Prediction-market platform Polymarket secretly paid dozens of social media creators to record videos of themselves placing and winning bets that never happened, according to a Wall Street Journal investigation published Saturday. The company built near-perfect replica websites, had creators simulate trades on those dummy sites, and instructed them to conceal that Polymarket was behind the campaign — all in an effort to drive new users to its unregulated platform.
What the Scheme Looked Like
The mechanics mattered as much as the deception. Polymarket did not simply pay influencers to say nice things about the platform. Instead, it constructed convincing copies of its own website, then choreographed trades on those fakes so that the resulting videos would appear, at first glance, to show real money moving. The goal, the Journal reported, was to make prospective users believe ordinary people routinely strike it rich on the platform.
One creator, college student George Makihara, posted a video in January showing himself winning $100,000 on a bet that President Trump would publicly say the word "McDonald's" that month. Trade data reviewed by the Journal showed that no one on Polymarket actually won a bet like that in January. In total, Makihara appeared in content tied to 145 bets placed between January and May — every one of them simulated.
Why This Is a Commercial Problem, Not Just a PR One
Prediction markets sell a specific proposition: that prices reflect genuine collective belief about real-world outcomes, making them useful forecasting tools. That value proposition collapses the moment the platform's own marketing is built on fabricated outcomes. Advertisers, data buyers, and the users who bet real money all rely on the assumption that what they see on the platform reflects actual activity.
Polymarket operates without U.S. regulatory oversight, a detail the Journal flagged directly. That status makes the reputational stakes higher, not lower. Without a regulator setting baseline disclosure standards, the platform's credibility rests almost entirely on user trust — precisely the asset this campaign spent down.
The creators, meanwhile, were instructed to hide their paid relationship with Polymarket, raising questions about compliance with Federal Trade Commission endorsement guidelines that require paid promotions to be disclosed.
What Comes Next
The Journal's investigation does not detail what, if any, action regulators or platform partners are considering. But the exposure arrives at a moment when prediction markets have been seeking mainstream legitimacy, pointing to their forecasting accuracy as evidence they deserve a seat alongside traditional financial data sources. A documented campaign of fake-win videos undercuts that argument in the clearest possible way: it shows the platform was willing to manufacture the appearance of winners rather than let genuine results speak for themselves.
How Polymarket responds — whether through policy changes, leadership statements, or creator disclosures — will determine whether this episode reads as a correctable misstep or a defining one.
