New York Investigates Kalshi Over Advertising and Business Practices
United States.- 4 November 2026 | www.zonadeazar.com The New York Attorney General’s Office, led by Letitia James, has filed a court petition seeking to compel Kalshi to provide documents concerning its advertising practices, influencer relationships and market-making activities.
The filing, submitted on 2 November 2026, forms part of an investigation into potentially misleading commercial representations and transparency within prediction markets.
The proceedings add to the regulatory disputes facing the company across several US states.
New York Demands Documents from Kalshi
The Attorney General’s Office filed a petition in state court seeking enforcement of a subpoena issued on 25 September 2026.
According to the authorities, Kalshi failed to provide the requested documents by the 5 October deadline.
The investigation seeks to determine whether the company or third parties acting on its behalf made false or misleading advertising statements or omitted material information.
The Attorney General has asked the court to order production of the documents within ten days.
Advertising and Influencers Under Investigation
The subpoena covers several areas of Kalshi’s promotional activities.
The requested documentation includes:
- Influencer contracts and payments.
- Advertising materials and promotional campaigns.
- Trading activity by individuals hired to promote the platform.
- Internal marketing policies.
- Commercial incentive programmes.
The investigation focuses particularly on social media promotions highlighting substantial profits from prediction market contracts.
Some advertisements referenced in the filing feature users claiming to have earned enough money to pay their rent or replace employment income.
The authorities want to establish whether such communications adequately represent the risks associated with these products.
Attorney General Examines Market-Making Activities
Another important aspect concerns Kalshi’s description of its operating model.
The company presents its platform as a marketplace where participants trade contracts with one another, distinguishing it from traditional house-backed gambling.
However, the Attorney General is seeking information concerning Kalshi Trading, an affiliated market-making entity.
The subpoena also requests details of agreements with external liquidity providers and incentive programmes for professional market participants.
The investigation aims to determine whether the company’s public explanations accurately describe its business structure.
The allegations remain under investigation and do not constitute judicial findings of wrongdoing.
Kalshi Challenges the Subpoena
On 30 October, Kalshi filed a request to block the subpoena.
The company argued that the request seeks information relating to matters already being litigated in separate proceedings.
The dispute reflects continuing disagreements between Kalshi and state authorities over the regulatory treatment of event contracts.
Kalshi maintains that its financial products fall under the federal supervision of the Commodity Futures Trading Commission (CFTC).
New York authorities, meanwhile, argue that certain activities may also fall within state gambling and consumer protection laws.
Legal Disputes Continue in New York
The latest investigation adds to previous proceedings involving Kalshi.
In July, a federal judge denied the company’s request for a preliminary injunction against state officials.
Kalshi subsequently appealed to the US Court of Appeals for the Second Circuit.
The Attorney General also initiated separate proceedings concerning sports event contracts offered within New York.
The New York State Gaming Commission has separately sought documentation concerning sports contracts, advertising and customers under the age of 21.
These cases illustrate the continuing dispute over the relationship between federal derivatives regulation and state gambling laws.
Industry Impact and Next Steps
The New York investigation introduces additional transparency demands for Kalshi amid the expansion of US prediction markets.
The proceedings could provide further information about marketing practices, influencer partnerships and the role of liquidity providers within these platforms.
With a subpoena targeting advertising, influencers and market-making arrangements, New York is intensifying scrutiny of Kalshi and the operation of prediction market contracts.
Upcoming developments will depend on judicial decisions concerning document disclosure and the progress of existing regulatory litigation.
