Polymarket reportedly paid people to post fake videos of themselves placing bets

A Wall Street Journal investigation found that Polymarket allegedly paid creators to film deceptive clips showing themselves placing bets and celebrating wins without disclosing sponsorships. The report identified more than 1,100 such videos, with signs that some used lookalike domains rather than real betting activity.

The allegations highlight growing scrutiny of undisclosed influencer marketing in financial and prediction-market products. If regulators view the videos as deceptive promotions, platforms like Polymarket could face tougher enforcement and pressure to prove that viral user activity is authentic.
