PANews reported on June 10 that, according to the Wall Street Journal, Kalshi plans to require users participating in certain prediction markets to disclose their employer information to prevent insider trading and market manipulation. Users involved in sensitive markets such as company performance and national security (including the Iran war) will be required to submit an online form specifying their employer. Kalshi will not typically verify this information, only investigating and requesting proof of employment if suspicious activity is detected.

The report shows that in the first quarter of 2026, Kalshi filed more than 20 complaints with the CFTC and the Department of Justice, involving former Congressman George Santos and accounts associated with military spouses. Some of these accounts accurately placed bets days before the arrest of the former Venezuelan president, raising suspicions of using non-public information.
