Kalshi’s move is ruthless—by zeroing in on the insider trading’s weak spot, the employer disclosure goes straight for the jugular. The 2026 Q1 data looks really impressive, but the real question is whether execution can keep up.

Kalshi introduces mandatory employer disclosures to curb insider trading, reporting over 150 investigations, more than 100 blocked insider trading attempts, and 20 enforcement referrals in the first quarter of 2026. Risk scores are established for new markets, considering factors such as compliance, insider trading risk, market significance, and national security. For markets vulnerable to insider trading, employers must disclose before trading to identify potential insiders and restrict access prior to transactions.
