Polymarket Paid Influencers to Stage Fake Bets on Copycat Sites, WSJ Investigation Finds

A Platform Built on Transparency. A Marketing Campaign Built on Its Opposite.

Polymarket has spent years positioning itself as something different from a sportsbook or a casino. Its core pitch is radical transparency: every trade settled on the Polygon blockchain in USDC, every position publicly verifiable, every outcome resolved through a permissionless oracle that anyone can dispute. You can see exactly what the market believes, because every bet is on-chain.

A Wall Street Journal investigation published June 21, 2026, found that some of Polymarket's most-watched marketing content was built on the inverse of that promise.

The Journal reviewed 1,105 videos from 10 creators posted between December 2025 and mid-May 2026. In about 778 of them, someone appeared to be placing a bet on Polymarket. According to the investigation, not one of those bets was placed on the actual Polymarket exchange. Instead, creators filmed themselves on near-perfect copycat versions of the website that Polymarket had built specifically for the campaign—lookalike domains designed to mimic the real platform while producing results the real market would never have generated.

How the Scheme Worked

The mechanics were straightforward. Polymarket, working with a marketing contractor, built near-identical replicas of its platform on domains engineered to look authentic. One reportedly ran at the address poiymarket.com—indistinguishable from polymarket.com when the letter "i" is rendered in capitals.

Creators were paid $2,000 to $3,000 a month to film themselves placing and winning bets on these dummy sites. They were instructed not to disclose the payments. Some added a @polymarket partner note to their bios only after Journal reporters began asking questions.

A marketing firm called Virality managed the creator network and, per the Journal's account, paid creators only when at least 60 percent of their audience was based in the United States.

That American focus is where the story turns legally uncomfortable.

Polymarket's main crypto-based exchange has been closed to US users since a 2022 settlement with the Commodity Futures Trading Commission, which carried a $1.4 million penalty. The platform agreed to stop offering its unregistered prediction market services to Americans. A steady stream of staged jackpots—targeting US audiences who cannot legally place the bets being shown—became a marketing engine for a product those viewers could not access without a VPN.

Across 118 videos, creators celebrated nearly $900,000 in fabricated wins. The Journal found that the same wagers, placed on the real Polymarket exchange, would have lost more than $166,000. In one case, a college-age creator filmed himself collecting a $100,000 payout on a market asking whether Donald Trump would say the word "McDonald's" in a speech. The footage was roughly two months old. Public on-chain records showed that every real account that placed the same bet lost.

The Scale of the Campaign

The videos collectively drew more than 140 million views across TikTok, YouTube, and Instagram, according to the analytics firm Tubular. Virality also deployed a network of human commenters to amplify the content and make it appear organic. Some were reportedly told to remove any reference to the Polymarket brand from their usernames to make posts look more personal and authentic.

The campaign extended to insider-trading adjacent content: at least 19 videos pushed guidance on how to trade on inside information—an uncomfortable look for a platform that explicitly prohibits trading on confidential data and is under ongoing scrutiny by US regulators who are using AI tools to flag suspicious activity.

After the Journal contacted creators and Polymarket, many of the videos were removed. The copycat websites, including poiymarket.com, were taken offline.

"Polymarket is committed to maintaining accurate, fair, and transparent markets," the company said in a statement, adding that it plans to conduct a comprehensive audit of its promotional content.

TikTok and YouTube moved to restrict accounts linked to the network over disclosure violations.

The Second Marketing Scandal in Three Weeks

The WSJ investigation is not the first marketing controversy to hit Polymarket this month.

On June 5, Politico reported that Polymarket's chief marketing officer, Matthew Modabber, had used a personal PayPal account to compensate creators who promoted the platform's odds on X without labeling the posts as paid advertisements. That account reportedly sent more than $2.5 million to more than 800 individuals.

Taken together, the two reports describe a marketing operation that operated largely outside standard disclosure frameworks—while the parent platform was simultaneously pursuing mainstream legitimacy, a return to the US market through its federally regulated US entity QCX LLC (which received an Amended Order of Designation from the CFTC in November 2025), and reported IPO discussions.

What's at Stake

Prediction markets run on a specific kind of trust. They ask users to believe that prices reflect real expectations, real money, and real risk. The informational value of a 63% probability only means something if the 63% comes from traders with skin in the game. Manufactured virality that isn't—fake bets, staged wins, amplified by a coordinated network of commenters—does not just mislead new users. It undermines the epistemic premise that makes a prediction market worth using.

Polymarket's offshore exchange is not the only part of the industry under pressure. At the state level, 18-plus states have initiated legal proceedings against prediction markets, the Kentucky Attorney General filed lawsuits against both Kalshi and Polymarket on June 17 in Franklin Circuit Court, and Minnesota enacted a law in May making operating a prediction market a felony (which the Trump administration sued to block before its August 1 effective date). Federal regulators are already watching the sector closely.

A marketing campaign built on fake trades, undisclosed payments, and lookalike domains does not help platforms arguing they are legitimate financial exchanges subject to exclusive federal oversight—not gambling operators subject to state gaming laws.

Polymarket's blockchain records what actually happened. The marketing showed something else.
