Kalshi will require some users to disclose their employers before trading on certain prediction markets, the first major compliance overhaul by a federally regulated platform after a string of insider trading scandals.
"By implementing these new integrity measures, we continue to lead the industry on the issue of market integrity among federally regulated prediction markets," said Robert DeNault, head of enforcement at Kalshi.
The company will assign risk scores to new markets based on factors including corporate performance metrics, product launches, outcome concentration, national security implications and manipulation potential. Markets scoring high will trigger mandatory employment disclosures before users can trade. Kalshi said the screening tools have already stopped at least 100 potential insider trades, and it has made at least 20 referrals to law enforcement or securities regulators.
The overhaul follows a series of scandals that threatened the legitimacy of prediction markets. Last week, federal regulators disclosed they are investigating whether former Congressman George Santos engaged in potential insider trading on Kalshi. In April, a US Army soldier was charged with using classified information to make a $400,000 profit on rival platform Polymarket by betting on the timing of US military operations in Venezuela.
The measures, effective immediately, stem from recommendations by an independent Surveillance Audit Committee that Kalshi established in February to oversee market integrity and enforcement. The committee's work produced a framework that also includes a whistleblower portal and new reporting tools allowing users to flag suspicious trading activity directly from market pages.
Kalshi said employment information collected from users will only be used if suspicious activity is detected on the relevant market. The company will also identify presumptive insiders — people who hold material, nonpublic information about a market's outcome — and screen them out before a trade is placed.
The compliance push comes as prediction markets have drawn global interest and investor capital while operating largely outside the intense regulatory scrutiny applied to public equity markets and traditional exchanges. Kalshi has sought to differentiate itself from Polymarket, whose primary operations fall outside US jurisdiction.
The broader prediction market sector faces growing scrutiny from lawmakers concerned about market manipulation and insider trading. The new measures position Kalshi to argue it can operate with institutional-grade safeguards, potentially giving it an edge as regulators consider tighter oversight of the industry.
