Four Senate Democrats questioned whether Elon Musk’s platform X gives Polymarket preferential treatment in ad reporting, according to a joint letter reported by Semafor and cited by BlockBeats.
What the letter alleges
The senators said X’s standard reporting interface does not offer a reporting option for Polymarket ads, while users can report other ads, including Kalshi’s. They said the difference raises questions about an improper competitive advantage and potential benefits to President Donald Trump’s family. The letter’s claims are allegations, not an official finding. BlockBeats also noted that Donald Trump Jr. has invested in Polymarket and advises the platform.
