Democrats accuse X of blocking reports on Polymarket ads

The senators’ letter includes screenshots & says the gap could benefit President Trump & his family.

The hit

Four Democratic senators say X’s reporting tool won’t let users flag Polymarket’s adverts, according to a joint letter first disclosed by Semafor. The senators say the same reporting option works fine for other advertisers, including rival Kalshi. They allege the gap in treatment could be designed to benefit Polymarket.

Why it matters

If X is treating one prediction market’s ads differently to a rival’s, that’s a platform-policy question traders & operators may watch closely. The letter also ties the issue to the Trump family, adding political weight to what started as a tech complaint.

The record

Letter authors	Senators Cortez Masto, Rosen, Schiff & Blumenthal
Letter disclosed	First disclosed by Semafor
Trump family link cited	Letter alleges the gap could benefit President Trump & his family; Donald Trump Jr. has invested in Polymarket & serves as an adviser, per BlockBeats

What happens next

Watch for X’s response to the senators’ letter & whether the reporting tool is changed or explained. Any reply from Polymarket or Kalshi on the allegations would also shape the story.
