Two U.S. senators asked the Commodity Futures Trading Commission to investigate and provide written responses over allegations of deceptive marketing involving prediction market platform Polymarket.

Cointelegraph reported on Friday that Republican Senator John Curtis (존 커티스) and Democratic Senator Adam Schiff (애덤 시프) sent a letter to CFTC Chairman Mike Selig (마이크 셀리그), raising questions about Polymarket's advertising methods and the CFTC's regulatory enforcement capacity.

The senators cited reports that Polymarket paid social media influencers to film fake trading videos on sites made to look like its platform. They said if the allegations are true, it is highly concerning and warrants an immediate CFTC review.

The letter followed a Wall Street Journal report published on June 20. The Wall Street Journal reported that after reviewing more than 1,100 videos, about 70 percent contained fake bets totaling nearly $2 million. It also reported that many creators did not disclose they were paid by Polymarket.

Polymarket said earlier this week it is conducting a comprehensive audit of promotional content. It said the move is intended to check compliance with its standards, relevant regulations and legal disclosure requirements. Polymarket did not comment on the letter or reports of a CFTC investigation.
