New York Sues Kalshi to Enforce Subpoenas in Regulatory Fight

The New York State Gaming Commission has petitioned a Manhattan court to compel prediction markets operator Kalshi to comply with subpoenas issued as part of an investigation into potential violations of state gambling law. This action follows Kalshi’s alleged refusal to provide requested records concerning its sports prediction markets.

What Happened

The New York State Gaming Commission (NYSGC) filed a verified petition in New York County Supreme Court on October 22, seeking to force Kalshi to produce records related to its sports prediction markets. The commission alleges that Kalshi has withheld information critical to its investigation into potential violations of state gambling law, according to SBC Americas. The subpoenas, issued on July 31 with an August 14 return date, followed a federal district court’s denial of Kalshi’s request for a preliminary injunction against state enforcement.

The NYSGC asserts that Kalshi has “flatly refused to produce any documents in response to Requests one through five or ten through twelve,” which are deemed relevant to the investigation into Kalshi’s mobile sports wagering operations in New York. The regulator is seeking a court order requiring Kalshi to respond to these information requests and produce all responsive, nonprivileged documents within 10 days of such an order. New York Attorney General Letitia James’ office is representing the gaming commission in this proceeding, as reported by SBC Americas.

Key Details

• The NYSGC’s subpoenas requested information on advertising describing Kalshi’s products as bets or wagers, products offered to New Yorkers under 21, sports event contracts, and the company’s ownership and corporate structure, according to the petition cited by SBC Americas.
• Kalshi reportedly objected to requests concerning users younger than 21, asserting that such inquiries “presuppose a gaming-age framework inapplicable to a CFTC-regulated exchange.”
• The company also objected to providing stock ownership information, deeming it “confidential and competitively sensitive investor and capitalization information,” which implicates the privacy interests of investors not party to the proceeding.
• The commission argues that ownership details could aid in identifying parties responsible for potential violations and uncover additional investigative avenues involving other entities and individuals.

Why It Matters

This dispute adds a document production element to the ongoing jurisdictional debate over whether New York can regulate Kalshi’s sports contracts. The NYSGC states it requires these records to determine if civil penalties are warranted and, if so, their specific amounts. Kalshi, conversely, maintains that its event contracts are federally regulated financial products and thus not subject to state gambling regulation. This subpoena enforcement proceeding is separate from earlier federal litigation regarding regulatory authority, including Kalshi’s previous lawsuit against the state following cease-and-desist orders issued in October 2025.

What’s Next

The immediate goal of the NYSGC is to secure a court order for document production, not to impose civil penalties at this stage. The broader jurisdictional conflict over sports event contracts, which involves the Commodity Futures Trading Commission (CFTC) suing New York to assert federal authority, appears to be moving towards a potential review by the U.S. Supreme Court, as reported by SBC Americas.
