Kalshi to roll out employer-disclosure rules after blocking 100 potential insider trades
Kalshi is rolling out measures to clamp down on insider trading, including plans to require some users to disclose their employers. The CFTC-regulated prediction market platform said it blocked more than 100 potential insider trades in the first quarter. CEO Mansour discussed the plans on CNBC's 'Money' on Tuesday. The moves signal tighter screening as Kalshi scales trading volume, though details of the full initiative remain limited. The announcement follows recent regulatory scrutiny of insider trading across prediction market platforms, including a DOJ case involving a Google engineer and Polymarket.
Kalshi's employment-verification system must now intercept informed traders before they profit. Any gap leaves the CFTC-regulated exchange exposed as a co-defendant when DOJ and CFTC file parallel insider-trading actions.
The clampdown follows the Google engineer Spagnuolo charged with $1.2M Polymarket insider trading using search data case, showing both major CFTC-regulated exchanges now face parallel pressure to self-report and surveil after DOJ brought criminal charges on a separate platform.
