Prediction market platform Kalshi announced a sweeping set of compliance measures on June 10, 2026, introducing mandatory employer disclosures for traders in high-risk markets. The move comes as the sector faces mounting regulatory scrutiny, congressional probes, and criminal charges over insider trading.
The new rules require users to disclose their employer before trading on contracts deemed vulnerable to manipulation or insider abuse—such as those linked to corporate performance, national security, or major geopolitical events like the Iran war. The information is collected via an online form and remains unverified unless an investigation is triggered; however, the platform may restrict certain traders from individual contracts based on their employment.
Alongside the disclosure requirement, Kalshi launched a "risk scoring framework" that evaluates every proposed market on six factors—corporate KPI or events risk, outcome concentration, market importance, regulatory risk, non-traditional insider risk, and national security risk. Markets with high insider or manipulation risk may be rejected outright. The company also expanded whistleblower tools enabling users to report suspicious activity directly to its 24/7 surveillance team, and confirmed that its independent Surveillance Audit Committee will continue quarterly reports.
The announcement follows a series of enforcement actions. Kalshi disclosed it had opened over 150 investigations, blocked more than 100 potential insider trades, referred over 20 cases to law enforcement, and taken five disciplinary actions this year. Notably, the platform fined and suspended three political candidates for trading on their own elections—an act it labeled "political insider trading." Last week, Rep. Bryan Steil (R-WI) announced plans to extend a congressional stock ban to cover prediction markets, adding to legislative pressure.
The sector has been rocked by high-profile cases, including the DOJ and CFTC investigation of former Rep. George Santos over suspicious trading on Kalshi, the prosecution of a U.S. Army soldier for using classified information to trade on Polymarket, and charges against a Google engineer who allegedly made $1.2 million trading on confidential company data. Kalshi’s proactive steps may position it favorably as Congress weighs regulation of event-contract markets.
Meanwhile, Kalshi continues to expand its crypto-related offerings, having filed to self-certify contracts tied to major altcoins like Ethereum, XRP, Solana, and Dogecoin, as well as perpetual futures for Hyperliquid’s HYPE token. The platform surpassed $1 billion in perpetual futures volume within a week of launch, according to CNBC.
