New York sues Kalshi, escalating state-federal prediction market clash

New York state filed a lawsuit on Friday against prediction market Kalshi, accusing the New York City-based company of operating an illegal gambling business. The case, brought in a Manhattan state court, seeks a permanent injunction to halt Kalshi's operations.

The financial exposure for the platform is severe. New York is pursuing a $100,000 penalty for every attempt to offer sports wagering, alongside treble damages equal to three times the company's allegedly ill-gotten gains. The state is also demanding total restitution for users who placed trades on the platform.

While the surge in retail trading of sports-related event contracts triggered the legal action, the state's claims extend well beyond athletics. The lawsuit argues that Kalshi's contracts on elections, culture, and other events also violate state gambling laws by bypassing the New York State Gaming Commission.

The legal assault targets a sector that has recently seen trading volumes surge. If New York succeeds, it could force a fundamental restructuring of how these federally licensed exchanges operate, effectively locking them out of a major financial hub.

The case marks an escalation in a jurisdictional war between state and federal regulators. Kalshi and the Commodity Futures Trading Commission classify all event contracts as swaps, placing them under exclusive federal oversight. States counter that sports offerings are identical to traditional sports betting, a domain they strictly control.

Friday's lawsuit follows a series of federal courtroom defeats for Kalshi. A Southern District of New York judge recently denied the company's requests for a temporary restraining order and an injunction pending appeal after Kalshi preemptively sued the state in October.

Just before New York announced its suit, the CFTC filed its own motion for a temporary restraining order to block state enforcement. This builds on an April lawsuit where the CFTC sought a permanent injunction to stop New York from applying its laws to commission-registered platforms.

"No matter what they call themselves, prediction markets like Kalshi are gambling platforms, plain and simple," Attorney General Letitia James said. Governor Kathy Hochul stated the action is intended to force the company into compliance with state law.

Kalshi dismissed the lawsuit as political overreach. "States can't just shut down a federally licensed exchange," a company spokesperson said. The dispute arrives as 44 state attorneys general recently told the CFTC it lacks the right to regulate sports-related event contracts during a public comment period for the agency's first draft of prediction market regulations.
