship with the product. In late June 2026, the National Association of Consumer Advocates sued Polymarket, its CEO Shayne Coplan, and Modabber directly in a Washington D.C. court, accusing the company of deceptive marketing aimed at reaching American bettors on a platform not technically available to them. The suit drew on the undisclosed posts Politico first surfaced.
Nine years separate the CSGO Lotto case from Polymarket, which suggests this is not a problem platforms solve so much as one that keeps reappearing in new forms each time a payment method makes concealment easier. The broader shift in how games and platforms handle monetisation and disclosure is exactly where this audience already pays close attention. That scrutiny players apply to in-game purchase transparency applies equally when a platform is paying influencers to look like organic fans.
A Published Method Can Be Checked, a Personal Account Cannot
There was no way for anyone outside Polymarket to verify a payment moving through a personal account rather than a documented sponsorship arrangement. The relationship stayed hidden by design, which is why investigative reporting was required to surface it at all.
A published rating methodology works differently. Weighted criteria are visible before a reader decides whether to trust a score. Licensing status, payout speed, customer support response times, and game range each contribute a defined share of the final result. A reader can disagree with the weighting, query the methodology, or check whether their own experience of a platform matches what the rating claims. A visible bias that can be challenged is a different problem from an invisible one a reader has no way to detect.
Most Paid Gambling Promotion Still Goes Undisclosed
Industry tracking on creator disclosure across gambling-adjacent platforms puts current compliance in the low single digits. The Poynter Institute, which studies the gap between what audiences assume they are seeing and what is happening behind a recommendation, has documented the erosion of trust across influencer marketing broadly, not only in gambling. Not every creator talking about a casino platform is hiding something, and most disclosure failures come down to platforms not enforcing their own rules rather than deliberate concealment on Polymarket's scale.
But when the two clearest examples of undisclosed paid influence in this space both became national news stories, a published methodology a reader can examine is worth considerably more than a name they are asked to trust. The two cases also show how concealment gets harder to detect over time. CSGO Lotto hid behind ordinary gaming content uploads. Polymarket hid behind a personal payment account moving money that never touched a corporate ledger anyone could subpoena easily. Each new format gives undisclosed promotion one more place to hide, which is exactly why a fixed, published set of criteria for evaluating a platform matters more than trusting whichever format looks most convincing this year.
