New York, Illinois Move to Block State Employees From Insider Trading on Political Prediction Markets

New York and Illinois have moved to bar government employees from trading on prediction markets using insider information, responding to a regulatory gap that traditional securities law does not clearly address. The bans—issued through ethics guidance in New York and executive directive in Illinois—target state workers across the legislative, executive, and judicial branches who might exploit nonpublic policy knowledge for financial gain on platforms that allow wagering on political and regulatory outcomes.

The regulatory action follows a sharp surge in prediction market volume and visibility, with platforms like Kalshi gaining federal approval to list contracts tied to economic indicators and political events. As these markets have grown more liquid and politically salient, concerns have escalated that government employees with access to nonpublic policy information—including regulatory deliberations, fiscal decisions, or enforcement actions—could use that knowledge to profit before the information becomes public. Existing federal securities law prohibits insider trading in traditional financial markets, but the application to political prediction markets has remained legally ambiguous, creating a gap that state-level bans are now designed to close.

The implications extend beyond New York and Illinois. Other states may face pressure to adopt similar prohibitions as prediction markets continue to attract mainstream participation and as federal officials—including members of Congress—have faced scrutiny over their own trading activity in related markets. The bans signal that state regulators view political prediction markets as falling within the spirit of insider trading restrictions, even if the legal framework remains untested. Whether this leads to broader federal guidance or a patchwork of state rules will depend on how the markets develop and whether federal regulators choose to act.
