Polymarket Staged $1.9M in Fake Bets Across Creator Videos, WSJ Investigation Finds

According to a Wall Street Journal investigation published on June 21, 2026, Polymarket staged approximately $1.9 million in fake bets across paid creator videos, with roughly 70% of reviewed content filmed on cloned versions of the exchange rather than the live site. The company's chief marketing officer routed more than $2.5 million to over 800 creators via a personal PayPal account, generating more than 140 million views across TikTok, YouTube, and Instagram.

The revelation compounds existing integrity concerns: a Columbia University study estimated approximately 25% of Polymarket's historical trading volume through October 2025 exhibited characteristics of wash trading. The timing pressures the platform as it completes a $2 billion investment from Intercontinental Exchange (ICE) backing its CFTC-regulated U.S. relaunch.
