Kalshi opened nearly 60 election-trading probes since January
Prediction market platform Kalshi has launched nearly 60 investigations into trading on elections since January, the company disclosed this week. About 40 to 45 of the probes are directly election-related. The investigations come as Kalshi and other prediction market platforms face scrutiny over potential market manipulation and insider trading ahead of the 2026 midterm elections. The disclosure follows senators demanding election-trading safeguards from Kalshi and Polymarket, and after Polymarket referred at least two of its own election cases to the CFTC.
Each investigation Kalshi discloses strengthens its hand in Washington but also invites closer inspection of what it missed. Senators Warren and Curtis have already demanded surveillance data from both platforms, and any gap between internal detection and public reporting feeds directly into congressional oversight tracks. The platform built its defense against state gambling suits on federal registration credibility, yet Ohio and Tennessee have already stripped that shield.
Every probe Kalshi publicizes becomes evidence state attorneys general can use to argue that self-policing is insufficient. A weak or delayed response to the Senate demands would hand those prosecutors a fresh talking point. The first platform to stumble under this dual pressure will set the transparency standard every competitor must fund.
Polymarket's own referrals to the CFTC undercut the credibility argument it uses against state gambling suits, joining Kalshi's disclosures in a pattern of platforms now forced to police themselves before regulators or courts do it for them.
