Governors Hochul and Pritzker Issue Executive Orders Banning Insider Trading on Prediction Markets

New York and Illinois governors issued the first US executive orders specifically targeting prediction market insider trading by state employees, prohibiting officials from using non-public government information to trade event contracts.

New York Governor Kathy Hochul and Illinois Governor JB Pritzker issued executive orders in the final week of April 2026 prohibiting state employees and officials from using non-public government information to trade event contracts on prediction market platforms. The orders are the first gubernatorial actions in the United States specifically targeting prediction market insider trading and were issued within 48 hours of the Fort Bragg arrest of Master Sergeant Gannon Ken Van Dyke.

Hochul's order covers all New York state employees, contractors, and political appointees. Senior officials are required to disclose prediction market holdings. The order does not prohibit participation outright but creates a legal basis for prosecuting officials who trade on non-public state information under existing corruption statutes. "Getting rich by betting on inside information is corruption, plain and simple," Hochul said.

Pritzker's Illinois order mirrors the New York framework, adding targeted restrictions on procurement officials and financial regulators whose advance knowledge of government decisions could provide tradeable market advantages. Both governors cited the Van Dyke case as a catalyst, though advisers to both offices noted the orders had been in preparation before the Fort Bragg arrest became public.

Neither order creates automatic criminal liability, but both establish enforcement pathways for state attorneys general. Illinois AG Kwame Raoul and New York AG Letitia James have each indicated they are reviewing prediction market trading records for state officials. Legal observers expect the first state-level enforcement actions under the orders to materialize within 60 to 90 days, most likely in cases where the link between an official's government role and their market positions is clearest.

Missouri AG Sends Cease-and-Desist Letters to Six Prediction Market Operators

Missouri Attorney General Catherine Hanaway issued cease-and-desist letters on September 18 to six prediction market operators — Kalshi, Polymarket, Robinhood, Crypto.com, Novig, and Underdog — alleging their sports event contracts constitute unlicensed sports wagering under Missouri law. The letters give platforms 30 days to comply or obtain licenses from the Missouri Gaming Commission. Missouri is the broadest multi-platform C&D action to date, targeting all major operators simultaneously. The action arrives one day after Montana and Kalshi filed a joint stipulation in which Montana agreed to pause enforcement while Ninth Circuit en banc review is pending.

Yahoo Finance Ends Polymarket Data Partnership After Five Months

Yahoo Finance and Polymarket mutually ended their prediction market data partnership on September 18, approximately five months after the companies announced an exclusive arrangement in November 2025. The Polymarket data hub that Yahoo Finance launched in January-February 2026 was quietly taken down in April 2026. No reason was publicly disclosed. Yahoo Finance retains an advertising relationship with Polymarket. The partnership's end is a setback for Polymarket's strategy of embedding its probability data into mainstream financial media platforms.

Montana and Kalshi Reach Joint Stipulation — State Pauses Enforcement Pending Ninth Circuit En Banc

Kalshi dismissed its lawsuit against the Montana Department of Justice on September 17 after both sides filed a joint stipulation in which Montana agreed to pause all enforcement, investigations, and cease-and-desist proceedings against Kalshi's event contracts. The pause lasts until the Ninth Circuit either denies en banc review of the August 28 ruling or issues an en banc decision. Montana must give Kalshi 30 days written notice before resuming any enforcement action after that window closes. The agreement mirrors the Robinhood-Michigan stipulation from September 4 and reinforces a pattern of states reaching negotiated compliance pauses while the appellate process plays out.
