- New York alleges Kalshi operates an unlicensed gambling business through prediction markets.
- The CFTC argues federally regulated event contracts should remain under federal oversight.
- The lawsuit could influence the future regulation of prediction markets across the U.S.
New York has launched a legal challenge against prediction market platform Kalshi, accusing the company of running an unlicensed gambling business through contracts tied to sports, elections, and other real-world events. The lawsuit marks another major development in the ongoing debate over whether prediction markets should be regulated as financial products or treated as gambling under state law.
The case could shape the future of event-based trading platforms across the United States, especially as federal regulators and state authorities continue to disagree over who has jurisdiction.
New York Seeks to Shut Down Kalshi’s Operations
New York Attorney General Letitia James announced the lawsuit on Friday, arguing that Kalshi’s event contracts amount to illegal gambling under state law. The state is seeking to halt the company’s operations in New York, recover alleged unlawful profits, provide restitution to affected users, and impose civil penalties worth three times those gains.
The lawsuit follows a cease-and-desist order issued by the New York State Gaming Commission in late 2025. Kalshi challenged that order in federal court, but its attempt to block enforcement was rejected by both a district judge and a federal appeals court.
The legal action adds further pressure on a platform that has increasingly found itself at the center of regulatory scrutiny.
Federal Regulators Push Back Against State Enforcement
The dispute extends beyond New York. The Commodity Futures Trading Commission (CFTC) has argued that prediction markets operating as federally regulated exchanges fall under federal oversight rather than individual state gambling laws.
Just before New York filed its lawsuit, the CFTC submitted an emergency motion seeking to stop the state’s enforcement efforts. The agency maintains that allowing each state to regulate federally approved event contracts independently would create conflicting rules and weaken the national commodities framework.
The disagreement highlights a growing legal conflict over how innovative financial products should be supervised as prediction markets gain popularity.
Prediction Markets Continue to Expand
Despite mounting legal challenges, prediction markets have continued attracting users worldwide. These platforms allow traders to buy and sell contracts linked to future events, with market prices reflecting collective expectations about likely outcomes.
Kalshi has also expanded its blockchain strategy, launching tokenized prediction markets on Solana before broadening support to additional blockchain networks.
Meanwhile, competitor Polymarket has faced regulatory investigations in several countries over licensing and gambling concerns. Even so, the sector has experienced significant growth. Data from Chainalysis estimates blockchain-based prediction markets processed roughly $20 billion in trading during the 2026 FIFA World Cup, involving more than 400,000 participating wallets.

New York’s lawsuit against Kalshi represents more than a dispute involving a single company. It underscores the broader legal battle over who controls the future of prediction markets in the United States. As state regulators, federal agencies, and blockchain-powered platforms continue to clash, the outcome could establish an important precedent for how event contracts are regulated and traded in the years ahead.
