[US Democratic Lawmakers Accuse X of Giving Polymarket Special Treatment] Odaily reports that US Senate Democrats have accused X of giving special treatment to the prediction market platform Polymarket. In a letter, the lawmakers stated that users cannot select a reporting option when reporting Polymarket ads through X's standard interface, while this issue does not exist for other types of ads such as Kalshi. The letter also claims that this differential treatment could give Polymarket an unfair competitive advantage and mentions that Donald Trump Jr. is an investor and advisor to Polymarket. Neither X nor Polymarket responded to requests for comment.
