【U.S. senator accuses X of favoring Polymarket, questioning whether it is providing an improper competitive advantage】
Democratic U.S. senators accused Musk-owned social media platform X of giving preferential treatment to prediction market Polymarket. Nevada Democratic Senator Catherine Cortez Masto, California Democratic Senator Adam Schiff, Nevada Democratic Senator Jacky Rosen, and Connecticut Democratic Senator Richard Blumenthal wrote in a joint letter first disclosed by Semafor: Under normal circumstances,X allows users to report advertisements for various reasons. However, when users try to report X advertisements through Polymarket's standard interface, they are unable to select a reporting option. Other types of advertisements, including Kalshi's advertisements, do not have this problem. The letter, which included screenshots, alleged that this seemingly unfair special treatment raises questions about whether X is attempting to provide Polymarket with an improper competitive advantage, thereby benefiting the U.S. president and his family. Donald Trump Jr., the son of Donald Trump, has invested in Polymarket and serves as an adviser to the platform.

AI-assisted interpretation
The following is analysis, separate from reported facts. Verify important claims independently.
The senators believe that advertisement reporting functionality on X may not treat different prediction market platforms equally:Polymarket advertisements allegedly cannot be reported through the usual process, while Kalshi advertisements can. These are allegations and questions raised in the joint letter and do not mean that the alleged favoritism has been substantiated.
Why it matters to readers
The dispute concerns whether advertisement management on X is fair and whether Polymarket received special competitive treatment, and may also prompt scrutiny of potential conflicts of interest.
Beginners should distinguish between “senators raising questions” and “the facts having been established”: the existing materials can only confirm the allegations described in the joint letter and cannot establish that X actually favored Polymarket。
Risks and unknowns
The existing materials do not provide the complete original joint letter or the attached screenshots.
It cannot be confirmed whether X s advertisement-reporting interface differs in practice for Polymarket and Kalshi, or why.
The materials do not include a response from X、Polymarket or Kalshi.
It remains unclear whether a subsequent investigation or formal action will occur.
The letter's claim that the conduct would benefit the U.S. president and his family is an allegation, and the existing materials are insufficient to substantiate it.
