- Daniel Yee filed a federal lawsuit against Kalshi Inc., alleging the company misled users by promoting unregulated sports betting as legal.
- Yee claims Kalshi violated state laws by operating without proper sports betting licenses in states like California and New York.
- The lawsuit seeks a nationwide class action to recover user losses and prevent Kalshi from falsely marketing its services.
SACRAMENTO, Calif. – Daniel Yee filed a lawsuit against Kalshi on Thursday, alleging that the platform misled users by advertising its “event contracts” as legally valid sports betting. The complaint seeks injunctive relief and compensation for users who believed they were legal sports betting in the US under a license.
Key Allegations & Claims
Yee contends he lost approximately $2,000 playing on Kalshi’s markets, and that Kalshi’s advertising implied legality in states with sports betting heavily regulated under gaming commissions.
In his complaint, he argues that Kalshi’s product is not an abstract derivatives market but an unlicensed sportsbook in disguise.

If his motion is granted, Yee hopes to assist a nationwide class of users were similarly misled.
Though Kalshi is registered under oversight by the Commodity Futures Trading Commission (CFTC), Yee’s filing argues that Kalshi’s conduct improperly straddles the line between federally regulated derivatives and state-regulated gambling. He asserts that state laws and licensing requirements were glossed over in Kalshi’s marketing, particularly in states like California and New York.
Parallel Regulatory Battles & Kalshi’s Legal Strategy
Kalshi’s legal stance is bolstered by ongoing litigation with state regulators across the country. In Nevada, a U.S. District Court granted Kalshi a preliminary injunction preventing the state from enforcing cease-and-desist orders on its sports-style event contracts, citing that Kalshi’s operations fall under “federal domain”.
Kalshi has also sued regulators in New Jersey, Maryland, and Ohio, maintaining that state attempts to regulate or ban its event contracts are preempted by the Commodity Exchange Act (CEA) and the exclusive jurisdiction granted to the CFTC.
Some states, like Massachusetts, have moved in the opposite direction and sued Kalshi, alleging it is effectively operating as a sportsbook without a license.
