Election Day leaves senators awaiting public answers from Kalshi and Polymarket
Gaming America reports neither platform had published an answer on November 3 to the October 28 letter from Senators Warren and Curtis, which asked for counts of suspected insider trading and manipulation cases in election contracts identified, stopped before a trade, caught afterward and referred to the CFTC since January 1, 2026. Polymarket told the outlet it monitors election activity and refers suspicious traders to the Justice Department and the CFTC, while Kalshi did not respond to a request for comment by publication.
Kalshi and Polymarket had not published responses by November 3 to senators’ questions about suspected insider trading and manipulation in election contracts, according to Gaming America.
The absence of public answers on Election Day left the requested enforcement figures undisclosed. Gaming America’s report was published on Nov 3, 2026, at 6:00 PM ET.
Senators sought a breakdown of suspected cases
Senators Warren and Curtis sent the platforms a letter on October 28 seeking counts of suspected insider trading and manipulation cases since January 1, 2026.
Their request covered cases identified, those stopped before a trade, those detected afterward and those referred to the CFTC, according to Gaming America. That breakdown would distinguish intervention before trading from detection and referral after the fact.
Platforms’ responses differed
Polymarket told Gaming America that it monitors election activity and refers suspicious traders to the Justice Department and the CFTC. That statement described its monitoring and referral practices but did not provide the counts sought by the senators.
Kalshi did not respond to Gaming America’s request for comment by publication. The reporting establishes that neither platform had published an answer; it does not establish whether either had communicated privately with the senators.
What it means for prediction markets
- The requested figures would give readers a clearer view of how the platforms identify and handle suspected misconduct in election contracts.
- Polymarket’s statement provides an account of its practices, but not the numerical breakdown needed to assess the cases covered by the letter.
- The lack of published answers leaves an information gap. It does not, by itself, establish the presence or absence of insider trading or manipulation.
