New York Attorney General Petitions Court to Compel Kalshi Compliance with Advertising Subpoena
New York AG Letitia James petitioned on Nov. 2 to enforce a Sept. 25 subpoena against Kalshi after zero documents were produced by the Oct. 5 deadline. The demands target advertising, influencer deals, trading records, incentives, and "no house" claims. This adds to existing state lawsuits, a denied injunction, CFTC intervention, and a Nov. 3 appeal hearing.
SCCG Take — Prediction market operators must treat state advertising subpoenas as immediate operational risks that can multiply into parallel litigation. The Kalshi matter shows federal CFTC approval does not insulate platforms from aggressive state enforcement on marketing mechanics.
New York Attorney General Letitia James filed a petition in state court on November 2 seeking an order to force Kalshi to comply with a subpoena issued September 25. The company produced no responsive documents by the October 5 deadline. The action centers on allegations of misleading marketing practices and questions the operator's "no house" claims.
The petition targets materials related to consumer-facing promotions that may overstate typical user outcomes. It forms the latest escalation in parallel state and federal proceedings that already include an unsuccessful injunction bid and a separate lawsuit.
Subpoena Demands and Specific Allegations
The September 25 subpoena seeks records on advertising and influencer promotions, including all marketing materials, agreements, payments, and linked trading activity. It further demands internal marketing policies, training materials, and guidance; documents on proprietary trading and market making plus third-party liquidity arrangements; details of incentive programs for volume, liquidity, combo, and market-maker offers; and any prior disclosures to other regulators.
James' filing cites social media advertisements in which users claimed earnings sufficient to cover rent or replace employment income. It contrasts those depictions with reports that a small number of sophisticated traders generate most platform profits. The petition also challenges Kalshi's "no house" representations in light of its affiliated market maker, Kalshi Trading. Kalshi moved October 30 to quash the subpoena, arguing overlap with the existing enforcement action. The petition requests production within 10 days of any court order.
Status of Parallel Proceedings
A federal judge denied Kalshi's July motion for a preliminary injunction against state officials. The U.S. Court of Appeals for the Second Circuit rejected an injunction pending appeal, with a hearing set for November 3. James' office then filed a state-court lawsuit that Kalshi removed to federal court. The CFTC intervened in the dispute and issued an emergency order directing Kalshi to maintain contract access in New York. Separately, the New York State Gaming Commission sued to enforce subpoenas on sports contracts, advertising, and underage-user issues. The New York City Council opened its own inquiry into marketing practices in August.
According to reporting by Gambling Insider, these overlapping actions illustrate sustained regulatory examination of prediction-market operations and consumer disclosures. The combined pressure leaves Kalshi defending its model on multiple fronts while its Second Circuit appeal proceeds.
The Regulatory Exposure Ahead
With multiple subpoenas and lawsuits now active, the dispute tests the boundary between CFTC-regulated event contracts and state gambling enforcement. Operators in this space face concrete compliance costs and litigation risk when advertising claims attract attorney general attention. How courts reconcile the federal emergency order with New York's demands will shape the practical scope of prediction-market activity in contested jurisdictions.
