The prediction market platform will require traders in high-risk markets to disclose employment details to prevent insider activity.
Kalshi has implemented new market integrity measures, including mandatory employer disclosure for traders in markets flagged for elevated insider trading or manipulation risks. Affected traders must submit workplace details via an online form, though the company will not routinely verify submissions unless an inquiry is warranted. Certain employment, such as a Google employee trading on Google-related contracts, may disqualify participation in specific markets.
The platform also introduced a risk scoring framework evaluating markets across six dimensions, including corporate event risk, outcome concentration, and national security concerns. Markets scoring above a set threshold will trigger the employment verification requirement. Kalshi noted it avoids listing markets tied to war or violence but acknowledged some leadership and foreign policy markets may pose incidental risks.
The changes come amid growing scrutiny of insider trading on prediction market platforms, though Kalshi did not specify immediate market reactions to the new rules.
