Kalshi plans to make users disclose their employer before trading in certain prediction markets, a new rule targeting insider trading risks around political outcomes, corporate events, and policy decisions. The policy, expected within weeks per the Wall Street Journal, comes after the White House warned staff against using non-public government information on platforms including Kalshi and as House Oversight Committee Chair James Comer probes user verification practices.
Why the rule is coming now
The White House internal email on March 24, 2026, told staff not to use non-public government intel on prediction markets. Then in May, Comer sent letters to Kalshi CEO Tarek Mansour and Polymarket's counterpart asking about suspicious activity monitoring. The timing isn't coincidental. Kalshi already opened over 200 insider trading investigations in the year leading to February 2026, resulting in fines and multi-year suspensions — including for a MrBeast video editor who traded on upcoming content and multiple congressional candidates who bet on their own races.
What the new requirement covers
The employer disclosure will apply to markets with "elevated MNPI risk" — material non-public information risk. That includes contracts tied to political outcomes, corporate events, and policy decisions. Users will have to fill out an online form with their employer's name. Kalshi already runs detailed onboarding for high-risk individuals and real-time trade surveillance with third-party partners. The new rule adds a layer meant to catch people who might trade on inside knowledge from their job.
How Kalshi enforces compliance
Kalshi operates as a CFTC-regulated exchange with mandatory KYC and fiat infrastructure — a different setup from less-regulated crypto-native rivals. Its existing toolkit includes account freezes during probes, referrals to the CFTC and DOJ, and disciplinary actions ranging from fines to suspensions. The employer disclosure is supposed to make it harder for someone to hide a conflict of interest. But the exchange hasn't said how it will verify employer data or whether the form will be checked against trade surveillance alerts.
What happens next
Kalshi is expected to finalize the employer disclosure policy within weeks. The exact rollout date and verification methods remain unclear. The House Oversight probe is still open, and the White House hasn't issued further guidance. Prediction markets are growing fast, and insider trading questions aren't going away. Kalshi's next move will be watched closely — both by regulators and by users who don't want to fill out another form.
