Traders on the event-contract platform Kalshi must now tell the company who they work for before placing trades in markets flagged as vulnerable to insider trading or manipulation. The new rule applies to a subset of contracts the platform considers high-risk.
What the rule demands
Under the updated policy, any user looking to trade in one of these designated markets will have to provide their current employer. The information must be submitted before the trade is executed. Kalshi has not said which specific markets are affected, but the rule targets contracts where a trader's employment could give them access to non-public information that might move the market.
Why the change
The move is meant to curb insider trading and market manipulation. By requiring employer disclosure, Kalshi gains a clearer picture of who is trading and whether they might have a conflict of interest. A trader who works for a company tied to an event contract's outcome — say, a firm whose earnings report is being bet on — would have to reveal that tie. The platform can then decide whether to restrict the trade or flag it for review.
How traders are affected
For most users, the change will mean an extra step when entering certain trades. Those who decline to disclose their employer will not be allowed to trade in the flagged markets. The rule does not apply to all contracts on Kalshi; only those the platform has identified as carrying a higher risk of abuse. Regular traders who do not work in industries related to the contracts they trade are unlikely to see much disruption.
The requirement is part of a broader push by Kalshi to build trust in its marketplace. Event contracts have grown in popularity, and with that growth comes scrutiny over fairness and integrity. Requiring disclosure is one way to show that the platform takes those concerns seriously.
