Kalshi Requires Employment Information Disclosure to Prevent Insider Trading

Prediction market platform Kalshi is introducing new rules to prevent insider trading. It will require users to disclose their employment information for certain bets. The Wall Street Journal first reported the story, which Engadget later covered.

The new rules are expected to be rolled out gradually within the coming weeks. Bets related to corporate performance and national security are likely to be targeted, though specific guidelines have not yet been published. A Kalshi spokesperson stated that for accounts where suspicious activity is detected, it will be standard practice to verify the user’s employment information.

A Series of Insider Trading Incidents

Insider trading in prediction markets has repeatedly been a problem. Kalshi itself has already seen several high-profile cases: an incident involving an employee of famous YouTuber “MrBeast,” trading allegations against three political candidates (one of whom touted fraud as a commitment to prediction market regulation), and most recently, an insider trading claim against former U.S. Representative George Santos.

These cases highlight the vulnerability of prediction markets to participants who possess inside information. Kalshi’s new rules are positioned as a concrete measure to address such risks.

Questions About Effectiveness

Whether the new rules can substantially curb insider trading remains unclear. Given the tendency of prediction market users to disregard rules in the past, some point out that new workarounds may simply emerge.

Disclosing employment information alone cannot prevent indirect insider trading through family members or acquaintances. Additionally, it is not clear how the verification process for disclosed information will actually function, and the specifics of Kalshi’s monitoring system remain undisclosed.

Complex Landscape of Regulation

The regulatory tug-of-war over prediction markets continues within the United States. Several states have filed lawsuits to classify prediction markets as gambling and regulate them accordingly. However, the federal government has intervened, asserting exclusive jurisdiction over this area through the Commodity Futures Trading Commission (CFTC), pushing back against state efforts.

Internationally, regulatory momentum is accelerating. Spain has already decided to ban prediction markets, and domestic authorities there are considering the future of regulation. In this context, Kalshi’s new rules can be seen as one measure within a broader trend toward strengthened governance across the industry.

Editorial Opinion

In the short term, Kalshi’s move is expected to help boost the platform’s credibility. In response to criticism over past misconduct, the company needed to show a commitment to greater transparency. However, requiring employment information as a tactic is a relatively easy level of countermeasure for serious insiders to bypass. If more sophisticated fraudulent methods are discovered within the next three to six months, this rule may prove ineffective.

From a long-term perspective, the regulatory framework for prediction markets itself is likely to change. As jurisdictional battles continue between the U.S. federal government and state governments, major platforms like Kalshi taking self-regulatory action may influence the formation of industry-wide standards. Meanwhile, the international trend toward stricter regulation could impose significant constraints on operations outside the U.S.

Our editorial view is that balancing the social utility of prediction markets with the risks of insider trading will become an increasingly important issue. If trading that exploits information asymmetries becomes routine, market trust will be eroded, and the core value—prediction accuracy through collective intelligence—will also be lost. It will be worth watching whether this new rule ends up as mere window-dressing or evolves into an industry standard.
