Republican Senator John Curtis and Democratic Senator Adam Schiff urged the CFTC to investigate Polymarket after a report that it paid influencers to make videos of fake bets.

A Wall Street Journal probe found Polymarket paid creators to post 1,100 videos with fake trades and nearly $1.9M in fabricated winnings on dummy websites.

A bipartisan pair of senators pressed regulators to scrutinize the prediction market’s deceptive marketing. An investigation has already been underway.
